Figure 27 - Gas Valve
Do not do a gas conversion on this boiler without an officially
approved conversion kit and instructions supplied by HTP.
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.
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.
C. Boiler Gas Valve
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.
