14.0 Converting to ULPG or Propane:
Where a conversion to ULPG or Propane is needed, the following steps should be followed
14.1
First you need to remove the burner by
removing the screw holding it in place on the
left hand side of the firebox (Fig. 1).
Then remove the burner jet (Fig. 2) and
replace it with the 1.3mm jet (Propane) or
1.25mm jet (ULPG) supplied in the kit.
Now remove the gas pipe fitting under the
pilot (Fig. 3) and remove the pilot Jet (Fig. 4)
and replace it with the No.46 pilot jet supplied
in the kit. No. 46 is used for both ULPG &
Propane
Replace the pilot line.
Set the Primary Aeration Collar on
the burner to the ULPG/Propane
position as shown in the diagram by
removing the screw in the side and
then replacing it when the collar is in
the correct position.
NOTE: the collar is only able to be
set to either NG or Propane/ULPG
positions. This is not an adjustable
system.
Place the burner back into the
appliance and screw it in place.
The gas regulator needs to be converted from the Natural Gas setting to the LPG/Propane
setting.
The regulator is located on the left hand side of the control tray, at the base of the fire.
To change the regulator between Natural Gas and Propane, remove the regulator screw
cap and screw out the nylon adjuster screw to remove the existing spring.
Replace the spring with the purple spring supplied in the conversion kit and reassemble the
regulator.
Set the pressure using the instructions in section 16.0
