Boiler flue temp readings?

[macka09]

Hi guys. Today I’ve noticed when taking an fga the flue temp is coming up as a minus even though the boiler had been running all day. Any particular reason that it would be like that?
Also had a +6.50mb on a fan pressure test. Boiler was only one year old.

Porobesin the right ports ?

Yer I believe so. It’s a kane 450. I’m using the tf ports.

Is your fga in need of calibrating?

No it’s in date until next year.

To geta "+", you must have the tube on the wrong connector?. Or the fan is running backwards

Ha. Surely it wouldn’t ignite if that’s was the case?

I think we can assume he has the tube on wrongly

I think you are either using the FGA wrong or it has gone sque-if and needs attension/recalibrating. Try it out on your own boiler and compare the readings.

Yer even on my own boiler the temp readings are minus. Fan pressure was a minus reading though so that’s a bonus
