WARNING:
Only persons licensed to work with gas piping
may make the necessary gas connections to this
appliance.
Gas Line Connection:
• A ⅜” 45° flare and flex connector are supplied with the
unit (see Figures 25 and 26). 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.
• 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.
