6 Fire safe installation
To install a gas fireplace as safely as possible, several installation
preparations need to be made. This overview can be used to
assure the fire safety of a conversion of a fireplace.
Fire safety device set-up
Install the device such that there are no flammable materials
around the device or chimney. The device must never be placed
against a back wall of flammable materials.
Flammable materials, such as wood, can combust at a
temperature of 85°C. At high temperatures this can happen
within several minutes (over 200°C) or at lower temperatures
(more than 85°C) this may occur over a period of weeks.
A gas fireplace can achieve temperatures of over 200°C.
Therefore one should use only non-flammable materials around
the fireplace and in the cove.
It is important to follow the installation regulations below
carefully. When the regulations are insufficiently- or not provided
with the aspects of fire safety, the instructions according to NPR
3378-20:2010 are leading.
Protection of wall and ceiling
There are two kinds of walls/ceilings that can be distinguished,
respectively;
1. Walls/ceilings that are made of – or contain flammable
building materials, and all walls on which flammable objects
(e.g. built-in furniture or wooden panels) are mounted on
the side of the wall that is turned away from the fireplace.
2. Walls/ceilings made of mineral building materials (gas
concrete, bricks, lime sandstone etcetera.) of more than
10cm thickness.
Assembly regulations
(Figure 6-1 and 6-2)
• Cover the walls/ceilings with a non-flammable, fire resistant
plate, according to EN 13501-1:A2
• Place a non-flammable, fire resistant plate in front of the
first one at a distance of 2cm.
• Make sure that the two plates are not attached to each other
by screws or nails. Due to their conductivity these metals
can cause problems.
