ADJUSTMENT OF AIR AT BLAST-PIPE
When, as in this case, the burner gas
Warning:
valves model "SKP 75 ...", altering the
air regulation at the blast-pipe, automati-
cally and inevitable, causes a gas supply
change (see chapter Working principle of
valve "SKP 75".
The blast-pipe has an adjustable deflector disk for the
opening and closing of the flow of air between the disk
and the combustion head. By closing the path, high
pressure is also obtained upstream of the disk, even at
low capacities. This narrowing of the air flow creates an
increase in pressure before the deflector disk resulting
The high speed air and air turbulence, thus providing
optimum mixing with the fuel and good flame stability. It
may be necessary to have high air pressure before the
disk to prevent flame fluctuations, particularly essential
when the burner works on the combustion chamber that
is pressurized and/or at a high thermal load.
It is clear from the above that the device that closes the
air to the blast-pipe must be set at a position such as to
always obtain very high air pressure behind the disk.
N.B. See table to help with blast-pipe regulation
(diagram 0002934020) below shows 3 types
of adjustment: "ULTRA LOW NOX, LOW
NOX, HOT. The burner is factory set at "LOW
NOX" configuration (in heavy type in diagram

By reducing the blast-pipe air flow, avoid complete
closure which could cause excessive heating up of
the combustion head and its rapid deterioration.
Ensure true centring relative to the disk. If disk
centring is not true, poor combustion may result
and excessive combustion head heating which will
result in its rapid deterioration. To move the deflec-
tor disk unscrew the four screws indicated in the
photo and move the disk to the desired position.

MAINTENANCE
The burner does not need special maintenance. How-
ever, it is advisable to check that the gas filter is clean.
It may also be necessary to clean the combustion head.
In this case, dismantle the components of the mouth.
Be careful when assembling again, so as to prevent
the electrodes from to earth or in short circuit.
It is also necessary to check that the pilot tube
ignition electrode spark only occurs between this
and its disk.
