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.
Do not exceed the gas supply pressures shown on rating plate
for Model MH18CH. The maximum inlet gas supply pressure and
the minimum inlet gas supply pressure (for purposes of input
adjustment) for LP-Gas are shown as follows:
*Tank size and tank temperature can directly affect BTU output
