Gas Supply Connection
NOTE: If appropriate, install the optional forced air
blower before connecting the gas line, to prevent
clearance interference between the two.
The gas supply line connection is made to the left
side of the valve. The gas supply line should be 3/8” npt
with a 1/2” diameter supply, or the appropriate size to
provide sufficient gas pressure to the valve regardless
of the input setting.
The use of Flexible Gas Appliance Connectors is
acceptable in many areas in the U.S. However, Canadian
methods vary depending on local code.
ALL INSTALLATIONS MUST COMPLY WITH LOCAL
CODE OR IN THE ABSENCE OF LOCAL CODE, MUST
COMPLY WITH THE MOST RECENT EDITION OF THE
NATIONAL FUEL GAS CODE ANSI Z223.1/NFPA 54 OR THE
NATURAL GAS AND PROPANE INSTALLATION CODE CSA/
CAN-B149.
All codes require a gas shut-off valve (gas cock) and
union, to be installed in the supply line, and in the same
room as the appliance. This allows for the disconnection
of the stove for servicing and maintenance. See fig. 36.
A T-HANDLE GAS COCK IS REQUIRED IN
MASSACHUSETTS TO COMPLY WITH CODE 248CMR.
Leak test:
1. Mix a 50-50 solution of water and dish
soap.
2. Light appliance- see lighting instructions
on the inside back cover of this manual or
on the stove’s rating plate.
3. Brush or spray all joints and connections
with the soapy water solution.
4. If bubbles appear at any connection or
seam or a gas odor is detected, imme-
diately turn gas control knob to the OFF
position.
5. Tighten or reconnect the leaking joint
and retest for any gas leaks.

Secure all joints tightly using appropriate tools and
sealing compounds. For propane units be sure to use com-
pounds that are propane resistant. Turn on gas supply and
test for gas leaks using a soapy water solution. Never use
an open flame to check for leaks.
