Storing; Operating Conditions - Munters GFn Mode D'emploi Et D'entretien

The air heater is delivered complete, factory
assembled apart from external components listed
below. These components can be included in the
delivery, but the assembly or connection has to be
done at the installation site:
• exhaust pipe system (available only on request);
• room or remote thermostat (available only on
request);
• farm controller (available only on request).
The control panel components and features are as
in .
WARNING Use only the approved burner
components supplied by the manufacturer of the air
heater. If the burner is replaced by one that is not
approved by the manufacturer of the air heater,
even if it has similar feature then, this is considered
improper use of the machine and could cancel the
CE marking.
GFn is designed to deliver heating output: 80 kW
(detailed info see Appendix). The stated heating
output data must be interpreted as approximate and
not absolute reference, because it is subject to
possible variations due to tolerances of the
elements taken as reference and, in some cases,
modification of the
manufacturers notice.
environmental conditions are important as well, so
the altitude, atmospheric pressure, relative humidity
and environmental temperature might also affect
these values.
NOTE The exhaust piping system is not delivered
as standard, it is available on request.

3.4 Storing

When the air heater is not going to be installed
immediately after delivery or it has to be stored for a
long period of time then, it is important to follow
these rules and guidelines:
• store the air heater properly even when it is not
used;
• the permissible ambient temperature range for
storing is 0°C to +70°C, with maximum relative
humidity of 80%;
• place the air heater on stable horizontal and flat
surface;
• make sure the air heater are protected from
possible damage;
• store the air heater in a dry place under cover,
protected from elements of nature including dust,
frost, rain, snow and aggressive contaminants;
• in case of long term storage it is recommended to
manually rotate the fan regularly to prevent
failure;
• stack the air heater as indicated on the
packaging. At maximum 3 packaged heaters can
be stacked.

WARNING
in areas where the entrance and access of people
younger than 14 years old is forbidden. Do not
install or operate the air heater in areas where

Altitude above sea level
NOTE When using the standard air heater at
elevations close to 1000 m, air supply adjustment
periodic monitoring and additional maintenance by
qualified technicians are necessary to assure proper
functioning and correct exhaust emissions.
Low ambient temperature cause fuels to gel or
condensate. If gelled or compensated fuels reach
the burner then, the ignition fails and/or internal
components (e.g. fuel pump, gas train) are
damaged. The user must ensure proper fuel state
for all conditions all times.
For mechanical ventilation e.g. exhaust fans, the
minimum ventilation requirement is 800 m
