DESCRIPTION OF BOILER
1.1
INTRODUCTION
“SUPER FOUR”
boilers are gas-fired
thermal appliances for C.H. and D.H.W.
production.
They are defined as “sealed-room”
appliances because the air necessary
for combustion is drawn in from outsi-
de the ambiences in which they are
installed.
They come complete with all safety and
control devices and appurtenances
required by current standards, and
are built in compliance with the
European Directives pr EN 483 - pr EN
625. These appliances can be fired by
natural gas and L.P.G. (G30 - G31).
The instructions given in this manual
are provided for the installer to ensure
proper installation and perfect opera-
tion of the appliance.
