KEROSENE & GAS OIL FUELS (MINERAL OILS)
1. The effect of mineral oils on the skin vary according to the duration of exposure.
2. The lighter fractions also remove the protective grease normally present on the surface of the skin
rendering the skin dry, liable to crack and more prone to damage caused by cuts and abrasions.
3. Skin rashes (oil Acne). Seek immediate medical attention for any rash, wart or sore developing on any part
of the body, particularly the scrotum.
4. Avoid as far as possible any skin contact with mineral oil or with clothing contaminated with mineral oil.
5. Never breath any mineral oil vapours. Do not fire the Burner in the open i.e. out of the Boiler as a miss fire
will cause unburnt oil vapours.
Barrier cream containing lanolin such as Rosalex Antisolv, is highly recommended together with a strict
routine of personal cleansing.
Under no circumstances should mineral oils be taken internally.

1:5.1 BOILER CONTROL THERMOSTAT
The Boiler Control Thermostat is also the ON/OFF switch for the Boiler. To switch the Boiler off, turn the
Thermostat to the 'OFF' position.
The Boiler Control Thermostat controls the water temperature within the Boiler. The recommended Control
Thermostat settings are as follows:
WINTER HEATING & HOT WATER 4
SUMMER HOT WATER ONLY 2
The Boiler Control Thermostat automatically switches the Burner ON and OFF to maintain the selected
temperature. The Burner is lit by an automatic ignition system and therefore there is no pilot flame.
The Boiler should not be operated below 60ºC (Summer position) as this will cause corrosion which will
reduce the life of the Boiler.

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 water circulation through the boiler can be totally or substantially reduced whilst the oil
burner can still fire, the water in the boiler will reach very high or boiling temperatures 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 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.

NB: CARE MUST BE EXERCISED WHEN USING A TOP EXIT OIL TANK AS A NON-RETURN VALVE
(FOOT VALVE) MAY ALREADY BE FITTED.
The use of two non-return valves will cause damage to the fuel pump and will invalidate the warranty.
4:8.5 Deaerator Oil Pipe System
A
n alternative two pipe arrangement can be achieved using a 3K-Oil Loop Deaerator which removes the air
from the oil feed on a single pipe lift. The Burner Pump is piped to the Deaerator, which should be positioned
close to the burner.
A Non-Return Valve is not required in the return line.
The advantage of this system is gained where a two pipe run from the oil supply tank is long or difficult to
achieve. Boulter Buderus 3K Deaerators are available from your merchant.
