Carbon monoxide poisoning & the Isar

[MiggyMod]

I was wondering if anyone else has had problems with low level c o poisoning with the Ideal Isar?
Family all had lowish levels of co in bloodstream & symptoms, but boiler not "appearing" to be releasing gas into house.
The flue onto the heat exchanger wasn't fitted properly but the escaping gas didn't seem to be escaping the unit in the short term. Any ideas?

ps. no other gas appliances in house & the adjoining house was clear n

Do you mean the elbow was'nt sealed properly (assuming it was a standard flue) or was there something inside the boiler not sealed ?

Any smokers in the house?

Pretty easy on an isar, the insulation board falls on the heat exchanger and melts the back panel or the sump gets virtually blocked and the co goes through the roof so any leak on the flue or path for fumes outside to reenter the property would cause co incident

where the elbow screws onto the combustion chamber (heat ex), the screws were threaded so the flue gases were leaking back into the unit

Would an Isar work long enough for this to happen

are you talking about the flue elbow? if you are, then why Screws there should only be 1
u shaped clamp slots into 2 tags on top of casing and a single screw is then put in front slot of clamp which should then be tapped backwards so that the screw is at the front and clamp is tight against elbow.

Sounds like an installation fault methinks
