1. Check that the system has been filled and that the boiler is not
airlocked. Ensure the automatic air vent cap is open. Refer to
Frame 23.
Note.
It is important the burner is not operated before the system is fully
vented of air. If it is necessary to operate the appliance pump to
assist venting of the air this must be done with the gas service cock
turned off.
2. Refit the boiler front panel. Refer to Frame 35.
3. Check that the drain valve (K) is closed and that the CH isolating
valve (E and J) are OPEN.
4. Check that the electrical supply is OFF.
5. Check that the boiler mode control knob (B) is off.
6. Check that the gas service cock (H) is OPEN.
7. Slacken the screw in the inlet pressure test point (G) and connect
a gas pressure gauge via a flexible tube.
8. Switch the electricity supply ON and check all external controls
are calling for heat.

9. Set the CH temp control (A) to max and turn the mode control knob
(B) to ON. The boiler control should now go through its ignition
sequence until the burner is established.
10. If the boiler does not light after 5 attempts the boiler will lock out
and display fault code
Frame 37). The boiler will repeat its ignition sequence. If reset
occurs 5 times within 15 minutes then
is removed this will be reset.
When the burner is established the BLUE 'Burner On' neon (D)
will be illuminated, the LED display (C) will show status .
11. Ensure that with the boiler operating the dynamic gas pressure
is able to obtain maximum output. Refer to Table 2.

The gas input to the burner is regulated by the gas
valve according to the air flow produced by the fan.
It is NOT user-adjustable. Any interference to sealed
settings on the gas valve will adversely affect operation
and render our warranty void.
For additional gas supply information refer to "Gas Supply"
on page 8.

The user control has one neon and one display to inform
the user about the status. The display will show the status
of the boiler. The neon will show the status of the flame.
If no flame is detected the neon is off. When the flame is
detected the neon will be lit permanently.
Below is a list with display function in normal operation.
Standby, no demand for heat present.
Boiler is active for central heating or hot water.
Boiler is active for boiler frost protection.
Boiler is in lockout for a specific error. Display will be
blinking, alternating with a number or letter to show
which error is detected.
Boiler has a fault for a specific error. Display will be
blinking, alternating with a number or letter to show
which error is detected.
Note: Boiler frost protection - boiler fires if temperature is
below 5 degrees C.
Note. The boiler incorporates a fan overrun cycle which
MUST NOT be prematurely interrupted by isolation of the
mains electricity supply.
