Trouble-shooting
The gas pilot will not ignite or stay lit

Ensure the gas is turned on at the appliance and the meter / cylinder.

Check for blockages (especially after the pressure test point connection).

Is there a strong spark being generated, If not firstly check that the spade connection is
push fully into the pilot assembly. If still issues check that the spark generator has not
been bent in transit
– if it has, bend the metal generator so the spark is hitting above
the pilots gas outlet not below. The spark generator should be ideally10mm from the
pilot head

The pilot gas button must be held in for at least 20 seconds once the pilot is
established to ensure the safety thermocouple is heated sufficiently.

Ensure that both ends of the TTB connection cable are firmly connected and not
damaged. If no damage, look at tightening the thermocouple connection to the splitter
(see page 10). You will need an 8mm spanner.

Make sure that the brass interrupter (connects thermos-couple and TTB to valve
–
shown on page 9) is not loose. You should not be able to move the interrupter by
hand. Any break in the following circuit will cause the pilot not to stay alight as the
electrical charge from the thermos-couple needs to arrive at the valve to keep it lit:

Take care not to overtighten the interrupter unit into the valve as this can twist the
spade connections. As you look at the back of the interrupter the spade connections
should look like two vertical lines (if they are more like 45°C then it
’s too tight)

Ensure that the pilot head, injector and burner ports are not obstructed or blocked and
are free from any dust or dirt.

Ensure gas pressures and flow rates are correct, as this will prevent ignition of the
pilot. An indication of high pressure can be a whistling sound from the pilot.

Ensure that the pilot assembly has not been damaged in transit. Be sure to check the
gap between the thermocouple and electrode is sufficient and that the spark is not
arcing elsewhere, this is a very delicate device.

The pilot flame should burn with a strong blue flame. The flame should be focused on
the tip of the thermocouple.
