1. GENERAL INFORMATION
The NPM NOVA Premix
f
burner employs a fully premixed high swirl stabilized combustion head
technology to provide proven low NO
X
emissions for sub 30 PPM applications and superior flame
retention. NO
X
emissions lower than 30 PPM can be obtained by running at slightly higher 0
2
levels. The
NPM burner is designed to fire natural gas and propane against a positive, balanced or negative furnace
pressure.
The burner is a self-contained unit comprised of a blower assembly, firing head, ignition system, and
flame safeguard control panel. As with any premix burner the excess 0
2
operating range is narrower than
those of a conventional nozzle mix gas burner. Therefore, during setup care should be exercised in
obtaining an excess 0
2
reading of not less than 2% or more than 7%.
All Power Flame burners are operationally fire tested at the factory.
