I've been shaddowing my Gas Safe buddy while waiting for the start date of own training.
He was testing a CX30 which showed xxMb at the test point with the boiler running on the Hi (max) setting for xx mins. Though not ideal, but the MI appears to say down to xxMb is acceptable (confusingly worded though!). I understand this was a pass. I seem to recall that was a drop of xMb from the meter.
What concerned my buddy, and used up quite a few hours of retesting etc, was the max gas rate test. (It did not help having a prepayment meter BTW!) MI says max gas rate is xm cube/hour. 1st test result was x and second test was x. He quoted a +x% / -x% tolerance as being acceptable, and as it was within these limits, I struggled to really understand the issue. (CP30 not issued/ return visit planned)
He mentioned gross and net which I've not yet swatted up on, and I've since determined the CV for that day was xx if that info is needed. MI says max. heat input nett Q for DHW is xxKWh and for CH is xxkWh.
Perhaps me looking over his shoulder and asking too many questions was the route cause of the problem! Rather than me bugging him again, could someone please explain if this is indeed a pass or fail and what the test is trying to achieve as I could not find out in this forum?
Flue gas analyser tests all easily passed BTW.
