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.

CLEARANCE (Minimum clearances to combustible materials)

Do not exceed the gas supply pressures shown on rating plates. The maximum inlet gas supply pressures and minimum inlet supply pressures (for purposes of input adjustment) for LP-Gas and Natural gas are shown as follows:
