Appendix 4 - Gas Conversion Procedure
App4
In this section we will explain how to change the unit from
natural gas to propane operation, or from propane to natu-
ral gas. It is not necessary to change any parts or orifices.
However, you must be careful to label the unit showing the
correct type of gas.
1. Remove the upper and lower front covers.
2. Find the location where the gas supply line enters the
unit. Place the Propane Gas sticker over the Natural
Gas sticker (or vice-versa).
3. The rating plate sticker is located behind the center
door panel. Fill out the gas conversion sticker, Place it
beside the rating plate sticker.
4. Confirm that the gas supply is on.
5. Start the boiler. Use the lighting procedure shown on the
inside front cover or side of the unit.
6. With a combustion analyzer, check the CO
2
levels at
both maximum and minimum input. See Section C2.
Serious injury or death could occur if the CO
2
levels are not adjusted properly.
7. Close the front covers.
This conversion shall be installed by a qualified
service agency in accordance with the manufac-
turer’s instructions and all applicable codes and
requirements of the authority having jurisdiction.
If the information in these instructions is not fol-
lowed exactly, a fire, explosion, or production of
carbon monoxide may result, causing property
damage, personal injury, or loss of life. The
qualified service agency is responsible for the
proper and complete installation. The installa-
tion is not proper and complete until the opera-
tion of the converted appliance is checked as
specified in the manufacturer’s instructions.
