4. VISUAL INSPECTION OF FLAME
a) The flame should burn quietly. It should be prevailingly blue, having clear outlines.
b) When the flame is not burning cleanly, there should be checked, whether openings of air
inlet (Venturi tube) are clear. If it is not the case, particles causing obstruction should be
removed.
c) In case of any doubt a gas specialist needs to be consulted.
5. POWER SUPPLY AND ELECTRICAL CONNECTION:
The appliance needs 12 V DC power supply for possible future internal lighting and
electronic stroke spark ignition. For special "Z" models, the stroke spark ignition will be
initiated by a replaceable 1,5 V battery.
ELECTRICAL CONNECTION
To connect the facility, a twin cable of 1.5 mm
2
with red and black colours should be used,
which shall be connected to the terminal placed on the rear side of the device. The poles on
this terminal are indicated + and –. You will recognise the positive pole by red colour. When
connecting the cable, in any case take care of correct poling! Electrical circuit should be fused
with 3 A safety fuse (not delivered with the device).
IN NO CASE THE DEVICE MAY BE CONNECTED TO 230 V MAINS SUPPLY!
THIS WOULD LEAD TO DEFINITE DESTRUCTION OF ELECTRIC PARTS AND
IT WOULD BE ASSOCIATED WITH A HAZARD TO THE CUSTOMER.
6. LEAKAGE OF GAS
When testing leakages of gas, we recommend you to use an electronic gas leak detector with
type approval. In case of a defect, the tap of gas supply must be closed. Contact a gas fitter,
dealer or specialised engineer.
