1.7 Health and Safety

WARNING

The Oil Fired Cabinet Heater range must be installed in accordance with the current OFTEC regulations for oil

red products Due account should also be taken of any obligations arising from the Health and Safety at Works

Act 1974 or relevant codes of practice. In addition the installation must be carried out in accordance with the

current IEE wiring regulations (BS 7671), BS 6896: (Industrial & Commercial) and any other relevant British

Standards and Codes of Practice by a qualied installer. Isolate all electrical supplies to the heater & controller

before proceeding.

For your own safety we recommend the use of safety boots and leather faced gloves when handling sharp or heavy

items. The use of protective eye wear is also recommended.

CAUTION Before using this appliance:

• Check that the voltage indicated on the type plate corresponds to the mains supply voltage.

• Ensure that the heater has been securely fastened in its nal mountain position.

WARNING

UNDER NO CIRCUMSTANCES should any item be placed on or above any part of the heater, whether the heater

is being used or not. This appliance must be earthed.

1.8 Location / Positioning

WARNING

All of the basic criteria must be satised prior to commencing installation and commissioning, additionally, the

Oil Fired Cabinet Heater must be positioned and installed so as to comply with all the relevant standards and

guide lines (see section 1.1), as well as meeting national and local re regulations and insurance criteria,

especially if it is proposed that the heater is to be installed within a special risk area (e.g. proximity to where

petrol engined vehicles are stored or parked, where cellulose spraying takes place, where woodworking

machinery is operated, etc,).

Indirect heaters must not be located in hazardous areas, however, it is permissible for the heater to supply air to such

areas.

The heater must not be installed within an environment where there is a high concentration of chlorides, uorides,

salts, or other aggressive or volatile chemicals/compounds. Nor should the heater be positioned where the burner

could be adversely affected by high winds or draughts.

The location chosen for the heater must allow for the tting of an effective ue system.

Page 10

The location must also allow for adequate clearance for the air supply, return air circulation, oil supply and electrical

supply, whilst also providing good and safe working access. The heater must be installed on a at and level surface

made from non-combustible material, which is sufciently robust to withstand the weight of the heater and any

ancillary equipment. Any combustible material adjacent to the heater or ue system must be so placed or shielded so

that its surface temperature does not exceed 65°C.

In areas where it is proposed that more than one heater is to be installed, a general scheme of circulation should be

drawn up and maintained, thereby offering the best heat distribution

All Oil Fired Cabinet Heaters are tted with a pressure relief facility, this is incorporated into the design of the ue gas

exit duct.

Care should therefore be taken in siting service connections and controls well away from the pressure relief vent.

WARNING

Under no circumstances must the pressure relief be restricted, blocked, or have the free exit of exhaust gas

impaired or re-directed.

1.9 Fuel supply - general

The Oil Fired Cabinet Heater range are all manufactured and pre-set for use with 35 second gas oil delivered to the

burner via a suitable piped system from the oil storage tank.

WARNING

Galvanised or plastic pipe work and ttings must not be used. (See BS 5410 Part 1 1997)

The constraints of the application will, to a large extent, determine whether it is preferable to use a single pipe gravity

feed system, or whether the two pipe pumped system is more appropriate.

Where more than one appliance is to share a common supply it will be necessary to use a pressurised ring main

system.

All pipe work must be constructed and installed so that it does not permit the ingress of air.

The construction, size, and position of the oil storage tank must take account of the current regulations, as well as

suiting the requirements of the installation.

Please refer to pages 9 and 10 for additional information.

CAUTION

On pumped systems always check that the pump is correctly set up prior to running, and always ensure that

valves are open allowing a free ow of oil through the system.

1.9.1 Fuel

In order to promote trouble free operating it is necessary that the oil within the storage tank and oil line does not fall

below the cold lter plugging point (cfpp), in this country and with class D fuel (also referred to as gas oil). The critical

temperature is -4°C for this summer grade.

The cfpp critical temperature for the winter grade is -12°C. If summer grade fuel is stored for winter use in areas prone

to severe frosts and low temperatures it will be necessary to insulate or even heat the supply tank and pipe work.

The fuel supplier should be contacted prior to installation so that any requirements concerning delivery,

transport, storage and use can be addressed before work commences.

The inlet pump pressure must not exceed a maximum of 0.4 bar, this is because beyond this point gas is liberated

from the oil.
