2.4 PREPARATION OF THE F UE HO E
2.4.1 Mark the position of the centre of the flue on the inner wall.
2.4.2 Cut hole for outer flue pipe. There are two possible methods to achieve
this, either core drill or via hammer and chisel.
2.4.3 To core drill, proceed as follows :-
Drill a pilot hole through the wall, in position as specified in figure 6.
Using a 6” core drill, drill the flue hole.
To Hammer and chisel, proceed as follows :-
Mark the position of the centre of the flue pipe as specified in figure 6.
Mark the position of the hole around this point.
Chisel out the area as marked on the wall.
2.4.4 We then recommend that a cardboard cylinder is placed around the flue
pipe and inserted in the chiselled out hole whilst making good.
NOTE :- If the appliance is to be installed into a building under
construction, it is recommended that a non-corrosive metal
tube of 6” diameter be inserted into the position of the hole.

2.5 INSTA ATION OF THE GAS SUPP Y
2.5.1 Before installing the firebox, decide from which side or if a rear
connection to the gas supply is required. Plan the pipe run to enter the
firebox from the left, right or rear and connect to the inlet elbow. See
below :-
2.5.2 If concealed pipe work is required plan the pipe run to enter the fire box
through the openings in the rear of the fire box and connect to the inlet
elbow. See Fig. 7 & 8 below for a suggested concealed pipe layout.
Fig. 7
Fig. 8
Note : Before breaking into the gas supply a pressure drop test should be
carried out to establish that the existing pipework is sound. Always re-fit the
gas inlet plate to the rear entry point and secure with the screws provided.

2.6 PREPARATION OF THE F UE DUCT
2.6.1 Place the firebox into the fire opening with fire surround correctly
secured in the final position. From the outside of the house measure
from the face of the outside wall to the rear panel of the firebox through
the flue hole. Cut the flue duct to this size.
IMPORTANT : ENSURE THE PIPES ARE CUT SQUARE Y.
2.6.2 The joint between the firebox and the flue duct as shown below in Fig. 9
must be secured with screws and sealed with the foil tape as supplied.
In order to do this, the wall plate must removed from the flue pipe /
termination.
Fig. 9
2.6.3 Due to the varying lengths of flue that will be required via differing
installations it will be necessary to drill the flue pipe using the 3 off holes
in the mounting flange on the rear of the combustion chamber as a
guide for positioning. When the holes have been drilled and the screws
fitted, wrap the joint with the foil tape supplied.
2.6.4 Re-fit the wall plate ensuring the outer set of holes as indicated above
in Fig. 9 are used. Use a high temperature sealant to secure the wall
plate to the outside wall of the property before securing with the screws
and rawlplugs supplied to ensure a mechanical fix.

2.7 SECURING OF FIREBOX TO THE OPENING
2.7.1 There is a choice of methods of fixing the firebox that are provided to
enable the installer to deal with any type of installation. The preferred
method of fixing the appliance is the cable fixing method, which is
described in detail in the following section.
2.7.2 If the standard firebox fixing flange is to be used, the firebox may be
secured using the cable method, but in installations where the cable
method is not suitable, e.g.insufficient space behind the firebox, or
loose masonry, the firebox can be fitted directly to either the front of the
fireplace via the flange with the four off screws provided. The firebox will
require sealing to the fireplace, regardless of the method used.
2.7.3 To secure the fire using the preferred cable method, proceed as follows
below :-
2.7.4 Mark out and drill 4 off No 14 6mm holes in the rear face of the fire
opening in the positions as shown in Fig. 10 below.
Fig. 10
2.7.5 Fit the wall plugs provided and screw the fixing eyes securely into the
rear of the fire opening. Remove the glass frame and burner assembly
as detailed in section 2.10 / 2.11.
2.7.6 Uncoil the two fire fixing cables and thread one end of the each of the
cables through the ears in the top of the fire box lid, and through each
fixing eye at the top. Thread both cables through the fixing eye’s at the
bottom, then the holes at the bottom of the firebox
2.7.7 Thread the cables through the rear of the firebox, insert the flue pipe /
terminal through the hole in the rear of the opening and offer the firebox
up to the fireplace.

2.7.8 Thread a tensioning screw over both of the cables and ensure that the
tensioning nut is screwed fully up against the hexagon shoulder of the
tensioning screw (this provides maximum travel for the tensioning nut).
2.7.9 Fit a screwed nipple on to each of the cables and pull hand tight up
against the tensioning screw, then secure each nipple with a
screwdriver.
2.7.10 Before making the final gas connection, thoroughly purge the gas
supply pipework to remove all foreign matter, otherwise serious
damage may be caused to the gas control valve on the fire.
Failure to purge the gas supply will invalidate the guarantee.
2.8 MAKING THE GAS CONNECTION / PRESSURE TESTING
2.8.1 The gas connection should be made to the appliance inlet elbow to
using 8mm rigid tubing.
2.8.2 Remove the pressure test point screw from the inlet elbow and fit a
manometer.
2.8.3 Turn on the main gas supply and carry out a gas tightness test.
2.8.4 Light the fire (see pages 19-20 for instructions).
2.8.5 Check that the gas pressure is 20.0 mbar (+/- 1.0mbar) 8.0 in w.g.(+/-
0.4 in w.g.). Turn off the fire, remove the manometer and refit the
pressure test point screw. Check the pressure test point screw for gas
tightness with the appliance turned on using a suitable leak detection
fluid or detector.
2.9 FITTING THE TERMINA GUARD
2.9.1 With the flue terminal in position, place the terminal guard over the top
of the flue terminal and mark the position of the holes on the outer wall.
2.9.2 Remove the terminal guard and drill the 4 off 6 mm holes.
2.9.3 Insert the raw plugs into the drilled holes, replace the terminal guard
over the top of the flue terminal and attach to the wall using the No.12 x
40mm screws provided with the terminal guard.
NOTE : In England & Wales, building regulations require that a terminal
guard should be fitted if the terminal could come into contact with
people near the building or be subject to damage. BFM Europe
td. also recommend the fitting of a flue terminal guard where
regulations do not demand that it be fitted. A suitable flue terminal
guard is supplied with the appliance.
