INSTALLATION ITEMS

• piping (check local codes)
• sealant (resistant to propane gas)
• manual shutoff valve *
• ground joint union
* An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an acceptable

manual shutoff valve from your dealer. See Accessory, page 26.
LOCATING HEATER
This heater is designed to be mounted on a wall.
Maintain the minimum clearances shown in Figure 4 (page 10). If
you can, provide greater clearances from floor, ceiling, and
joining wall.
Never install the heater
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture, clothing, or other flammable objects are
less than 36 inches from the front, top, or sides of the heater
• as a fireplace insert
• in high traffic areas
• in windy or drafty areas
This heater creates warm air currents. These currents move heat
to wall surfaces next to heater. Installing heater next to vinyl or
cloth wall coverings or operating heater where impurities in the air
(such as tobacco smoke) exist, may discolor walls.
IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, in-
stalling heater in rooms without enough ventilation air may cause mildew to form from
too much moisture. See Fresh Air for Combustion and Ventilation, pages 5 through 8.
If you install the heater in a home garage
• heater pilot and burner must be at least 18 inches above floor
• locate heater where moving vehicle will not hit it
NOTICE
• test gauge connection * (see
Figure 12, page 14)
