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 these openings 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.
A vent connector of Type B vent material must be installed with a minimum clearance of 1” (25mm)
to combustible material, including passage through either a combustible wall or partition and must be
securely assembled in accordance with the manufacturer’s certified instructions.
A vent connector must be install with neither dips nor sags and must be securely supported by non-
combustible hangers suitable for the weight and design of the materials employed. A slip joint in the
horizontal section of a vent connector must be secured with either sheet metal screws, or other approved
means to prevent sagging.

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 30). Note that when the door is installed the tube is not visible
when looking straight at the unit. 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 3”
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 3” 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.
