12.9 Completion

Fit the boiler module front panel, see diagram 8.2.
Fit the tank module front panel, this is a push-fit.
Ensure that the magnetic lighting instruction label is placed on

the surface of the boiler casing
GB: It is a requirement that the “Benchmark” Installation,

Commissioning and Service Record is completed and left with

the user.
IE: it is necessary to complete a “Declaration of Conformity” to

indicate compliance to I.S.813. An example of this is given in

the current edition of I.S.813.

12.10 Instruct the User

● Demonstrate, then instruct the User about the lighting

procedure and heating system controls operation.
● Advise that to ensure the continued efficient and safe

operation of the boiler it is recommended that it is checked

and serviced at regular intervals. The frequency of servicing

will depend upon the installation conditions and usage, but in

general, once a year should be enough.
● Draw attention, if applicable, to the current issue of the Gas

Safety (Installation and Use) Regulations, Section 35, which

imposes a duty of care on all persons who let out any property

containing a gas appliance in the UK.
● The user shall not interfere with or adjust sealed

components.
● It is the Law that any servicing is carried out by a competent

person approved at the time by the Health and Safety

Executive.
● Advise the user that, like all condensing boilers this

appliance will produce a plume of condensation from the flue

terminal in cool weather. This is due to the high efficiency and

hence low flue gas temperature of the boiler.
● Advise the user of the precautions necessary to prevent

damage to the system, boiler and the building, in the event of

the heating system being out of use during frost or freezing

conditions.
● Advise the user that the permanent mains electrical supply

SHOULD NOT be switched off, as the built in frost protection

and pump saver program will not operate.

12 Commissioning

● Advise the User if the mains electricity and gas are to be

turned off for any long periods during severe weather, it is

recommended that the whole system, including the boiler,

should be drained to avoid the risk of freezing.
Note: Sealed System: Contact your installation/servicing

company as draining, refilling and pressurising MUST be

carried out by a competent person approved at the time by the

Health and Safety Executive.
● Leave these instructions and the ‘Benchmark’ Installation,

Commissioning and Service Record with the user.

12.11 LPG CONVERSION

Do Not operate the boiler without water.

During the conversion to Propane use of a suitable flue gas

analyser is necessary.
Ensure that the appliance supply pressure = 37mbar.
(1) To access the gas valve you will need to remove the

silencer tube, see diagram 13.7 and section 13.4.

(2) Refer to diagram 13.13 and turn the gas valve throttle

fully clockwise using a small flat blade screwdriver.

(3) Turn the throttle back anti-clockwise by 2

1

/

4

turns.

(4) Ensure that the gas analyser is set to the correct fuel

setting - Propane.

(5) Attach combustion analyser to the combustion test

point. See diagram 13.1.

NOTE:

Before measuring combustion the silencer must

be replaced.

(6) Turn on the gas service isolation valve, see diagram

12.1.

Turn on the electrical supply, the appliance will begin the

ignition sequence.

Monitor the combustion reading and after 5 mins at max

rate, the reading should be:-

G31 - 10.2% ± 0.5 case on, 10.0% ± 0.5 case off after

5 minutes.

To achieve maximum rate (input) press the “reset”

button on the controls fascia, release and immediately

press and hold in the “+” button. After approximately 5

seconds “Hi” will be displayed.

Pressing the mode button when “Hi” is selected will

force the boiler to maximum rate, the display will flash

between “Hi” and the “default display” this will indicate

the boiler has been forced to maximum.

If adjustment proves necessary then proceed as follows:

Adjust the maximum rate CO

2

by turning the throttle

anti-clockwise to increase, clockwise to decrease, see

diagram 13.13.

NOTE:

Adjust only in very small increments (approx.

1

/

16

turn) and wait approx. 1 minute after each adjustment

until the value stabilises.

To exit the check sequences press the “+” button, this

will reset the boiler to the default display.

(7) Remove analyser probe from the test point and replace

the cap.

(8)

IMPORTANT: Fit the LPG conversion label supplied

in the documentation pack to the base panel

alongside the data label. Ensure the silencer is fitted

and front panel replaced.
