CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in cer-
tain areas. Check your local codes. Use pipe of 1/2"
diameter or greater to allow proper gas volume to
burner system. If pipe is too small, undue loss of
volume will occur.
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 connector (if allowed by lo-
cal codes) (not provided)
* A CSA design-certified equipment shutoff valve with 1/8" NPT
tap is an acceptable alternative to test gauge connection. Purchase
the CSA design-certified equipment shutoff valve from your dealer.
For propane/LP connections only, 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 27. Pointing the vent
down protects it from freezing rain or sleet.

B-VENT BURNER SYSTEM
INSTALLATION
Continued
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 28).
Check your building codes for any special requirements for locating
equipment shutoff valve to stoves.
Apply pipe joint sealant lightly to male NPT threads. This will
prevent excess sealant from going into pipe. Excess sealant in pipe
could result in clogged burner system valves.
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.

LOCATION
WARNING: A qualified installer or service person
must connect burner system to gas supply. Follow all
local codes.
CAUTION: For propane/LP units, never connect
burner system directly to the propane/LP supply. This
burner system requires an external regulator (not
supplied). Install the external regulator between the
burner system and propane/LP supply.
