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.

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.
WARNING: Operation of this heater when not connected to a properly installed and maintained
venting system can result in carbon monoxide (CO) poisoning and possible death.
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 18. 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
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.
