1.2. Fire Fret Dimensions
All the Custom 18 Plus range of fires are designed such that they can be installed in fireplace
furniture, e.g. fire baskets, swans nests, etc. There must be an all round clearance of at least
25mm (1”) between the outside edges of the fireplace furniture and the walls of the fireplace
opening. In addition, there must be a minimum free air opening in the fireplace furniture as
indicated in the diagram below.

NOTE:
The free air required through the ash pan door is only required if the
fireplace furniture is enclosed at the sides and to the rear. If this is not the case,
e.g. freestanding basket, then the free air through the ash pan cover is no longer
required, and a solid ash pan cover may be used.
NOTE:
: any relevant grate bars will need removing for the fire to fit into the
fireplace opening
