WARNING:

SHUT OFF THE GAS SUPPLY

BEFORE SERVICING THE UNIT.

1. Open the cabinet base door to access main gas

valve.

2. Remove the manifold pressure tap plug from

the outlet

side of valve.

A. Install a hose barb adaptor and attach a

gas pressure manometer.

3. Turn the gas supply and power switch ON.

A. Once the boiler fills, press the reset switch

to start the ignition process.

NOTE:

The reset switch can be pressed after

the green ready light on the switch comes ON.

This indicates the water level in the boiler is at

the minimum operating level.

4. After the main burner lights, allow the boiler to

reach operating pressure then compare the gas

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 gas supply needs to be

checked by the gas line installer or the

local gas company for adequate sizing.

NOTE:

The gas supply line to the steamer

should be a minimum of one inch diameter

(ID).

B. If 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. With the burner lit, 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.
