BURNER DESCRIPTION (A)
1 Combustion head
2 Ignition electrode
3 Screw for combustion head adjustment
4 Sleeve
5 Servomotor controlling the gas butterfly
valve and of air gate valve (by means of a
variable profile cam mechanism).
When the burner is stopped the air gate
valve will be completely closed to reduce
heat loss due to the flue draught, which
tends to draw air from the fan air inlet.

7 Motor contactor and thermal cut-out reset
button
8 Plug-socket on ionisation probe cable
9 Terminal strip
10 Fairleads for electrical connections by installer
11 Two switches:
- one "burner off-on"
- one for "1st - 2nd stage operation"
12 Control box with lock-out pilot light and lock-
out reset button
13 Flame inspection window
14 Minimum air pressure switch
(differential operating type)
15 Slide bars for opening the burner and
inspecting the combustion head
16 Gas pressure test point and head fixing screw
17 Air pressure test point
18 Flame sensor probe
19 Air gate valve
20 Air inlet to fan
21 Screws securing fan to sleeve
22 Gas input pipework
23 Gas butterfly valve

Two types of burner failure may occur:
• Control box lock-out: if the control box
12)(A) pushbutton (red led) lights up, it indi-
cates 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 pushbut-

MAX. DIMENSIONS (C)
Approximate measurements
The maximum dimensions of the burner are
given in (C).

head requires the burner to be opened by with-
drawing the rear part on the slide bars.
The maximum dimension of the burner when
open is give by measurement I.
