Supply/return bypass for large water content systems
For boilers connected to large water content systems (typically systems withvolume > 1 USG / 3.8 ltr for every 13000 Btu/h of boiler input), such as a previousgravity system with large free-standing radiators, a bypass line from the supply pipeto the return pipe must be used to avoid flue gas condensation in the heatexchanger and the vent system. A bypass can be installed on any system as apreventative measure. Viessmann strongly recommends installing a bypass pipe onall cast iron boilers.

Mechanical Room
During the early stages of new home design, we recommend that properconsideration be given to constructing a separate mechanical room dedicated to gasor oil fired equipment including domestic hot water storage tanks.
The boiler must be located in a heated indoor space, near a floor drain, and as closeas possible to the vertical chimney or vent.
Install the boiler on a concrete foundation if:- the floor may be flooded,- the floor is not level,- the boiler will be installed in a residential garage (in this case ensure that theburner is raised at least 18” / 457 mm above the floor to avoid contact withflammable vapors and fumes).
Viessmann strongly recommends installing the boiler on a concrete foundation.
Whenever possible install boiler near an outside wall so that it is easy to duct freshair directly to the boiler area. In addition, do not use exhaust fans in the boiler roomand do not install the boiler in rooms with refrigeration equipment. This equipmentrequires uncontaminated outside air for safe operation - do not install wherechemicals are stored or in a room with negative pressure. See section entitled“Combustion Air Supply” for further details regarding the above.
Locate boiler on flooring capable of supporting the weight of the boiler filled withwater. Ensure that the boiler location does not interfere with the proper circulationof combustion and ventilation air within the mechanical room.

Always use latest editions of codes.
GeneralThis equipment requires fresh air forsafe operation and must be installedensuring provisions for adequatecombustion and ventilation air exist.
Whenever possible, install boiler near anoutside wall so that it is easy to ductfresh air directly to the boiler area.
The boiler location must never be undernegative pressure. Exhaust fans, atticfans, or dryer fans may cause air to beexhausted at a rate higher than air canenter the structure for safe combustion.
The heating contractor shall ensure allof the following requirements are met:HAn adequate supply of combustion airmust be available to ensure propercombustion.
HAmbient air temperatures must bemaintained within safe operatinglimits.
HWhen a damper is provided in anyopening intended to admit combustionair into the room within which theappliance is installed, the damper shallbe interlocked to prevent any burnerfrom starting before the damper isfully open.
H Each duct used to convey air from theoutdoors shall have:1. A cross-sectional area throughout
its length at least equal to the freearea of the inlet and outletopenings which it connects,
2. A minimum dimension of3” / 76 mm at any cross-section,
3. When making provision for outsidecombustion air, the intake shall notbe less than 1 ft / 0.3 m above theanticipated snow level for thelocation.

Initial Start-Up
Burner instructions.
1. Ensure fresh air intake of boiler roomis open and that chimney and all fluepipes are connected, sealed andunobstructed inside.
2. Ensure proper size and operation ofexpansion tank. Undersized expansiontanks cause fresh water to be addedto the system through fill valve. Thiswill cause premature section failure,which is not covered by warranties.
3. Fill heating system with water andbleed out air completely. Ensurecomplete system is properly ventedof air.
4. Perform a pressure test of the boilerand the water piping. Pressure testmust not exceed 1½ times themaximum operating pressure (45 psi)of the boiler. Pressure relief valvemust be removed during pressuretest. Any leaks must be corrected.
H the max. operating pressure is45 psig / 310 kPa
H the max. testing pressure is68 psig / 465 kPa.
5. Ensure proper and adequate fuelsupply exists; open oil shut-off valve.
If the nitrogen pressure of theprecharged expansion tank is lessthan the static pressure of thesystem, inflate membrane pressure toslightly exceed pressure of system.The static pressure required at thetank is based upon the static heightof the system. Normal fill pressure formost residential applications is 12 to15 psig when the system is cold. Alower pressure gage reading usuallyindicates loss of water due toleakage. All leaks must be corrected.Refer to instructions packaged withautomatic fill valve. Follow localregulations with respect to backflowpreventers.
Water treatment should be consideredin areas where it is known that boilerfeed water contains a high mineralcontent and hardness. Contact localwater treatment company.
In areas where freezing might occur,an antifreeze may be added to thesystem water to protect the system.Please adhere to the specificationsgiven by the antifreeze manufacturer.Do not use automotive silicate-basedantifreeze. Ensure a copy of theMaterial Safety Data Sheet is left onsite.Please observe that anantifreeze/water mixture may requirea backflow preventer within theautomatic water feed and influencecomponents such as diaphragmexpansion tanks, radiation, etc. A40% antifreeze content will providefreeze-up protection to -10°F / -23°C.Do not use antifreeze other thanspecifically made for hot waterheating systems. System also maycontain components which might benegatively affected by antifreeze.Check total system frequently whenfilled with antifreeze. Followanti-freeze manufacturer’sinstructions. 5

Combustion analysisThis oil burner requires combustionmeasurements performed at the finalinstallation site, using calibratedcombustion equipment, to verify factorysettings, or to be used as a guide inchanging burner settings to suite localconditions.
Examples of local conditions whichinfluence combustion results include:weather conditions, length of horizontalvent pipe, diameter and height of thechimney, side wall venting (powervent), altitude above sea level, qualityand heating value of oil used, maximumnumber of other fuel burning appliancesrunning at the same time. Theseconditions affect the burner set-up. Theburner must be adjusted for acceptablecombustion results under localconditions of the installation.
Combustion measurements (CO2, stacktemperature, draft and CO) are taken inthe flue pipe between boiler andbarometric draft regulator beforedilution air (see the installation manual).Overfire draft is measured at thecombustion chamber observation portopening. The expected CO2 averagerange for #2-oil is from 11.0% to13.0%.

8. Ensure proper operation of expansion tank, low water cut-off (if applicable) and pumps
Refer to maintenance instructionssupplied with diaphragm expansiontanks, low water cut-offs, pumps, etc.
Flush float water type low watercut-offs (if used).
The usual water fill pressure is between10 and 15 psi with the system cold. Alower pressure gage reading usuallyindicates loss of water due to leakage.All leaks must be corrected. Refer toinstructions packaged with automaticfill valve. Follow local regulations withrespect to backflow preventers.
If oil-lubricated pumps are used, ensureproper lubrication.
If motorized zone valves are used, referto maintenance instructions providedwith zone valves.
If an older non-diaphragm expansiontank is used, ensure the correct waterlevel is present.
9. Ensure that an adequate combustion air supply exists in the boiler room
Ensure fresh air intake of boiler room isopen. This opening must never beblocked or partially covered.
10. Ensure functionality of the barometric draft regulator of the burner
During operation of the burner, thebarometric draft regulator installed inthe vent system must move freely.

Instructions suppliedwith Beckett burner
Combustion analysisThis oil burner requires combustionmeasurements performed at the finalinstallation site, using calibratedcombustion equipment, to verify factorysettings, or to be used as a guide inchanging burner settings to suite localconditions.
Examples of local conditions whichinfluence combustion results include:weather conditions, length of horizontalvent pipe, diameter and height of thechimney, side wall venting (powervent), altitude above sea level, qualityand heating value of oil used, maximumnumber of other fuel burning appliancesrunning at the same time. Theseconditions affect the burner set-up. Theburner must be adjusted for acceptablecombustion results under localconditions of the installation.
Combustion measurements (CO2, stacktemperature, draft and CO) are taken inthe flue pipe between boiler andbarometric draft regulator beforedilution air (see the installation manual).Overfire draft is measured at thecombustion chamber observation portopening. The expected CO2 averagerange for #2-oil is from 11.0% to13.0%.
