Warnings Related To Operation; Intended Use; Technical Specification; Design - Defro Home INTRA Series Operating Manual


It is absolutely forbidden to use flammable liquid for
equipment firing up.

If the substrate, on which the equipment is located, is
made of inflammable materials, such as parquet or
floor lining then you should place a protective plate un-
der it (the plate should protrude 250-300 mm from the
front of the equipment).

2.2. WARNINGS RELATED TO OPERATION


Equipment should be shutdown in case of failure or in-
correct operation.

Fuel used in the fireplace insert should meet the con-
ditions described in this manual.

Internal parts of the fireplace insert should not be
washed with water.

Do not allow contact with water, and first of all, do not
wash any varnished coatings before they cure. The
coating of new devices is not an anti-corrosion coating,
heat-resistant paint only gains its protective properties
after curing under the influence of heat (after several
firings).

Do not expose the body to the action of hot air for a
long period of time. Do not heat excessively the room
where you are staying and where the equipment is in-
stalled. It may have an adverse impact on physical
condition and be a reason for health problems.

Equipment should be installed in rooms with fire pro-
tection and equipped with all required components
such as supply (with air) and flue gas discharge.

Fireplace insert and cladding made of ceramics should
be stored in rooms free from moisture and they cannot
be exposed to adverse effects of the weather.

It is not recommended to place body of the fireplace
insert directly on the floor and if such floor is made of
inflammable materials it should be properly insulated.

To facilitate possible interventions by the technical
personnel you should not place the fireplace insert in-
side the closed rooms and just by the walls what can
also disturb air intake.

Always make sure and check whether doors of the
combustion chamber are tightly closed when the
equipment is operating.

Equipment consumes exact amount of air which is re-
quired for combustion process; it is recommended to
connect the fireplace insert to air intake from outside
using suitable pipe and through a special outlet lo-
cated at the back of the equipment.
ADDITIONAL INFORMATION

In case of any problems you should contact sales out-
let or qualified personnel authorized by DEFRO. Re-
quest original spare parts if the repair is necessary.

Use only fuel with properties compatible with the rec-
ommendations of this operating manual.

Check and clean flue gas discharge ducts (connecting
piece to flue) periodically.

Store this manual carefully because it should be avail-
able for a whole period of equipment operation. In
case of sale of giving the equipment to the other user
you should always make sure whether the product has
the manual enclosed.

Request a new copy from an authorized sales outlet in
DEFRO company if it has been lost.
