PERIODIC MAINTENANCE
(Continued)
Continue draining water for about fifteen (15) seconds from control, until water is clean.
Manually close valve. Recheck gauge glass. If water level has dropped significantly, wait for
the boiler to restore water level and pressure and repeat if necessary.
1. Observe that the water in gauge glass is clean and clear. Extreme murkiness in water
indicates inadequate water quality.
2. Safety valve should be tripped during operation once a week to assure that it functions
properly.
3. 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.
DESCALING BOILER
It is recommended that the boiler be checked every 90 to 120 days for scale build up. Regular
maintenance should be carried out at this time.
1.
With boiler empty, close manual blowdown valve. If appliance is equipped with Automatic
Blowdown, turn water supply to appliance OFF. 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 (½) half gallon (U.S.) of CLR
Descaling Solution.
If available, use the Optional Deliming assembly DPA-1 available from your dealer.
CAUTION: If heater does not shut off during blowdown, immediately
discontinue use of appliance and call for service.
