Installation
CAUTION: It is recommended that fuel be at a temperature of 5 degrees Celsius or higher when it
enters the pump. At a temperature below 5 degrees Celsius oil becomes more viscous and difficult
to pump. Supply of the burner tank may be reduced, resulting in nuisance shutdowns.
The storage tank should be no closer than 1,5m and no farther then 10m from the burner. If the
thank is lower than the boiler and is more then 5m away from burner, then external pump must be
used.
At the bottom of the supply tank manual valve must be installed (for water and sludge separation)
WARNING: Never install suction line at the bottom of the supply tank! Suction line must be fitted at
20cm higher from bottom.
SUPPLY LINES
Read this section carefully before installing any supply lines. Since a suction line leak is nearly
impossible to find,
take your time to assure all connections are leak-free during installation. Supply
lines and fittings are furnished by the installer.
With the vacuum gauge mounted on the pump vacuum port, the gauge will indicate any suction
line restriction, including a dirty filter.
All piping should be protected from possible damage and be rigidly fastened in place in
workmanlike manner.
NOTE: Care must be exercised to ensure leak-free connections.
Flue connection
Important condition for perfect operation of the furnace is a correctly dimensioned flue.
Dimensioning is effected in accordance with DIN 4705 in consideration of DIN 18160 and based on
the boiler and burner outputs.
The effective flue height is counted from burner level.
Select a flue design which minimizes the danger of condensation or of a cold flue inner wall.
For exact adjustment and stabilization of the flue draught we recommend the installation
of a draught limiter.
By this means:
• any draught fluctuations are equalized
• moisture in the flue is largely excluded
• stoppage losses are reduced.
Connection pieces should be introduced
into the flue with a gradient of 30° or 45°
viewed in flow direction.
It is best to provide exhaust gas pipes
with thermal insulation.
Exhaust gas thermometer
For exhaust gas temperature monitoring the heating system should be equipped with an exhaust
gas thermometer.
The higher the exhaust gas temperature, the greater the exhaust gas loss.
Rising exhaust gas temperatures indicate increasing deposits of ash inside of combustion chamber,
that will reduce the degree of combustion efficiency.
In the event of an increasing exhaust gas temperature have the heating installation cleaned (see
picture ) .
