AIR REGULATION ON THE COMBUSTION HEAD (see BT 8608/1)
The combustion head is fitted with a regulation device which closes (move forward) the air flow between the disk
and the head. Thus by closing the passage, a high pressure is obtained upstream the disk also with low flow
rates. The high velocity and turbulence of the air ensures better penetration in the fuel, hence an optimal mixture
and flame stability. It might be necessary to have a high air pressure upstream the disk to avoid flame pulsation;
this condition becomes practically essential when the burner works either with an over pressure furnace or a high
thermal load. From the above it is evident that the device which closes the air on the combustion head should be
set in such a position so as to obtain always high air pressure behind the disk. Close air passage on the burner
head so as to require a considerable opening of the air shutter which controls the suction flow of the burner fan;
obviously this condition should exist when the burner is working at maximum desired output. As a rule adjustment
should be started with the device which closes the air flow on the combustion head set in an intermediate position,
and starting up the burner for a trial adjustment as previously stated. When the maximum desired burner output is
achieved, re-set the device which closes flow air on the combustion head either in a forward or backward position
so as to obtain an air flow suitable for delivery rate, with the suction air shutter considerably open. When reducing
the air passage on the combustion head, do not close it completely. Line it accurately in respect to the disk.
Remember that if an accurate alignment is not made in respect to the disk a bad combustion and excessive head
heating will result with consequent rapid deterioration. Check it through the window in the back of the burner and
then tighten up the screws which block the air control device in position on the combustion head.
Remarks: Make sure that start-up takes place normally, because if the air control device has moved forward, it
may happen that the air out-flow velocity is so high that starting up proves difficult. In this case, move
the air control device gradually backward until it reaches a position where starting up takes place
normally; this position should be final.
It is better to keep the amount of air for the 1st flame to the bare minimum if a fail-safe ignition is to be achieved
also under the most critical conditions.
SETTING THE DISTANCE BETWEEN THE DISK AND THE NOZZLE
Burners are fitted with a device which permits to change the distance between the disk and the nozzle.
The distance between the disk and the nozzle has been regulated by the manufacturer and must only be reduced
if the atomized fuel spray coming out of the nozzle wets the disk, thus causing fouling.

USING THE BURNER

The burners are fully automatic. Tripping the general circuit breaker and the switch on the burner control box turn
the units on. Burner operation is controlled by a control box described in the chapter entitled "Description of
operation". The "lockout" position in the fail-safe position the burner automatically reverts to whenever a part of the
burner or of the system fails. It is, therefore, advisable to make certain there are no problems or malfunctions in
the heating unit before "resetting" the burner. The burner can remain in the lockout position indefinitely. To reset
the unit, press the special button. The unit can also be locked out for temporary irregularities (i.e. a little water in
the fuel, air in the piping, etc.). In this case, if reset, the burner should function normally. On the other hand, if the
unit keeps cutting out (3 - 4 times in a row), do not insist. Instead, after having made certain that there is fuel in the
tank, call the authorized Service Center in your area who will remedy the situation.
MAINTENANCE
The burner do not require any special maintenance. However, it is advisable to perform the following operations,
at least once at the end of each heating season:
1) Remove the filters, nozzle, turbulence disk and ignition electrodes and clean them carefully with solvent (benzene,
trichloro-ethylene, petroleum). Do not use metal instruments to clean the nozzle (use wood or plastic).
2) Clean the photoresistance.
3) Have the boiler cleaned and, if necessary also have the flue cleaned out.
N.B. The nozzle(s) must be replaced at least once every other heating season although it may prove necessary to
do this more frequently.
