INSTALLATION INSTRUCTIONS

SITE REQUIREMENTS

1.FLUE AND CHIMNEY REQUIREMENTS

1.1The chimney or flue system must comply with the rules in force, and must be a minimum of 125mm (5”) in diameter. Precast flues must conform to BS1289: 1986. The cross sectional area of the flue must be 16500 mm2 with a minimum dimension of 90mm.

*When fitting the fire to a precast flue, the total minimum depth of fire opening necessary is (D) 215mm. This allows a 25mm space behind the fire for debris, required on this type of flue system. This is achieved either by using = (A) a 115mm deep starter block +

(B)a 25mm plasterboard and sealed space + (C) 75mm Gazco Spacer (part number 8315) with a marble slip or similar, inserted behind the spacer front flange, see diagram 1.

Or the total depth can be achieved by using a deeper starter block, remedial building work to the front of the fireplace opening, and a marble slip or similar, or a combination of this.

NEVER PLASTER DIRECT TO THE FACE OF A PRECAST FLUE. USE ADHESIVE TO FIX THE PLASTERBOARD TO THE FACE OF THE FLUE AND FINALLY SKIM THE PLASTERBOARD.

The fire can also be fitted into a metal flue box with a 5” (125mm) diameter flexible liner. In this installation a 1” (25mm) rebated fire surround must be used. Refer to diagram 2 for dimensions.

1.2The minimum effective height of the flue or chimney must be 3 m (10ft).

1.3The chimney or flue must be free from any obstruction. Any damper plates should be removed or secured in the fully open position, and no restrictor plates should be fitted.

1.4The chimney should be swept immediately prior to the installation of the fire - unless it can be seen to be clean and unobstructed throughout its entire length.

1.5Ensure that there is a smooth taper transition from the fireplace opening into the chimney or flue.

1.6The flue pull should be checked prior to installation of the fire. Apply a smoke pellet to the flue or chimney opening and ensure that the smoke is drawn into the opening. If there is not a definite flow, preheat the chimney for a few minutes and re-test the flow.

IF THERE IS STILL NO DEFINITE FLOW, THE CHIMNEY MAY REQUIRE ATTENTION - SEEK EXPERT ADVICE.

2.FIRE LOCATION

2.1This fire must stand on a non-combustible hearth that is at least 12mm thick and 50mm thick at least at the periphery. If the fire is installed greater than 50mm above the floor, then no hearth is required, although due consideration should be given to how the heat may affect the floor material.

2.2NOTE: It is recommended you construct the back panel of the fireplace from natural materials cut into three or more sections to prevent cracking. Resin-based materials may not be suitable. This appliance is an effective heat producer and attention must be paid to the construction and finish of the fireplace.

2.3It must be fitted into a non-combustible opening.

2.4These fires must be hearth mounted into a fireplace opening conforming to National Standards. The minimum dimensions shall be as shown in diagram 2.
