Remarks
Gas cocks are used to manually shut off the
gas supply.
A ratio regulator is used to control the air/gas
ratio. The ratio regulator is a sealed unit that
adjusts the gas pressure in ratio with the air
pressure. To do this, it measures the air
pressure with a pressure sensing line, the
impulse line. This impulse line is connected
between the top of the ratio regulator and the
burner body.
Eclipse strongly endorses NFPA as a
minimum.

Shut-off valves are used to automatically shut
off the gas supply on a gas system or a
burner.
Orifice meters are used to measure flow.
The combustion air blower provides the
