Wet Stove Installation Guide
In most buildings with solid concrete or stone floors, the requirement will
be met by the floor itself, but mark the hearth to ensure floor coverings
are kept well away or use different levels to mark the hearth perimeter.
Please be aware that hot air can cause staining above the fire in a similar
fashion to walls above radiators. To help prevent this and cracking we
recommend that any plaster above the fire should be fitted with reinforcing
expanding mesh for at least 220mm above, and the full width of the fire.
You should also use a suitably heat resistant plaster which should be
allowed sufficient time to fully dry before using the stove or cracking is
likely to occur.

Combustible Materials
Please view the product sheet which accompanied your stove for specific
minimum distances to combustible measurements.
Ideally, adjacent walls should be of suitable non-combustible
construction, preferably brickwork.
In large fireplaces take care that any supporting beam is protected by
a 13mm sheet of heat resistant fire board spaced 12mm off the surface
with strips of non-combustible material. Make sure that there is a gap
between an un-insulated flue system and any combustible material. This
gap must be at least 3X the outside diameter of the flue pipe, or 1.5X
the flue diameter to non combustible surfaces. Please consult the flue
manufacturers specification for insulated flues.
3.3
Air for Combustion
All stoves require ventilation to burn safely and correctly. There are a
number of requirements that need to be met when installing a stove, for
example, allowing for the permeability of the house (air permeability is the
general seepage of air into the house via air vents, doors and windows
etc.)
There must always be a permanent means of providing air for
combustion into the room in which the stove is installed. Air starvation
will result in poor flue draw and may cause smoke to leak into the room.
