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 burner sys-
tem. 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
burner system (see Figure 43).
IMPORTANT:
Install main gas valve
(equipment shutoff valve) in an accessible
location. The main gas valve is for turning
on or shutting off the gas to the appliance.
For propane/LP connections only, the in-
staller 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, burner system regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
42. Pointing the vent down protects it from
freezing rain or sleet.

Installation Items Needed
Before installing stove and burner system,
make sure you have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas con-
nector (if allowed by local codes) (not
provided)
* An CSA/AGA design-certified equipment
shutoff valve with 1/8" NPT tap is an accept-
able alternative to test gauge connection.
Purchase the CSA/AGA design-certified
equipment shutoff valve from your dealer.
WARNING: A qualified in-
staller or service person must
connect burner system to gas
supply. Follow all local codes.
CAUTION: For propane/LP
units, never connect burner sys-
tem directly to the propane/LP
supply. This burner system re-
quires an external regulator (not
supplied). Install the external regu-
lator between the burner system
and propane/LP supply.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
Figure 42 - External Regulator with Vent
Pointing Down (Propane/LP Only)
We recommend that you install a sediment
trap/drip leg in supply line as shown in
Figure 43. Locate sediment trap/drip leg
where it is within reach for cleaning. Install
in piping system between fuel supply and
burner system. Locate sediment trap/drip
leg where trapped matter is not likely to
freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
into burner system gas controls. If sediment
trap/drip leg is not installed or is installed
wrong, burner system may not run properly.
CHECK GAS TYPE
Use proper gas type for the burner system
you are installing. If you have conflicting
gas types, do not install burner system. See
dealer where you purchased the stove and
burner system for proper burner system
according to your gas type.

Check your building codes for any special
requirements for locating equipment shutoff
valve to stoves.
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 burner system valves.
