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 1.2.
The combustion chamber flue spigot assembly projects into the
back boiler unit draught diverter assembly.
The gas supply is taken from the fire front gas service cock,
located in front of the back boiler unit.
The back boiler must be correctly positioned in the builder’s
opening as the fire front is located by connection to it.
1.6 Clearances
Restrictions must not be placed around the assembled fire, see
diagram 1.3.
A shelf or surround of a maximum depth of 150mm may be
fitted, provided clearances are as shown in diagram 1.3.
However, for every 25mm extra above the fire the depth of the
shelf may be increased by 25mm.
Combustible furniture or materials must not be placed closer
than 1metre in front of the fire.
1.7 Unpacking
There is one carton containing all parts necessary for fitting of
the fire including draught diverter and blanking plate.
Note: The contents will include either the Chatsworth or Dovedale
fret and ashpit cover.
Check contents of loose items pack against packed list.
Reminder: Overstick new data label over BBU data label, see
diagram 1.1.
2.1 Hearth
In ALL cases a fireproof hearth to the minimum dimensions as
shown in diagram 2.1, must be fitted.
2.2 With Surround
The surround must have a minimum clear flat area as shown in
diagram 1.3. Any projection on the surround must be outside
this area.
Any combustible material, for example, blown vinyl wall covering,
on the fire front fixing face area must be removed to a height of
625mm and 268.5mm each side of the centre line. These
dimensions will allow the standard frame, if fitted, to overlap the
remaining wall covering by 5mm.
This area, to the depth removed should then be rendered with
a sand/cement mixture.
2.3 Without Surround
The fire front fixing wall face must be flat over an area as shown
in diagram 1.3. This also shows the minimum clearances for
shelves or projections on the fire front fixing wall face.
The information regarding the fire front opening must be followed
together with the last three paragraphs of 2.2.“With Surround”.
2.4 Flue and Ventilation
Slide the draught diverter, supplied with the fire, into the draught
diverter body on the BBU and secure with two 5mm dog point
screws, see diagram 3.2.
The draught diverter assembly accepts the combustion flue
assembly.
Note: Provision must have been made during installation of the
back boiler for the total ventilation requirement of the combined
appliance. See the relevant Section in the Back Boiler Installation
and Servicing instructions.
