DESCRIPTIONDESCRIPTION

The 25M01A series valve is a combination gas pressure
regulator and dual automatic gas valve. These valves are
designed for gas clothes dryers with Hot Surface Ignition
(HSI) systems. These valves are equipped with redundant
and main solenoid valves that control the gas flow to the
burner, and a direct acting pressure regulator.

INSTALLATIONINSTALLATION

INSTALLATION

INSTALLATIONINSTALLATION

1. Before attempting to service dryer, unplug power cord,
turn off main gas supply and consult dryer manufactur­er's instructions for accessing gas valve.

2. Disconnect exhaust vent duct.

3. Disconnect gas line from rear of dryer.

4. Remove access panel from dryer. On some models this
involves removing the entire front panel.

5. The gas valve/burner assembly should now be visible.

6. The burner assembly consists of (see figure 1 & 2):
a. Gas inlet pipe.
b. Brass inlet fitting with union – some models may also

have a manual shut-off valve.
c. Gas valve.
d. Mounting bracket.
e. Burner orifice.
f. Burner assembly with air shutter.
g. Igniter.
h. Radiant sensor – located on heat exchanger on

some models.

7. Disconnect the wiring harness from gas valve and
igniter.

8. Remove screw(s) fastening the mounting bracket to the
bottom of dryer.

9. Burner assembly should now be free to slide out of the
front of dryer. Take care not to bump or jar igniter. It is
very fragile.

10. Remove the gas inlet pipe by unscrewing the union.

11. Remove screw(s) fastening the gas valve to the mount­ing bracket and set them aside. They will be reused.
