NOTICE
If the heating system has not been in operation for a long time, or if the gas tank has been replaced,
it may take longer than normal to start the boiler.
Boiler will not start on gas (Gas Failure)
• Run out of LPG?
• Is the main tap fully open?
• Check that the right LPG type is used for the prevailing outdoor temperature.
Using butane at temperatures below +10 °C is unsuitable. Use propane.
• Check that the fuse for the boiler is intact.
• Check that there is a 12 V electricity supply to the boiler (> 11 V); the actual voltage can be read
from the service menu.
• Check that the exhaust hose is firmly mounted between the boiler and flue, and that it is not dam-
aged or clogged by foreign objects, condensation or water.
The exhaust hose consists of two hoses, one inner and one outer.
• Check that there is nothing clogging/obstructing the passage of exhaust to the flue.
• Check that the gas pressure is correct. This can be done by lighting all the burners on the gas stove,
then starting the boiler on gas. If the flames on the stove get smaller, there is a problem with the gas
pressure.
• If the boiler has not been used for some time, or if the gas bottle is new, it can take a little longer
to light the boiler than normal. Try starting the boiler.
• Check any installed hose line with hose rupture protection.
• If DuoControl/MonoControl with Crash sensor are installed, check that they have not tripped out
If none of the above help, contact Alde.
WARNING WARNING
WARNING
VARNING VARNING
Fire/explosion risk
A 230 V power supply carries a risk of electrical accidents. Never attempt to service electric cartridges yourself.
Electric heater will not work satisfactorily
• Check that the fuse for the boiler is intact.
• Check that there is a 12 V electricity supply to the boiler (> 11 V); the actual voltage can be read from
the service menu.
• Check that 230 V is really being supplied to the boiler. Long and/or weak connection cables cause
higher voltage drops and the voltage can sometimes be lower under certain conditions.
• Check that the selected power level on the panel is high enough, see section 11. Starting the heat-
ing system for the first time.
• If fitted, check load sensor (optional) is correctly installed.
If none of the above help, contact Alde.
Poor or no heat (circulation in the heating system)
• Check that the circulation pump symbol is visible on the status screen when heating is needed.
• Check that the circulation pumps are working.
• Check that the heating system is vented.
