6. Replace the mixing tube on the burner housing by
removing the two (2) screws that secure the mixing
tube to the burner housing assembly. Remove the
old gasket behind the mixing tube. (Fig. 10) NOTE:
The mixing tube for propane gas has only two
bimetallic springs that are in the closed position
at cold start. The mixing tube for natural gas has
two spring/shutter collar assemblies that are in
the closed position at cold start. Make sure the
correct mixing tube is used for conversion.
7. Use the new gasket supplied in the conversion kit
and proper mixing tube and replace in reverse order.
8. Reassemble the burner housing assembly, the
burner tube assembly and the fettle in reverse orde
