certified equipment shutoff valve from your
dealer. See Accessories, page 30.
** Minimum inlet pressure for purpose of

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)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* An CSA/AGA design-certified equip-
ment shutoff valve with 1/8" NPT tap is an
acceptable alternative to test gauge connec-
tion. Purchase the optional CSA/AGA de-
sign-certified equipment shutoff valve from
your dealer. See Accessories, page 30.
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 equipment 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).
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
We recommend that you install sediment
trap in supply line as shown in Figure 13.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and heater. 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.

IMPORTANT: Install 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.
WARNING: This appliance
requires a 1/2" NPT (National Pipe
Thread) inlet connection to the
pressure regulator.
