TO BE CARRIED OUT ONLY BY QUALIFIED AND

EXPERIENCED PERSONNEL.

Check that the plant room is ventilated at all times.
Frequently inspect the air inlet of the burner and

ensure that  there are no obstructions to air flow.

Flame Detection System (IRD Cell)

With the system set for normal operation, pull

out the detector probe and cover it up to cut

off light. Both LED indicators must extinguish.

The control box should switch to lockout or

attempt to re-start the sequence.

Attempt to re-start with the flame detector

covered. There must be no indication from

the LED’s after the start impulse. The burner

control box must switch to lockout at the end

of the safety interval.

Attempt to start the burner with the detec-

tor exposed to stray light e.g. from fluores-

cent lighting, a cigarette lighter or light bulb

(not daylight or an electric torch): The con-

trol box should switch to lockout either im-

mediately or at the end of the pre-purge, as

a result of stray light.
