Installation instructions for Cocos and Cocos tunnel

Your gas hearth must only be installed by a certified installer in combination with WANDERS' concentric pipe
system. Only then will the hearth be approved according to the European CE standard for gas appliances. We
will not give any guarantees if the gas stove 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 fumes will be extracted from the stove through natural draft using the 100 mm innerpipe,
while the outer 150 mm pipe supplies the fresh combustionair.
The appliance may only be installed and connected by a certified installer in accordance with the standard
gas installation instructions and the installation requirements mentioned below. Furthermore, the national
and local rules and regulations on placing and using closed gas appliances shall be applicable. Only a certified
installer has the authority to change the setting values (in accordance with the requirements) and to carry out
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, you are not allowed to connect the gas hearth.

Placing

The gas hearth was designed to be built into a newly-built fireplace made of incombustible material. If there
are any flammable materials behind or along the gas stove, you will have to place fireproof sheets.
The gas fireplace 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 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 or to place any combustible materials close to the channel system. The entire concentric pipe system
should be encased with fireproof material 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 grate 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 is wide
!
enough to accommodate the concentric pipe system. If the chimney was previously used as a wood-
burning or coal-fired stove, it must first be professionally cleaned. You must use special WANDERS
connecting sets for connecting a gas hearth to an existing chimney.

Gas connection

A cover frame for mounting the receiver and gasblock is delivered with the appliance.
Place the cover frame to the right or left of the appliance.
Use a feed pipe with an approved G3/8" stop cock with coupling.
De-aerate the supply pipe before fitting and fastening the appliance.
Avoid tension on the operating valve and pipes to avoid gas leakage.
Check if the connection is gastight.
Make sure the pilot and the burner pipes are not damaged during installation
