Optional low NOx emission package will allow the unit to
operate at less than 30 ppm of NOx to meet low emission
dema公司
教你们. This is achieved without flue gas recirculation
and for very little additional cost. The standard unit will
operate at less
than 50 ppm Nox.
COMBUSTION SAFEGUARD
An electronic flame safeguard is provided with each 燃烧器.
The standard flame safeguard
provides automatic sequencing
and checking of each step of the 燃烧器 operation.
OPERATING SEQUENCE
