B-VENT MODEL:

WARNING: This appliance has been designed to operate by drawing combustion air and dilution air from the room. It is also designed to draw room air for proper heat circulation from the sides of the unit. Blocking or modifying the louvers in any way can create hazardous situations, either through poor venting or by overheating. It is important that this unit has sufficient air circulation for proper venting and combustion. Provisions must be made for the supply of adequate combustion and ventilation air. These openings must not be blocked. The appliance must not be connected to a chimney flue servicing a separate solid fuel-burning appliance.

AUTOMATIC FLUE GAS SPILL SWITCH - B-VENT MODEL ONLY:

NOTE: This heater must be properly connected to a venting system. This heater is equipped with a vent safety shutoff system designed to protect against improper venting of combustion products. This safety switch is located on the rear of the appliance. If the switch trips more than once, the venting should be inspected by a qualified service technician for possible blockage or severe down draft conditions.

The draft hood must be in the same pressure zone as the air inlet. Inspect for draft from the front of the unit at the 1⁄4” tube shown in Figure 10. Check for a draft using smoke; a vacuum or suction into the tube will indicate proper drafting. If air is blowing out of the tube the problem must be corrected before the unit can be started.

This model can be vented with 4” aluminum or stainless steel flex vent and/or certified Type B Gas Vent. The flue collar of the appliance will fit inside of a standard 4” vent and may be fastened directly to the vent. Check periodically that the vent is unrestricted and an adequate draft is present when the unit is in operation.

Check draft with a match

or smoke in a 1⁄4" (6 mm)

tube located here.
