Do not locate heater where expelled exhaust gases can be
recirculated into heated space. Exhaust gases contain car-
bon monoxide, a colorless, odorless, deadly poisonous gas.
Failure to provide proper elimination of the exhaust can
cause severe illness or death.
Position heater so that exhaust can be vented to outside with short, direct run. Fresh air is
normally pulled in through side louvers.
If louvers are obstructed or a greater air flow is required, remove screws (1) and lock washers (2)
and lift off bottom cover (3).
Package screws and lock washers and tape or otherwise secure to bottom cover. Identify bottom
cover and retain. Bottom cover (3) must be reinstalled when heater is prepared for shipment or
storage.
If louvers are not needed as air inlets, install side covers (4). Remove screws (5) and lock
washers (6) from side panels (7) and use to install side covers.
