Relight the main burner and allow the system to warm up.
There should be no undue noise in the system and no pumping
over of water or entry of air at the open vent.
Allow the system to reach maximum temperature and check for
water soundness.
The burner should then be turned off and the system drained,
as rapidly as possible, to complete the flushing process. Refill
the system, heat up, vent and check again for water soundness.
If the side panels are to be fitted, remove the outer case. (Fit by
fastening to the outer case using the securing screws, see
diagram 6.5.)
Refit outer case and controls cover.
