NOTICE
Use of CSA approved corrugated, semi-rigid stainless
steel tubing with polyethylene jacketing is approved
for use with boilers following tubing manufacturer's
instructions.
Use of flexible
"appliance whip"
gas tubing is not
allowed per NFPA 54.
WARNING
Fire, explosion, asphyxiation and burn hazard. Boiler
piping and gas connections shall be leak tested before
placing boiler in operation. Failure to follow these
instructions and or improper installation could result in
death or serious injury.

WARNING
If overheating occurs or gas supply fails to shut off, do
not turn off or disconnect the electrical supply to the
pump. Shut off gas supply at a location external to the
appliance.
Do not use this boiler if any part has been under
water. Call a qualified service technician before use.

7 - GAS SUPPLY PIPING
NOTICE
If overheating occurs or gas supply fails to shut off, do
not turn off or disconnect electrical supply to pump.
Shut off gas supply at location external to the boiler.
•
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 (3.5 kPa).
• 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 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.
•
Install external field sourced manual main gas shutoff
valve, ground joint union, and sediment trap upstream of
gas controls. See Figure 7-1.
•
Leak test boiler and gas line connections before placing
boiler into operation.
7.1 General
•
Use piping materials and joining methods acceptable
to authority having jurisdiction. In absence of such
requirements:
•
USA - National Fuel Gas Code, ANSI Z223.1/NFPA 54
•
Install manual main shutoff valve before the gas valve
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 and its individual shutoff valve shall be disconnected
from gas supply piping system during any pressure testing
of that system at test pressures in excess of 1/2 psi (3.40
kPa - 34.47 mbar).
