Boiler Gas Valve - Westinghouse WBMC**500 Manual

D. Boiler Gas Valve
Figure 29 - 500 Gas Valve
Figure 30 - 850 Gas Valve
Do not do a gas conversion on this boiler
without an officially approved conversion kit
and instructions supplied by Westinghouse.
Failure to use a conversion kit when
converting the boiler to fire on Natural
or Propane gas will result in extremely
dangerous burner operation, leading to fire,
explosion, severe personal injury, or death.
Strain on the gas valve and fittings may result
in vibration, premature component failure
and gas leakage, and result in fire, explosion,
property damage, severe personal injury, or
death.
Adjustments to the throttle screw or
offset may only be made by a qualified gas
technician using a calibrated combustion
analyzer capable of measuring CO2 and CO.
Failure to follow this instruction could result
in fire, explosion, property damage, severe
personal injury, or death.
Ensure that the high gas pressure regulator is
as least 6 – 10 feet upstream of the appliance.
Failure to do so could result in substantial
property damage, severe personal injury, or
death.
