Description of FR-850 Design
This appliance is supplied as a complete suite of gas fire burner unit, enclosure
and fascia. To comply with the approval this fire must be installed as designed.
There are two versions which can be purchased by the customer depending on
site specific conditions like chimney size and room ventilation. Check the data
plate to confirm which version is to be installed. The versions are:
•
FR850-V - This version has a minimum flue requirement of 178mm
diameter or Class 1 chimney at 2m in length. This version needs room
ventilation with a 100cm2 air vent to the outside air.
•
FR850-NV – This version has a minimum flue size of 127mm diameter flue
or Class 2 chimney at 3m in length. This version does not need room
ventilation. The enclosure on this version features a glass panel to reduce
the opening. This glass panel must be fitted at the factory at time of order.

Gas Supply
: Do not install the fire until the gas pipework has been checked
and a flow rate performed to ensure that the minimum flow rate specified in
the technical section can be maintained when the fire operates on full.
Failure to do this may result in the fire failing the commissioning test or
becoming unreliable. This then may require removal of the fire and pipework
to rectify the gas pressure.
Gas Flow Rate: NG = 0.705 m3/Hour
Gas Flow Rate: LPG = 0.278 m3/Hour
•
Room Ventilation:
The FR850-V version of this fire requires a 100cm2 free
air wall vent in the room in which it is installed.
•
Fascia Trim:
There is an optional trim which can be fitted to the fire. Only a
trim supplied by Spirit Fires is to be used. Using a non-standard trim will
invalidate the warranty.
•
Gather:
An optional gather is available to attach the enclosure to a flue
liner. Depending on the model purchased the gather will have either a
130mm or 180mm spigot (see technical section). If installing the fire in a
brick built chimney we advise buying the gather as this will stop debris
falling into the fire and improve efficiency.
•
Flue System:
o
FR-850-V
– Class 1 or 180mm flue of minimum 2 metres.
o
FR-850-NV
– Class 2 or 130mm flue of minimum 3 metres (this
model can also be used with the same flue as the FR-850-V)
•
Flame:
It is normal with this type of appliance for the flame to be directed
towards the back of the enclosure. This will be worse where the fire is
installed without the official gather and with a longer flue.
•
Remote Heat Shield:
This fire is approved
with the heat shield in place.
The fire should never be operated without the heat shield; any resulting
damage caused by heat is not covered by the warranty.
