Preparing the boiler

5.5.1

Introduction

The burners are suitable for working on both flame inversion
boilers (
*
) (in this case the long head model is recommended)
and boilers with a combustion chamber with bottom runoff
(three flue gas circulations), from which the best results of
low NO
emissions are obtained.
x
The maximum thickness of the front hatch of the boiler
A)(Fig. 13), complete with refractory, must not exceed:
Blast tube
RS 68-120/E BLU
RS 160-200/E BLU
(
*
) For flame inversion boilers, a kit is available to reduce the
CO, if necessary (excluded RS 200/E BLU model).
See Accessories.
The kit consists of 5 gas tubes, identical to the other 5 al-
ready present in the burner head. In standard conditions, the
head of the burner is fitted with a second group of tubes, from
which the gas emerges in a different direction compared with
the others.
With the kit, this second group of tubes is substituted so that
all the tubes are the same.
After assembling the kit, check its efficiency by measuring
the flue gases and CO.
5.5.2

Boring the boiler plate

Drill holes in the plate shutting off the combustion chamber, as
illustrated in Fig. 14.
The position of the threaded holes can be marked using the ther-
mal insulation screen supplied with the burner.
