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.
