INSTALLATION REQUIREMENTS
DEFINITION
Installation of a Firefox OGF-RT series open fronted steel firebox into an existing fireplace chamber and
chimney which must be completely constructed of masonry and otherwise suitable for solid fuel burning
e.g. wood.
1. Check that the fireplace chamber and chimney is structurally sound.
2. Chimney dampers or baffles must be removed or permanently fixed open. The chimney must be free of
any obstructions which may cause a restriction in up-draught. It is mandatory that the fireplace has
sufficient up-draught in order to draw and exhaust combustion gases away and up the chimney.
3. Check that any air extraction devices located in the vicinity of the fireplace do not cause a
negative air pressure (suction) which could cause a spillage of combustion gases into the room where the
fireplace is located when in operation.
4. Permanent ventilation with a minimum cross sectional area of 40,000mm sq (64” sq) must be provided
into the room/area where the gas fire is located.
5. The fireplace chamber must be wide and deep enough to fully accommodate the Firefox steel firebox.
The masonry rollback at the rear of the existing fireplace chamber may be removed if extra depth is
required. The exhaust outlet at the top of the Firefox gas firebox must be free of obstruction so combustion
waste can exhaust freely up into the chimney and away.
6. 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.
7. 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.
8. Wrap the firebox with the insulation provided and slide the unit into the chamber. The firebox must be
completely sealed around the perimeter face of the existing fireplace opening.
9. Use only the appropriate Firefox gas firegrate/burner (GFG) in conjunction with the selected Firefox
OGF/RT firebox See GFG Series (GAS FIREGRATE) specifications, located in the following pages.
10. A gas cowl with a minimum diameter of 225mm approved AGA must be fitted to the top of the chimney.
For installation and commissioning procedure of the gas burner/firegrate (GFG) refer to separate details
entitled: 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.
