14.4 - FITTING THE FIREBOX & USING THE CABLE FIXING SYSTEM
Reference should be made to the illustrations below.
a.
There is silicone sponge sealing strip already affixed to the relevant surfaces to ensure a good seal. Ensure this silicone sealing
strip stays in place during installation.
b.
A cable fixing system is supplied to secure the unit into the Builders Opening. The cable fixing system will also pull the unit tight
back against the slips to make a good seal. This is very important to ensure efficient operation of the fire.
c.
There are 2 cables supplied; 1 to be used each side of the unit. Working at 510mm centres in the builders opening drill the lower
holes 20mm up from the base and drill the higher holes 460mm up from the base - see drawing on below. Secure the 4 Eyebolts
supplied with the Rawlplugs to the back of the fireplace. Ensure the Eyebolts are fully screwed in.
d.
There are 2 cable attachment point tabs on the top of the main casing; 1 each side at the rear. They are part of the folded lip of the
top section prize these up with a screwdriver to enable them to be used. Feed a cable downwards through the hole in the tab.
e.
Taking care to not damage the slips, rest the Fire in the builders opening so that you can still gain access to the cables and
eyebolts. Feed the cables though the eyebolts on either side and then through the hole in the back of the fire near the base
f.
Slide the Fire
part way
into the Builders Opening
(leaving it sticking out approximately 50mm) ensuring the gas supply pipe and
isolation/pressure test elbow clears through the cut out in the rear of the Main Casing and does not foul on the control.
g.
Lift the Fire slightly and slide it home ensuring that the sealing strips on the underside of the front of the Fire and the rear of the Fire
outer frame stay in position to make a seal against the top edge of the slip at the base of the builders opening and the front face of
the slips where they locate against the rear of the Fire outer frame. While sliding the unit into the Builders Opening pull on the
excess cable.
h.
Referring to the illustrations below feed the cables through the two loose cable clamp brackets. The adjuster and lock screw can
now be fitted onto the cable and through the large hole in the cable clamp bracket. Position the brackets one either side of the fire
towards the bottom of the channel between the Main Casing and the Inner Fire Casing. By use of the adjuster and lock screw
tighten up the cable to tension the fire back into the fireplace. The fire should be secure and not liable to movement.
Surplus fixing cable MUST NOT be cut off and must be tucked back through the small hole in the cable clamp bracket to keep it
well away from any electronics.
i.
If any of the silicone sealing strips are not compressed and/or if there are gaps they must be filled with a suitable sealant, fireclay or
high temperature silicone.
j.
Refit the burner mounting plate assembly by first putting the Receiver through the opening then tilt the assembly and slide it into
the fire and secure with the 4 screws. Take care not to mark the liners in the fire. Place the Receiver to the left side at the front.
l.
Connect the isolation/pressure test elbow to the control valve and with it fully open check the joint for gas soundness.
m.
Check that all gas connections are sound. The appliance has been factory tested; however the connections may have been
disturbed in transit or storage.
!IMPORTANT NOTE !
Always reseal the pressure test point and check that it is gas tight.
(This accounts for a lot of recalls.)
