AIR FOR COMBUSTION
AND VENTILATION
Continued
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining un- confined space. When ventilating to an adjoining unconfined space, you must provide two perma- nent openings: one within 12" (30.4 cm) of the ceiling and one within 12" (30.4 cm) of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent open- ings: one within 12" (30.4 cm) of the ceiling and one within 12" (30.4 cm) of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat- controlled power vent. Heated air entering the attic will activate the power vent.
WARNING: A qualified ser- vice person must install heater. Follow all local codes.
CHECK GAS TYPE
Use only the correct type of gas (natural or pro- pane/LP). If your gas supply is not the correct gas type, do not install heater. Call dealer where you bought heater for proper type heater.
WARNING: This appliance is equipped for (natural or pro- pane/LP) gas. Field conversion is not permitted.
