Installation
5.4 Operating position
5.5 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
x
emissions are obtained.
The maximum thickness of the front hatch of the boiler
A)(Fig. 13), complete with refractory, must not exceed:
Tab. L
( * ) For flame inversion boilers, a kit is available to reduce the
CO. 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 il-
lustrated in Fig. 14.
The position of the threaded holes can be marked using the ther-
mal insulation screen supplied with the burner.

WARNING

The burner is designed to operate only in
positions
1 , 2 , 3 and 4 (Fig. 12).

Installation 1 is preferable, as it is the only
one that allows the maintenance operations
as described in this manual.

Installations 2 , 3 and 4 permit operation but
make maintenance and inspection of the
combustion head more difficult.
DANGER

Any other position could compromise the cor-
rect operation of the appliance.

Installation 5 is prohibited for safety reasons.
