DESCRIPTION
These mach nes are heat ng un ts to be used for a r heat ng. They are essent ally thermal un ts of exchange
between the combust on products of an atmospher c burner and the a r flow generated by a vent lat on un t
not ncluded n the scope of supply. The a r to be heated s sucked by the vent lat on un t and, when t laps
the hot surface of the heat exchanger, t s heated - ncreas ng ts temperature; then t can be d str buted
both d rectly and through proper channels. Trough th s heat ng system, the plant costs can be remarkably
reduced and a rel able operat ng economy can be reached.
WARNING !
The heat ng sect ons type 1-2-3-4-5-6 are des gned to be nstalled ndoors, and protected from atmospher c
agents.
Heat ng un ts type 7-8-9-10-11-12 have been conce ved to be nstalled outdoors.

STOP
Do not stop the machine by disconnecting it from the power supply, since the thermal
energy stored in the heat exchanger could dangerously overheat it, damaging the warm air
heater. Moreover the LIMIT thermostat could be triggered and it might be necessary to
manually unblock it.

LOCATION
The nstallat on place must be chosen by the plant des gner or by a person competent n th s matter; th s
place must meet the requ rements spec f ed by the Standards and Regulat ons n force; generally, spec al
author sat ons are to be obta ned (e.g. town-plann ng, arch tectural, f re-f ght ng, env ronmental regulat ons
etc.)
Therefore, before nstall ng the appl ance, t s adv sable to request and obta n the necessary author sat ons.
We suggest not to install the machine:
•n places w th aggress ve atmosphere;
•n narrow places where the heater no se level can be magn f ed by reverberat on and resonance;
•n corners where leaves can depos t or any other mater als m ght obstruct the a r open ng, thus
decreas ng the heater eff c ency;
• n pressur sed areas;
•n depressur sed areas;
•outdoors, f not prov ded w th a protect on aga nst bad weather cond t ons ( f they are not mach nes
adequately conce ved for such use).

RESPECT AREA
The machine shall be easily and safely reached without needing special equipment (ladders -
movable platforms -etc.). Around the mach ne, m n mum d stances shall be compl ed w th so that the
control and/or ma ntenance operat ons can be performed and that no obstacles block the a r flow.
Any law or spec f c regulat ons (e.g. f re prevent on) shall be compl ed w th. Consult the plant
des gner.

CONDENSATION CHECK
The appl ance s des gned to be operated w th the heat ng capac ty and the a r flow rate spec f ed n the
Data Sheet chapter. If the heat ng capac ty s too low and/or the a r flow rate s too h gh, combust on
products may condensate, result ng n the rreparable corros on of the heat exchanger. If the heat ng
capac ty s too h gh and/or the a r flow rate s too low, an anomalous overheat ng of the heat exchanger
may occur, result ng n the act vat on of the safety dev ces and caus ng damage to the exchanger.
It has to be checked if condensation is forming inside the heat exchanger during its
functioning. This check should be performed by turning off the burner after half an hour
of continuous functioning, checking if there is any trace of humidity in the exhaust
manifold.

TRANSFORMATION GAS / FORCED GAS BURNER
Burners are factory-conf gured for operat on w th natural gas G20. The transformat on, f requ red, to
another type of fuel gas s nstaller’s respons b l ty and charge. Such transformat on may be carr ed out only
by qual f ed and sk lled workers str ctly observ ng the spec f cat ons set forth n the nstruct on manuals of
the burner and of the power ramp, f any, prov ded together w th them.

ELECTRIC CONNECTION
Electr cal connect ons should be made by qual f ed personnel and n compl ance w th the relevant
Regulat ons, us ng the ad hoc term nals. For any electr cal operat on to be performed, refer to the w r ng
d agram ncluded n th s manual and prov ded together w th the appl ance.
•Install a c rcu t breaker of the s ze requ red by the relevant regulat ons before the mach ne.
•Always connect the earth connect on of the mach ne, leav ng the earth w re sl ghtly longer than the
l ne w res, so that, should they be acc dentally torn off, t w ll be the last to be detached.
•Have author zed personnel check that the w re sect ons and the electr c plant are adequate for the
max. absorbed power spec f ed n the plate data.
•Take nto account the polar ty n the power supply connect on (phase - neutral).
•The mach ne should compulsor ly be connected to an effect ve earth ng system. The Producer shall
not be held l able for damage occurred because the mach ne s not equ pped w th an earth
connect on.
•Electr cal w res should be placed so as not to come nto contact w th hot and/or cold surfaces or
w th cutt ng edges.
•In compl ance w th the electr c Regulat ons concern ng the nstallat on, nstall a dev ce ensur ng that
the mach ne s d sconnected from the network, w th a contact open ng d stance adequate to ensure
the complete d sconnect on n overvoltage cond t ons III (Standard EN 60335-1)
•Water or gas p pes should not be used as earth connect on of the mach ne.
•Use the ded cated cable glands to nsert the supply and control w res n the mach ne.
• If you have any doubt, do not operate on the mach ne. Contact the manufacturer to rece ve further
clar f cat ons and/or add t onal nformat on.

FAN MOTOR CONTROL
In the electr c panel there s an outlet for fan motor (MV) control.
If the appl ed electr c load s lower than that shown n the table set forth hereunder, such outlet can be
used d rectly; otherw se t can be used to operate a relay and/or contactor.

A paper vers on of the w r ng d agram s ncluded n the appl ance. It s an ntegral part of these nstruct ons
and we recommend keep ng t carefully.
CHECKS
In order to ensure that the mach ne works properly, some bas c parameters should be checked. Act vate the
mach ne and:
•Check that the vent lat on un t starts after max. 30 s from the burner act vat on.
Wh le the warm a r heater s normally work ng (after approx. 20 m nutes of un nterrupted work ng), perform
the follow ng operat ons:
•Measure the a r flow, as t s cruc al to get an opt mal room heat ng and furthermore s necessary n
order to adequately cool the heat exchanger. The absence of any k nd of res stance on the a r flow
generated by the fan s essent al. Therefore, avo d any obstacles h nder ng a r supply and return.
•Check that there s no fuel leakage.
•Check that the fuel flow s correct by read ng the meter.
•Check the combust on parameters.
•Check that the nstalled safety dev ces do not operate anomalously.
•On the remote control panel, lower the set-po nt to a value lower than the room temperature and
check that only the burner turns off and that the fan un t does not s multaneously stop.
•Check that the fan works for 3 m nutes after the burner has stopped, before stopp ng as well.
•Check that the thermal grad ent s equal to the one spec f ed n the TECHNICAL DATA paragraph.
The thermal grad ent s the d fference between the a r outlet and a r nlet temperature. S nce the a r
outlet temperature s not constant through ts outlet sect on, n order to get th s value, several
temperature measurements have to be carr ed out (throughout ts outlet sect ons) and then the
ar thmet cal mean has to be calculated.
•Check that the a r pressure gauge of the burner s correctly cal brated, so that t stops f the
comburent a r s not enough - s nce th s m ght cause a non hyg en c combust on
All the checks above mentioned should be performed in all the arranged working
conditions (max and min).
