The gas line must be installed in accordance with all
local codes, if any (and Commonwealth of Massachusetts
approved); if not, follow NFGC ANSI 223.1 or CAN/
CGA-B149 and the requirements listed below.
NOTE: Have the gas supply line installed in accordance
with local building codes by a qualified installer
approved and/or licensed as required by the locality.
(In the Commonwealth of Massachusettes installation
must be performed by a licensed plumber or gas fitter.)
A listed (and Commonwealth of Massachusetts approved)
1/2 inch (13mm) tee-handle manual shut-off valve and a
listed flexible gas connector are connected to the 1/2 inch
(13mm) inlet of the control valve.
NOTE: If substituting
for these components, please consult local codes for
compliance. Leak test all gas line joints and the gas
control valve prior to and after starting the stove.
The stove and gas control valve must be disconnected
from the gas supply piping during any pressure testing of
that system at test pressures in excess of 1/2 psig (3.5
kPa). For pressures under 1/2 psig (3.5kPA), isolate the
gas supply piping by closing the manual shut-off valve. Be
sure to bleed off test pressure before opening shut off.
Fuel
This unit is manufactured for use with natural gas. To
convert to LP gas, use the LP Conversion Kit supplied with
the stove.
Gas Line Connection
Before making the gas connection, ensure that the stove
you are installing is designed for the type of gas being
supplied. This information can be found on the Ratings
Label attached to a beaded chain on the lower right hand
side of the appliance. If the stove has been converted to
propane (LP), the valve cover will have a label stating that
the unit has been converted to propane. (
See page 11,
#5
).
Connect the gas line at the 3/8” flex connector on the valve
at the back of stove. See illustration on this page. We
recommend connecting the stove with an approved flex gas
line. If flex gas lines are not approved in your area, you
must connect a hard pipe to the gas hookup.
You must supply a manual shutoff valve in a visible location
within 3’ (91.4cm) of the stove.
GAS LINE REQUIREMENTS
CAUTION: In some areas, gas line pressure may
be more than 1/2 PSIG (14”WC). If you believe
that this is the case in your locality, contact
your gas supplier or local utility company. Line
pressure greater than 1/2 PSIG will damage
the stove valve. You must install a regulator
upstream from the stove if line pressure is
greater than 1/2 PSIG.

After running new gas line, or if a gas line has been
disconnected, purging of the gas line may be necessary.
To purge gas line, open the inlet pressure tap and allow
gas to flow through while carefully monitoring for the odor
of either natural gas, which will rise, or propane, which
will settle near the floor. As soon as you smell the gas,
discontinue purging the line. Ensure that the room has
plenty of ventilation and that no sparks or open flames are
near the end of the gas line during the purging process. Do
not try to ignite the stove until any and all gas accumulation
has been cleared from the room.
