OGF - ZC Series
INSTALLATION REQUIREMENTS
DEFINITION
Installation of a Firefox OGF-ZC series open fronted steel firebox into a timber framed and
plasterboard enclosure 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 timber framing as required to suit the selected Firefox firebox (See example detail).
. Maintain 25mm clearance to the sides and back of the firebox and 50mm clearance from the
top from combustible materials.
. Secure firebox into position with metal strapping.
. Plasterboard can be zero clearance to the perimeter face flange of the unit.
5. FLUEING REQUIREMENTS:
. Use the specified Twin Skin Flue system i.e. stainless steel inner flue PLUS the galvanized steel
outer flue casing.
. Secure inner stainless flues at each crimp joint with 4 pop rivets.
. Secure outer galvanized casing 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/ZC firebox
See GFG (GAS FIREGRATE) Specifications located in the following pages.
