3.1 Unpacking
The fire front is delivered in two packs, one contains the body
assembly, fuel effect pieces and supply tube pack.
The other contains the fire front castings, side panels, plinth and
loose items pack. Refer to diagram 3.1. to identify the parts.
To unpack carton 1, lift out the top fitting containing the fire
spigot and combustion chamber bottom plate, lift out the
cardboard front fitting, the supply tube pack and the two boxes
containing the fuel effect pieces.
Lift the outer carton clear to leave the fire front sitting in the base
tray.
To unpack carton 2, lift out the cardboard tray containing the
plinth and side panels. Lift out the loose items pack, legs box
and canopy. Remove the internal cardboard fitting and lift out
the lower front and side castings.
Put these items on one side until required. Check contents of
loose items pack against list.
Remove the glass front panel, see diagram 3.3.
It is suggested that the side extensions, from the castings pack,
be fitted at this time to the left and right hand side panels.
NOTE: These are a slide fit onto the louvres.
3.2 Flue Spigot Assembly
Note. This is marked “Homeglow BBU”
Leave the fire front sitting in the base tray.
Remove the two plastic transit studs securing the wall sealing
plate to the rear of the fire front and put it on one side until
required.
Secure the spigot assembly to the fire front back with the self
taping screws provided, in the loose items pack, see diagram
3.4.
Note. There are eight self tapping screws in the pack, one
spare.
3.3 Gas Supply Tube and Sensing Tubes
Preparation
Remove the plastic ferrule from the bulkhead connector on the
air duct and discard.
Fix the flared end of the back boiler sensing tube to the bulkhead
connection on the boiler air duct with the tubing nut provided.
Slide the sensing tube mounting bracket assembly over the
back boiler sensing tube and fix to the casing with the screw
provided, see diagram 4.1. Fit the sensing tube filter onto the
fitting assembly, see diagram 4.1. Take care not to damage the
filter.
Important. Make sure that the mounting bracket assembly is
pushed back to the fire front face of the boiler casting and check
3mm distance is achieved and the back boiler sensing tube
does not extend above the sensing tube bracket assembly, see
diagram 4.1.
Note. After fitting the flue blockage safety device sensing tube
please refer to the 'commisioning' section of the back boiler unit
and relight the boiler to test the device.
Check that the gas service cock is in the Off position, see
diagram 3.5.
The inlet supply tube, back boiler sensing tube assembly and
fire front sensing tube are packed in the supply tube pack, see
diagram 3.2.
This supply tube and fire front sensing tube may need to be cut,
at the plain end, dependent on the model and position of the
back boiler in the opening.

Gas Supply Tube
Measure the distance “C”, see diagram 3.6, from the front mark
“P” on the air duct to the fire front fixing wall face.
Use a straight edge across the opening.
Shorten the plain end of the gas supply tube by the distance “C”.
No shortening is required when mark “P” is level with the fire
front fixing wall face, “C” being zero.
The maximum distance for “C” will be 67mm (2

/
8
in).
