Introduction
The burners are suitable for operating both on boilers with flame
inversion chambers (*) (the long head model being

combustion chamber with bottom outflow (three passes), on
which the lowest NO
x

The boiler front door maximum thickness A)(Fig. 10), complete

(
*
) A kit for reducing CO is available for boilers with flame
inversion chambers, if necessary See Accessories.
The kit includes 5 gas tubes, identical to another 5 already
present in the burner head.
In standard conditions, burner head is equipped with a
second set of tubes, letting gas out in a different direction
compared to the previous tubes.
Using the kit, this second set of tube is replaced so that in the
end all tubes are the same.
After installing the kit, check its effectiveness by measuring
flue gas and CO.
