• Install boiler so that gas ignition system components are
protected from water (dripping, spraying,rain, etc.) during
appliance operation and service (circulator replacement,
condensate trap, control replacement, etc.).
• Gas meter and supply pipes must be capable of delivering
the listed quantity of gas in addition to demand from any
other appliances in the house. Boiler requires a minimum
3/4” (19.5 mm) gas supply pipe.
• Support piping with hooks straps, bands, brackets,
hangers, or building structure components to prevent or
dampen excessive vibrations and prevent strain on gas
connection. Boiler will not support piping weight.
• Use thread (joint) compound (pipe dope) suitable for
liquefied petroleum gas.
• Leak test boiler and gas line connections before placing
boiler into operation.
•
Install external field sourced manual main gas shutoff
valve, ground joint union, and sediment trap upstream
of gas controls. in accordance with state and local
requirements.
•
Size and install gas piping system to provide sufficient gas
supply to meet maximum input at not less than minimum
supply pressure.
• Boiler shall be isolated from the gas supply piping system
by closing its individual manual shutoff valve during
any pressure testing of gas supply piping system at test
pressures equal to or less than 1/2 psi (3.40 kPa - 34.47
mbar).
