Insulated Vent Enclosure
Gravity vented wall furnaces installed in buildings with ß at 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 ß ue 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 ß ow of dust and 
lint particles into the main burner.  
Dust and lint accumulation inside the main burner will result in a yellow 
main burner ß ame and possible sooting inside the combustion chamber 
and vent pipe.  To clean main burner refer to Page 13, "Proper Main Burner 
Flame."
