WARNING: A qualified
service person must connect
heater to gas supply. Follow all
local codes.
WARNING: This appliance
requires a 3/8” NPT (National
Pipe Thread) inlet connection
to the pressure regulator.
WARNING: Never con-
nect heater private (non-utility)
gas well. This gas is commonly
known as well-head gas.
*A CSA/AGA design-certied equipment shutoff valve with 1/8” NPT
tap is an acceptable alternative to test gauge connection. Purchase
the optional CSA/AGA design-certied equipment shutoff valve from
your dealer. See Accessories, page 18.
CAUTION: Use pipe
joint sealant that is resistant to
liquid petroleum (PL) gas.
Figure 13-B -Gas Connection
Install sediment trap in supply line
as shown in Figure 13-B. Locate
sediment trap where it is within
reach for cleaning. Locate sediment
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
ttings.
CAUTION: Use only new,
black iron or steel pipe. Internally-
tinned copper tubing may be used
in certain areas. Check your local
codes. Use pipe of large enough
diameter to allow proper gas vol-
ume to heater. If pipe is too small,
undue loss of pressure will occur.

CONNECTING TO PERMANENTLY
LOCATED 100# OR LARGERGAS
SUPPLY
CAUTION: Never connect
h e a t e r d i r e c t l y t o t h e
propane/PL supply. This heater
requires an external regulator
(not suppl ied). Install the
external regulator between the
heater and propane/PL supply.
The installer must supply an
external regulator. The external
regulator will reduce incoming gas
pressure. You must reduce
incoming gas pressure to between
11 and 14 inches of water. If you
do not reduce incoming gas
pressure, heater regulator damage
could occur. Install external
regulator with the vent pointing
down as shown in Figure 13.
Pointing the vent down protects it
from freezing rain or sleet.

Vent Pointing Down
Typical Inlet Pipe Diameters
All models up to 20,000 BTU’s use
3/8’’ or greater pipe;
All models 25,000 BTU’s and higher,
use 1/2” or greater pipe.
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 14).
IMPORTANT: Install an equipment
shutoff valve in an accessible location.
The equipment 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:Do not over tighten
gas connections.
