the alarm “AL 02”. 

 Increase the system pressure to 

between 1.0 and 1.2 bar (use pressure 

gauge, fig 22/a) using the external 

filling loop. The boiler will automatically 

resume operating.

– 

C.H. SENSOR ERROR ALARM 05 

 

When C.H. sensor (SM) is open or 

short circuited, the boiler will not 

function and the display will show the 

alarm “AL 05”.

– 

LOCKOUT ALARM 06 (fig. 22/b)

  If the flame control has not detected 

the presence of the flame after a 

complete ignition sequence, or for any 

other reason the card cannot “see” 

the flame, the boiler will stop and the 

display will show the alarm “AL 06”.  

Press the key

   

of the controls to 

start up the boiler again.

– 

SAFETY THERMOSTAT ERROR 

  ALARM 07 (fig. 22/c)

  Opening of the safety thermostat will 

turn off the burner, the display will 

show AL07. If the problem persists for 

more than one minute, the boiler will 

stop and the red LED will turn on. 

  Press the key

   

of the controls to 

start up the boiler again.

– 

FLAME DETECTION ERROR ALARM 08 

  If a flame is detected when one should 

not be present, the boiler will stop and 

the display will show “AL 08”

– 

D.H.W. SENSOR ERROR ALARM 10 

  When D.H.W. sensor (SS) is open or 

short circuited, the boiler function 

in C.H. and DHW and the display will 

show alarm “AL 10”. Replace the sensor 

because the message disappears.

– 

ACTIVATION OF THE EXHAUST 

TEMPERATURE SENSOR ERROR “AL 

13” (fig. 22/d)

 

  The activation of the exhaust fumes 

sensor causes the boiler to stop and 

the display will show AL 13.

  Press the key

   

of the controls to 

start up the boiler again.

– 

EXHAUST TEMPERATURE SENSOR 

  ERROR “AL 14”

  When the exhaust fumes sensor is 

opened or short-circuited, the boiler 

stops and the displays shows anomaly 

AL 14.

– 

FAN ERROR “AL 15”

  If the fan speed is not within the rated 

speed range , the display will show 

“AL 15. If the problem persists for more 

than two minutes the boiler will stop 

for thirty minutes and then attempt to 

resume working.

COMMISSIONING AND 

 ROUTINE 

SERVICE

Commissioning and servicing can only 

be done by a qualified engineer.

4.7.1   Commissioning

PLEASE NOTE: The combustion for this 

appliance has been checked, adjusted 

and preset at the factory for operation 

on the gas type defined on the appliance 

data plate. 

However it is advisable to check 

for correct combustion having first 

checked:

-  That the boiler has been installed in 

accordance with these instructions.

-  The integrity of the flue system and 

the flue seals.

-  The integrity of the boiler combustion 

circuit and all the relevant seals.

The following procedure should be 

done after installation a gas purge and 

tightness/drop test have been made.

Ensure that the auto air vent (12 fig. 3) is 

opened, turn the electrical supply on.

With the boiler on standby fill the system 

and pressurise to 1.5 bar.

Ensure that the pump has been manually 

rotated.
Open the gas cock, press the “  mode 

key” (fig. 12).

Check the operational (working) gas 

inlet pressure.

Set up the boiler to operate at maximum 

rate as described in 4.5.1 (Chimney 

sweep]).

With the boiler operating in the maximum 

rate condition check that the operational 

(working) gas pressure at the inlet test 

point (see fig 16 item 1) is 21 mb +/- 2 

mb.

Ensure that this inlet pressure can be 

obtained with all other gas appliances in 

the property working.

The boiler will attempt to light.
Press “  mode key” (fig. 12).

The burner will extinguish.

Turn on a DHW tap fully (preferably the 

bath tap).

Set the controls to the required values as 

shown in the user guide.

Complete the Benchmark sheet enclosed 

in this manual.

Explain controls and operation to the 

user.

Leave all documentation with the user.

4.7.2  PAR 15 maximum Heating Power

PAR 15 (parameter 15) is set as default 

at 81% of the maximum boiler heating 

output. This value should be adjusted to 

correctly represent the actual heating 

requirement for the installation.

4.8  

ROUTINE SERVICE

To comply with the conditions of any 

extended warranty offered and to 

ensure continued safe and efficient 

operation, the boiler must be serviced 

at regular intervals, at least once a year. 

This service must be recorded in the 

Benchmark section of this manual.

It is the law that a competent person 

such as a Gas Safe Register registered 

engineer, must carry out any service 

work.

4.8.1   Combustion Check (fig. 23)

Competence to carry out the check of 

combustion performance.

PLEASE NOTE: BS 6798: 2009 

Specification fro installation and 

maintenance of gas-fired boilers of 

rated input not exceeding 70 kw net 

advises that:

* The person carrying out a combustion 

measurement should have been 

assessed as competent in the use of a 

flue gas analyser and the interpretation 

of the results;

* The flue gas analyser should be one
