Lotus H470W, Assembly And User Instructions Manual

Page: 6 / 19

The Base
The base must, of course, be firm and have adequate load-bearing capacity.
This will usually pose no problem when assembling in an open fireplace.
In case of an inflammable floor, the height of the foundation for the insert must
be minimum 300mm.
Distance to inflammable material
When the fireplace insert is mounted in an existing brick fireplace, the
requirements for distance to inflammable material and fireproofing on the floor
will usually be in order.
If it is a matter of a new building, reference is made to any local regulations on
fireproofing etc. You may contact your chimney sweeper for clarification of
any issues of doubt.
For furniture, a distance of 0, 8 metres is recommended.
Distance to non-inflammable material
For non-inflammable material, no requirements apply.
The Chimney
A good chimney draught is essential for how well a fireplace insert will burn.
Note that there should be access to cleaning doors.
The working height of the chimney should typically range between 3.5 and 4.5
metres. Working height shall be understood as the distance from the fireplace
insert top to the top of the chimney.
The internal diameter of the chimney shall be min. 150 mm (inside dim.) in
steel chimneys and min.175-180 mm in brick chimneys or chimneys made of
ceramic units as their inside surface will frequently be rough and will offer
resistance.
All joints and connecting points shall, of course, be tight, and the chimney shall
provide a draught of min. 1.2 mm water head (12 Pa).
