RECOMMENDED VENT CONFIGURATION

37410-6-0620
NOTICE: No vent equipment supplied with furnace.
4" Oval (all parts purchase locally)
1. Type B-1 oval pipe
2. Single story type B-1 gas vents require a baseplate and one
pair of ceiling plate spacers.
3. Multi-story type B-1 gas vents require a baseplate, one pair
of ceiling plate spacers at the first floor ceiling and one pair of
fire stop spacers at each successive ceiling level.
Type B-W gas vent pipe is available for single story or
multi-story installations. Type B-W gas vent pipe is to
be used with the Listed base plate, ceiling plate spacers
and fire stop spacers.
Insulated Vent Enclosure
Gravity vented wall furnaces installed in buildings with flat roofs can
have poor venting. The cold vent pipe will have a delay in proper
venting and cause the wall furnace to shut "off" by the vent safety
switch. To prevent delayed venting as well as condensation of flue
products an insulated vent enclosure is recommended.
Use Type B vent pipe and maintain at least a one inch (25mm)
clearance to combustibles.
Use metal thimble to protect vent pipe as it passes through
combustibles.
Baseplate Gasket is factory installed on header. Baseplate attaches
to header with screws. B-vent snaps into and is attached to baseplate.
Minimum height of vent pipe must be six feet (1.8m) above header.
Stud space around gas vents must be free of obstructions and
building paper.
Uninsulated Single-Wall Metal Pipe shall not be used outdoors in
cold climates for venting gas utilization equipment.
Attention: The main burner uses room air for combustion. As the
gas/air mixture is injected into the main burner, there is also the
flow of dust and lint particles into the main burner.
Dust and lint accumulation inside the main burner will result in a
yellow main burner flame and possible sooting inside the combus-
tion chamber and vent pipe. To clean main burner refer to Page 14,
"Proper Main Burner Flame."
