5. HEATER COMPARTMENT AND CLEARANCES (See BS 5864)
5.1 IMPORTANT: If the heater is to be fitted to an existing base duct (warm air plenum), always ensure that installation
is carried out such that the rear left hand corner of the heater is aligned with the rear left hand corner of the base duct,
so that any overhang or blanking off will be at the front and/or right hand side. In any event, blanking plates must be
mechanically secured and all joints sealed.
5.2 When the heater is fitted into a compartment, a minimum clearance from the compartment walls of 3mm (
1
/
8
”) at the
sides and rear and 75mm (3”) at the front must be left. Consideration should also be given to the space required for
the removal and replacement of the filter tray and the entry of the gas, water and electrical supplies. If gas and /or water
connections are made from a side entry, a minimum clearance of 75mm (3”) is required at that side.
5.3 For service access, a minimum of 450mm (18”) is required at the front of the heater. Space must also be allowed, in a
compartment installation, to permit the removal of the heater. The clearance between the appliance and the compartment
should be not less than 75mm (3”). However, if clearances are less than 75mm, the internal surface of the compartment
must be lined with non-combustible material and the compartment must be of a fixed rigid structure.
5.4 In airing cupboard installations, the part used as the air heater compartment must comply with the relevant section of
BS 5864 and must be completely separated by either a non-combustible partition or a perforated metal partition with the
perforations not exceeding 13mm (½”). The secondary flue must be a tight fit where it passes through the partition and
must be suitably protected (see BS 5440: Part 1).
