Final Adjustments

1) Use a pressure gauge to check the inlet and burner
pressures. See the Data Badge for figures.
2) Turn the boiler on and allow to run for 10 minutes.
3) Check that the inlet pressure is 20mbar.
4) Check that the burner pressure is in accordance
with the information on the boiler data badge.
5) If burner pressure adjustment is required turn the
pressure adjusting screw anti - clockwise to
increase pressure or clockwise to decrease.
6) Check at the gas meter that the gas rate is correct.
7) Shut down the boiler, remove the pressure gauges,
re- fit the screws and check for gas soundness.
8) Stick the self adhesive arrow (from the literature
pack) onto the data badge to indicate the
appropriate burner setting pressure
9) Re-fit the controls cover and secure with the screw
previously removed.
Control Thermostat
At its minimum and maximum settings, the thermostat
should control the water flow temperature at
approximately 57°C - 82°C.
Set the temperature control knob to 'O' Standby and
check that the main burner shuts down.
Overheat Thermostat
The overheat thermostat is pre-set and no adjustment is
possible. It will require manual re-setting if an overheat
condition occurs (the LED will go to flashing Red).
The re-set button is located on the controls assembly.
Other Boiler Controls
No further setting or checking is necessary as all boiler
mounted controls are designed so that if a fault should
occur they will fail safe.
External Controls
Check that any other external controls connected in the
system, such as clocks or thermostats, control the boiler
as required.

Instruct the User

On completion of the installation, the installer should
demonstrate the operation of the boiler and its
associated controls. Also hand over all the instructions.
3.4

Advise the User

1. If a timer is fitted, set the time and programme the
required settings. For a wall mounted programmer,
see separate programmer instructions. For the
Suprima timer, see the timer Instructions for Use
fitted to the controls cover door.
2. Hand the Instructions for Use, these Installation &
Service Instructions (and the programmer
instructions) to the User and instruct in the safe
operation of the boiler and controls.
3. Advise the User of the precautions necessary to
prevent damage to the system and to the building in
the event of the system remaining inoperative
during frost conditions.
4. Advise the User that for continued efficient and safe
operation of the boiler it is important that adequate
servicing is carried out at least once a year by a
Potterton Myson Service Engineer or a C.O.R.G.I.
Registered Installer.
5. Leave a permanent card attached to the boiler
giving:
a. Name and address of installer.
b. Date of installation.
c. A wiring diagram of the external control circuit.
