4 Safety
4.1 Safety instructions for installation
Warning:
• Installation must be done by a qualified installer.
• Install the appliance in accordance with the following installation
instructions and the national and local applicable regulations.
•Make sure that the area around the fireplace is free of flammable material
at all times. The minimum safe distance is 180 cm.
• Do not install the appliance against flammable materials. Refer to chapter
5 for minimum clearances and suitable insulation material.
Caution:
• Install the appliance on a floor with adequate load-bearing capacity. Refer
to chapter
9 for the weight of the appliance.
• It is not allowed to connect the appliance to a flue that is also connected to
another appliance.
• Make sure that the chimney has no creaks and is in general good order.
• Install a suitable cap on the chimney outlet to avoid birds' nests build in the
chimney.
• Parts in the appliance can be moved during transportation. Make sure
these parts are in the correct position. See the user manual.
• Do not use masking tape on the appliance. Masking tape can damage the
finish of the appliance.
• Make sure that the chimney temperature class is at least T400 sootfire
resistant.
• Do not install the appliance in a room with a ventilation system that makes
pressures below -15 Pa.
4.2 Safety instructions with regard to the environment
• Dispose of the packing materials in an environmentally friendly way.
• Dispose of ceramic heat-resistant glass as household waste. Do not dispose of
ceramic heat-resistant glass in a glass recycling container.

5 Clearances
Warning: Follow the instructions in this chapter. Failure to follow these
instruction can create a fire hazard.
Warning: Do not put the appliance directly against a flammable or non-
flammable wall.
All clearances to flammable and non-flammable materials mentioned in this chapter must
be obeyed.
5.1 Insulating material requirements
• Use insulating plates with a maximum thermal conductivity of 0.10 W/m.K or a thermal
resistance of minimum 10 K.m/W. The table hereunder shows some examples of
suitable insulating plate materials.
Table 1: Examples of insulation plates
Examples of suitable plate material Thermal conductivity
Promat Promatect L insulating board 0.083 W/m.K
Skamol Skamotec 225 0.06 W/m.K
Skamol Super-Isol 0.08 W/m.K
• Only use white unbound ceramic insulation wool. Do not use glass wool or rock wool,
these materials can cause a bad smell, unwanted smoke and is not applicable for high
temperatures.
Table 2: Ceramic insulation wool requirements
Temperature resistance > 700 °C
Density > 80 kg/m3

Put a non-flammable floor plate with a minimum thickness of 12 mm in front of the
appliance above a flammable floor. The depth of the floor plate is dependent on the
vertical distance between the bottom of the appliance and the floor.
The non-flammable floor plate must have a width that extends minimum 150 mm from
each side of the appliance.
A Minimum 15 cm from the sides of the appliance
B Minimum depth of the non-flammable floor plate (see graph for exact depth)
C Minimum 180 cm clearance from the front of the appliance
Figure 10. Height of appliance versus depth of the non-flammable floor plate
1. Measure the distance between the floor and the bottom of the visible part of the
appliance. This is the distance when the appliance is built into a fireplace surround.
2. Read on the vertical axis of the graph the minimum depth of the non-flammable floor
plate.
Example to find the correct minimum depth of a non-flammable floor plate
If the measured distance between the bottom of the visible part of the appliance is 20 cm,
according to the graph the minimum depth of the floor plate is 47 cm.
