ROUTINE YEARLY VERIFICATION OPERATIONS

COMPONENT:

VERIFY:

CONTROL/INTERVENTION 

METHOD:

FL  

(domestic hot water 

priority flow switch 

( 2 )

Is the minimum domestic hot water

flow rate 3 l/min.? 

The burner must ignite with an 

intake above or equal to: 3 l/min.

VG 

(Gas valve) 

( 3 )

Does the valve modulate properly? 

Open a hot water tap at maxi-

mum flow rate and then at min

-

imum. Make sure that the flame 

modulates.

SR (heating sensor)

( 11 )

 

SS (domestic hot water sensor) 

( 1 )

SSR (return sensor) 

( 22 )

Do the sensors maintain the 

original characteristics? 

12571 ohm at 20° C / 1762 ohm 

at 70° C.

Measurement to be taken with 

the wires disconnected (see 

table Res/Temp).

E ACC/RIV.  (ignition/detection 

electrode) 

( 4 )

Does the discharge of sparks before

putting the boiler in safe conditions last 

less than 10 sec.?

Detach the electrode ionisation 

wire and check the securing 

time.

TL (anti-overheating 

limit thermostat) 

( 10 )

Does the TL put the boiler in safety 

conditions when overheating?

Heat  the TL  until  it  intervenes 

at 95°C and check that it inter-

venes at 95°.

DK (safety pressure switch 

against water deficiency) 

( 13 )

Does the pressure switch block the 

boiler

if the water pressure is below 0.4 bar?

Without request: close the shut-

off valves of the heating circuit, 

open the drain valve to make the 

water pressure decrease. Before 

pressurising again, check the 

pressure of the expansion vessel.

Expansion vessel 

( 8 )

Does  the  vessel  contain  the  right 

amount

of air?

Check the pressure in expansion 

vessel  (1  bar  when  the  boiler 

is  empty).  Pressurise  the  boiler 

(open  the  pump  automatic  vent 

valve).  Open  the  heating  circuit 

closing valves.

Condensation drain trap 

(26)

Has the trap got deposits on the 

bottom? 

Clean the trap with water.

Domestic hot water flow rate 

Filter in cold water inlet 

( 2 )

Clean  the  filter  with  limescale 

remover.

Heat exchanger body 

(24 )

1) Measure the Thermal Capacity 

using a meter and compare the val

-

ue with that contained in table 3.12. 

The data measured indicates if the 

exchanger needs cleaning.   

2) Check that the space between 

the rungs of the exchanger are not 

clogged

 

It is recommended to use the 

products purposely created by 

Unical  (see system protection 

ACCESSORIES sect. in the 

domestic price list), being care-

ful to wash the area with most 

rungs  first  (lowest  part  visible 

from above) and then the upper 

part if necessary.

Burner 

( 5 )

Check the state of cleanliness of the 

burner mesh

Remove  any  deposits  using 

compressed air, blowing from 

the mesh side.
