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.

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 combustion chamber assembly is designed to fit into
a standard builder’s opening as shown in diagram 2.2.

A wider opening will require to be reduced in width
using non-combustible materials.

The surround must have a minimum clear flat area as
shown in diagram 1.2. 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 of the
surround must be removed, see diagram 2.3.

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 1.2. This also shows the minimum
clearances for shelves or projections on the fire front
fixing wall face.

The fire front is delivered in two packs, one contains the
combustion chamber assembly, fuel pack(s) and loose
items pack. The other contains the fire front, fret, ash pit
cover and fire control knob extension.

Refer to diagram 3.1 to identify the parts.
Check contents of loose items pack against packed list.

3.2 Gas Supply to Fire Front

Check that the gas service cock is in the boiler only on
position, see diagram 3.2.

The inlet supply tube is packed with the loose items.
The supply tube may need to be cut at the larger end

dependent upon the position of the back boiler unit in the
opening.

Measure the distance “C”, see diagram 3.3, from the
front mark “P” on the air duct to the fire fixing wall face.

Use a straight edge across the opening.
Shorten the gas supply tube by distance “C” + 21mm at

the larger end.
The maximum distance for “C” will be 25mm (1inch).
Deburr the tube end inside and out.

4.1 Positioning the Combustion Chamber
Assembly

Note: Before fitting, again make sure the wall surface to
which the combustion chamber assembly is to be fitted is
vertical and flat. Any unevenness may cause the whole
assembly to become twisted or distorted when fixing to
the wall.

Place the combustion chamber assembly into the fire
opening and make sure that the flue spigot fits into the
boiler flue collector assembly and locates onto the back
boiler combustion chamber extension and burner
assembly, see diagram 4.1.

Push well back to the fire fixing wall face.
Mark the four combustion chamber assembly fixing

points (making sure that the area is sufficiently firm),
through the holes in the surround refer to diagram 4.2.

Pull the combustion chamber assembly forwards and
remove.

Drill the fire front fixing wall face, using a 10mm
masonry drill to a minimum depth of 40mm to accept the
reusable anchor nuts and screws provided.

Note. If the fire front fixing wall face is not of a solid

construction to a minimum depth of 40mm, for example,
hollow brick or metal an alternative and rigid form of
fastening for the combustion chamber assembly must be
used and extra care taken.

Fit the combustion chamber assembly, making sure that
it is correctly positioned onto the back boiler unit, see
diagram 4.1, secure with the screws provided.

Important: If the electrical supply to the boiler comes
from the right, make sure that when fitting the
combustion chamber assembly the cable is routed and
clear, as shown in diagram 4.1.

5.1 Lighting and Testing

Make sure that the gas tap is in the off position, that is,
the flat on the drive rod faces the wall, see diagram 5.1.
Take the length of black insulating material from the
loose items pack. Slide the insulation down the drive
rod as shown in diagram 5.1 and then fit the control
knob.

MAKE SURE THAT THE ELECTRICAL SUPPLY TO
THE BACK BOILER IS SWITCHED OFF.

Take the ash pit cover from the packing, make sure that
the harness strain relief is fully located into the slot and
that the locknut is tightened.

Now fit the strain relief bracket by removing the burner
fixing screw, place the strain relief bracket on top of
burner end bracket and then replace screw, see
diagram 4.3.

Connect the wiring harness to the microswitch and
electrode, see diagram 7.3 and 7.4.

Fit the battery, from the loose items pack, see
diagram 9.1.

Note the ash pit cover can be left connected up to the
micro switch and tap.

Remove the pressure test nipple screw and fit a suitable
pressure gauge, see diagram 5.2.

Turn the gas service cock to BACK BOILER AND
FIRE “ON”, see diagram 3.2.

To check for gas soundness apply leak detection fluid to
the two joints on the previously fitted gas supply tube.

WARNING: Take care when carrying out the following
check, as the burner flame is fully exposed.

Push the control knob in slightly and turn it
anti-clockwise to position I , now fully push in,
clicking of the ignition will be heard and the burner will

light.
IMPORTANT: If the burner does not light within 3

seconds, release the tap, wait 10 seconds and repeat the
lighting operation.

Keep the knob pushed in for 10 seconds, during this time
the ignition system will continue to operate, indicated by
the clicking.
