1 INTRODUCTION
1.1 FOREWORD
We would like to congratulate you on your purchase of this modern Barbas built-in wood
fire. This quality product will give you years of heating pleasure as you enjoy the play of
the flames and the cosy glow of the fire.
The appliance is fitted with a ceramic particulate filter that ensures low emission values
for the flue gases and a very low particulate emission.
This manual contains directions for both positioning the appliance and for its
environmentally-friendly use. It also contains technical data for the appliance, parts
information and directions in the event of problems. Study this manual carefully before
using the stove. We recommend you keep this manual in a safe place for reference
purposes.
1.2 SAFETY AND INSTALLATION INSTRUCTIONS
Safety
• Do not place flammable objects within 150 cm of the appliance. Pay special attention
to furnishings and ornaments around the fire.
• When you use your fire, the exterior will become hot. Always wear the glove or use
the accessories supplied when filling etc. Protect yourself and others (especially
children!) from burns. Do not leave children unattended when the fire is burning.
• Watch your clothing. Synthetic clothing in particular can easily catch fire and burn
intensely.
• Do not approach the appliance with flammable materials or liquids. Any work with
solvents, adhesives etc. in the space heated by the fire can be very dangerous.
• Make sure you know what state your chimney is in. Cracks in the chimney may not
only lead to damp, staining of walls and leaking of smoke, they can also impair the
carrying off of smoke. Make sure you get proper advice from your Barbas dealer or
other specialist company.
• Avoid chimney fires!
Have your chimney swept at least once per year - more often if you use your fire a
lot. Prevent excessive deposits of soot inside the chimney by not burning freshly-cut
wood. Instead, burn clean, dry chopped wood.
• Do not use your built-in fire as a barbecue. This can cause (flammable) fat
deposits
to be left in the chimney and hastens the chimney becoming clogged. Prevent your
chimney being soiled from above (birds’ nests etc.) by fitting a suitable cap to the
chimney pot.

12
ENERGA 70-55 TUNNEL
• Follow the instructions issued by your local fire brigade.
The fire can be taken in operation if national and local regulations are satisfied. The
required constructive adaptations should be satisfied as well.
Installation Instructions
• Wood and wood briquettes may be stoked in the fire.
Coals can’t be burned in the fire.
• Never use the appliance to burn rubbish.
• Please read all instructions/stickers on and around the appliance.
• Please also study the directions for use before using the appliance for the first time.
When you first fire up your appliance, there are a number of extra points you should
take into account. See chapter 6.
• In transit, some parts of the appliance may have moved from their original place.
Check that the door opens and closes, the particulate filter and retardant plate (brake
plate) are fitted correctly to the brackets at the top of the fire, the side-panels are
fixed to the walls and the bottom plates have not moved. Check whether the grate is
lying correctly and there are no foreign objects in the ashtray.
• Avoid over-loading (white burning glow), caused, for example, by lengthy burning
with a fully open primary air vent (combustion air supply slider all the way to “ +”),
or by burning too much wood in one go. The fire can then become over-heated.
The grate, particulate filter and the metal flue gas flap could then be damaged.
• The appliance may only be set up if the appliance and location meets the
- national and local installation regulations;
- local fire brigade regulations and required architectural provisions.

2.3 ACCESSORIES
The following accessories can be supplied by your dealer:
2.4 BASIC REQUIREMENTS FOR POSITIONING BUILT-IN FIRES
General
The appliance may only be set up in a room in which the location, architectural con-
struction and activity is not endangered by the presence of a fire. The surface on which
the appliance is to be placed must be correctly shaped and big enough to accommodate
the appliance safely (in compliance with DIN 18895, part 1).
When fitting, all local and/or national safety regulations must be followed closely, parti-
cularly in rooms with walls/floors containing flammable material. If in doubt, consult the
fire prevention department of your local fire brigade and/or the architectural department
of your local authority.
Built-in fires may solely be used in:
• Rooms with at least one outer door or window that can be opened;
• A suite of rooms connected directly or indirectly with each other with a collective
supply of air.
In the aforementioned cases, the capacity of the room(s) must be at least 4 m³ per kW
of nominal output.
Built-in fires may only be constructed or moved into rooms where at least 360 m3
combustion air per hour and per m2clear fire opening can circulate. If there are any
other fire-burning appliances in the same room, at least 540 m³ combustion air per hour
and per m² clear fire opening must be in circulation.
Other appliances must have at least 1.6 m³ combustion air per hour, per total nominal
output in kW at a calculated pressure difference of 0.04 mbar with the ambient air.

19
ENERGA 70-55 TUNNEL
Built-in fires must not be used in:
• Staircases, except in buildings with no more than two apartments.
• Entrances providing general access.
• Rooms in which highly inflammable or explosive substances are processed or
manufactured.
• Garages;
• Rooms or apartments with air conditioning or convection heating provided by fans,
unless it can be guaranteed that they will not interfere with the working of the fire.
This is under the following conditions:
°the installation merely circulates air around the room;
°the installation has sufficient safety provisions preventing the possibility of
spontaneous and automatic underpressure being created in the room in which the
fire is situated;
°that the combustion air stream created by the fire and the volume streams of the
extraction installations in the room and adjoining rooms connected by de-aeration
connections do not create underpressure greater than 0.04 mbar. This must also
be guaranteed if easily accessible air-conditioning equipment is moved or removed
from the room.
Provision of combustion and convection air
The local chimney sweep/authorities must be consulted prior to fitting regarding the
suitability and combustion air supply. DIN 18160 must be observed. DIN 18895 parts 1
and 3 also apply.
The air, which is piped in through a grill in the wall, ensures that the air in the room is
refreshed and is also used for the combustion process.
The combustion air is sucked in through the grill in the chimney breast and through the
opening underneath, or at the side of the appliance. Because some of this air passes
through the chimney breast, it can be referred to as pre-heated combustion air.
The built-in appliance can also be fitted with an air duct which draws the combustion air
directly from outside.
The air intake must have a opening of at least Ø125 mm. If required, the air pipe can be
fitted with a control damper. In this case, the position of the damper must be visible from
the outside. The use of a direct combustion air intake is strongly advised if the appliance
is fitted with a convection set.

ENERGA 70-55 TUNNEL
The casing / fireplace
• The casing may not be directly connected to the built-in fire, but must be constructed
so that it is self-supporting; a mantle iron or lintel should be used for this. The
covering in the area must be of non-flammable materials of flame-retardant material
class A1. This includes bricks, cladding, ceramic tiles, metal or plasterwork, Promatec
and Nobranda.
• The opening for incoming and outgoing air from the casing must be at least totally
900 cm². At least 200 cm² from the opening for incoming and outgoing air must not be
closable.
• The ventilation of the casing/fireplace can be provided by grills, but this can also be
achieved by not building the fireplace right up to the ceiling (leaving a gap of 5 cm).
