input adjustment.

CONNECTING TO GAS
SUPPLY

 WARNING: A qualified ser-

vice person must connect heater
to gas supply. Follow all local
codes.

Installation Items Needed

Before installing heater, make sure you have
the items listed below.

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• manual shutoff valve *

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

*  An A.G.A. design-certified manual shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-
chase the optional A.G.A. design-certified
manual shutoff valve from your dealer. See
Accessories, page 25.

 CAUTION: Use only new,

black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of 1/2"
diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur.

Installation must include a manual shutoff
valve, union, and plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from
heater (see Figure 13).

Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged heater valves.

 CAUTION: Use pipe joint seal-

ant that is resistant to liquid pe-
troleum (LP) gas.

Install sediment trap in supply line as shown
in Figure 13. Locate sediment trap where it
is within reach for cleaning. Locate sedi-
ment trap where trapped matter is not likely
to freeze. A sediment trap traps moisture
and contaminants. This keeps them from
going into heater controls. If sediment trap
is not installed or is installed wrong, heater
may not run properly.

 WARNING: Never connect

heater to private (non-utility) gas
wells. This gas is commonly
known as well-head gas.
