Part J of the building regulations requires that a heat producing appliance shall have adequate provision for the discharge of the products of combustion to the outside air; and that any heat producing appliance, flue pipe, or chimney shall be designed and constructed so as to reduce to a reasonable level the risk of the building catching fire as a consequence of its use.

Technical guidance document J published by my Department gives guidance on how to comply with Part J. In particular, guidance is given covering the appropriate location of flue terminals for both natural draught and balanced flue appliances, shielding of flue pipes from combustible materials, encasement of flues where passing through compartment walls and floors and the need for provision for flue cleaning.

For additional guidance, reference is made to an Irish Standard IS 813 — domestic gas installations — adopted by the National Standards Authority of Ireland, which deals with the installation of domestic gas appliances generally, including the location of flues and flue terminals.
