FLOORING AND HEARTH MATERIAL SELECTION
The temperature in front of the fire (200-350 mm x 400 mm wide) can reach up to 40 °C above ambient, therefore
material selection is important. Some guidelines are detailed below. For example, vinyl planks are often only rated
for ambient temperatures. Consequently, the heater would not be suitable for installation directly on that flooring
type.

The shaded cells above denote measurements A, B, C, and D. These figures are dependent on each other and the type
of installation. These dimensions may be refined with some specific calculations. These calculations are based on figures
obtained during in-house temperature testing. For more information refer to the next page.
Even if a material is rated above 60 °C it may still be subject to deterioration when exposed to heat cycles. Always
refer to the materials supplier for suitability. The temperatures given assume the heater is operating in a room
temperature of 25 °C or less. Operation in higher ambient temperatures may result in higher surface temperatures.
WARNING
RINNAI DOES NOT TAKE ANY RESPONSIBILITY FOR ANY DAMAGE OCCURRING
TO ANY ITEMS INSTALLED IN THE VICINITY OF THE HEATER.
