ting request. If at the same time

there is a request for domestic hot

water the lamp switches off.

Burner ON lamp (Green) (F)

When this  lamp is illuminated it

indicates that the burner is on,

both for central heating or for do-

mestic hot water production.

Burner lockout  warning lamp

(G)

The function of this lamp is to si-

gnal that the burner’s control is in

lockout position, due to

- lack of gas or

- H.L. thermostat  cut-out due to an

over-heating of the boiler (95°)

In the first case, if the burner does

not fire, it will be necessary to

verify if the gas gate valve is

open.

In the second case due to a lack

of circulation or to an excessive

scaling  deposit in the heat

exchanger the H.L. thermostat

could shut down the boiler at 95°C.

Reset Button (L)

In the first case, which we pre-

viously described, in order to reli-

ght the boiler it will be necessary

to press the button 

(L)

 using a nail

or something like that.

In the second case, before pres-

sing the button 

(L)

, it will be ne-

cessary to wait for the tempera-

D.H.W. temperature control

(C) + No Frost (Only for IVEN

RTN / RTFS when combined

with an external D.H.W. tank)

If the knob is set within the

range indicated by the arrow

on the illustration it means is

possibile to adjust the D.H.W.

temperature from a minimum

of 25°C to a maximum of

57°C.

The reference to the knob in

the position points out that the

boiler's sanitary circuit is not

in operation (in that case the-

re is no production D.H.W.). If

in the mean time the B  knob

is in the position        the anti-

freeze protection of an exter-

nal D.H.W. tank is activated.

Note: for IVEN RTN/RTFS

when a D.H.W. storage tank

is not fitted, the knob (C)

must be positioned and

must stay onto the

symbol

Power ON lamp (Green) (D)

When this  lamp is illumina-

ted it indicates that the boiler

is connected to the mains sup-

ply.

CH request  lamp (Green) (E)

If this  lamp is illuminated it

indicates that there is a hea-

ture of the H.L. thermostat 95°C

to drop at least of 25 K.

Chimney-sweeper push button

(H)

This button allows the starting of

chimney-sweepers function, that

is to say that the boiler works at

maximum power (or at minimum

power) in order to allow adjust-

ment’s operations and combu-

stion's tests.

By pushing one time the button,

the boiler works at maximum ou-

tput. (              )

By pushing the button while the

boiler works at maximum output,

the boiler will work at minimum ou-

tput. (                 )

To go back to the boiler normal

operation switch OFF and ON the

boiler via the A switch.

SWITCHING

ON / OFF

For the operation of the boiler in the 

WINTER

mode the knob 

''B''

 reference must be posi-

tioned within the range indicated by the arrow

on the figure shown above.  The limit of the

arrow corresponds to the minimum and maxi-

mum temperature values of 45°C and 78°C.

SWITCHING ON

D.H.W. temperature adjust-

ment range for the models:

IVEN 04 CTN/CTFS

D.H.W. temperature adjust-

ment range for the models:

IVEN 04 RTN/RTFS

when conbined with an

external D.H.W. tank.

Note: If a room thermostat is fitted, set it to

the desired temperature.

SWITCHING OFF

Switch off the boiler by acting on the switch

''A''

.

For the operation the boiler in 

SUMMER

 mode,

only for domestic hot water production, the

knob 

''B''

 reference has to be positioned on

the SUN        and the D.H.W. temperature

value has to be adjusted using the knob 

''C''

.

Shut off the gas cock upstream the

boiler in case a prolonged inactivi-

ty period of the same is expected.
