Installation
Connect Gas Supply
It is preferable to rough-in the gas line at this point
before proceeding with the firebox installation.
The gas supply inlet connection is a 3/8" NPT female
connector. For detailed location of this connector, see
drawing in Dimensions on page 11 or page 16. If a
circulating fan or isolating valve is to be installed, adjust
the routing of the gas line to suit.
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 sufficient 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-off 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-off 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-off
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.
Connect Gas Supply
When testing for leaks:
• Make sure that the appliance is turned off .
• Open the manual shut-off valve.
• Test for leaks by applying a liquid detergent or soap
solution to all joints. Bubbles forming indicate a gas
leak.
WARNING
NEVER USE OPEN FLAME to check for leaks.
Correct any leak detected immediately.
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.
See Appendix A – Lighting Instructions Plate on page 42

Connect Gas Line and Test Appliance
Connect the gas line to the burner module. Check for
leaks, purge the line, and test-fire the unit before
installing the window or proceeding with the remainder
of the installation—see Appendix A – Lighting Instructions
Plate on page 42.
