BRT40ST See-Through B-Vent Gas Fireplaces
WARNING
Do not operate the shutoff lever
unless a complete outside com-
bustion air system has been
installed with your appliance.
To open the outside air shutter, open the bottom
control access panel, reach into the gap between
the firebox bottom and the modesty panel, and
pull the outside air control lever all the way out.
The outside air shutter should be fully open when
the fireplace is in use and completely closed
when the fireplace is not being used. Closing
it when not in use will prevent outside cold air
from entering the dwelling.
Venting Action and Safety Limit Operation
If you suspect that the appliance is not vent-
ing properly, or you notice windows fogging
or sweating, you may want to conduct the
following spillage test:
1 - Place unit in its normally-operated condi-
tion, that is, with the glass enclosure panels
in place.
2 - Close all doors and windows in the room.
Turn on all exhaust fans in the house.
3 - Light the appliance.
4 - Wait 15 minutes.
5 - To check for venting action, start by holding
a smoke producing device within an inch
of one edge (side edge, not top or bottom
edge) of one glass enclosure panel. The
smoke should be drawn toward the edge
of the glass enclosure panel. Continue the
test by moving the smoke producing device
along the entire length of both side-edges of
the glass door. Repeat the test for all glass
enclosure panels.
6 - If the smoke is not drawn towards the edges
of the glass door turn off the appliance
and call a qualified service technican.
Manual-Reset Safety Limit Switch
This appliance is equipped with a manual-reset
blocked flue safety limit switch. Refer to Figure
37 for its location. If, during appliance opera-
tion, the flame goes out (independently of the
burner on/off wall switch), it may be due to the
operation of this safety limit switch. First allow
the appliance to cool, then reset the safety
switch by pushing the red reset button on it.
A - To access the blocked flue safety switch:
1 - Remove the hood by pulling straight out
from the unit. Remove the front face as-
sembly by pulling up approximately 1/2"
and away from unit3.
2 - Reach between the cabinet side and the
firebox side wall and locate the blocked
flue safety switch.
3 - Push the red reset button on the switch.
The appliance should then relight and remain
lit. If this does not occur, turn off the appliance
and call a qualified service technician.
