TECHNICAL SPECIFICATION
Description
These atmospheric burners are fitted with a SIT gas valve and an
electrically operated relay. This gas valve has been specially developed
for atmospheric burners with automatic ignition and ionisation flame
detection.
Advantage
•
No pilot flame, therefore no gas consumption when when the
boiler is off.
•
The burner only operates when there is a demand for hot water.
•
The electric ignition requires no action.
Starting
•
Flush the gas pipe thoroughly, turn on the room thermostat and
switch the control thermostat to heat demand.
•
Open the gas tap.
•
Turn on the main switch on the control panel.
The burner is preset at the factory.
Check the supply pressure and the pressure in the
burner when starting the boiler.
