3.1 Site Requirements
1. The Baxi Wentworth Classic and Kingston 2 Classic
gas fires can be fitted to an installation with the following
flue systems:
•
Fabricated steel
•
Conventional brick or stone
3.2 Ventilation
1. No purpose provided ventilation is normally required for
the appliance, normal adventitious room ventilation being
sufficient. Reference should be made to BS 5871 Part 2.
For Ireland refer to IS 813 Section 10 of the Irish
Ventilation Requirements.
3.3 Masonry Flues
1. Any chairbrick must be removed if necessary to achieve
the minimum depth. The fireplace opening must be a
minimum of 408mm (16
1
/
16
in) wide (Fig. 2).
2. A conventional brick or stone chimney must have
minimum effective cross-sectional dimension of 225mm x
225mm (9 in x 9 in) or be a lined flue of minimum diameter
125mm (5 in). The liner should be terminated at the top of
the builders opening and sealed from the chimney. The
minimum depth is shown in Fig. 3. If necessary remove
either the knee or the whole chalrbrick.
3. The fireplace must have a flat vertical surface
measuring 605mm (23
13
/
16
in) high by 517mm (20
1
/
8
in)
wide (Wentworth) or 660mm (26 in) high by 563mm (22
5
/
32
in) wide (Kingston 2), centrally placed about the opening.
This allows an effective seal to be made between the wall
and fire.
Also this area must be of non-combustible
material.
If a fire surround Is to be fitted its rear section
must meet the same requirements. Any gaps between the
wall and surround must be sealed (Fig. 4).
