INSTALLATION INSTRUCTIONS
Ideally an exhaust system should be located directly above the appliance to exhaust steam and heat generated by the
appliance.
Set the unit in place and level using a spirit level.
Ascertain that a floor drain (open gap) is convenient to the appliance drain.
Mark hole locations on floor through anchoring holes provided in flanged adjustable feet.
Remove appliance and drill holes in locations marked on floor and insert proper anchoring devices.
Set unit back in position and re-level left to right and front to back. NOTE: If unit has factory mounted upper cooking
section then appliance should be elevated on the right 1/16" to 1/8" to assure proper compartment drainage.
Bolt and anchor appliance securely to the floor.
Seal bolts and flanged feet with Silastic or equivalent compound.
Make service connections as indicated.
OPERATION INSTRUCTION
Turn on water and power supply to appliance. Open door of cabinet and turn on Power Switch. Pilot light will come ON
and water will begin to enter boiler. Once water level has reached the proper operating level as indicated on water gauge
glass the heating elements will be energized and heat the water. When steam pressure has reached 14.5 PSI the
elements will de-energize and cycle on and off between 12-14.5 PSI. The boiler is now ready for steam generation.
Shut Down
Turn off power switch, open manual drain valve, if unit is equipped with automatic blowdown valve, it will open and drain
the boiler.
PERIODIC MAINTENANCE
Notice:
As a safety precaution, disconnect the power supply during cleaning or servicing.
1. Water level control should be opened at least once a week to blowdown sediment and scalant.
2. Observe that the water in gauge glass is clean and clear. Extreme murkiness in water indicates inadecpiate
water quality.
3. Safety valve should be tripped during operation once a week to assure that it functions properly.
4. Keep all exposed cleanable areas of unit clean at all times.
CAUTION:
TAKE EXTRA CAUTION WHEN BLOWING DOWN WATER LEVEL CONTROL OR TRIPPING SAFETY
VALVE AS EXTREME HOT WATER AND LIVE STEAM ARE PRESENT.
TROUBLESHOOTING
Water not being supplied to Boiler
1. Water supply is "OFF".
2. Defective water fill solenoid.
3. Water level control clogged or defective, unable to operate fill valve.
4. Check drain valve is closed.
5. Supply water pressure too low.
Automatic Blowdown valve does not drain
1. Defective Blowdown valve.
2. Heat exchanger build up of scalant clogging
drain lines and valve.
Boiler achieves pressure slower than normal
1. Heavy build up of lime on elements.
2. Loose element connections.
Safety Valve blows
1. Defective safety valve.
2. Pressure too high, pressure switch requires adjustment (lower) or may be defective.
AT LEAST TWICE A YEAR HAVE AM AUTHORIZED SERVICE PERSON CLEAN AND ADJUST THE UNIT FOR
MAXIMUM PERFORMANCE.
DESCALING BOILER
It is recommended that the boiler should be checked every 90 to 120 days for scale build up. Regular maintenance
should be carried out at this time.

supply Off to appliance. Turn power switch ON this will energize and close Blowdown valve.
2. Remove 3/4" pipe plug from fitting on left front of boiler.
3. Insert appropriate hose or tube through fitting and pour in (1/2) half gallon (U.S.) of CLR Descaling solution.
Or use the Optional Deliming assembly DPA-1 available from your dealer.
4. Replace 3/4" pipe plug securely.
5. Open water supply to appliance allowing water to fill boiler
to required level.
6. Let appliance cycle, allow two hours for descaling and cleaning. DO MOT TORN ON STEAM.
7. Open both the blowdown and low water level control valves for complete drainage and close both valves.
8. Turn appliance switch ON. When boiler is completely filled turn power switch OFF, this will rinse and drain boiler.
Appliance with Manual blowdown valve must be opened to drain.
