the ‘Burner On’ indicator going out and the lighting sequence
starting up, as follows:
1. Fan continues to run and then switches off / slows down.
2. After approximately 5 seconds fan restarts / speeds up.
3. After a short period sparking begins and the boiler attempts
to relight.
After shutting off the gas, the boiler will attempt to relight twice
before shutting down. The following illumination will happen
with the LED on the front of the control panel, "Reset" permanently
ON and "Burner Lit" flashing fast (8 Hz).
If the above lighting sequence fails, refer to section 9 - Fault
Finding.
To continue, turn the gas service cock ‘On’, see diagram 6.1.
To restart the lighting sequence, turn the temperature control
knob to "O" then fully clockwise to "Max". After approximately 10
to 15 seconds the boiler will begin its ignition sequence.
During Normal Operation when the boiler switches ‘Off’, the
burner will go out. The automatic lighting sequence will work
again when heat is required.
6.4 Testing - Gas
With the boiler on proceed as follows:
Test for gas soundness around the boiler gas components
using a suitable leak detection fluid, in accordance with the
current issue of BS6891.
Check the burner gas pressure at least 10 minutes after boiler
has lit, refer to Data Label, see diagram 1.2 and 1.3.
If necessary adjust the gas pressure to obtain the required
setting turning screw anti-clockwise, to decrease pressure, see
diagram 6.1.
Should any doubt exist about the gas rate, check it using the gas
meter test dial and stop watch at least 10 minutes after the
burner has lit, making sure that all other gas burning appliances
and pilot lights are off.

is for guidance only, dependent on the heat setting.
Turn the boiler temperature control fully anti-clockwise to “0”.
Isolate from the electrical supply.
Remove the pressure gauge from the test point and refit screw,
making sure a gas tight seal is made.
When the boiler temperature control is turned to the “0” position,
by hand, wait at least 30 seconds before turning On again.
There may be an initial smell given off from the boiler when new,
this is quite normal and it will disappear after a short period of
time.
6.5 Testing - All Water Systems
Allow the system to reach maximum working temperature and
examine for water leaks.
There should be no undue noise in the system.
The boiler should then be turned off and the system drained off
as rapidly as possible, whilst still hot.
Refill system.
6.6 Open Vented System
Ensure there is no pumping over of water or entry of air at the
open vent above the feed and expansion cistern.
Diagram 6.2
Diagram 6.3
6.7 Adjustment - Fully Pumped Open Vented
System
When commissioning the system the boiler should first be fired
on full service, that is, central heating and domestic hot water.
Adjust the pump to the system design setting, then balance the
system, making adjustments as necessary.
6.8 Completion
Adjust the boiler temperature control and any system controls
to their required settings. In addition it is necessary to complete
the "Benchmark" logbook.
For 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.
Fit the bottom plinth panel and secure with two dog point
screws, see diagram 6.2.
Finally fit the front panel by hooking under front of top panel
locating on the two studs and securing at the bottom on to the
bottom plinth panel with two screws, see diagram 6.3.
Testing Flue Gasses:
If any doubt exists that the flue products
are not exhausting correctly. Investigate by the use of a gas
analyser (FGA).
