INSTALLATION (cont.)

12.The gas valve should now be free to slide out of burner and off of mounting bracket. Take care not to disturb the air shutter.

13.Remove inlet fitting from old gas valve and set it aside. Take care not to damage the sealing surfaces. This part will be reused.

14.Clean the threads of the inlet fitting. Apply pipe sealant (approved for all gases) to the threads. Install the fitting into the inlet of the new valve and tighten to 200 lbf-in (16.6 lbf-ft) using a 3/8 inch hex head wrench.

15.Remove orifice screw from old gas valve and set it aside. Take care not to damage the sealing surfaces. This part will be reused.

16.Inspect the threads of the orifice screw and clean if necessary.

17.Inspect the orifice hole and remove any foreign material.

18.Install orifice screw into new valve and tighten to 40 lbf- in. Do not use any pipe sealant.

19.Slide the outlet boss of the new valve into the burner. Take care not to disturb the air shutter.

20.Fasten the gas valve to the mounting bracket using the screw(s) removed earlier.

21.Connect the gas inlet pipe to the inlet fitting by threading the union together and tightening to 150 lbf-in (12.5 lbf- ft).

22.Insert the burner assembly back into the dryer so that the gas inlet pipe exits through the square hole in the back of the dryer cabinet, and the burner fits inside the heat exchanger. Take care not to bump or jar igniter. It is very fragile.

23.Fasten the mounting bracket to the bottom of the dryer cabinet using the screw removed earlier.

24.Reconnect the wiring harness to the igniter and the gas valve.

25.Reconnect the exhaust vent duct to the back of the dryer.

26.Apply pipe sealant to the threads of the inlet gas pipe and reconnect the gas line to the back of the dryer and tighten.

27.Turn on gas supply and Check for leaks.

28.Remove the outlet pressure tap from the gas valve (see figure 3). Apply pipe sealant to the 1/8-inch NPT threads of a hose barb. Install the hose barb into the outlet pressure tap and tighten to 40 lbf-in (see figure 4).

29.Connect a manometer to the hose barb. Manometer should be capable of measuring pressure from 2.5" WC up to 14.0" WC.

30.If entire front cover was removed, the connector for the door switch must be temporarily jumpered. Otherwise the dryer will not function.

NOTE: On some dryers, the front cover supports the drum. On these models, the drum must be removed in order to energize the system and adjust the regulator.

31. Plug dryer power cord into electrical socket.

32. Energize dryer and verify ignition. Also observe the reading on the manometer. It should read the same outlet pressure as stated on the rating plate on the old gas valve. If it does not, see section on Pressure Regulator Adjustment.

33.De-energize the dryer.

34.Remove the hose barb.

35.Apply pipe sealant to the 1/8 inch NPT plug screw. Install the 1/8 inch NPT plug screw into the outlet pressure tap and tighten 40 lbf-in.

36.Check for leaks.

37.Remove temporary jumper from door switch connector and reconnect to door switch.

38.Reinstall the access panel/front cover.
