1.1 Health and Safety AmbiRad heaters must be installed in accordance with the relevant provisions of the Gas Safety (Installations and Use) Regulations 1998. Due account should also be taken of any obligations arising from the Health and Safety at Works Act 1974 or relevant codes of practice. In addition the installation must be carried out in accordance with the current IEE wiring regulations (BS 7671), BS 6896: (Industrial & Commercial) and any other relevant British Standards and Codes of Practice by a qualified installer. Isolate all electrical supplies to the heater & controller before proceeding.
Introduction. number of radiant branches manifolded together, linked by a tail pipe to a vacuum fan discharging the spent products of combustion to atmosphere. A system may comprise of just one burner and one vacuum fan, to multiple burners in multiple radiant branches with one or more vacuum fans. To enable exact matching of operational needs within an area, distances between burners and ratings of the burners can vary. The unique feature of Nor-Ray-Vac ‘LR’ series is a radiant system which provides uniform heat coverage of the floor area, eliminating hot/cold spots. The tube into which the burners are mounted and over which the reflectors are fitted and emits the maximum heat is called the radiant tube. The radiant heat emitted from the hot tube is directed downwards by reflectors. The remaining interconnecting tube is called the tail pipe and radiates with less intensity. The operating temperatures of the tubes generally range from 200°C – 480°C max. The action of the vacuum fan is three fold; to create a high negative pressure within the radiant tube and tail pipe so as to discharge the spent products of combustion from the system to a point outside the building being heated; to control the flow of gas and air through each burner in stoichiometric proportions; to draw carrier air into the tube system at the start of each radiant branch, in order to distribute the heat from the flame along the tube.
Welcome to the range of Nor-Ray-Vac ‘LR’ series continuous radiant tube heaters. The Nor-Ray-Vac ‘LR’ series system complies with the requirements of the European Gas Appliance Directive BS EN777-4. Local regulations may vary in the country of use and it is the installers responsibility to ensure that such regulations are satisfied. All installation, assembly, commissioning and service procedures must be carried out by suitable qualified competent persons to the statutory regulations in the country of use. When assembling, installing, commissioning and servicing is undertaken on radiant tube heaters specified in these instructions, due care and attention is required to ensure that working at height regulations are adhered to at the mounting heights specified.
PLEASE READ this document prior to installation to familiarise yourself with the
components and tools you require at the various stages of assembly. All Dimensions shown are in mm unless otherwise stated. The manufacturer reserves the right to alter specifications without prior notice. The Ambi-Rad Nor-Ray-Vac ‘LR’ series direct gas fired radiant heating system comprises of a continuous system with a number of burners located in series in a radiant branch, and a
The system is assembled at high level suspended by chains from first fixings to the roof structure. (First fixings by others)

1.3 Heater Suspension 1.3.1 First considerations • Clearances from combustibles must be
maintained. (See figure 2) • For ease of servicing there should be a
minimum clearance distance of 500mm between the burners of the heating system and the building wall. This measurement can be reduced for perimeter type systems. (See figure 1a).
• For ease of servicing and burner removal minimum clearances should be maintained. (See figure 1b and 1c). In exceptional circumstances the burner lid may be slid diagonally for removal thus reducing the vertical distance.
• Ensure that the suspension is sufficiently flexible to allow for thermal expansion.
1.3.2 Suspending the heater - General 1.3.2.1 The first support is always positioned at the support lug suspension point on the end vent burner combustion chamber. 1.3.2.2 Subsequent supports are placed approximately 2.8m apart, including one at each combustion chamber location. This gives a maximum load per support of 24kg.
1.3.2.3 A support must always be located at a maximum distance of 2m from a tee or elbow fitting. 1.3.2.4 Except for the combustion chamber support lug suspension points, suspension support brackets are installed to support the tube section which is then covered with reflectors. 1.3.2.5 Tail pipe hangers are installed for the tube section which will be without reflectors. If there are any doubts as to the strength or suitability of roof steelwork to which heaters are to be suspended, please refer to a Consultant, Architect or owner of the building. Table 1.

Take care when making a gas connection to the heater not to apply excessive turning
force to the internal controls. A flexible hose is installed to allow safe linear expansion to each burner without creating undue stress on the gas supply pipe work. It is therefore important that a tested and certified hose assembly made to ISO 10380, supplied with ½” BSP female cone seat adapters, is installed as per these instructions. It is also important to ensure that expansion is taken up in the body of the flexible hose, and not on its attachment to the pipe work. The cone seat adapter supplied on one end of the flexible gas hose provides a `swivel` action, and must be fitted on the burner using a ½” BSP barrel nipple to provide ease of disconnection for future servicing.
The installation layout described below is the only method recommended by the
institute of gas engineers, the hose manufacturer, and AmbiRad and must only be carried out by a qualified/competent gas engineer.
1.5 Gas Connection and Supply
A competent or qualified engineer is required to either install a new gas meter to the service pipe or to check that the existing meter is adequate to deal with the rate of gas supply required. Installation pipes should be fitted in accordance with BS 6896, so that the supply pressure, as stated in Table 3 will be achieved. It is the responsibility of the competent engineer to ensure that other relevant Standards and Codes of Practice are complied with in the country of installation. Pipes of smaller size than the heater inlet gas connection must not be used. The complete installation must be tested for soundness as described in the country of installation.
The gas union service cock MUST be fitted in the gas supply close to the heater, but not onto the burner itself.
Before installation, check that the local distribution conditions, nature of gas and pressure, and adjustment of the appliance are compatible.

Depending on the specific installation, the flexible gas hose may be routed to the gas cock at any of the following angles in relation to the burner: Vertical (fig.a) 45° angle (fig.b) 90° angle (fig.c) Any other position in between these angles is acceptable. Care must be taken to observe the minimum pipe bend diameter (minimum 250mm, maximum 350mm) & pipe expansion distance (minimum 30mm, maximum 70mm) as shown in fig.e.
Maximum bend diameter for the hose is 450mm. The correct installation as shown will allow for approx 100mm of movement due to
expansion.

Figure 4.a. Typical Wiring Connections
1.6 Electrical Connections Standard burner 16W. Current rating 0.05 amp per burner Fuse: external 3 amp. Each component carrying an electrical supply must be earthed. Supply for burners is 230V 50Hz single phase. * Exhaust fans are three phase 415V 50Hz. * IP54 rated Inverter panel LRU’s require a 230V single phase supply at 22A (B80/B160) or 30A (B300) * Standard LRU’s require a 415V three phase supply at 25A (BH300) * refer to individual site specifications All electrical work should be carried out to IEE standards by a competent electrician. The electrical connection to the burner is made by means of a three pin plug-in power connector. Live, neutral and earth connections should be made via a flexible supply cable to the power connector and routed clear of the heater or tubes. The flexible supply cables to each burner
should be of 0.5mm² minimum and comply with BS 6500:2000. For fan and LRU supply, the wire size must be suit-able for the current rat-ings as listed in Table 10. The wires in the mains lead are coloured in accordance with the following code: Green & Yellow Earth; Blue Neutral; Brown Live
The method of connection to the electrical supply must facilitate complete isolation and should be via a fused double pole isolator having contact separation of at least 3mm on all poles and supplying the appliance only. We recommend use of AmbiRad approved controls. Please refer to; SmartCom control manual for siting and installation details and figures 4.l and 4.m Where alternative controls are used, please refer to the manufactures instructions for their siting and installation details.

1.7 Ventilation Requirements Nor-Ray-Vac heaters are installed as flued appliances in accordance with the relevant national requirements in the country of installation. In buildings having an air change rate of less than 0.5 per hour, additional ventilation is required. For detailed information, please see BS6896 section 5.2.2.2.1 Natural Ventilation Low level ventilation openings with a free area of at least 2cm²/kW shall be provided. See BS6896 section 5.2.2.2.2.1. 1.8 Exhaust and Air Inlet - Options 1.8.1 Horizontal discharge
Considerations. The vacuum fan must be located as shown in the layout drawing. The vacuum fan must have a bottom horizontal discharge. The fan should be fitted to the mounting platform which is fixed to the wall or building structure. Alternatively, the fan can be suspended from the roof structure, via drop rods (not supplied) and mounted on base frame. (Anti-vibration mountings are fitted between the fan and the mounting platform/base frame. For full details of parts and installation, please refer to section 2.9.3
1.8.2 Vertical discharge
20
1.8.3 Ducted Air Inlet Considerations. Heat resistant flexible tube is connected to the burner assembly ducted air adaptor and the EVM ducted air adaptor and connected to the air supply duct The maximum length of 100mm diameter ductwork is 2m. Ensure that the flexible supply duct does not drape over or touch the reflector.
Ensure that the flexible ductwork is installed to allow for expansion of the heating system. On a header duct, the main air supply header which is feeding the individual branch ducts and burner/end vent supply ducts must have a maximum pressure drop of 0.25 mbar (0.1in wg). All joints and seams in the air supply system must be made air tight and a bird screen used at the inlet. For full details refer to section 2.13

2.1 Tools Required. The following tools and equipment are advisable to complete the tasks laid out in this manual.
2.2 Assembly Notes.
2.2.1 Radiant Tubes
All radiant tubes are 101mm (4”) O/D, ERW steel to BS 6323:Part 5: are factory pre-painted and supplied in 5.2m lengths. These may need to be cut depending on the system drawing design.
Note: on assembly, tube seams to be facing upwards.
The system is assembled at high level suspended by chains from first fixings to the roof structure. (First fixings by others)
Combustion chambers are 2.6m in length and increase in
diameter to 127mm (5”) around the burner turret.
All tubing, combustion chambers, dampers and tube fittings are connected by ‘wrap-around’ stainless steel couplers which clamp by means of two high tensile stainless steel set pins. (See section 2.2.2)
Please read these assembly notes in conjunction with the correct assembly drawings (Sections 2.2.1 to 2.21.1)
Burner Combustion Chamber
27
2.2.2 Couplers The Nor-Ray-Vac Tube Coupler is a screw tightening, self aligning - positive located tubular coupler. Manufactured in a non–corrosive stainless steel it is available in both 100mm (4”) and 150mm (6”). Two high tensile stainless steel set pins tighten to clamp the coupler onto the tube whilst a rivet provides a centralised permanent stop to give the joint equidistance. The following procedure explains the correct method of assembly: Before assembly, carefully loosen the two screws. Position the coupler onto the first tube ensuring that the bars are positioned uppermost.
Slide the coupler over the tube ensuring that the rivet stop has butted up to the tube end.
Using a 6mm allen key, tighten the relevant pin. DO NOT OVERTIGHTEN.
Slide the second tube into the coupler ensuring that the rivet stop has butted up to the tube end.
Using the 6mm allen key, tighten the second pin. DO NOT OVERTIGHTEN.
Moving between the two set pins, tighten both ensuring that equal pressure is applied to each set pin in turn.
If all steps have been followed correctly, the coupler should have aligned itself parallel to the two tubes and a slight indentation can be observed. Using the 6mm allen key, finally tighten each screw by a further quarter turn. If a power tool is used, use a torque limit setting of 6.6 lbf/ft (0.91kgf/m) must be achieved.

2.2.3 Reflectors The radiant tube sections of the system are fitted with reflectors made of either stainless steel or aludip to direct infra-red rays downwards. The reflectors have a unique design profile to maximise the reflected radiant heat, minimise convective loss, and maximise on rigidity. The reflectors are overlapped and held in position by the reflector bracket assembly. There are two styles of reflectors: 2.2.3.1 Standard Reflectors These 2.4m long reflectors are positioned above the tube to radiate the heat downwards and are fixed to the radiant tube via a reflector bracket (see section 2.5). The combustion chamber reflector has a rectangular hole and slot, pre cut to allow for burner combustion chamber and support lug fitting.
2.2.3.2 Perimeter Reflectors Perimeter reflectors are used when the radiant tube is mounted at the perimeter of the building. They have the same profile as standard reflectors but extended one side to direct the radiant heat away from the wall. The perimeter combustion chamber reflectors have a cut-out for the combustion chamber turret and suspension lug at both ends so that the one reflector can be used for either left or right hand perimeter systems.
2.2.3.3 Corner Reflectors Used where radiant tubes are joined with a 90° bend. The corner reflector comes in two pieces and is assembled on-site.
2.2.3.4 Tee piece Reflectors Used where a radiant tube connects to another at right angles. The reflector is a special short section with a central tube cut out.
2.2.4 Brackets There are two styles of brackets: 2.2.4.1 Suspension brackets. Suspension brackets are made from a one piece construction and are formed to support the tube and reflector alike. The wrap around ends are aligned to hold a turnbuckle eyelet in the correct hanging position.

Corner Reflector
Tee section
Note: when overlapping the perimeter combustion chamber reflector, extra overlap is required to cover the pre-cut holes and slot.
Standard Suspension Bracket
29
A perimeter suspension bracket is available which has the same profile as the standard brackets but extended one side to accommodate the perimeter reflector.
2.2.4.2 Reflector Support Bracket Reflector Support Brackets are a two piece construction. The first half is formed to seat on top of the radiant tube and supports the reflector sides in position. The second part clamps around the bottom half of the tube and is fixed in position via a fastener.
The reflector support bracket has two functions depending on the position of the fixing screws. 1. To fix the reflector into position. 2. To allow the reflector to slide within the
bracket for thermal expansion. A perimeter reflector support bracket is available which has the same profile as the standard brackets but extended one side to accommodate the perimeter reflector.
2.2.4.2.1 Attachment of reflector bracket. Fit the reflector bracket (B) around the tube and tighten the set pin (D) to clamp the central clip (C) to the tube. The set pins (A) positioned at both edges of the bracket (B) are used to provide either a fixed joint or a sliding joint.
Fully tighten these screws for fixed joints.
Leave a minimum 3mm gap clearance between reflector and screws for a sliding joint.
The reflector overlap after each burner must be a ‘sliding joint’, to allow for thermal expansion.

The next downstream reflector overlap must be a ‘fixed joint’. This pattern of alternate sliding and fixed joints will continue up to the next in line burner or damper assembly. A reflector support bracket must be positioned at the end vent and at the damper end of each radiant branch, plus either side of a reflector corner and reflector tee section. These units must be ‘fixed joints’. 2.2.5 Burner 2.2.5.1 LR Burner Unit Each burner will consist of: A burner control housing (BCH) of chassis style with detachable pivoting lid. All control wiring to the burner head is within the BCH, which also contains a combination gas valve comprising of 2 class 2 solenoid valves, dedicated zero governor and filter, a full sequence controller and cassette air filter for primary air supply to the burner. Externally on the BCH, neon lights indicate mains on and burner on modes. The air and gas are pre-mixed to stoichiometric proportions within the burner head assembly, prior to being admitted to the point of combustion. Ignition is by an electric arc forward of the face of the burner head on to the main frame.
2.2.5.2 Burner Head A burner head assembly of lightweight cast aluminium construction, a ceramic style burner head insert, maintained in position by the flame retention grid. The casting assembly also accommodates the gas jet, air shutter and mixing chamber.
The ignition and flame sens ing e lec t rode assembly is mounted to the casting flange of the burner face. 2.2.6 End Vent Module (EVM) At the start of each radiant branch an end vent module is connected to the rear of the first combustion chamber. The end vent module externally maintains the lines of the reflector profile.
To comply with European standards that state air flow must be proven in each radiant branch, the end vent burner incorporates an air pressure switch. The end vent module incorporates the flow sensing pipework carrier air orifice plate and optional silencer box to reduce noise levels. 2.2.7 Vacuum fans A low noise robust steel plate fabricated centrifugal fan coated with heat and corrosion resistant paint, capable of a static pressure of either 29 mbar or 45 mbar at 20°C and directly coupled to a totally enclosed motor to be fitted at the end of the tube system. The fan exhausts the products of combustion from the system discharging through an outlet flue pipe to atmosphere external to the building. The maximum operating temperature is 200°C. The fan motor is IP55 rated for external use.

3. Commissioning Instructions. These appliances should be commissioned by a qualified engineer.
3.1 Tools Required. The following tools and equipment are advisable to complete the tasks laid out in this manual.
Suitable alternative tools may be used.
Manometer
Allen Key set
Spanner Set
3.2 General. Under normal working conditions it is recommended that the Nor-Ray-Vac ‘LR’ series system is regularly maintained to ensure long life and efficient operation. Maintenance is required only once per year. In dusty or dirty conditions more frequent maintenance is desirable. Servicing work must be carried out by a qualified gas service engineer.
Important
When maintaining or servicing the Nor-Ray-Vac ‘LR’ series systems: • Never rest anything, especially ladders
against heating system. • Isolate gas and electrical supplies before
commencing any service work. 3.3 Commissioning Procedure 3.3.1 Start Up Checks 3.3.1.1 Check that the installation is to the design layout drawing and installed in accordance with the installation instructions. 3.3.1.2 Check installation electrically. Ensure that the vacuum fan, inverter, burners and control panel are wired correctly to diagrams provided. 3.3.1.3 Ensure that each burner is electrically disconnected at the plug/socket. 3.3.1.4 Set individual burner delay timer dip-switches (located in each burner) to required
setting. Refer to section 3.3.1.8 3.3.1.5 Check gas is turned on at meter and take meter gas pressure reading. Fit pressure manometer to the inlet pressure test point on the burner furthest from the gas supply and with all burners off observe pressure reading. Turn off gas at meter and again observe reading. If pressure falls check system for leaks.
The gas pressure at the burner inlet connection must not exceed 50 mbar (20in wg). 3.3.1.6 Start the vacuum fan. For various controllers/BMS systems it may be necessary to adjust the set point to above room temperature. For B80/B160 and B300 fans with an inverter panel, check that the display states “rdy” (ready) 3.3.1.7 Check for correct fan rotation.

3.3.1.9 Adjust the vacuum setting The end vent vacuum is measured by removing the protection cap on the tee piece in the air impulse line on the end vent burner and connecting a manometer.
3.4 B80/B160 and B300 fans ONLY The use of an inverter on the standard B80, B160, B300 fan system allows the end vent suction to be adjusted by varying the low speed setting of the inverter within the local relay unit. 3.4.1 Ensure that electrical supply to the end vent modules and burners in each branch are connected. 3.4.2 Check that the fan and branch dampers are fully open and secure. 3.4.3 Ensure the controller is in a programmed ON function and above the actual room temperature. 3.4.4 After a 30s delay the fan should run and the inverter should be showing the motor frequency in the display. 3.4.5 Press the mode button 3 times until ‘COnF’ appears on the display.
3.4.6 Press the jog dial to enter. Rotate jog dial until ‘LSP’ is displayed. Press jog dial to enter. 3.4.7 Rotate jog dial to adjust frequency. Press jog dial to enter new value, causing the inverter to change its speed. 3.4.8 Adjust the frequency until each burner has lit. Frequency is usually between 35 and 50 (Hz) 3.4.9 Press the ESC button twice to return the inverter to the ’rdY’ display. 3.4.10 Remove power to the system and allow fan to halt. 3.4.11 Return power to system. After a 30s delay the fan should run and a red neon should have illuminated on the rear of each burner. 3.4.12 Working at the radiant branch FURTHEST AWAY from the fan, observe the ignition of the burners. An amber neon should illuminate on the rear of the burner. 3.4.13 If the dip-switches have been set correctly, the burner closest to the manifold (last on branch) should ignite first followed in order by every burner towards the end vent burner. Note: It may be necessary to temporarily break the union at a burner in order to purge the gas pipe of air. When the branch has been running for 30 minutes check the end vent vacuum reading. 3.4.14 Re-adjust the frequency on the inverter (if necessary) until the appropriate end vent suction is achieved, this is given in the table below.

3.4.15 Proceed to the next radiant branch closer to the fan and commission in the same manner, observing the ignition sequence of the burners and amber neon's. 3.4.16 Check the end vent vacuum reading. 3.4.17 Adjust the branch damper (if necessary) located at the end of the branch to bring the vacuum readings in line with the normal operating figure shown in the chart. Ensure that damper is locked securely after adjustment.
Adjustment instruction for branch damper. 1 Loosen grub screw (A). 2 Turn adjustment lever (B). 3 Position of damper blade is indicated by position of bent adjustment lever. 4 Tighten grub screw (A) to secure damper position. 3.4.18 Repeat for any further branches (where necessary), moving closer to the fan as each branch is completed. The vacuum setting procedure is now complete.
3.5 BH300 fans ONLY (and fans controlled by NRV ‘logic’ driven LRU’s with no inverter) End vent vacuum settings are made firstly by means of adjusting the damper at the vacuum fan inlet, this brings the end vent with the lowest reading to the normal operating vacuum. The dampers on each branch can then be adjusted to bring the vacuum readings in other branches to the normal operating figure. Ensure that all dampers are locked securely after adjustment. 3.5.1 Ensure that each burner is electrically disconnected at the end vent module plug/socket. 3.5.2 Check vacuum fan inlet and branch dampers are fully open in the first instance and secure. 3.5.3 Ensure the controller is in a programmed ON and above the actual room temperature.
The fan inlet damper is integral to the fan inlet condensate tee piece. 1 Loosen grub screw (A). 2 Turn adjustment lever (B). 3 Position of the damper blade is indicated by position of bent adjustment lever. 4 Tighten grub screw (A) to secure damper position when finished. 3.5.4 After a 30s delay the fan should run. 3.5.5 Working at the end vent burner FURTHEST AWAY from the fan, measure the vacuum pressure and adjust the fan inlet damper to obtain over 8.7 - 10 mbar (above 3.6in wg) WHEN COLD.

3.5.6 Remove power to the system and allow fan to halt. 3.5.7 Ensure that each burner is electrically re-connected at the end vent module plug/socket. 3.5.8 Return power to system. After a 30s delay the fan should run and a red neon should have illuminated on the rear of each burner. 3.5.9 Working once more at the radiant branch FURTHEST AWAY from the fan, observe the ignition of the burners. An amber neon should illuminate on the rear of the burner. 3.5.10 If the dip-switches have been set correctly, the burner closest to the manifold (last on branch) should ignite first followed in order by every burner towards the end vent burner. Note: It may be necessary to temporarily break the union at a burner in order to purge the gas pipe of air. Allow the branch to run for 30 minutes. 3.5.11 Recheck the end vent burner FURTHEST AWAY from the fan, measure the vacuum pressure. Adjust the branch damper (if necessary) to obtain the figure shown in the table below.
3.5.12 Repeat for any further branches (where necessary), moving closer to the fan as each branch is completed. The vacuum setting procedure is now complete.
3.6 Final Commissioning. 3.6.1 Check that the burner injector pressures are zero ± 0.25 mbar (±0.1in wg). Adjust if necessary.
3.6.2 Check operation of thermostat controllers a number of times, allowing the burner ignition cycle to complete each time, checking that each burner relights. 3.6.3 With all burners firing check the inlet gas pressure at the burner furthest away from the gas supply. The minimum inlet pressure is 17.5mbar for G20 (Nat Gas), 20mbar for G25 (Nat Gas) and G31 (Propane) and 25mbar for G30 (Butane). The difference between gas pressure at the burner, with all the burners on and all the burners off should not be more than 2.5 mbar (1in wg). 3.6.4 Take gas consumption meter readings for each separate NRV system or building heated ensuring all other loads are off. 3.6.5 After the system has reached equilibrium: take the following measurements. a The flue gas temperatures entering the vacuum fan. The flue gas sample point located on the vacuum fan tee is used. b The surface temperature of the underside of the tube at the end of each radiant branch. c The surface temperature of the underside of the tube at a point directly underneath each combustion chamber suspension lug. 3.6.6 Reset thermostat controllers to required setting. 3.6.7 Complete service report sheet.

8.1 To Start the Heater
1. Ensure that gas supply is turned on at each burner.
2. Switch on electrical supply to heaters. 3. Ensure that the controls are correctly set
i.e.;
• Clock is correctly set. • Heater program is correctly set. • Required room temp is correctly set
4. The vacuum fan will operate and at the
same time the red neon lights will illuminate at all burners. After 10 seconds the burners closest to the exhaust fan in each radiant branch will light, with both red and amber neons illuminated. After a further 25 seconds the next burner in line within each radiant branch will light and after a further 25 seconds the end vent burner will light.
5 If the lighting up sequence fails and lockout
occurs press the lockout reset button (if available), or switch off the electrical supply and restart after 40 seconds. If lockout occurs three times consecutively switch off and isolate the gas and electricity supplies.
Contact the AmbiRad Service department.
8.2. To Switch Off Heater
1. Switch off electrical supply to the heater. The burner will stop and the fan will shut off.
2. If the heater is to be switched off for periods in excess of one week it is highly recommended that both the gas and the electrical supplies are turned off.
8.3. Routine Maintenance between Service Intervals
After ensuring that the heater is cold and mains electric isolated, cleaning of the reflectors with a soft cloth and a mild detergent (non solvent based cleaners only) in water can be undertaken.
Additional removal of dust from the radiant tubes, burner and heat exchanger can be undertaken.
8.4 Frequency of Servicing
The manufacturer recommends that to ensure continued efficient and safe operation of the appliance, the heater is serviced annually by a competent person e.g. every year in normal working conditions but in exceptional dusty or polluted conditions more frequent servicing may be required.
The manufacturer offers a maintenance service.
Details are available on request.
For Service requirements, please contact AmbiRad.
