CONNECTING TO GAS
SUPPLY
WARNING:
A qualified techni-
cian must connect heater to gas
supply. Follow all local codes.
CAUTION:
Never connect heater
directly to the gas supply. This heater
requires an external regulator (not
supplied). lnstall the external regu-
lator between the heater and gas
supply.
INSTALLATION ITEMS NEEDED
Before installing heater, make sure
you have the items listed below.
l
piping (check local codes)
l
sealant (resistant to propane/LP
gas)
l
equipment shutoff valve*
l
test gauge connection**
l
sediment trap
l
tee joint
l
pipe wrench
l
Flexible Gas hose(check local code)
* A CSA design-certified equipment
shutoff valve with 1/8
"
NPT tap is an
acceptable alternative to test gauge
connection. Purchase the optional CSA
design-certified equipment shutoff

and Gas Line Access Into Stove
Cabinet
Figure 6 -External Regulator With
Vent Pointing Down
Figure 7 -Gas Connection
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. lnstall external regulator
with the vent pointing down as shown
in Figure 6. Pointing the vent down
protects it from freezing rain or sleet.
* Purchase the optional CSA design-certified equipment shutoff valve
from your dealer. See
Accessories
.
** Minimum inlet pressure for purpose of input adjustment.

WARNING:
Never connect
heater to private (non-utility) gas
wells. This gas is commonly known
as wellhead gas.
CAUTION:
Only use a new black
iron or steel pipe. Internally-tinned
copper tubing may be used in
certain areas. Check you local
codes. Use pipe of 1/2
"
diameter or
greater to allow proper volume gas
to heater. If pipe is too small, undue
loss of pressure will occur.
Installation must include an equip-
ment 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 7).
IMPORTANT
: Install equ ipment
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 pre-
vent excess sealant from going into
pipe. Excess sealant in pipe could
result in clogged heater valves.
CAUTION:
Use pipe joint seal-
an t that is resistant to g as
(PROPANE or NG).
We recommend that you install a
sediment trap in a supply line as
shown in Figure 7. Locate sediment
trap where it is within reach for cleaning.
Install in the piping system between
fuel supply and heater. Locate sedi-
ment trap where trapped matter is not
likely to freeze. A sediment trap traps
mo istu re and c ontamin ants. Th is
keeps them from going into heater
controls. If sediment trap is not in-
stalled or is installed incorrectly,
heater may not run properly.
CAUTION:
Avoid damage to
regulator. Hold gas regulator with
wrench when connecting into gas
piping and/or fittings.
