Cooling - Calorifier Connections - Beta Marine BetaSet 7 Installation Manual

CALORIFIER CONNECTIONS
Generating Set engines can be fitted with optional
calorifier connections so that the engine coolant circuit is
allowed to flow through a calorifier tank to heat water
for domestic use. Typical calorifier circuits and connection
locations for heat exchanger & keel cooled generating sets
are shown below. When installing please note:
1. For a calorifier to operate it is essential for all the air to
be removed from the system.
2. If the calorifier tank or pipework is fitted above the
heat exchanger or header tank (keel cooled) then you
will need to fit a remote header tank slightly above
the calorifier tank.
3. Keep the supply pipe either horizontal or sloping down
in a continuous fall towards the calorifier. The return
pipe should also be either horizontal or sloping down
in a continuous fall towards the engine to avoid air
pockets being created.
4. Extra care must be taken when first connecting the
calorifier system to the engine as the coolant level in

the heat exchanger or header tank (keel cooled) will
drop as the circuit is filled. Once connected fill the
coolant level as described in 'Filling The Fresh Water
System' then run the engine off load for 10 minutes.
Allow to cool to a safe temperature, then re-check the
level and top up as necessary. Check the calorifier feed
pipe to see if it is starting to warm. Run the engine for
another ten minutes then repeat this process until the
coolant level remains stable.
5. If the coolant level is steady but no warm water is
arriving into the calorifier then (stop the engine and
once suitably cooled down) using appropriate personal
protective equipment carefully remove the heat
exchanger or header tank (keel cooled) pressure/filler
cap. Refer to the calorifier manufacturers instructions,
then open the calorifier bleed valve and allow all air to
escape before refastening. If no bleed valve is provided
loosen the clip which secures the supply pipe to the
calorifier and allow all air to escape before refastening.
Repeat step 4.
