No CO test for gas fire when serviced?

[Help4me]

Hi,
Could someone please tell me if a CO test should be done to detect any small leakage, on an old gas fire with back boiler, when serviced?

Thanx

Thanx. I wish the service had told me that then. When I asked him about testing for CO he just looked up at the old electric alarm on the ceiling, and said 'that will detect any'.
I rang an official org about the alarm we have, as we rent the house and nobody ever checks it inside. I was told that it's old, and nobody puts them on the ceiling anymore. I was advised to buy one and put it on the wall above the fire.
I was doing my research about alarms and it's the general opinion that it shouldn't be placed near the fire. Why is this, because I would have thought if it was placed near to the source, the sooner the CO would be detected?

Hi, a CO alarm shouldn't be placed next to the fire because 1. When appliances with chimneys/open flues first fire up, the chimney can be cold and take a few minutes to warm up & work properly [ spillage into the room.]

2. The heat from a fire convects the heat into the room out a grill which rises & circulates to the back of the room, therefore if position wrongly at the side & high up, behind the fire, it would be the last place to pick up fumes.

Best advice is to follow the manufactures instructions.

I had loads of back boilers in my rentals all changed out for safty issues never trust tenants ,
& we serviced loads of back boilers they may recomend the gas analysis but its not needed .
Clean it properly burner pull jet out clean it ,clean heat exchanger clean general muck with vac.
get flue hot & use a smoke bomb their you have it .
Fire needs a good clean but every few years pull out jets & clean do a spillage test & their you are .
My last Corgi inspection was a back boiler he didnt ask me to get the analyser out & I didnt offer he signed me off .
Any way if you have a toy & want to use it fill your boots .
If its a new combi then you cant realy do it properly with out one a vaillant or viessman you dont open the heat exchanger unless theres a problem you use a analyser .
