Table A - Installation Depth Requirements for a Kohlangaz Delamere gas fire
being installed into a brick built chimney, requiring 12.0 litres of debris
collection volume (fig. 2)
When installing this product into a builders opening / brick-built chimney, the depth
required is a minimum of 170mm. The 12.0 litres of debris collection volume is
achieved by the space available by the taper down the sides and rear of the
firebox. This appliance is suitable for use in fireplaces fitted with an existing chair-
brick without the need for removal of the chairbrick, providing the minimum depth
of the fireplace exceeds 260mm. If the depth is less than 260mm then the spacer
(optional) must be used to give a minimum clearance from the rear of the fire to
the rear of the chairbrick of at least 90mm to allow sufficient space for the
collection of debris which may fall down the chimney. The fireplace must be
checked to ensure that no part of the chairbrick is within 50mm of the flue outlet of
the fire when installed.
For example, if the appliance was to be fitted into a 400mm wide opening (without
a chairbrick), the depth required would be 170mm. See figure 2 below for
explanatory diagram.
