INSTALLATION INSTRUCTIONS
chimney then a draught stabiliser should be fitted. If in doubt about
the chimney seek expert advice.
HEARTH AND FIRE SURROUND
The stove must be installed above a fireproof hearth of minimum
250mm depth in accordance with local building regulations, but
ideally 580mm deep to match the projection of the open door. The
positioning of the stove and the size of the hearth
building regulations for solid fuel appliances. If in doubt as to the
positioning of the stove expert advice should be sought either from
the supplier or the local building inspector.
If a wooden mantelpiece or beam is used in the fireplace it should be
a minimum of dimension 'D' from the appliance. In some situations it
may be necessary to shield the beam or mantelpiece to protect it.
In order for the appliance to fit into the fire surround there must be a
flat area around the opening. Details are shown in Fig. 10 & 12.
PREPARATION OF FIREPLACE
If the fireplace contains combustible materials, two air vents of 80mm

(Bay 5 & VL) or 100mm (Bay 5GT) diameter must be fitted through
the insulation and the wall of the fireplace to provide a continual air
flow around the stove. Similar vents must be placed between the
closure plate and the top of the stove to ventilate the cavity. It is
recommended that Calcium Silicate board is used (80mm board for
Bay 5 & VL, 100mm board for Bay 5GT), with a 100mm air gap
between the stove and the insulation (see Fig. 11).

If the fireplace does not contain combustible materials, it is still
recommended to have a layer of insulation or ventilate the space
between the casing and the outer wall. The insulation may consist of a
layer of mineral fibre or a vermiculite concrete mix (see Step 4). If
rockwool is being used, insert this into the opening before sliding in
the convection casing.
Before fitting the appliance into an existing fireplace remove the
fireback and any loose in-fill material.
The surround and opening for the appliance must conform with
Fig.12. The flat area around the opening should be a minimum of
700mm wide and 600mm high. Ensure that the hearth and the base
in the opening are flat, level, and at right angles to the surround.
For the Bay 5GT, consider where the low voltage power supply for
the fans is to be situated, and install electrical conduit from that point
to back left of the convection casing.
CONNECTING THE FANS (BAY 5GT ONLY)
The adaptor provided must be connected to a suitable mains socket.
