Material selection
The temperature in front of the fire (approximately 200-350 mm x 400 mm wide) can reach up to
40 °C above ambient, which is why material selection is important. For example, vinyl planks are
a popular option for flooring, however vinyl is only rated for ambient temperatures. In this example
it would not be recommended that the fire is installed directly on the floor unless there was some
form of floor protection in front of the fire.
Some material selection guidelines, depending on the material rating, are shown below.

The shaded cells denote measurements A, B, C, and D. These figures are dependent on each other and the
type of installation. There is some wiggle room to these dimensions if they follow some specific calculations.
These calculations are based on figures obtained during in-house temperature testing. For more information
refer to the next page, and page 34.
Just because a material is rated to higher than 60 °C does not mean it will not deteriorate when exposed to heat
cycles. Always refer to the material supplier for suitability. The temperatures given are assuming the fire is operating
in a room temperature of no more than 25 °C. Operation in higher ambient temperatures may result in higher surface
temperatures. Non-combustible materials should be made of heat resistant material.
