CAUTION: If burner does not shut off during blowdown,
immediately discontinue use of appliance and call for service.
Continue draining water for about fifteen (15) seconds, from control until water is clean.

the boiler to restore water level and pressure and repeat if necessary.
PERIODIC MAINTENANCE
WARNING: Disconnect the power supply to the appliance before
cleaning or servicing.
1. If water in sight glass is not clear and appears murky, this indicates poor water quality and
may cause control failure. SEE WATER QUALITY STATEMENT, page 4.
2. Safety valve should be tripped during operation once a week to ensure that it is functioning
properly.
3. Clean around burners and orifices if lint has accumulated.
4. Visually ensure carry over ports are unobstructed.
5. Visually check that the flue is not obstructed.
CLEANING
DO NOT allow water near the electrical components.
At the end of the day, turn the Main Power Switch OFF (automatic blowdown drains the boiler
tank) or if equipped with manual blowdown valve, open. Wash exterior with mild detergent and
warm water, rinse, and wipe dry. Do not use steel wool on stainless steel surfaces.
