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.
CLEANING
CAUTION: Do not use cleaning agents that are corrosive.
1. Keep exposed cleanable areas of unit clean at all times.
2. Thoroughly wash oven cavities, door liners, and pan racks at the end of each day, or
as required, with a mild detergent and water to prevent bacterial growth and odours.
3. Remove drain screens from inside compartment drains. Using a plastic bottle brush
and mild detergent, clean inside the drain opening ensuring there is no food residue
