EXAMINATION, MAINTENANCE AND SERVICE
EXAMINATION
Check regularly especially, if the combustion in the
burner is different, that
1. the heater gets current.
2. the combustion air access is clear; f. ex.
spiders, mosquitoes, snow, water or ice
can block the air flow.
3. the exhaust outlet is clear.
4. the fuel hose does not leak.
5. there aren’t any impurities or water on the
bottom of the fuel tank.
6. the fuel filter is clean.
7. the air hose of the tank is clear.
8. there isn’t any dust inside the heater; it
may cause smells and risk of fire.
If the heater doesn’t seem to get enough fuel (the
power is lower, the combustion is different),
measure the fuel inlet: Remove the fuel filter (it
may cause measurement errors). When the
heater operates normally on maximum power, put
the fuel hose into a measuring glass with a certain
amount of fuel in it. Let the heater operate for 6
minutes. Multiply the amount of fuel consumed by
10, and you will get the fuel inlet/hour.
On maximum power the
3600D
i heater consumes
340-380ml/h,
3200Di
heater 300–340 ml/h,
2600Di
, heater 240-280ml/h and the
2400Di
heater 220–260 ml/h.
If the measured fuel consumption is above these
limits, check the cause: the tank (or the measuring
glass) may be placed above the heater, or the
default settings of the pump have been changed
and the pumps pulsation is too frequent. The
normal pulsation on maximum power with the
3600Di
heater is180 pulses/min and 50 pulses/min
on minimum power
3200Di
heater is 160
pulses/min and 50 pulses/min on minimum power
2600D
i heater is 130 pulses/min and 50
pulses/min on minimum power, with the
2400Di
heater 120 pulses/min on maximum power and 50
pulses/min on minimum power.
If the heater gets too much fuel, the combustion
may be impure and cause risk of overheating. If
the overheating is caused by defective electronics
or pump, always contact your nearest
maintenance service.
If the fuel consumption is too low, there might be a
blockage in the fuel system. If the filter is clean,
check the fuel hose: the fuel in it may be clouded,
if the hose has been in a cold place for a long
time. If the blockage is not thorough, you can
dissolve it rather quickly with isopropanol
(= common anti-freeze for gasoline engines).
You may also force isopropanol into the hose
when the pump operates (during start) f. ex. with
a hypodermic syringe or bicycle pump.
Also a little leak in the suction hose (before the
pump) may cause the low fuel consumption.
Check if there is a significant amount of bubbles in
the hose. With extensive usage also the fuel inlet
pipe near the burner may be blocked. If this
happens, change the pipe or clean it f. ex. by
heating it with a gas flame and blowing by
compressed air it empty.
WINTER
Remove the battery wire for winter.
If the heater is unused in a cold place for a long
time, the fuel in the hoses and in the tank may
become clouded (this may happen also with winter
grade fuel oil). The last time you use the heater
before the winter, use paraffin oil to avoid starting
problems in the spring. Make sure that paraffin oil
fills the fuel hose, the pump and the fuel filter. In
the spring it’s best to acquire new fuel.
