BURNER DESCRIPTION (A)
1 Ignition electrodes
2 Combustion head
3 Screw for combustion head adjustment
4 Screw for fixing fan to flange
5 Slide bars for opening the burner and inspect-
ing the combustion head
6 Safety solenoid valve
7 Pump
8 Air inlet to fan
9 Air gate valve
10 Hydraulic cylinder for regulation of the air
gate valve in 1st and 2nd stage positions.
When the burner is not operating the air gate
valve is fully closed in order to reduce heat
dispersion from the boiler due to the flue
draught which draws air from the fan suction
inlet.
11 Fan pressure test point
12 Boiler mounting flange
13 Flame stability disk
14 Electrical motor
15 Extensions for slide bars 5)
16 Ignition transformer
17 Motor contactor and thermal cut-out with re-
set button
18 1st and 2nd stage valve assembly
19 Terminal strip
20 Two switches:
- one "burner off - on"
- one for "1st - 2nd stage operation"
21 Fairleads for wiring carried out by the installer
22 Control box with lock-out pilot light and lock-
out reset button
23 Flame inspection window
24 Pump pressure adjustment
25 Photocell for flame presence control
Two types of burner failure may occur:
Control box lock-out: if the control box 22)(A)
pushbutton (red led) lights up, it indicates that
the burner is in lock-out.
To reset, hold the pushbutton down for between
1 and 3 seconds.
Motor trip: release by pressing the pushbutton
on thermal cutout 17)(A).
PACKAGING-WEIGHT (B)
Approximate measurements
• The burner stands on a wooden base which
can be lifted by fork-lifts. Outer dimensions of
packaging are indicated in (B)
• The weight of the burner complete with pack-
aging is indicated in table (B).
MAX. DIMENSIONS (C)
Approximate measurements
The maximum dimensions of the burner are giv-
en in (C).
Bear in mind that inspection of the combustion
head requires the burner to be opened and the
rear part withdrawn on the slide bars.
The maximum dimension of the burner when
open is give by measurement I.
