OPERATING INSTRUCTIONS

3.1GAS BURNER

So far as is necessary, the pilot burner and main burner are cleaned by after-sales service.

5.STORAGE SPACE

The storage space (Fig.10) is incorporated into the base unit. Recommended accessories:

3.2FLAME

In a visual check, the flames must be dark blue without any upper yellow or orange tips; they must be stable and soot-free and adhere firmly to the outlets.

If there is a lack of primary air, the flame has yellow streaks and tips; if there is too much primary air, the flame is short, transparent and tends to lift off the burner.

When the flame is correctly adjusted, it must not lift off or back- fire when the burner is cold as well as warm.

The flame will backfire into the inside of the burner when the speed of the gas-air mixture through the burner outlets is too low, particularly when the air passages are dirty.

The different ignition processes must also take place without any delays. This concerns: ignition, arc-through and. extending the flame over the whole burner area.

If the flame fails to meet all the requirements, cleaning or maintenance is necessary.

4.MALFUNCTION

The burners are not accessible to operating personnel. Therefore, in the case of a fault, specialist staff must be reque- sted.
