3. VENTING
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
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 CLOSE TO
THE DRAFT HOOD RELIEF OPENING.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. To inspect draft from the front of the unit, Remove top
louvers by pulling up and out. Locate the 3/8” tube between the heat exchanger and top, check for a draft using smoke. A
vacuum or suction into the tube will indicate proper drafting.
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.
