CALORIFIER SYSTEM
All Beta engines can be fitted with the calorifier
connections to allow the hot water from the closed fresh
water / antifreeze system to circulate through a calorifier
tank, which in turn heats up domestic water. Calorifier
connections on this range of engine are shown.
1. The big problem with a calorifier is to remove all the
air from the system. If this is not achieved then they
don't work!
2. Try and keep the supply and return pipes either
horizontal or sloping down in a continuous fall
towards the calorifier. This avoids air pockets being
created.
3. Extra care must be taken when first filling the calorifier
circuit system with 50% antifreeze to water solution
as the engine may appear to be full but it soon
disappears into the calorifier pipe work. Run the
engine off load for 10 minutes then check the level as
described in 'Filling The Fresh Water System'. Also
check to see if the pipe going to the calorifier is getting
warm. Top up the water level as required and run for
another ten minutes then repeat.
4. If the water level is steady but no warm water is
getting to the Calorifier then (with engine stopped)
very carefully remove the pressure/filler cap using a
large rag/cloth to protect you hand from scalding. Now
very carefully open the Calorifier bleed valve (see
manufacturers instructions) or if none is provided then
very carefully loosen the jubilee clip securing the
supply pipe to the Calorifier. Air should escape.
Refasten securely when no further bubbles are seen.
5. If the calorifier tank is fitted above the heat exchanger /
header tank then you will need to fit a remote header
tank slightly above the calorifier tank.
CAUTION:
TO AVOID PERSONAL INJURY!
Do not do this when the engine is hot as scalding hot
water may be forced out of the pipe under pressure.
