Grant Euroflame

[crossdevil]

i have a grant euroflame, which i have recently serviced myself. (I did what the manual told me etc). I was told i also needed to check co2 so managed to borrow a analyser from a friend of a friend, the co2 seemed ok, but i noticed the flue temp was quite a bit higher than it should be. Is it going to cause me a problem and should i be doing anything else?

How about the CO?

 

[crossdevil]

co was 17ppm

 

[crossdevil]

sorry, never had my specs on for co read -7

If you are concerned about Flue Gas Temperature why not share the reading with us, so we can comment/advise, a Euroflame should run at approx 180'c - 200'c +/- 20'c or so

How do you get a negative amount of CO? I always thought 0 was as far down as is possible.

 

[Boilerman2]

Some Electronic Analysers do give a Negative reading on CO, this should be read as ZERO

 

[twgas]

I wouldn't trust a FGA that showed a negative reading, unles I had zeroed it in contanimated air.

 

[crossdevil]

flue gas is 262'C, is that high or within the tolerances

Is the oil pressure and air setting correct? You might be firing to much mixture into the combustion chamber?

 

[Boilerman2]

Some of the Older Maester Analysers frequently gave negative CO readings.

262'c is very high for a Euroflame, sounds like it may be over-firing, has somebody set it up incorrectly i.e a 50/70 boiler set up to 70/90 specification?

 

[crossdevil]

it is a 70/90, the oil pressure was 8bar, co2 was 11.5%, 02 was 6.6%

Nozzle??

Nozzle??

Pretty sure its 0.75, 80EH. If the angle is wrong ie. 60EH it would give a different cone shape, thus the flame would touch on the chamber.

 

[crossdevil]

no i put in a 0.75, 80EH
