Connect Gas Supply
It is preferable to rough-in the gas line at this point
before proceeding with the
fi
rebox installation.
The appliance is supplied for supply gas connection at
the control valve. Supply line connection to the control
valve os the appliance is 3/8” NPT female. Take care not
to apply torque to the valve. An isolation valve may be
fi
tted within the appliance case. Be aware that the
supply pipe should follow routing to clear the remote
receiver or optional fan.
Use only new black iron or steel pipes, CSST, or copper
tubing if acceptable—check local codes.
Note that in
USA, copper tubing must be internally tinned for
protection against sulfur compounds.
Union in gas lines should be of ground joint type.
The gas supply line must be sized and installed to
provide a supply of gas su
ffi
cient to meet the maximum
demand of the appliance without undue loss of
pressure.
Sealant used must be resistant to the action of all gas
constituents including propane gas. Sealant should be
applied lightly to male threads to ensure excess sealant
does not enter gas lines.
The supply line should include a manual shut-o
ff
valve
and union to allow the appliance to be disconnected for
servicing.
Pressure test the supply line for leaks.
The appliance and its individual shut-o
ff
valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.5kPa).
The appliance must be isolated from the gas supply
piping system by closing its individual manual shut-o
ff
valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than
1/2 psig (3.5kPa).
Failure to either disconnect or isolate the appliance
during pressure testing may result in regulator or valve
damage. Consult your dealer in this case.
The minimum supply pressure is given on page 6 of this
manual.
All piping and connections must be tested for leaks
after installation or servicing. All leaks must be
corrected immediately.
When testing for leaks:
• Make sure that the appliance is turned o
ff
.
• Open the manual shut-o
ff
valve.
• Test for leaks by applying a liquid detergent or soap
solution to all joints. Bubbles forming indicate a gas
leak.
The pressure test tapping locations are shown below. A
built-in non-adjustable regulator controls the burner
manifold pressure. The correct pressure range is shown
page 6 of this manual. The pressure check should be
made with the burner alight and at its highest setting.

Appendix A – Lighting Instructions Plate
page 42 for
