Step 3. Remove three (3) screws from the back of the burner tray. Lift the rear of the burner tray up slightly and to the right to disengage the burner tube from the manifold and orifice. Remove the burner tray.
Step 4. Millivolt Appliances – Remove and replace the regulator assembly located on the front of the gas valve (Figure 39 ). Ensure that the gasket is seated properly and is not kinked.

Step 6. Remove the orifice from the manifold and replace it with the one provided in the kit; 5500 models - #43 for natural gas and #54 for propane, 6500 models - #41 for natural gas units and #53 for propane.
Step 7. Replace the pilot orifice with the one provided with the kit (Figure 41).
Step 8. Reassemble all removed components by reversing the procedures outlined in the preceding steps. Use pipe joint compound or Teflon tape on all fittings before installing (en- sure propane resistant compounds are used in propane applications).
