Värmebaronen Vedolux -350, -450 and -650
Check regularly that the heating system is
in good condition, that there is sufficient
water in the system and that there are no
leaks.
Ceramics - grate
The boiler’s ceramic parts and grate are wearing
parts that need replacement as required.
Wearing parts are not covered by any warranty.
Small cracks in the ceramics are normal and require
no action.
To increase the service life, remember the following:
• Do not remove the ceramics when cleaning the
combustion chamber.
• Leave an ash layer of a few centimetres to protect
the ceramics. Pieces of charred wood can remain.
Rake surplus ash down through the grate.
• Scrape the ceramics carefully when removing ash.
• Fire only with real wood, not plastic, processed
timber, refuse or similar.
• The wood must be inserted in the boiler, not thrown.
• If the boiler/ceramics is/are new or has/have
not been used for a while, the ceramics must be
warmed with a small fire.

Venting/filling
Check regularly that there is sufficient
water in the heating system.
Air may be left in the heating system for a while after
installation, for which reason it should be vented
a few more times. Check the pressure after venting
and add water if necessary.
Water changes its volume with temperature, which
affects the pressure in the heating system. Higher
temperature produces higher volume and pressure.
The expansion tank absorbs the volume changes
in the system.
The pressure in a heating system varies
with the temperature. Do not add water
unnecessarily.
Safety valves
Safety valves must be activated regularly to maintain
the safety function.
Open the valve manually and check that water flows
out and that the valve subsequently closes tight.
Closed expansion system
The prepressurisation of a closed expansion system
should be checked every year or two. The tank may
then not be subject to any pressure from the heating
system.
Max. temperature thermal
relay, STB
Remove the plastic plug
and press in a narrow
object
to reset
the max.
temperature
thermal relay.
When it is reset,
the boiler temperature
must be lower than
185°F.
Call an installation engineer if the max.
temperature thermal relay trips repeatedly.
