INTRODUCTION
“PLANET DEWY 30 BFR”
boilers are pre-
mix condensation thermal appliances inten-
ded for heating only, integrated in modular
units of three or four boilers independent of
one another installed in a sequence or in
cascade. They comply with the european
directives 90/396/CEE, 89/336/CEE,
73/23/CEE, 92/42/CEE and with the
european specification EN 483.
In the case of installation in modular units,
two kit are supplied for hydraulic and elec-
trical connection and release of flue gases
for three boilers in sequences, including
assembly instructions:
– kit code 8101300 for connection of
three boilers in sequence.
– kit code 8101400 for connection of four
boilers in sequence.
The instructions given in this manual are
provided to ensure proper installation and
perfect operation of the appliance.
