Part F Section III Scotland
Part L Northern Ireland
The Control of Pollution (Oil) Regulations Oil boilers should be installed in accordance with good practice as
recommended by OFTEC (Ref. 2:3 Commissioning page 6).
4:2 THE HEATING SYSTEM
This should be installed in accordance with current good practice as advised by HVCA. It is not the purpose of
the manual, nor is it possible, to adequately deal with the subject in this manual. When designing and
installing the controls of the heating system, it must be remembered that if the control system is such that the
wate
r
circulation through the boiler can be totally or substantially reduced whilst the oil burner can still fire, the
wate
r
in the boiler will reach very high or boiling temperature before the boiler thermostat can sense it and
switch off the Burner.
If this condition is likely wire the controls so that the electrical supply to the burner is switched off
simultaneously with the stopping of circulating pumps or the closing of motorised valves.
On existing heating systems where a Boiler is replaced, ensure that the system is chemically cleaned.
The system should contain clean water and be free from leaks. Suitable inhibitors against limescale and
corrosion should be added to the system. Refer to BS 7593.
Kettling and system noises can be avoided by suitable pre-treatment (i.e. Chemical Cleaning) at the onset.
This is essential when fitting a new boiler to an existing system.
4:3 SITING & POSITIONING
The noise level from Camray boilers is quite low and kitchen installations have not given rise to complaints.
