Carbery Plastics

1. Test the cistern before installation as it may have been damaged in transit.
2. The base shall be adequately and uniformly supported over its whole area.
3. A hole cutting tool should be used to ensure a circular hole free from notches.
4. Do not use heated metal tubing.
5. Always support the cistern wall whilst drilling.
6. Puipes should be supported and aligned so as not to distort the cistern.
7. Back nuts should not be over tightened
8. Cisterns arranged to receive expansion water shall be fitted internally and externally at all outlet connections with suitably protected washer plates. WARNING: For sealing connectors, use PTFE tape. Under no circumstances use jointing compounds or putty in contact with the cistern.
9. The centre of the ball-valve shall be 38mm from the top of the cistern.
10. The cistern should be positioned that it is not in close proximity to heaters, light bulbs or other sources of heat.

Carbery Oil Tanks are suitable only for the storage of:

Kerosene (C1/C2)
Agricultural Fuel Oil (A2)
Diesel (D)
Home Heating Oil
BioDiesel blends manufactured in accordance with the requirements of British Standard BS EN14214 / Irish Standard IS EN14214 not greater than B5 i.e. BioDiesel with a bio-element not exceeding 5% concentration

All Carbery Oil Tanks must be installed in accordance with supplied instructions, the requirements of OFTEC Technical Instruction Book 3 and prevailing statutory requirements. Please note that Carbery Heating Oil Tanks are not suitable for connection to a fuel delivery system incorporating a flexible hose and automatic trigger nozzle.

A single skin oil tank is a tank of single wall (skin) construction in which fuel is stored. These were initially the tank of choice for most installations / applications, however recent changes in regulations have instructed that single skin oil tanks can not be used for FUEL storage in the following conditions:

• Commercial / Industrial Applications
• Institutional Application
• Domestic installations where the installed capacity exceeds 2500L (unless suitably bunded – see Bunded Oil Tanks)

It is highly likely that in the foreseeable future, driven with environmental impact considerations in mind, that regulations will change to insist on Bunded Oil Tanks. Therefore careful consideration should be given to this when selecting an oil tank.

Also worth mentioning is the fact that Property Insurance Premiums may be affected by the type of tank installed.

A Bunded Oil Tank is a tank which is inside a tank. This ‘tank in a tank’ construction is also referred to as an integrally bunded tank. The outer tank is referred to as the bund and is required to hold at least 110% of the inner tanks brimful volume. Bunded oil tanks are required to be used for FUEL storage in the following conditions:

• Commercial / Industrial Applications
• Institutional Application
• Domestic installations where the installed capacity exceeds 2500L (unless suitably bunded – see Bunded Oil Tanks)
• Any Installation with a environmentally sensitive application as dictated by required

Bunded oil tanks offer protection from end of life failure of inner tank and overfilling of the tank during use; in the event of either of these conditions an alarm with sound and display light up warning that there is oil in the outer tank (bund). This warning gives the customer time to change out the tank or empty the overfilled oil without causing an environmental situation.

If the tank is less than 3500 litres, it should not be placed within 760mm of a combustible boundary e.g. a fence.

This distance assumes that there are no flu outlets or buildings between the tank and the boundary. Where these clearances cannot be achieved, the protection measures noted in British Standard BS 5410: Part 1: 1997 must be provided, by means of a 30 minutes fire-resistant wall - which extends at least 300mm above and beyond the ends of the tank.

For tanks with a capacity greater than 3500 litres of for fire barrier construction requirements, please contact OFTEC for advice.

Oil Tanks with a capacity of less than 3,500 litres should not be placed within 1.8 metres of a flu outlet.

Where these clearances cannot be achieved, the protection measures noted in British Standard BS 5410: Part 1: 1997 must be provided by means of a 30 minutes fire-resistant wall which extends at least 300mm above and beyond the ends of the tank.

For oil tanks with a capacity over 3,500 litres or advice on constructing a fire resistant barrier, please contact OFTEC.

Oil Tanks with a capacity not greater 3,500 litres should not be fitted any closer than 1.8 metres to non-fire rated (30 mins. minimum) walls or eaves.

Where these clearances cannot be achieved, the protection measures noted in British Standard BS 5410: Part 1: 1997 must be provided by means of a 30 minutes fire-resistant wall which extends at least 300mm above and beyond the ends of the tank.

It will be necessary to protect exposed eaves forming part of a roof within 1.8 metres of the top of an oil storage tank to provide a 30 minute resistance to fire. Cladding can be applied to the eaves in order to prevent fire spreading to the roof.

If the tank capacity is greater than 3500 litres or you require further advice, please contact OFTEC.

Internal Oil Tanks should never be installed in a habitable area, and should always be contained within a specially constructed, purpose designed, enclosed chamber. Detailed requirements exist for the installation of oil storage tanks within habitable buildings and domestic garages. For more information, contact OFTEC.

Standard above ground tanks cannot be installed underground directly.

Above ground tanks may be installed underground where a specifically designed load bearing chamber / retaining wall is installed in an area with sufficiently low ground water all of which is certified and performed by a suitably qualified Structural or Civil Engineer.

Carbery has a specifically designed range of Underground Tanks available, however these are not compatible for the storage of heating oil.

Carbery Oil Tanks are manufactured from Medium Density Polyethylene (MDPE) - a material that displays excellent chemical and impact resistance qualities. All Carbery Oil Tanks are manufactured only from premium grade, virgin materials.

Fittings vary according to tank type and market – for more information, please download the appropriate brochure for your market or contact your local Carbery reseller.

All materials and components used in the manufacture of Carbery Oil Tanks are resistant to the potentially damaging effects of the liquids they are designed to contain.
