GAS AND ALTITUDE CONVERSION
The kettle can be field converted to propane
gas or for operation at altitudes above 2000ft
elevation.
A
manometer
that
reads in 1/100" WC
and portable combustion analyzer are required.
Natural gas to Propane gas conversion:
1. Remove the right side controls
compartment side panel.
2. Locate the gas combination valve located
in the bottom
of
the controls compartment.
3. Turn S1 screw located right of manifold
pressure port (Fig. 1) clockwise to
completely close position. Then turn
counter clockwise 10 turns.
4. Pressure at inlet port should be between
11" and 13" WC.
5. Turn the unit on.
6. Fill the unit half way with cold water.
7. Run the unit for ½ hour to burn off any
residue in combustion chamber.
8. Using the combustion analyzer check
the flue gases. If the analyzer reads Co
Free Air the combustion gases should
not exceed 0.04 % or 400 PPM. If the
analyzer does not read Co Free verify the
Fig. 1
Co reading is below 100 PPM. If the reading is above, verify your settings and retest. If readings
are still high, call tech support at the number located on the front of this manual.
9. Attach the conversion data plate located in the bottom of the controls compartment with rivets
provided. The plate is to be mounted next to the kettle’s factory data plate.
10. Replace the controls compartment panel.
Propane gas to Natural gas
conversion:

2. Locate the gas combination valve located in the bottom of the controls compartment.
3. Turn S1 screw located right of manifold pressure port (Fig. 1) clockwise to completely close
position. Then turn counter clockwise 16 turns.
4. Pressure at inlet port should be between 5" and 10.5" WC.
5. Turn the unit on.
6. Fill the unit half way with cold water.
7. Run the unit for ½ hour to burn off any residue in combustion chamber.
