FUEL CONVERSION
The GABO Gas Stove is shipped from the factory equipped to burn natural gas. If you will be burning pro-
pane (LP) gas you must convert the stove by replacing the burner orifice and valve regulator and adjusting
the pilot fuel selector plate and primary burner air setting. This should be done before the stove is set up.
Follow the instructions on page 14 for removing the stove front and glass/glass frame assembly from the
stove. If the logs are in place on the burner, remove them and set them aside in a safe location.
Burner Orifice
Locate the burner hold down bolt. It is located on the
underside of the firebox above the valve. Open the
control access door by pulling forward and rotating
down. See the adjacent illustration for help in deter-
mining the hold down bolt location. Using a 7/16”
wrench, remove the bolt and set aside.
Pick the left end of the burner assembly up a few
inches and then lift the burner straight up to disengage
the burner assembly from the primary air adjuster sys-
tem. The burner assembly is somewhat heavy so take care in handling. Set the burner assembly aside in a
safe location to avoid damage. Place an 11/16” open end wrench on the orifice holder fitting to secure it and
loosen the orifice using a 9/16” wrench or preferably a deep socket. Set the old orifice aside and install the
new orifice. Again,
be sure to use a stabi-
lizing wrench on the
orifice holder fitting
and be sure the orifice
is tight in the orifice
holder fitting. Note:
The orifice holder and
orifice are brass com-
ponents and could
break if over-
tightened Refer to
the two adjacent illus-
trations.
Primary Air Adjuster
The primary air adjuster screw is located under the firebox near the control valve. It is factory set in the
fully closed position for natural gas. For propane the proper setting is fully open. Loosen the locknut and
back the screw out until you observe the primary air shutter has reached the fully open position. Retighten
the locknut.

Burner Orifice Installation (when rear-venting directly through the wall)
Follow the procedure above for replacing the burner orifice if you are rear venting your stove directly
through a wall to a horizontal termination. The proper orifices for this purpose are included with your
stove. For natural gas, use the #39 orifice. For propane (LP) gas, use the #53 orifice. Refer to page 12 of
this manual for more information.
Pilot Orifice
The pilot is convertible from one fuel to the other by simply loosening the pilot hex (using a 7/16” open end
wrench) and sliding the orifice strip to the correct position for the fuel you are using.
Turn the pilot hex 1/4 turn counter-clockwise
taking care not to contact the orifice strip or either of the
igniter electrode
. Refer to the illustrations on page 24.
