the fireplace to be fired with another kind of gas.
Wanders cannot be held responsible for any cracks in stuccoed walls or discolouration of walls, ceilings and/or
grates after burning the fireplace. Discolouration is caused by the burning of dust particles in the convection
cover. To reduce the chance of cracks in stucco and to minimize discolouration we refer to the advice given for
decorative hearths. Your installer can give you more information.
Any complaints will be dealt with after the sales firm, the installer or the gas company filed a complaint and
sent a copy of the purchase receipt with purchase date. Any repairs do not entitle you to extend the guarantee
term. All consequential damages or loss are excluded.

Installation instructions Stealth 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 appliance is designed to be mounted on a wall which should be strong enough to hold the weight of the
appliance. All materials used in the area of the hearth need to be heat and fire resistant.
The appliance 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.
