WARNING
THIS APPLIANCE IS UNVENTED AND MUST BE
USED ONLY IN A WELL VENTILATED AREA.
The flow of combustion and ventilation air must not be
obstructed. DO NOT use in a tightly enclosed area.
Any combustion process requires and consumes oxygen, and may
produce carbon monoxide. This heater must be operated with
adequate ventilation. Two openings directly to the outdoors must
be provided, one low and one high, preferably on opposite sides
of the area to be heated. Each of these openings must provide
at least three square inches of combustion air-intake area and
exhaust outlet area for every 1000 BTUs per hour of heater input
rate in order to complete the combustion/ventilation process.
Provide additional ventilation for any additional fuel-burning
appliances and/or additional occupants.
