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 equipment
shutoff valve with 1/8" NPT tap is an accept-
able alternative to test gauge connection.
CONNECTING TO GAS
SUPPLY
WARNING A qualified service
person must connect heater to
gas supply. Follow all local codes.
INSTALLATION
Continued
WARNING: Never connect
heater to private (non-utility) gas
wells. This gas is commonly
known as well-head 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 of 1/2"
diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur.
Continued
Installation must include an 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: Avoid damage to
gas control. Hold gas control with
wrench when connecting it to gas
piping and/or fittings.
* Minimum inlet pressure for purpose of input adjustment.

CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
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.

WARNING: This appliance re-
quires a 1/2" NPT (National Pipe
Thread) inlet connection to the
pressure regulator.
We recommend that you install a 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
sediment trap where trapped matter is not
likely to freeze. A sediment trap traps mois-
ture 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.
