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 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
burner system (see Figure 29).
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.
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, heater regulator damage could
occur. Install external regulator with the
vent pointing down as shown in Figure 28.
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 equip-
ment shutoff valve with 1/8" NPT tap is an
acceptable alternative to test gauge connec-
tion. Purchase the CSA/AGA design-certi-
fied equipment shutoff valve from your
dealer.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.

We recommend that you install a sediment
trap/drip leg in supply line as shown in
Figure 29. 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.
