Figure 13 - Gas Connection
* A 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 16.

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.
IMPORTANT:
Hold pressure regulator with
wrench when connecting it to gas piping
and/or fittings.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
Installation must include 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 up-
stream from heater (see Figure 13).
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.
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.
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incoming gas pressure between 11 and 14
inches of water. If you do not reduce incom-
ing gas pressure, heater regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
12. Pointing the vent down protects it from
freezing rain or sleet.
WARNING: Never connect
heater directly to the propane/LP
supply. This heater requires an
external regulator (not supplied).
Install the external regulator be-
tween the heater and propane/LP
supply.
WARNING: A qualified service
person must connect heater to
gas supply. Follow all local codes.

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 3/8" NPT (National Pipe
Thread) inlet connection to the
pressure regulator.
