TAC (Chapter 5 

p. 34).

Never power the appliance off while it is running

NEVER power the appliance off while it is running (ex-

cept in the event of danger, Chapter III.1 

p.  4), since 

the appliance or system might be damaged.

Routine switching on/off

The appliance may exclusively be switched on/off by 

means of the suitably provided control device.

6.2 

 PRELIMINARY  CHECKS

Checks before switching on

Before switching on the appliance, ensue that:

„

Gas valve open.

„

Appliance electrical power supply (main switch ON).

„

The fumes exhaust duct is free and correctly connected 

to the fumes exhaust system.

„

The hydraulic circuit has been filled. If this is not the case, 

fill the system according to the instructions in Paragraph 

3.3.2 

p. 23 and 3.3.4 p. 25.

„

Check on the pressure gauge that the system pressure is 

1,2 bar for Caldaria 35 and 1,5 bar for Caldaria 55.1 and 

Caldaria 100.2.

If there is no water in the system or if the system pres-

sure is lower than the minimum required pressure, 

appears on the display of the control panel (Figure 

6.2 

p. 47), while error E04 appears on the remote con-

trol (if any). When the correct pressure is restored, the 

error code disappears.
