INSTALLATION REQUIREMENTS

DEFINITION

Installation of a Firefox OGF-ME series open fronted steel firebox into a non-combustible enclosure
constructed partially of masonry e.g. brick, concrete or Hebel blocks in conjunction with the specified
steel flueing system to draw and exhaust combustion gases up and away from the gas log firegrate.

1. Ensure that any air extraction devices located in the vicinity of the fireplace will not cause a
negative air pressure (suction) which could cause a spillage of combustion gases into the room where
the firebox is located when in operation.

2. GAS SUPPLY REQUIREMENT: Provide a 12mm (1/2”) copper gas pipe into the chamber with a
tail approx. ¾ of the way into the firebox. An access hole is provided on the right hand side of the unit
130mm up from the base and 140mm in from the front of the unit. For MJ/HR rating of the gas
firegrate burner refer to specification pages.

3. ELECTRICAL SUPPLY: The firebox is supplied with 1.5m of lead and a 3 pin plug located on the
lower left hand side of the unit. The lead must not rise above 100mm of the base level of the firebox.
If connecting to a wall mounted isolating switch, ensure that the switch is far enough away so as to not
obstruct the fitting of a decorative surround i.e. mantelpiece.

4. Construct a non-combustible enclosure as required to suit the selected Firefox OGF-ME series gas
firebox. The enclosure must completely surround the base, sides and back of the unit and rise
300mm above the top of the unit. Plasterboard can be Zero Clearance to the perimeter face flange of
the unit.

5. FLUEING REQUIREMENTS:
. Use the specified single skin galvanised inner active flue ONLY if the firebox and flue is to be

completely enclosed in masonry.

. Use the specified twin skin flue system i.e. galvanised inner active flue PLUS the galvanised

outer casing if the flue is to be exposed close to combustible materials i.e. timber framing.
. Secure inner active flues at each crimp joint with 4 pop rivets.
. Secure outer casings at each crimp joint with 4 x 25mm self tapping screws.
. A 25mm clearance to all combustible materials is required from the outer flue casing.
. Fit approved cowl as specified for the selected firebox/flue.

6. Permanent ventilation equal to the cross sectional area of the specified firebox flue must be
provided into the room/area the gas fire is located.

7. Use only the appropriate Firefox gas firegrate/burner (GFG) in conjunction with the selected Firefox
OGF/ME firebox See GFG Series (GAS FIREGRATE) specifications, located in the following pages.

For installation and commissioning procedure of the gas burner/firegrate (GFG) refer to separate
details entitled: FIREFOX INSTALLATION & OPERATING INSTRUCTIONS ‘GFG’ Series GAS
FIREGRATES.

USER INSTRUCTIONS

Congratulations on having a FIREFOX
fan forced gas log fire installed in your
home. We are sure it will provide you with many
years of realistic fireside pleasure, comfort and
enjoyment.

It is important that you familiarize
yourself with the appliance by reading through
these instructions.

If your installer has not shown you how
to light the FIREFOX gas firegrate which has
been fitted into the unit, refer to the separate
booklet entitled INSTALLATION & OPERATING
INSTRUCTIONS - GFG SERIES (Gas Firegrates

-L/C effect) under Lighting Burner &
Commissioning and also familiarize yourself with
the USER INSTRUCTIONS contained there-in.

Your FIREFOX gas firebox incorporates
a sophisticated heat exchanger design which
collects heat and a 2 speed fan which transfers
the collected heat into the room/area where the
FIREFOX is located. The fan control switch is
located on the lower left hand front of the unit.
The fan can remain OFF whilist the gas firegate
is in operation. To boost heat output simply
select one of the two fan speeds avaliable i.e.
LOW or HIGH.

Your FIREFOX gas unit is relatively
maintenance free. However we recommend that
you have the appliance/installation checked once
a year to ensure correct operation.

SAFETY PRECAUTIONS

As with any live naked flame burning
apparatus, it is important in order to protect
against personal injury or property damage to
treat its operation with care and respect. A
safety screen/fireguard should be used for the
protection of children, elderly and infirm.
