Got a couple of situations just wondering if any commercial guys could give me some advice on classifications.
1. Nine Hamworthy UR 430 open flued boilers connected to one flue. Think the maximum should be six.
Everything ok, burner pressure, gas rate, flue flow, no spillage with all boilers running, combustion analysis
good. Has been classified AR previously.
2. Ventilation requirement in plantroom is 2000cm at Low level, 1000cm at High Level. Plantroom has total ventilation of 4500cm but most of it (4000cm) is at high level. Does the fact that the there is enough total free airspace make it NCS? or should it be upgraded to AR?
Cheers guys
