i gave the boiler 'at risk'

[diamondgas]

should have been covered in your CPA1 (if you have done it yet) and if not i would be very wary of doing ambient air test and recording results someone somewhere would/could question the integrity of the test and interpretation of results, but briefly (at this time of night) hold probe 2m above ground level and take reading at 1 minute intervals and assess what the readings are and make a decision on whether they are above safe levels, done with appliances all off then on to see if there is an ingress of CO from somewhere else (haha i did say briefly didnt I)

Thak you for the briefness 'kirkgas' .. for those. my self included, who do not come across that many incidence where the need to check for CO is neccessary, your imput is appreciated

I worry that newbies to this proffession are to scared to experience the reality of what exists out there and live to much to the rules dictaded by the bodies that be.........!
