Flame Monitoring Control
The flame monitoring control is the equipment that processes
the signal from the flame rod or the U.V. scanner.
For flame monitoring control you may select several options:
• flame monitoring control for each burner: if one burner goes
down, only that burner will be shut off
• multiple burner flame monitoring control: if one burner goes
down, all burners will be shut off
There are three recommended flame monitoring controls:
• Bi-flame series; see Instruction Manual 826
• Multi-flame series 6000; see Instruction Manual 820
• Veri-flame; see Instruction Manual 818
Other manufacturer’s flame monitoring systems can be used
with the burner if spark is maintained for a fixed time interval
and is not interrupted when a flame signal is detected during trial
for ignition.
ImmersoJet burners are sold in these configurations:
• Burner with integral low pressure blower.
• Burner with integral high pressure blower.
• Burner less blower.

Effects of atmospheric conditions
The blower data is based on the International Standard
Atmosphere (ISA) at Mean Sea Level (MSL), which means that it
is valid for:
• sea level
• 29.92” Hg (1,013 mbar)
• 70ºF (21ºC)
The make-up of the air is different above sea level or in a hot
area. The density of the air decreases, and as a result, the outlet
pressure and the flow of the blower decrease. An accurate
description of these effects is in the Eclipse Combustion
Engineering Guide (EFE 825). The Guide contains tables to
calculate the effect of pressure, altitude and temperature on air.
