The combustion air blower
provides the combustion air
pressure to the burner (s).
The air pressure switch gives a
signal to the safety system
when there is not enough air
pressure from the blower.
Gas cocks are used to manually
shut off the gas supply on both
sides of the main gas shut-off
valve train.
Solenoid valves are used to
automatically shut off the gas
supply on a bypass gas system or
on small capacity burner systems.
Manual butterfly valves are used to
balance the air or gas flow at each
burner, and/or to control the zone
flow.
Automatic butterfly valves are
typically used to set the output of
the system.
