1 Introduction
1.1 Safety instructionsGUNTAMATIC heating systems represent state-of-the-art technology and meet all applicable safety regulations. The boiler and fuel supply system are electrically operated. Incorrect installation can endanger life and limb. Heating boilers are combustion systems and are potentially dangerous if handled incorrectly. Installation, commissioning and servicing must, therefore, only be carried out by adequately qualified technicians observing all regulations and the manufacturer's instructions.
1.2 GuaranteeThe manufacturer's guarantee is subject to correct installation and commissioning of the heating system. Defects and damage caused by incorrect installation, commissioning or operation are not covered by the guarantee. To ensure that the system functions as intended, the manufacturer's instructions must be followed. Furthermore, only genuine replacement parts or parts explicitly approved by the manufacturer may be fitted to the system.
1.3 Site requirementsWhen establishing the site requirements, it is absolutely essential to take account of the locally applicable planning, building and implementation regulations and the dimensional specifications in the fitting guidelines, installation examples and technical data. Compliance with the locally applicable regulations and the correct implementation of the measures required on site are solely the responsibility of the system owner and are a requirement of the manufacturer's guarantee. GUNTAMATIC provides no guarantee of any kind for any type of site work. Without making any claims as to completeness or non-applicability of official requirements, we recommend the following specifications based on the Austrian Guidelines pr TRVB H 118:

1.3.1 Boiler room requirementsConcrete floor, bare or tiled, all materials for floor, walls and ceiling must be fire-resistant to F30 rating. The boiler room door must be a Class T30 fire door which opens in the direction of escape and is self-closing. Connecting doors to the fuel storeroom must also be Class T30 fire doors, self-closing and lockable. The pressure in the boiler room must not be less than 3 Pa (0.3 mm H2O). The air vents for boiler rooms must have a clear, net cross-sectional area of at least 200 cm and must not be sealable. When installing combustion boiler systems with a fuel heat output upwards of 50 kW, the net, clear cross-sectional area must be increased to at least 5 cm per kW rated output according to the combustion air requirement of the boiler system. The air supply ducting must connect directly to the outside and if the ducting passes through other rooms, it must be jacketed to Class F90. On the outside of the building, air vents must be covered by a protective grille with a mesh size of > 5 mm. The lighting and the electrical wiring in the boiler room must be permanently installed. There must be a clearly marked emergency off switch in an easily accessible position outside the boiler room, close to the boiler-room door. A hand-held fire extinguisher (6kg gross weight, EN3) must be mounted outside the boiler room near the boiler-room door. The boiler room, pipes carrying water and any district heating pipes must be protected against freezing. There mustbe no direct connection to rooms in which flammable gases or liquids are stored (e.g. garage).

1.3.2 Fuel storeroom requirementsThe same site requirements apply as for the boiler room. Due to the risk of injury when the system is in operation, storeroom doors must be lockable and kept locked. There must be a warning sign carrying the message "Do not enter when feeder system is running" attached to the storeroom door. If 50m of fuel or more can be stored, a manually operated fire extinguishing facility must be installed. It must be protected against freezing and connected to a pressurised water pipe (DN20 conduit). The discharge point must be located directly above where the fuel outfeed channel exits the storeroom. The fire extinguishing facility must be identified by a sign carrying the inscription "Fuel storeroom fire extinguisher". If the fuel storeroom is filled by a tanker truck using a compressed-air delivery system, the filler pipes must be earthed. With this method of filling, make sure the storeroom is dust-sealed. Electrical equipment is prohibited in the fuel storeroom. For storerooms in the services area, it is possible to dispense with F90 jacketing of the fuel store. The fuel must be stored separately (wooden boarding) from other materials and the fire containment zone must be less than 500m. If there is also a fire wall dividing off a living area, an automatic fire extinguishing facility is required. There must be a lockable F90-class inspection hatch above the fuel outfeed channel.
(See Section 2.7, "Fuel outfeed channel inspection hatch")
Fuel auger The drive motor and the necessary electrics must be installed outside the storeroom.
Structural requirements The enclosing walls must be capable of withstanding the possible static loads created by the fuel and when filling the fuel store. The following wall thicknesses have proven effective in practice:
Concrete, 10 cm, reinforced
Masonry/brick, 12 cm, plastered/rendered on both sides
Timber stud walling made with 12cm studs spaced at 62.5 cm, boarded on both sides with wooden materials 15-20 mm thick
Doors/boarding Above-ground fuel stores must be accessible by a door with a cross-sectional area of at least 1.80 m opening to the outside. The inside of the door opening must be covered with boarding so that the fuel cannot run out if the door is opened by mistake.
Damp-proofing The fuel must be protected against rain and contact with water or damp floors/walls. The storeroom must remain dry all year round. If there is a risk of temporarily damp walls, fitting a back-ventilated facing to the walls and lining them with wooden material may be required.

1.3.3 Flue requirementsThe flue must be matched to the system in order to ensure economical and trouble-free operation.
Important
The system must only be connected to the flue if the flue meets the legal requirements and the technical specifications. The flue must be matched to the boiler output and dimensioned in accordance with DIN 4705. In order to be able to accurately dimension the flue, the calculations must be based on the flue gas figures. When designing new flues, high thermal insulation chimneys (DIN 18160 T1 heat transmission resistance group I) or suitable fireclay flues that are insusceptible to damp and have general building regulation approval should be used. It is advisable to involve those responsible for approving the flue system early on in the planning phase.

2.4 Installing the automatic ash extraction system (H)The optional automatic ash extraction system is fitted as described in the separate installation instructions. They are supplied with the automatic ash extraction system.
2.5 Installing Powerchip, fuel agitator and outfeed (H)1.) Erect the boiler in the boiler room with the required wall
clearance as per Fig. 2/Section 2.3, setting the adjustable feet (Fig. 1) so that the boiler is tilted slightly upwards at the rear so that the air inside the boiler can escape when the system is filled.
2.) When erecting the boiler make sure that the fuel auger is fitted on the right of the boiler and can only be turned approx. 90 forwards or backwards (Fig. 3).
3.) The storeroom should not be significantly lower down than the boiler room. The maximum possible inclination angles for the outfeed auger are shown in Fig. 3. With the optional fuel chute extension (Fig. 4, Art. no. PH030-9-200-0) inclinations of up to 23 can be achieved. In such cases, the storeroom must be adapted to the slope of the agitator.
4.) With the stoker unit removed, insert the inlet seal (A, Fig. 9) between the stoker unit and boiler flange and secure with four M08x30 hexagon-head bolts, spring washers and nuts. Unscrew the foot (B, Fig. 9) on the stoker unit to take the weight of the stoker unit. Connect the electrical leads for the ignition fan, fill level switch, fire safety motor, stoker sensor, drive motor G1 and drive motor A1.
5.) Place the drive unit (C, Fig. 9) on the stoker unit and turn it towards the storeroom. The drive unit ball should form an airtight seal with the rubber seal (D, Fig. 9) of the stoker unit.
6.) Pre-assemble the required conveyor trough sections (0.22 m, 0.55 m, 1.10 m, 2.20 m or 2.97 m) on the floor. Always fit the 0.50 m trough section supplied (E, Fig. 9) in the area where the auger passes through the wall. Screw the individual trough sections firmly together using M08x30 hexagon-head bolts, washers and nuts (joins should be flush on the inside). Join the individual auger sections together so that the auger slope is even and continuous (F, Fig. 9). Then connect the pre-assembled outfeed auger to the drive unit (C, Fig. 9).
7.) Connect the agitator (G, Fig. 9) to the outfeed auger, making sure that the auger slope is even and continuous (F, Fig. 9). Then screw the auger trough sections firmly together.

8.) Fit the spring arms to the agitator. The agitator rotates clockwise (Fig. 5). Fit the longest arms opposite one another. The spring arms (I, Fig. 9) must be 15-20 mm above the outfeed auger at the point where they pass over it. Do not tighten the bolts (H, Fig. 9) on the springarms. The agitator feet (J, Fig. 9) must be adjusted so that the longest arm is 3-4 cm clear of the floor at its lowest point (K, Fig. 9).
9.) Screw the drive unit to the stoker unit using the fixing screws (L) (M10x100 and M10x140 mm) making sure it forms an airtight seal.
Always ensure the drive unit is fitted vertically (at 90 to the floor, see Fig. 6).
10.) Place the agitator centrally in the storeroom so that the spring arms clear the storeroom walls by a few centimetres. Firmly secure the agitator to the storeroom floor using masonry screws and wall plugs.
11.) Using the legs supplied, support the outfeed auger in the storeroom at the mid-point of the auger and where it exits the storeroom (Fig. 7) – the legs should not be more than 120 cm apart.
Position the feet so that they cannot move lengthways.The legs should rest against the flanges/support brackets of the auger. Place sound insulating material underneath to prevent noise transmission. Adjust the legs vertically so that the auger is resting firmly on them. Firmly secure the legs to the storeroom floor using masonry screws and wall plugs.
12.) Seal the hole in the wall (H, Fig. 9, dimensions H 700 x W 450 mm) around the outfeed auger with mineral wool and cover the gap on both sides of the wall with the cover plates supplied. If necessary, break out the perforations in the cover plates.
13.) Screw the galvanised mounting brackets supplied to the boiler base (Fig. 8) using the M8x16 hexagon-head bolts and slide the base insert and insulation (N, Fig. 9) under the boiler base.
14.) If the boiler is to be run on woodchips, a sloping storeroom floor is not absolutely imperative. If it is to run on grain or pellets, a sloping storeroom floor must be constructed.
Use planed timber boards (larch) or blockboard panels 3 cm thick
Rest the boards/panels on the lip of the outfeed auger. A supporting substructure as shown in Fig. 11 should be constructed at the rear of the agitator.
15.) The boarding (V, Fig. 7) over the inspection hatch must be provided on site and prevents uncontrolled spillage of the fuel into the boiler room. A sloping board 3 cm thick must be fitted at an angle of approx. 20, 20 cm above the outfeed auger, 20 cm from the storeroom wall and overlapping the inspection hatch opening by at

least 10 cm on each side 3. The structure must be adequately fixed and adequately supported underneath.
Important → The auger drive unit must form a 100% airtight seal with the fuel chute. The rubber seal must completely seal the ball joint. Fix the drive unit securely with the screws supplied.
16.) Because of the sprinkler system, the temperature monitor on the outfeed auger is not required for storerooms with a capacity of no more than 50 m. If the storeroom capacity is larger than 50 m, the temperature monitor as well as the sprinkler unit must be connected to the outfeed channel near to where it passes through the wall. If 50m of fuel or more can be stored, a manually operated fire extinguishing facility must be installed. It must be protected against freezing and connected to a pressurised water pipe (DN20 conduit). The discharge point must be located directly above where the fuel outfeed channel exits the storeroom. The fire extinguishing facility must be identified by a sign carrying the inscription "Fuel storeroom fire extinguisher".

2.8 Connecting the flue (H)
The boiler is connected to the flue by means of a flue connecting pipe which must be gas-tight and insulatedbetween the heating boiler and the flue (insulation thickness 50 mm).
Flue connecting pipe The following diameters should be used:
Powerchip 20/30 dia. = 150 mm
Powerchip 40/50 dia. = 150 mm
Powercorn 50 Special dia. = 180 mm
Powerchip 75 dia. = 180 mm
Powerchip 100 dia. = 180 mm
Flue connecting pipes longer than 4 m or with more than 3 bends:
Powerchip 20/30 dia. = 160 mm
Powerchip 40/50 dia. = 160 mm
Powercorn 50 Special dia. = 200 mm
Powerchip 75 dia. = 220 mm - 250 mm
Powerchip 100 dia. = 220 mm 250 mm
The hole in the wall for connecting the flue pipe must be lined with a built-in double-skinned lining tube or fireproof material. The flue connecting pipe must rise upwards from the boiler to the flue at an angle of at least 6 and be connected with gas-tight joints. An inspection cover must be provided for cleaning the flue connecting pipe.
A → Flue connecting pipe insulation (50 mm)
B → Testing point:distance from boiler3x flue tube diameter
C → Option of fitting in flue pipe forenergy saving draught regulator with pressure-surge compensator(observe local regulations)
D → Flue connecting pipe, min. gradient 6
E → Option of fitting in flue forenergy saving draught regulator with pressure-surge compensator(observe local regulations) Fig. 16
Flue caps and hoods Must be made of non-combustible materials and must not reduce the cross-sectional area of the flue, decrease the flue draught or obstruct the cleaning of the flue. The flue gas should be able to exit vertically from the flue outlet without hindrance. The method of fixing must be capable of withstanding strong gusts of wind.

2.9 Energy-saving flue draught regulator and pressure-surge compensator (F)
Purpose of the energy-saving flue draught regulator
To ventilate the flue when the system is not in operation
To compensate for pressure surges
To regulate and limit the flue draught
Fitting The energy-saving flue draught regulator must be fitted in accordance with the local regulations either in the flue approx. 0.5 m below the point where the flue connecting pipe joins or in the flue connecting pipe close to its junction with the flue.
Adjusting the flue draught regulator to the required flue draught
Adjusting the flue draught is only of any use at outside temperatures below +5C.
The system must have been in operation for at least an hour.
Ensure there is sufficient demand for heat for the boiler to be run at rated output for at least 15 minutes.
Measure the flue draught between the boiler and the flue draught regulator (distance of measuring point from boiler ideally 3 x flue diameter).
Flue draught The flue draught should not differ by more than +/- 3 pascals from the figure specified in the flue dimensioning data (see Section 1.3.3). If the flue draught cannot be reduced to the required figure, either a larger draught regulator should be fitted or an additional flue baffle fitted between the flue and the draught regulator.
Too much flue draught May cause the flue gas temperature to increase and accelerate combustion as a result. Poor boiler output adjustability, increased dust discharge and malfunctions can result.
Too little flue draught Performance problems, incomplete combustion and malfunctions when operating below rated output can result.
Fitting an energy-saving flue draught regulator/pressure-surge compensator
(Class RE) is absolutely imperative.

Return boost The boiler return temperature must be at least 55C and must be held at the required level by a bypass pump between the boiler flow and return pipes. If a thermal store is connected, the boiler return temperature must similarly be at least 55 C, which must be ensured by a return boost (cross-over valve) set as shown in the plumbing diagram. If this requirement is not complied with, there is an increased risk of corrosion and guarantee entitlement will be lost as a result. Connect the return boost set precisely as specified in our plumbing diagrams.
Important → The dimensioning of the return boost pump (set) is designed for the arrangements shown in GUNTAMATIC plumbing diagrams. If additional components such as heat meters are incorporated in the system plumbing, or if the overall thermal store pipe run (flow and return) is more than 30 m, re-dimensioning of the boiler charging pump (HP0) may be necessary.
Thermal store A thermal store is not absolutely essential as the boiler is operated by a modulating control system and the system can be quickly shut down. However, if the required continuous heat output in the summer months, and specifically in systems that incorporate a solar panel system, is below 10 kW for 30 kW systems, 15 kW for 50 kW systems or 22 kW for 75 or 100 kW systems, combination with a thermal store is necessary for reasons of efficiency.
Expansion vessel The boiler operates in a sealed heating system and must be provided with an expansion vessel for pressure compensation. To calculate the expansion volume, the volume of the system when cold must be known. Please select the expansion vessel on the basis of the manufacturer's specifications. The expansion volume of the system is calculated as follows:
System volume x Expansion factor x Additional allowance factor Expansion factor for wood-fuel boilers = 0.03
Additional allowance factor = 3.0 for systems under 30 kW Additional allowance factor = 2.0 for 30-150 kW systems Additional allowance factor = 1.5 for systems over 150 kW
Example calculation: 1500 litres x 0.03 x 3 = 135 litres
Plastic piping If plastic piping for underfloor heating or district heating pipes are connected, they must be protected against excessive temperatures by using a limiting thermostat for the circulation pumps.
Pump selection The choice of pump must be made by the installer or building technology planner on the basis of the friction data, the pipe cross-sectional area and the required delivery pressure for the piping system planned.

2.11 Filling and bleeding the system (H)The system is filled with water from the domestic supply. Please note the guidelines on "Corrosion and boiler protection in heating and domestic water systems".
Water quality The requirements are as follows:
Overall hardness→ < 1 fH
pH level → max. 8.3 - 9.0
Oxygen → < 0.1 mg/l
Water heater If a water heater is also used in addition to the GUNTAMATIC boiler, it should be filled according to the installation instructions for it.
Filling the system Proceed as follows when filling the system:
Match the pressure of the system when cold to the air charge pressure of the expansion vessel
Check the operating pressure on the pressure gauge
Bleeding the system Proceed as follows when bleeding the system:
Switch off and bleed circulation pumps.
Bleed boiler by opening the bleed valve in the boiler flow pipe and allowing air to escape until water runs out.
Bleed radiator heating system (if present) by opening the bleed valve on every radiator and allowing air to escape until water runs out.
Bleed underfloor heating system (if present) by opening each heating circuit and flushing through thoroughly until there are no more air bubbles in the heating circuit pipes.
Important: perform sequence in the correct order!
Start bleeding in the cellar or on the ground floor and finish in the attic.
Check the system operating pressure on the pressure gauge and add more water if necessary.
Restart circulation pumps.
Only systems that have been properly bled guarantee effective conveyance of heat.
