Warning: Only persons licensed to work with gas piping may
make the necessary gas connections to this appliance.
Gas Line Connection:
• A ⅜” NPT male pipe nipple (supplied with the unit) will
have to be turned into the valve at the lower left side rear
of this fireplace (see Figures 33 and 34). 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.
• If the factory-built fireplace has no gas access hole(s)
provided, an access hole of 1.5 in (37.5mm) or less may be
drilled through the lower sides or bottom of the firebox in a
proper workmanship like manner. This access hole must be
plugged with non-combustible insulation after the gas supply
line has been installed.”
•
A shut-off valve is not supplied with this unit but one should
be installed.
• The appliance and its shut-off valves must be disconnected
from the gas supply piping system during any pressure testing
where the pressure exceeds ½ 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 ½ psig (3.45 KPa).
