WARNING: Only persons licensed to work with gas piping
may make the necessary gas connections to this appliance.
Gas Line Connection:
• A ⅜” 45° flared fitting and flex connector are supplied with
the unit (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.
• 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 supplied with this unit.
• The appliance and its main gas valve must be disconnected
from the gas supply piping system during any pressure
testing of that system at test pressures in excess ½ psi (3.5
kPa). The appliance must be isolated from the gas supply
piping system by closing its equipment shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psi (3.5 kPa).
