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.

INSTALLATION (cont.)

PRESSURE REGULATOR

ADJUSTMENT

This control was shipped from the factory with the regulator

set as speciﬁed on the control label. Consult the appliance rat-

ing plate to ensure burner manifold pressure is as speciﬁed. If

outlet pressure adjustment is required, follow these steps.

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.

ADJUSTMENT

NOTE

If a valve has been factory-adjusted for the 2.5 to 5 inches W.C.

range, it cannot be ﬁeld-adjusted outside that range. This is

also true for valves adjusted to the 7.0 to 12 inches W.C. range

for LP gas.
