OPERATION OF THE BOILER
Turn on water and power supply.
Open cabinet door and turn main power switch ON. Pilot light ignites and water begins
to fill boiler - observe water gauge sight glass to verify that proper water level is reached.
Once the proper water level is reached, the heaters begin to heat the water. Heaters
require about 15 minutes to begin steam generation. The boiler pressure gauge in the
cabinet should indicate steam pressure in a range of 9 to 11 psig.
SHUT DOWN
Turn the Main Power Switch OFF: Open manual drain valve. If unit is supplied with
Automatic Blowdown Valve, it will open, draining the boiler and releasing hot water and
steam to the drain.
- ON fills the boiler tank and turns the boiler heaters on. You
should allow 20 minutes to fill the tank and generate steam.
- OFF shuts off the boiler heaters and opens the Automatic
Blowdown Valve, emptying the boiler tank and releasing
water and steam to the drain. This should be done daily to
remove sediment, lime, or scale.
- Indicates main power is ON.
- Should read 9 - 11 psig during operation; 0 psig during
shutdown.
Murkiness in the water indicates inadequate water quality;
the owner must supply proper water to the boiler (see page
4).
- While boiler is ON, briefly open the water level control valve
once a day to remove any sediment that might accumulate.
(See page 11 for detailed instructions.)
- This valve will release (pop off) if the boiler has too much
pressure. Once a week, this valve should be tripped during
operation to make sure it functions properly.
