VENTILATION
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.
*Tank size and tank temperature can directly affect BTU output

WARNING
Combustion by-products produced when using this product contain
carbon monoxide, a chemical known to the State of California to
cause cancer and birth defects (or other reproductive harm).
