Flue height is fine. Manufacturers instructions state ' fit the flue restrictor into a class 1 chimney or 'good' class 2 chimney if spillage is detected then remove restrictor, no spillage was detected but excessive flue pull was which was causing flame lift which is why restrictor must have been fitted.
It must be a really good pre cast flue ( unusual really).

So you are saying the restrictor is in place , I thought you were asking if a restrictor could be fitted?
Minimum flue heights are a calculation based upon flue size/pull/spillage , or............... in your case whether restrictor may or may not be fitted.

Sorry yes restrictor is in place, customer called to have fire serviced previous gas fitter had fitted restrictor due to excessive flue pull but spillage test was perfect.
Was just curious because because never seen one fitted to a PCF before.
But MF instructions due state to fit the restrictor into a 'good' class 2 chimney unless spillage is detected.
