Gas Conversion
WARNING
This conversion shall be performed by a qualified service agency in accordance with the manufacturer’s
instructions and all applicable codes and requirements of the authority having jurisdiction. If the information
in these instructions is not followed exactly, a fire, an explosion or production of carbon monoxide may result
causing property damage, personal injury or
LOSS
of life. A qualified service agency is responsible for the
proper installation of this kit. The installation is not proper and complete until the operation of the converted
appliance is checked as specified in the manufacturer’s instructions supplied with the kit.
1
Ensure the electrical power and gas is shut off to the appliance.
2
Ensure correct conversion kit has been ordered. N2LPGCK for Natural gas to LP gas
or LP2NGCK for LP gas to Natural gas. Each kit should include three upper burner
orifices and two lower burner orifices.
3
To replace the upper orifices, remove the upper cover and locate the orifices. Remove
and replace with the appropriate orifices. Ensure that the orifice spuds are
TIGHT
.
4
Remove lower cover and locate the orifice to both lower burners. Remove and replace
the appropriate orifices. Ensure that the orifice spuds are
TIGHT
.
5
After the orifices have been changed, the manifold pressure on the regulator has to be
set. A manifold pressure of 5.5” water column for Natural Gas and 11” water column for
LP gas. The pressure check should be taken downstream of the pressure regulator
with gas flowing. There is a gas shut-off valve with a port for measuring gas pressure.
Turn the unit on in accordance with the instructions and adjust the regulator pressure.
The pressure regulator has a screw cap that must be removed. After the cap has been
removed, you can adjust the spring pressure with a phillips or flat screwdriver.
6
After the manifold pressure has been set, the lower burners air mixture must be set.
Adjust the lower burners (2) for proper combustion. This can be achieved by closing
and/or opening the air shutter and observing the burner flame color. If the lower burner
flame is yellow, then the burner needs more air. If the burner flame lifts off the burner,
then the burner needs less air. Adjust the lower burners accordingly.
7
Turn both upper and lower burners and observe them.
8
When observing the upper burners, visually verify that the pilot flame is a 1/4” diameter.
If the pilot flame is larger, adjust the pilot adjusting screws.
9
Once all adjustment have been complete, return the equipment back to operating
condition.
For Natural Gas:
when upper burners (3) are equipped
with No. 42 drill size orifice and lower burners (2) are
equipped with No. 32 drill size orifice.
For LP Gas:
when upper burners (3) are equipped with
No. 50 drill size orifice and lower burners (2) are equipped
with No. 41 drill size orifice.
