Set-up Gas Supply
The gas supply inlet connection is a 3/8” NPT male
connector located on the left hand side of the
fi
rebox.
The unit is supplied with a stainless steel
fl
ex line to
allow the appliance to be disconnected for service. An
individual shut-o
ff
valve (not supplied) is required on
the supply line ahead of the
fl
ex connector.
Use only new black iron, steel pipes, CSST, copper
tubing, or corrugated stainless steel tubing if
acceptable—check local codes. Note that in USA,
copper tubing must be internally tinned for protection
against sulfur compounds.
Unions in gas lines should be of ground joint type.
The gas supply line must be sized and installed to
provide a supply of gas su
ffi
cient to meet the maximum
demand of the appliance without undue loss of
pressure.
Sealant used must be resistant to the action of all gas
constituents including LP gas. Sealant should be applied
lightly to male threads to ensure excess sealant does
not enter gas lines.

Replace the Bypass Screw
(if using 1800SWK—Splitwood Kit ONLY)
You can access the bypass screw on the valve through
the hole in the lower front panel of the appliance when
the wall
fi
nish is not applied. Otherwise, the burner
module must be removed from the appliance.
Remove and replace the minimum rate bypass screw
from the valve with the bypass screw supplied with the
1800SWK. The screw has a rubber o-ring holding it into
the valve body and may require prying out or removing
the screw with needle nose pliers.
There are two bypass screws included in the 1800SWK
kit. The number is stamped on the screw. Use the
correct screw for your fuel type:
• #185 - for natural gas
• #170 - for propane gas
