3.5 Inlet / Outlet Grille Installation
If a fly screen is fitted it should be removed from both the internal and
external grille.
When installing the internal grille, the louvres must slant
upwards to ensure the correct air circulation and the avoidance of
unpleasant down draughts. The outside wall input grille louvres
must slant downwards.
Standard 100mm diameter ducting or 121 x 60mm ducting is used to
connect the Flatmaster to the input and discharge grilles.
Any air intake terminal MUST be installed in accordance with the
appropriate regulation.
As a guide, the BS5440 series of British Standards deals with this
issue and currently states that an air intake must be at a minimum
distance of 300mm from a gas boiler balanced flue. Installers are
advised to be aware of the requirements of this standard when
installing ‘through the wall’ supply air ducting. Similarly, supply
and extract air grilles should be at least 300mm apart.
The internal grille must not be placed within 1.5m of a smoke
alarm.
4.0 DIMENSIONS(mm)
Dimensions for the space required can be determined from the
dimensions shown in Figure 10 below.
Allow an additional 32mm for the length of each end spigot and any
additional room for installation and maintenance e.g. access to screws
on top and bottom of unit for front cover.
