ABOUT LPG
The properties of LPG
LPG is a petroleum product, formally
known as "liquid petroleum gas". It is
mainly made up of propane and butane
gas. The advantage of propane is that it
remains gaseous at temperatures as low
as -40°F/-40°C, while butane loses effec-
tiveness at 50°F/+10°C. For this reason,
propane is used in colder countries.
The cylinders contain LPG both in liquid
and gaseous form. When the cylinders
are filled, the pressure turns the gas into
liquid. When the cylinder valve is opened,
the LPG becomes a gas again.
The risk involved in using LPG is that any
leaking gas may ignite and explode. Since
LPG is heavier than air, any leaking gas
will collect at the lowest point.
LPG contains no toxic substances, but
breathing in concentrated gas may have a
certain anaesthetising effect, and can also
result in shortness of breath and symp-
toms of suffocation. These symptoms
quickly disappear if the sufferer breathes
in ordinary air or oxygen.
Naturally, it is inadvisable to inhale either
LPG or exhaust fumes. To make it easier
to detect gas leaks, a substance with a
distinctly rank smell has been added.
Combustion
Complete combustion of LPG only gen-
erates carbon dioxide (CO2) and water
vapour, just like the air we exhale. A
good supply of air is essential to ensure
complete combustion. The flame should
burn with a weak blue colour, the centre
of the flame should be blue/green. LPG is
extremely environmentally compatible and
does not generate any soot during com-
plete combustion. It can be stored in cylin-
ders for an unlimited time period, without
any deterioration of quality.
Pressure
The LPG burner usually works at a lower
pressure than that in the cylinder. Low
pressure (0-0.75psi/0-50 mbar) and inter-
mediate pressure (0.75-30psi/50 mbar-2.0
bar) are created by allowing the gas to
pass through a reduction valve. High pres-
sure (over 30psi/2.0 bar), is unreduced
pressure mainly used in camping equip-
ment. Low pressure and intermediate
pressure are always reduced pressure.
TROUBLESHOOTING
If the boiler is equipped with a digital con-
trol panel, always start by checking any
error messages.
The boiler does not start on gas:
1. No LPG? Incorrect type for conditions?
2. Is the main tap fully open?
3. Check that a suitable type of LPG is
used for the prevailing outdoor
temperature. Using butane is unsuit-
able at temperatures lower than
50°F/+10°C. Use propane instead!
4. If the boiler has not been operated for
some time, or if the gas cylinder has
been changed, it may take longer than
normal to light the boiler.
5. Check that the boiler is connected to
the electricity supply (> 11 V).
6. Check that the fuse for the boiler is
intact.
7. Check whether the electric connections
on the boiler are securely in position.
8. If none of the above helps, contact a
service workshop.
The heating element is not work-
ing:
1. Check that there is an electricity supply
(120 V ~) to the heating element.
2. Check that the relays fitted to the boiler
come on (a slight click can be heard
from the relays when the heating ele-
ment is switched on at the control
panel).
If none of the above helps, contact a ser-
vice workshop.
Emergency start and operation:
1. Disconnect 12V and the cable to the
panel on the heater.
2. Connect a cable between 2 and 9 in
the contact device (on the heater).
3. Connect 12V to the heater.
4. Now the heater starts with gas and
1kW. (Regulation of room tempera-
ture does not function, constant pump
operation).
