Remarks
Eclipse strongly endorses NFPA
as a minimum.
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 burners.
The pressure regulator reduces
gas pressure to a stable, usable
pressure.
The combustion air blower
provides the combustion air
pressure to the burner(s).
