Carbon Dioxide Generator Gas Conversion Instructions
1. Lay generator on its right side with bottom toward you. Remove bottom plate by removing
phillips-head screws.
2. Remove the two screws and nuts holding the valve assembly mounting bracket to the left
housing side piece.
3. Remove the housing left side screws, front and back, and lift side off with burners
attached.
4. Unscrew 3/8” fitting on thermocouple lead where attached to bottom of the safety valve.
5. Remove retainer clip on top of the thermocouple. Lower thermocouple out of the pilot
head. Unscrew pilot head while holding pilot orifice with 1/2 end wrench. Remove pilot
orifice while holding pipe securely with pipe wrench. Re-install new pilot orifice using pipe
sealant (Loctite 565 is recommended).
6. Remove the existing brass burner orifice(s) from burner pipe or manifold and install the
new burner orifices using pipe sealant (do not use Teflon tape).
7. Re-install the pilot head keeping it in line with valve body, even if you have to turn one
more time full turn to get it tight. Re-install thermocouple to pilot head and safety valve.
8. Install side of housing and then the two screws and nuts for the valve assembly mounting
bracket. Fasten bottom plate back in position.
9. Install the proper pressure regular for the gas being used, either to propane tank or
incoming gas service supply line.
10. With gas “On” and switch “Off” test all fittings for leaks using soapy water (25% liquid dish
soap to 75% water). Bubbles will appear if leaks are present.
