VL SERIES STEAMER - SERVICE PROCEDURES AND ADJUSTMENTS

2)If a spark from ignitor is present but does not ignite gas before the ignition control module locks out, (90 sec.) there may not be enough gas in the line for ignition. Verify the gas supply and gas combination control valve are both on. Turn the ignition control modules re-set switch OFF then ON to reset the module. Sparking should then resume to ignite gas. The module may need reset several times before ignition takes place.

3)If ignitor is still not sparking proceed to step 3.

3.Check the ignition control module and transformer.

A.Turn the ignition control modules re-set switch OFF then ON to eliminate a lockout condition.

B.Check for 24VAC output on the ignition control module transformer.

1)If 24VAC is present between terminals 5 & 6 on the ignition control module but ignitor is not sparking, then replace ignition control module and re-test.

2)If 24VAC is not present then ensure that transformer is receiving 120VAC input. If ignition control module transformer is receiving proper voltage, then replace ignition control module transformer and re-test.

4.After making the necessary component adjustments or replacements, check for proper operation.

ADJUSTMENT

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX. PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED.

WARNING: SHUT OFF THE GAS SUPPLY BEFORE SERVICING THE UNIT.

1.Open the front cabinet doors and turn the gas combination control valve off.

2.To measure the manifold pressure, remove the 1/8 inch NPT plug (pressure tap) on the outlet side of the valve and attach a manometer.

3.Turn the gas combination control valve and the main power switch to ON.

4.After the burner lights, compare the manometer pressure reading to the pressure chart near the end of this procedure.

A.If other appliances are connected to the same gas line, turn them all ON and check manometer pressure reading again. If the pressure drops ½ inch water column or more, then the incoming pressure should be checked. then the gas supply needs to be checked by the gas line installer or the local gas company for adequate sizing.

B.If no other gas appliances are connected to the gas line or the pressure does not drop as described above but the manifold pressure still requires adjustment, proceed to step 5.

5.Remove the adjustment screw cap to access the pressure adjustment screw.

6.After the burner lights, set the pressure as outlined below.

A.To increase pressure, turn the screw clockwise.

B.To decrease pressure, turn the screw counterclockwise.

NOTE: Accurate gas pressure adjustments can only be made with the gas ON and the burner lit.
