In calculating the lengths of the pipes, the

TWIN PIPE

maximum length “L” must also take into

SYSTEMS

consideration

the

values

for

the

exhaust/air intake end terminals, as well

 

 

as 90° elbows for coaxial systems.

 

 

The C52 types must comply with the

 

following requirements:

 

 

 

1 -

The exhaust/ air intake pipes must

 

 

have the same diameter of ø

80 mm.

 

2 -

If elbows are to be inserted into the

 

 

air intake and/or exhaust system, the

 

 

calculation of the overall length must

 

 

take into consideration the values for

 

 

each elbow, see the FL U E

PI P E

 

 

ACCESSORIES MANUAL.

 

 

 

3 - The exhaust pipe must protrude by at

 

 

least 0.5 m above the top of the roof

 

 

in the event that it is located on the

 

 

opposite side to the side with the air

 

 

intake (this condition is not obligatory

 

 

when the air intake and exhaust are

 

 

located on the same side of the

 

 

building).

2.10ROOM THERMOSTAT CONNECTION

To connect a room thermostat, it is necessary to:

1. - Open the control panel as indicated in section 3.3.

2.- Remove the link “A” from the terminal block on the reverse of the control panel.

3.- Insert the thermostat cable through the cable grommet and fasten it by means of the cable-clamp provided.

4.- Then connect the thermostat wires to the terminal block.

5.- If a remote time clock is to be fitted, disconnect the integral time clock from the P.C.B.

6.- Using a volt-free switching time clock, connect the switching wires from the time clock following points 1-4 above.

7.- If using an external time clock and room thermostat, these must be connected in series as points 1-7 above.

Note: Only a two-wire type room thermostat can be used.

An anti-frost device is built-in to the appliance’s electronic regulation system.
