Air Regulation On The Combustion Head - Maintenance - baltur GI1000 LX Instrucciones De Uso

ADJUSTMENT OF AIR AT BLAST-PIPE
Warning: When, as in this case, the burner gas valves model "SKP 70 ...", altering the air regulation at the
blast-pipe, automatically and inevitable, causes a gas supply change (see chapter Working principle
of valve "SKP 70".
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

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 deflector
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. However, 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.
