To get the burner running correctly loosen the locking screw and
very slightly
move the jet carrier
out of the burner tube, tighten the screw, light, wait 30 seconds and observe the flame. Turn off the
gas and allow the burner to cool before repeating the process. The burner is set correctly when
there are
little blue jets
dancing on the ceramic and (almost) no yellow flame above them.
The burner can now be installed beneath the boiler cylinder when fine tuning may be necessary.
The lock screw can then be securely tightened – make a note of the position of the jet carrier in case
it needs to be removed.
Lighting the Burner
WARNING: Before lighting read the section on troubleshooting and be aware of potential
problems. If the gas system is not operating correctly, shut it off immediately or damage may
result.
Be aware that Butane is heavier than air and small pockets of gas can collect around the
canister/tank during connection/filling. Also Carbon Monoxide can be produced by the burner, so
always use in a well ventilated location, preferably outside.
Use heat resistance gloves when lighting or handling the burner while still hot.
