Commercial boilers

The burner is suitable for operation on either flame-inversion boil-
ers* or boilers with combustion chambers featuring flow from the
base (three flue passes) on which the best results are obtained in
terms of low NOx emissions.
The maximum thickness of the boiler's front door must not exceed
10" (Fig. 5).
(*) For flame inversion boilers, a kit is available to reduce CO emis-
sions if required.
The kit includes 5 gas pipes, identical to the other 5 already fit-
ted to the burner head. In standard conditions, the burner head
is fitted with a second group of pipes, with gas outlet in a differ-
ent direction with respect to the others.
With this Kit, the second group of pipes is replaced, so that all
the pipes are the same.
After fitting the kit, ensure they work correctly by measuring the
CO and flue gases emissions.
