WANDERS Domus Mode D'emploi Et Instructions D'installation page 21

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
• The Domus or Luna Petite gas hearth can only be fired
by natural gas.
• The gas governor is located underneath the appliance
behind the operation flap.
• 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.
Placing of the concentric channel
system
The concentric channel system consists of three parts:
the channels itself, the transit through the roof or through
a wall and the outflow.
Instructions for placing the outflow
The outflow of the pipe system can be placed on top of
the roof or against the side wall of the house.
Outflow on top of the roof
When placing the outflow on top of the roof, make sure
that there is a distance of at least 50 cm between the
outflow and the edges of the roof, with the exception of
a possible existing ridge. You must also take the place
of the outflow into account in relation to the existing
ventilation openings, movable windows and combustion
air supply provisions. Please consult the national and
local requirements.
Outflow into the wall
When placing the outflow into the side wall, make sure
that there is distance of at least 50 cm between the
outflow and the corners of the building, eaves, gutters,
balconies and etceteras. You need not have this distance
when the outflow runs through to at least the front of the
overhanging part.
You must also take the place of the outflow into account
in relation to the existing ventilation openings, movable
windows and combustion air supply provisions. Please
consult the national and local requirements.
Placing possibilities of the pipe system
The total length of the pipe system must never be more
than 0 metres excluding the passage through the wall
and the outflow. A 90° square angle counts as a length of
 metres. A 45° turn counts as a length of  metre.
For the combined flue tube and combustion air supply
you must apply one of the following placing possibilities
of the WANDERS concentric pipe systems: with wall
duct, with roof duct or with roof duct with bend.
