Figure 12 - Gas Connection
* An CSA/AGA design-certified equipment shutoff valve with 1/8" NPT tap is an
acceptable alternative to test gauge connection. Purchase the optional CSA/AGA design-
certified equipment shutoff valve from your dealer. See Accessory, page 18.

Installation must include an equipment
shutoff valve, ground joint 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 12).
IMPORTANT:
Install an equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.
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.
Install sediment trap in supply line as shown
in Figure 12. 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.
IMPORTANT:
Hold pressure regulator
with wrench when connecting it to gas pip-
ing and/or fittings.
IMPORTANT:
Check gas line pressure
before connecting heater to gas line. Gas
line pressure must be no greater than 14
inches of water. If gas line pressure is higher,
heater regulator damage could occur.
WARNING: A qualified service
person must connect heater to
gas supply. Follow all local codes.
WARNING: Never connect
heater to private (non-utility) gas
wells. This gas is commonly
known as wellhead gas.
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 3/8"
diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
