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. Water level control should be opened daily to blowdown sediment and scalant.
2. Observe that the water in gauge glass is clean and clear. Extreme murkiness in
water indicates inadequate 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: Disconnect the power supply during cleaning or
servicing.
