1.5 Fire Front Location
This fire front can only be fitted to a Glow-worm 45F,
45FR, 56F or 56FR back boiler unit which itself has been
installed in accordance with the Glow-worm Installation
and Servicing Instructions for the back boiler.
Before fitting the fire front it is important to make sure
that the annular space between the back boiler flue liner
and the chimney is sealed at the base and top of the
chimney, as shown in diagram 1.3.
The back boiler air duct acts as a support for the
combustion chamber assembly.
The fire front must be secured to a vertical fire fixing
wall face. This wall face may be a chimney breast or
surround having a minimum flat area as shown in
diagram 1.2.
The combustion chamber flue spigot assembly projects
into the the back boiler flue collector assembly.
The gas supply is taken from the back boiler gas service
cock.
The back boiler must be correctly positioned in the
builder’s opening as the fire front is located by
connection to it.

Restrictions must not be placed around the assembled fire
front, see diagram 1.2.
A shelf or surround of a maximum depth of 150mm may
be fitted, provided clearances are as shown in diagram 1.2.
However, for every 25mm above the fire front the depth
of the shelf may be increased by 25mm.
Combustible furniture or materials must not be placed
closer than 1metre (39in) in front of the fire front.
