11-3.1 Cold Fill Pressure
Check the cold fill pressure is as recorded, reset the red pointer if required.
A drop in the cold fill pressure indicates that the system requires topping up. If regular
topping up is required it indicates that there may be a leak in the system. Refer to 6-2.2.
11-3.2 TPR Valve
Check as detailed in 6-2.5.

Baffle Positions
Baffles are fitted in the heat exchanger of Boilers, they provide optimum heat distribution
to maintain the Boiler efficiency.
When baffles are left out, wrongly positioned or excessively distorted, the Boiler
efficiency will be drastically reduced.
Baffles should be removed, cleaned and replaced during routine servicing.
Care should be taken when replacing baffles to ensure that they are correctly fitted. Fig.
11-4a shows the right and wrong way of fitting some baffles.
IMPORTANT
All baffles must be fitted.
All baffles must be correctly positioned.
Replace distorted baffles.
If baffles appear to be missing check they have not fallen to the bottom of
the heat exchanger during transit.
