Calorifier Connection - Beta Marine Beta 50 Operator's Maintenance Manual

CALORIFIER SYSTEM
All Beta engines can be fitted with the calorifier
connections to allow the coolant from the closed circuit
cooling system to circulate through a calorifier tank, which
in turn heats up domestic water. Calorifier connections on
this range of engine are shown.
1. For a calorifier to operate it is essential for all the air
to be removed from the system.
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 connecting the
calorifier circuit system to the engine as the coolant
level in the heat exchanger 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 or pipework 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.
