IMPORTANT INSTRUCTIONS (Continued)
CAUTION: Protect yourself. When flushing control, hot water and
steam will flow out of the drain.
When flushing control, note water level in gauge glass, allow the boiler to fill if necessary, and
also to come up to temperature.
Before flushing control, note that water level in gauge glass is within operating range and the
boiler pressure is at least 6 psi. While the boiler is being fired, open blowdown valve at bottom
of control by rotating the handle counterclockwise about 1/4 turn to fully open the valve.
Opening the blowdown valve also checks the cut-off operation. Float should drop shutting
burners off, hot water and steam will flow out the drain flushing away sediment.
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.
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. Safety relief valve should be tripped during operation periodically to assure that it functions
properly.
CAUTION: Live steam will escape during this operation and may
cause personal injury.
2. If appliance is equipped with a pressure regulator, twice a year the hex plug located at the
bottom of the regulator should be removed and the strainer cleaned.
3. Burners should be cleaned on a regular basis to eliminate the accumulation of lint on burner
ventures and burner orifices.
