2.1 Technical characteristics
The ALTAIR RTN is a boiler with a
high performance heat exchanger
that works with gas burners at atmo-
spheric pressure. The following
models are available:
ALTAIR RTN E 18 and RTN 18 with
a heat output of 18 kW.
ALTAIR RTN E 24 and RTN 24 with
a heat output of 24 kW.
ALTAIR RTN E 32 and RTN 32 with
a heat output of 31,5 kW.
ALTAIR RTN E 36 and RTN 36 with
a heat output of 36 kW.
ALTAIR RTN E 48 and RTN 48 with
a heat output of 48 kW.
ALTAIR RTN E 60 with a heat output
of 60 kW.
ALTAIR RTN E 70 with a heat output
of 70 kW.
ALTAIR RTN E 80 with a heat output
of 80 kW.
ALTAIR RTN E 90 with a heat output
of 90 kW.
ALTAIR RTN E 100 heat output of
100 kW.
RTN 18 to RTN 36 and RTN E 18 to
RTN E 36 models of ALTAIR boilers
can be supplied in a PV version,
which means that they have a circu-
lation pump and an 8 lit. expansion
tank.
ALTAIR RTN E boilers are equipped
with an electronic card for checking
the flame and have an electronic
ignition (which is indicated by the
addition of the letter E in the model
name).
The models from RTN 18 to RTN 48
are fitted with a thermoelectric valve
and a piezoelectric ignition unit.
ALTAIR boilers meet the essential
requirements laid down in EEC
Directives for this product and Gas

Directive 73/23/EEC dated 19th
February 1973, as amended by
Directive 93/68/EEC dated 22nd July
1993,
and they are fitted with all the safety
devices called for in the current stan-
dards for this type of product.
The main technical characteristics of
