Environmental Conditions And Operating Limits; Regulations For Operation With Fireplaces; Technical Data - Maico ER GH Mounting Instructions

7. Environmental conditions and
operating limits
Permitted maximum air temperature + 40 °C.
The domestic air supply must be set up so
that virtually no air can flow into the living
areas from the kitchen, bathroom or WC.
A room from which the air has to be extracted
must be fitted with a non-closable, free supply
air cross section of at least 150 cm², e. g. with
Maico door ventilation grille MLK.
ER EC units have resistance to interference
in line with EN 55014-2 (depending on pulse
shape and an energy factor of 1000 to 4000 V).
These values can be exceeded when
operating with fluorescent tubes. In this case,
additional interference suppression measures
(L, C components or RC module, protection
diodes, varistors) are required.
7.1 Regulations for operation with
fireplaces
For operation with air-ventilated fireplaces,
sufficient supply air intake must be
ensured. The maximum permitted pressure
difference per residential unit is 4 Pa.
The fan may only be installed in residential
units with air-ventilated fireplaces if:
● the evaluation criteria drawn up by the
responsible, regional master chimney
sweep are met,
● a parallel operation of air-ventilated
fireplaces for liquid or gaseous fuels and
the air-extracting equipment can be
prevented, or
● the extraction of exhaust gas from the air-
ventilated fireplaces is monitored by
special safety equipment. The ventilation
system or the fireplaces must be switched
off if the equipment is triggered.
