Remove the burner orifice from the valve and replace it with the proper orifice furnished in this kit. The orifice number is stamped on one edge of the hex head of the orifice. Securely tighten. See Figure 4.
Use Orifice No. 54 for Propane gas.
Use Orifice No. 55 for Butane gas. -
Put the burner tube back on the burner assembly. Securely tighten the two (2) mounting screws. Reconnect the ignitor to the harness. See Figures 3 and 4.
-
Before proceeding, you must first determine which gas valve style is on the unit. Refer to Figure 5 – Style “A” and “B”.

- Remove the pressure tap plug from the gas valve body.
- Insert pressure tap finger tighten and connect the monometer hose to the end of the nipple.
- Turn on the gas supply. If your dryer is equipped with a manual valve, make sure that it is in the on position.
- Verify gas inlet pressure is between 8” and 13” water column.
- Turn off the gas supply. If your dryer is equipped with a manual valve, make sure that it is in the off position.
- Remove the manometer and pressure tap and replace the plug.
Leak Check
- Turn on the gas supply. If your dryer is equipped with a manual valve, make sure that it is in the on position.
- Brush or spray a soap and water solution onto the pressure tap and union nut and inspect for leaks indicated by growing bubbles.
- If the dryer was moved during conversion, use this same method to check for leaks in the flexible gas supply line and any fittings between the dryer and the gas supply pipe.
- If any bubbles are present, tighten the leaking connection and retest for leaks.

24. Reassemble the front panel in reverse order. (Refer to steps 7 and 8).
Before closing the top, check the following:
a. Belt should be centered and tight on the drum.
b. Wire clips holding the door switch wires must be anchored in slots in the
top of the front panel and along the top edge of the side panel. See Figure
