Service Procedures

10.   Connect the “spark” lead to the pilot burner. Be sure to route the lead around the outside of the gas lines.

11.   Replace the flame sensor on the flame sensor bracket.

12.   Apply anti-seize lubricant to mounting head screw threads. Install the pilot burner and flame sensor assembly, and tighten 

the screws.

NOTE: Route the “spark” lead and flame sensor wire away from the manifold to prevent improper operation.

13. Turn manual gas valve to the ON position.

14. Connect unit to the branch circuit and turn on the main gas supply.

15. Place pilot switch SW3 in the ON position. Check for gas soundness.

Pilot Flame Current Check:

 

WARNING: WHEN STEAMER POWER IS TURNED ON, THERE IS HIGH VOLTAGE PRESENT IN THE ELECTRICAL 

 

COMPONENTS COMPARTMENT. BE SURE THAT STEAMER IS DISCONNECTED FROM BRANCH CIRCUIT 

 

BEFORE PERFORMING ANY REPAIRS.

 

WARNING: DO NOT ATTEMPT TO LIGHT THE PILOT BURNER WITH A FLAME.

1.   Turn off steamer power.

2.   Disconnect the ground (green) wire from the igniter module.

3.   Connect a DC micrometer between the igniter ground terminal and the disconnected green wire.

4.  Ignite the pilot. The micrometer should read 3 microamps minimum.

•   If current reading is correct, replace the igniter module (see 10.13).

•   If current reading is below 3 microamps, continually check the Flame Rectification Circuit (large orange wire, spark 

electrode, pilot burner hood, and ground connections). If necessary, tighten ground connections and/or replace 
defective component(s).

5.   Check for moisture around the pilot burner, and for corrosion on the electrode and the pilot burner hood. If necessary, 

remove moisture with a dry, clean cloth. If hood and/or electrode are excessively corroded, replace pilot burner assembly.

P.   Steam Generator Gas Jet Manifolds (P/N 123704 & 123705)

1.   Shut-off power and gas to the steamer.

2.   Remove the right side panel.

3.   Turn manual gas valve to the closed position.

4.   Remove the four aluminum tubes connected to the manifolds. Disconnect using an open ended wrench.

5.   Disconnect all wire connections to the pilot.

6.   Remove the two screws from the pilot mounting bracket. Remove pilot from the gas manifold.
