the items listed below:
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• manual shutoff valve *
• ground joint union
• test gauge connection * (see Figure

• sediment trap
• tee joint
• pipe wrench
NOTICE: A qualified service per-
son must install heater. Follow
all local codes.
* An A.G.A. design-certified manual shutoff

chase the optional A.G.A. design-certified

LOCATING HEATER
This heater is designed to be mounted on a
wall.
WARNING: Maintain the mini-
mum clearances shown in Figure
4. If you can, provide greater clear-
ances from floor, ceiling, and join-
ing wall.
CAUTION: 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 ve-
hicle will not hit it
IMPORTANT: Vent-free heaters add mois-
ture to the air. Although this is beneficial,
installing heater in rooms without enough
ventilation air may cause mildew to form
from too much moisture. See Fresh Air for
Combustion and Ventilation, pages 3 through
5.
CAUTION: This heater cre-
ates warm air currents. These
currents move heat to wall sur-
faces 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.
WARNING: Never install the
heater
• in a bathroom (Model CGN10A
- Input 10,000 Btu’s)
• 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
