22 FLUE TERMINATION

The height and termination of the flue is an important

part of the installation and consideration needs to be

made to ensure that the flue is high enough to create

sufficient draft to clear the products of combustion. The

termination of the flue outlet position which can meet the

requirements in common circumstances are shown in

Document J. If there are unusual circumstances that will

affect the efficient and safe removal of the products of

combustion; the height and/or the separation distances

shown in Document J may need to be increased. A

special cowl may need to be fitted.

23 PROVISION OF A NOTICE PLATE

A notice plate must be durable and be fixed on site, where a hearth, fireplace flue or chimney is provided or extended

(including cases where a flue is provided as part of refurbishment work). ADJ states that the responsibility for

achieving compliance with the requirements of Part J rests with the person carrying out the work and so this person

must be competent in the work they are being asked to do. The completed flue must pass the appropriate tests that

assess whether the flue in the chimney, the connecting flue pipe (and flue gas passages in the appliance) are free of

obstruction and acceptably gas tight. In addition, appliance performance tests, including flue spillage tests should be

carried out when an appliance is commissioned.

24 SITING THE APPLIANCE

This appliance must not be fitted into a location where it will be impossible to service. The location must comply with

the requirements laid down in the Building Regulations.

25 HEARTH REQUIREMENTS

It is essential that the hearth / base on which the appliance will stand is strong enough to support the weight of the

appliance and the chimney / flue. In certain circumstances, it may be necessary to support the flue pipe with brackets.

The hearth must be level and made of a suitably robust, non combustible material.

The positioning of the appliance and dimensions of the hearth must comply with current building regulations.

Manufacturer’s instructions relating to clearances must be adhered to.

26 STOVE CLEARANCES

STOVE CLEARANCES TO FLAMMABLE MATERIALS (SEE FIG. 4A below)

• The minimum distance from any flammable object, or one that is sensitive to heat, (furniture, wood, fabrics. etc.)

and from materials with flammable structure, must be 200 mm to the rear and 200 mm both sides.

• In front of the appliance there must be no flammable object or material, sensitive to heat within 1000mm.

• Above the appliance, there must not be any flammable items within 700mm.
