This test is to determine if the heat cell requires cleaning/
attention
When fitted with the optional diverter valve (not
supplied) and running in performance test mode, the
boiler will only operate the central heating circuits.
If fitted to an S or Y plan system, the system must only be
run in central heating mode.
This is to allow sufficient time for this part of the
