Installation instructions Square 40 Gas

Your gas hearth must only be installed by a certified installer and only in combination with the WANDERS
concentric pipe system. Only then will the hearth be approved according to the European CE standards for
gas appliances. We will not give any guarantees if the gas hearth is fitted and/or installed in an incomplete or
improper manner. The pipe system consists of an inner pipe with a diameter of 100 millimetres and an outer
pipe with a diameter of 150 millimetres.
The appliance may only be installed and fitted by a certified installer in accordance with current universal
gas piping regulations and according to the installation instructions mentioned below. Furthermore, the
national and local rules and regulations on placing and using closed gas appliances shall be applicable. Only
certified installers are authorized to change the pre-set values (in line with the regulations) or make any other
adjustments.
Before installing the appliance, the installer must check whether the information on the type tag of
!
the fireplace corresponds with the gas type and gas pressure to which the appliance is connected. If it
does not match, it is not allowed to connect the gas unit.

Placing

The gas hearth is designed to be build in excisting construction and newly build constructions. All materials
used in the area of the hearth need to be heat and fire resistant. The gas hearth must be placed on a floor that
is solid enough to hold it.
The gas hearth can be placed in a crack-free and/or mechanically ventilated home without difficulty. There
is no need for extra ventilation for combustion, or for a smoke and fire vent. Waste gases are discharged by
natural draught via the inner pipe into the open. The oxygen needed for burning the fire is supplied from the
space between the pipes. This is the reason that no insulation must be placed between the inner and the outer
pipe.

Insulation

Due to the high temperatures of the exterior walls (up to approximately 150 °C or 300 °F) it is prohibited to
have any combustible materials close to the channel system. The entire concentric pipe system should be
encased (heat resistant) from the place where it is out of sight up to the outlet in the exterior wall. Ventilate the
encased concentric pipe system by placing a grid near the floor and the ceiling on every floor. Use universal
wall clips with a diameter of 150 mm for anchoring the concentric pipe system.
If an existing chimney is used, first make sure whether the chimney is sufficiently insulated and with sufficient
diameter to accommodate the concentric pipe system. If the chimney was previously used as a wood-burning
or coal-fired stove, the chimney must first be professionally cleaned. You must use special WANDERS connecting
sets for connecting a gas hearth to an existing chimney.
