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.

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 

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.

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.
