Superior BRT4036TMN Installation And Operation Instructions Manual page 11

Some codes areas allow the use of existing
B-type vent systems if the system is at or
above the recommended diameter of the flue,
in this case 6".
The flue connection must be made using
listed B-type connectors and the existing
system must be code inspected for damage
and proper installation.
It is not recommended that this appliance be
common vented with an existing gas burning
appliance.
Note: Before connecting this appliance to an
existing vent system consult with your local
architect, planner 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 the lighting
instructions and allow main burner to run
for approximately 5 minutes. Hold a lighted
match or cigarette near the top edge of fire-
place opening and play it along entire length
of 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 appliance is found to be improperly vent-
ing, shut it off and notify your installer or a
qualified service agency to inspect the vent-
ing 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.
Check this area
along entire top
edge of fireplace
opening. Smoke
or flame should be
drawn into appliance
opening.
