Connect the Gas Line
Gas connection should be made in accordance with the
current edition of the National Fuel Gas Code, ANSI
Z223.1. Since some municipalities have additional local
codes, be sure to consult your local authority.
CAUTION
• The gas line should be connected only by a
qualified gas technician. Test to confirm
manifold pressures as given below.
• There must be a gas shutoff valve installed
between the stove and the supply line.
With natural gas, use a 3/8” or 1/2” natural
gas supply line with an input of 35,000 BTUs at
a manifold pressure of 3.5” W.C. and minimum
inlet supply for adjustment of 5.0” W.C.
With propane, use a 3/8” or 1/2” propane
gas supply line with an input of 35,000 BTUs at
a manifold pressure of 11.0” W. C. and minimum
inlet supply for adjustment of 11.0” W.C.
Thermostat Connection
(optional)
Use only a millivolt rated thermostat. Check the table
below for the appropriate gauge thermostat wire to use
for the length of lead required in your installation.
Thermostat
Wire Gauge / Maximum Run
18 40 feet
20 25 feet
22 16 feet
1. Install the wall thermostat in the desired location and
run the wires to the stove location. Terminate these
leads with 1/4" spade connectors.
2. Connect the thermostat wires to the two 1/4" female
connectors extending out of the control valve wire
harness. These wires are accessible from under the
left rear side of the stove. Either thermostat wire may
connected to either terminal. (Fig.16)
3. Place the control switch on the rear of the stove in
the “T’STAT” position and set the wall thermostat at
its lowest setting until the heater is ready for opera-
tion.
1. Remove the valve coverplate. Use a stub handle
phillips screwdriver to loosen the two retainer screws
and pull the coverplate forward. (Fig. 17)
2. Connect the main gas supply line to the inlet on
the left side of the control valve. (Fig. 18)
The gas line connection can be made with properly
tinned 3/8” copper tubing, 3/8” rigid pipe, or an
approved flexible connector. When using copper or
flexible connectors, use only approved fittings.
Always provide a union so the gas line can be easily
disconnected for burner service.
3. Test for leaks at all joints with a 50/50 solution of
liquid soap and water to test for leaks at gas fittings
and joints. Apply water/soap solution with a brush
only -
do not over apply. NEVER! test with an open
flame.
4. Reinstall the coverplate over the control valve by
engaging the slots on the back of the plate, with the
retainer screws. Retighten the screws.
5. Light the pilot according to the directions on pages
15-16 . It may take several minutes to fully bleed the
5-gas line of any air.
When you have confirmed that the pilot lights properly,
shut it off and complete the installation.
Fig. 16 Attach leads for an optional thermostat to the
connectors at the lower left rear corner of the stove.
