* Purchase the optional CSA/AGA design-certified equipment shutoff valve from your

dealer. See Accessories, page 19.

** Minimum inlet pressure for purpose of input adjustment.

 CAUTION: Avoid damage to

regulator. Hold gas regulator with
wrench when connecting it to gas
piping and/or fittings.

 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 18).

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: Never connect

heater to private (non-utility) gas
wells. This gas is commonly
known as wellhead gas.

The gas inlet connection for the stove heater
is located on the lower right-hand side of the
stove when viewed from the front of the
unit. The gas connection can be made either
through the bottom right side or through the
lower back opening as illustrated in Figure
17.  Make sure gas log heater is secured to
the stove cavity assembly.

 CAUTION: Use pipe joint seal-

ant that is resistant to liquid pe-
troleum (LP) gas.

We recommend that you install a sediment
trap in supply line as shown in Figure 18.
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.

CONNECTING TO GAS
SUPPLY

 WARNING: This appliance re-

quires a 1/2" NPT (National Pipe
Thread) inlet connection to the
pressure regulator.

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 19.
