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 combustion chamber and vent pipe To clean main burner refer to Page 13 Proper Main Burner Flame Page 6 12425 7 0406 GAS SUPPLY Check all local codes for requirements especially for the size and type of gas supply line required Recomme
