13 Remove and discard the conventional flue flexible

air tube supplied with the boiler from the burner air

spigot retaining the clamp.

Extend the flexible air tube supplied with the flue

kit over the top of the boiler water jacket, passing

the tube under the control panel and across the

front of the boiler. Locate the end of the tube over

the burner air supply spigot and secure using the

clamp previously removed.

Clip the tube into the hanging bracket on the flue
