7b. - Maximum and Minimum Flue Sizes
8. - FLUE REQUIREMENTS
a.
The Fire is supplied with a specially designed flue system and no other flue system can be used.
b.
The Fire and Flue Terminal System must be sited in accordance with BS5440 : Part 1. See Diagram and table on Page 4, which
shows Acceptable Flue Terminal Positions.
c.
The Terminal Guard supplied with the fire
MUST
be used if there is free access to the area of the Flue Terminal.
d.
The Flue Terminal will become VERY HOT when the fire is in operation.
e.
The Standard Flue caters for Wall up to a maximum of 500mm thick and a minimum of 100mm thick.
f.
In the majority of Installations Building Work will be required, be it Masonry or Stud Work. For traditional buildings sections 11 & 12
shows the various options, one which
must
be decided before proceeding. However, in the case of Timber Frame Houses please
refer to section 13.
9. - VENTILATION
a.
No additional purpose provided ventilation is required for this fire.
b.
This Appliance is fitted with a Flame Failure Safety Pilot System, which automatically shuts off the gas supply if the flame goes out for
any reason. It
MUST NOT
be tampered with and only replaced with a genuine Nu-Flame Pilot Assembly.
10. - GAS SUPPLY
It Is Recommended to Check The Next Section as Building Work May Affect the Gas Supply Routing.
With Timber Frame Houses Consult your Designer or Architect and refer to Section 13.
a.
Carry out a gas soundness test before working on the gas supply.
b.
Gas supply provision should be made in accordance with the latest Gas Safety (Installation and Use) Regulations as amended.
c.
Confirm that the fire has been supplied for the correct gas to be used by checking the Data Badge in the base of the fire.
d.
A route for a concealed gas supply is provided through a hole in the rear of the fire, at a position of 65mm to the left of the centre
of the fire and 39mm up from the base of the Fireplace/Builders opening. An isolation elbow is provided at the control inlet.
Your 8mm gas supply pipe needs to protrude through the back of the convector box by approximately 145mm to achieve a neat
connection onto the back of the isolator elbow on the burner.
(This applies to both Manually Controlled and Thermatronic Controlled burners.)
IMPORTANT : ENSURE THE GAS SUPPLY PIPE IS ROUTED UNDER THE PIPEWORK OF THE BURNER ASSEMBLY
SPECIFICALLY WITH THE THERMATRONIC CONTROL AS THE BURNER ASSEMBLY AS TO BE REMOVED DURING
INSTALLATION AND FOR SERVICING.
e.
Where the gas supply passes through walls, floors, voids, concrete and wall cavities the supply should be sleeved.
f.
Determine the gas supply pipe size required taking into account any other gas appliances.
g.
Determine where the gas supply pipe needs to terminate and fit the 8mm compression isolation/pressure test elbow provided.
h.
In common with all other gas appliances, dirt and debris in the gas system can block the valve and gas injectors on this appliance, and
faults caused by this are not covered by the guarantee.
Therefore it is important that all gas pipes
MUST
be purged of both air and debris.
i
If you suspect that there may still be dirt and/or debris in the gas system, fit a filter in the pipeline, before the gas isolation/pressure
test elbow.
j.
Do
not
use jointing compound on any compression fittings on the fire. The use of jointing compound on the compression joints on this
appliance will possibly invalidate the guarantee, as it can get into the control mechanism and cause a malfunction.
k.
Seal off the isolation/pressure test elbow and check all gas connections for gas soundness before proceeding to fit the fire.
! IMPORTANT NOTE !
Always reseal the pressure test point & check that it is gas tight - this accounts for a lot of recalls.
