VeNtING INstAllAtIoN
Continued
It is not recommended that this appliance be
common vented with an existing gas burning
appliance. However, if it becomes necessary
to common vent this appliance, the venting
system must be sized and configured in ac-
cordance with the common venting guides
Appendix G of the current National Fuel Gas
Code NFPA No. 54/ANSI Z223.1.
Note: Before connecting this appliance to an
existing vent system or a common venting
system consult with your local architect, plan-
ner, or building official.
WARNING: This appliance
must be properly connected
to a system and must not be
connected to a chimney flue
servicing a separate solid fuel
burning appliance.
CHECKING FOR PROPER VENTING
After completing and checking electrical,
gas and vent connections, follow lighting
instructions and allow main burner to run
for approximately 5 minutes. Hold a lighted
match or cigarette near top edge of fireplace
opening and play it along entire length of
the opening (see Figure 12). Proper venting
should tend to draw the flame or smoke into
the appliance. Improper venting or escaping
of spillage of burned gas, is indicated when
the match flickers or goes out. Smoke from a
cigarette will also tend to disperse away from
the appliance.
If the appliance is found to be improperly
venting, shut it off and notify your installer
or a qualified service agency to inspect the
venting system.
NOTICE: This appliance is
equipped with a vent safety
shutoff switch which will shut
down the appliance in the case
of a venting problem. Do not
bypass the vent safety switch. If
the appliance should shut down,
contact a qualified installer, ser-
vice agency or your gas supplier
to have the vent inspected before
operating.
