3.4 CONNECTION TO THE FUEL SUPPLY
Always observe the installation, adjustment and operating
regulations stipulated by the local and/or national laws regarding
the use of air heaters.
• Before planning the exhaust system, inform the responsible
chimney sweep according to DIN 18160.
• Risk of injury due to poisoning!
• Improper installation of the exhaust system can cause health
problems.
• Have the device installed by an expert technician!
• Have the exhaust emission of the burner checked at regular
intervals.
In order to connect the device to the fuel oil pipe, the fuel oil tank can
be connected to the burner pump:
• directly using the fuel oil pump of the burner while observing
the dimensions and lengths specified in the burner's operating
manual included in the annex of this operating manual;
•
indirectly using an auxiliary pump for the fuel oil.
In this case please contact the technical service for a proper
dimensioning of the system.
3.5 CONNECTION OF THE BURNER'S AIR INLET
The combustion air inlet (3) can be connected to the outdoor area
of the room to be heated so that fresh air can be sucked in without
reducing the oxygen content of the room.
A pipe must be provided for this purpose to prevent narrowing due
to the negative pressure of the intake air. The pipe should have a
diameter of at least 100 mm and a length not exceeding 6 m.
m
Shorten pipes which are too long. There must be no kinks
and/or curves which might obstruct the intake of air.
Connecting the air inlet of the burner:
• Remove the cover (1) of the burner housing.
• Remove the end plate (2) of the burner housing.
• Guide the air hose (3) through the hole in the end plate (2) and
fasten it to the air intake snorkel (4) of the burner.
• Slide the cover (1) of the burner housing along the air hose (3)
and attach it to the burner housing. While doing so, make sure
that the air hose (3) does not slip off the air intake snorkel (4).
• Fasten the plate (1) to the air inlet of the burner. It must be rotat-
ed so that the air hose (3) is blocked.
Connect the end of the air intake pipe with the wall duct. The
pipe must be fitted with a protective grid so that small animals or
rubble cannot enter it.
m
Adjust the burner air according to the "TECHNICAL DATA"
table.
3.6 CONNECTION TO THE SMOKE OUTLET DUCT
The smoke outlet ducts must be made of steel and in accordance
with EN 1443.
The combustion efficiency and the proper burner operation depend
on the chimney draught. For connection to the chimney pipe, the
applicable legal regulations and the following provisions must be
observed:
• The chimney connection must be as short as possible and
ascending (minimum height 1 m);
• There must be no sharp curves or reductions in cross-section;
• Always provide a wind shield to prevent the penetration of rain
water or clogging of the smoke outlet due to wind;
• The draught of the chimney pipe must not be lower than the
nominal value;
• Every air heater must have its own chimney;
