General instructions
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 preset
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 must not be built into the wall. The
distance from the hearth to the rear wall must be at least
10 cm. 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 00 °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 accommodated 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.
Gas connection
• Use a feed pipe with an approved G/8" stop cock
with coupling.
• De-aerate the supply pipe before fitting and fastening
the appliance.
• Avoid all tension on the operating valve and pipes to
avoid gas leakage.
• Check if the connection is gastight.
