STOVE AND DIRECT-VENT
BURNER SYSTEM
INSTALLATION
CHECK GAS TYPE
Use proper gas type for the burner system unit 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. Conversion kits are also
available for these models, see Accessories on page 38.
IMPORTANT: If installing gas conversion kit, do so at this time.
Be sure to follow all installation instructions included with
conversion kit.
INSTALLING GAS PIPING TO STOVE/
BURNER SYSTEM 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.
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,
burner system regulator damage could occur. Install external regu-
lator with the vent pointing down as shown in Figure 39. Pointing
the vent down protects it from freezing rain or sleet.

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 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 40).
IMPORTANT: Install main gas valve (equipment shutoff valve) in
an accessible location. The main gas valve is for turning on and
shutting off the gas to the appliance.
Check your building codes for any special requirements for locating
equipment shutoff valve to stoves.
