Warning: Only persons licensed to work with gas piping may make the necessary gas connections to
this appliance.
Gas Line Connection:
•This fireplace is equipped with a certified flexible pipe located on the right side of the unit, terminating
in a 3⁄8” male NPT fitting. Consult the local authorities for local codes or use the CAN/CGA B149 (1 or 2)
installation code in Canada. In the US, gas installations follow either local codes or the current edition of
the National Fuel Gas Code ANSI Z223.1.
•The efficiency of this unit is a product thermal efficiency rating determined under continuous operating
conditions and was determined independently of any installed system.
The appliance and its’ shut-off valves must
be disconnected from the gas supply piping
system during any pressure testing where
the pressure exceeds 1⁄2 psig (3.45 KPa) or
the valve will be damaged.
The unit 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 pressures equal to or less than
1⁄2 psig (3.45 KPa).
Always check for gas leaks with a soap
and water solution after completing
the required pressure test.

TO TEST VALVE PRESSURES:
The pressure taps are located on the top right of
the valve.
• Turn set screw 1 turn counterclockwise to
loosen.
• Place 5/16 in (8 mm) I.D. hose over the
pressure taps.
• Check pressures using a manometer.
• When finished, release pressure, remove hose
and tighten set screw.
NEVER USE AN OPEN FLAME FOR LEAK TESTING.
