BURNER
23.1
Assembly
Attach the burner support to the boiler. Attach the burner to the support. This provides the correct
inclination of the flame tube towards the combustion chamber. Assemble the suction and return
pipes, inserting into the suction pipe the oil filter.
23.2
Oil installation
The
"Domestic"
burner is equipped with a self-aspirating pump, which permits aspiration of oil
from the deposit located on a lower level than the burner, as long as the negative pressure
measured with a vacuum gauge at the pump does not exceed 0.4 bar (30 cmHg).
23.3
Burner start up
Make sure there is oil in the deposit, the oil valves are open and power is reaching the burner.
Connect to the main switch. Unscrew the air release valve (Pressure gauge input). Then, when the
electro valve is opened, remove the flame sensor from its position and move it near to a light
source until the oil arrives. Disconnect the burner and screw in the release valve.
23.4
Combustion adjustment
As each installation is different, and has a unique combustion circuit, it is essential that combustion
conditions at each boiler are adjusted. For the guarantee to be valid, burner adjustment must be
conducted by DOMUSA TEKNIK’s Official Technical Assistance Service.
Observe the flame. If it lacks air it will be dark and produce fumes rapidly blocking the flues.
On the contrary, if there is too much air it will be white or bluish white, yielding poor performance
and in not comply with anti pollution regulations, also the excess air may impede ignition.
The flame should be an orange colour.
If due to the nature of the boiler it were difficult or impossible to view the flame, air can be
regulated by observing the fume exhaust from the uptake; if it is dark air needs to be increased to
the burner, if it is very white air must be reduced until no fumes are visible.
If you have the equipment to verify combustion gas composition, that would be the best way of
adjusting the flame, but if you do not have one to hand for the time being follow the instructions
above.
To adjust the air and burner line conditions, carefully follow the following instructions:
