Digital Manometer

[amy]

Hi
I was thinking about getting myself a digital manometer and wondered which people recommend, if any? I Was looking at' 608 Single Input Digital Manometer '.
I can see prices varying from 59 to 259, single nipple( input ) and double nipple?
Accuracy to 1 point and 2 points.
I have a water type gauge, just wanted the digital version.
I understand you can use these to set min pressure on gas valves easier and also for checking to see if a boiler requires cleaning( some pressure test?).
Do you ever use 2 gauges at the same time,ie one on meter other on appliance, I find myself removing from meter to appliance, to meter to another appliance--or am I doing something wrong,lol.
Thankyou.

not a big lover of digi manometers TBH, there is a purchase cost then calibration, and perhaps im just old fashioned but after 11 months of daily use is it def going to record correctly, whereas water in a manometer is either droping or it isnt, on the point of using 2 manometers ( and OK i work as a trainer now so it is all Victor Meldrew) but i wouldnt leave a manometer connected to a test point if i wasnt beside it in case it slipped off, causing a prob, either a gas leak or setting fire to an appliance

If you have a good combustion analyser, theres a chance you can use it as a manometer. Just a thought before you buy one - check!

Like yourself I have thought about getting one for Worcester flue -ve pressure test but that is all I would probably use it for.
I have had the use of the digi ones in the past and found they can fluctuate quite a bit and can be a pain to use. Especially on an outside meter tightness test during a force 9 gale. Sometimes it's better to keep it simple with an old faithful u-tube which mentioned above, does not need calibration every year.
If you are getting one the TPI 608 will do the job. Thought about getting one myself when the cash-flow problems ease up. Need start servicing load of Worcesters to justify it though.

I already mentioned keeping it simple. One Manometer at a time!

Thankyou,
The pressure test you speak of, is that a test designed to ascertain whether heat exchanger/fan assembley is ready for a clean?
This is something I have heard of here and there but no class-room tuition yet.
I saw a worcester a few weeks ago, it didn't have a flue-gas analysis point but did have a kind of nipple sticking out of the top of the casing with a screw, sometimes also seen similar with a plastic nipple cover. And if there are no flue-gas analysis points and lets say the terminal was on the roof,how would we analyse this. Thankyou.

It tells you how much air is being drawn through the heat exchanger which gives an indication of how dirty it may be without having to break into the combustion chamber. Not every boiler has this facility so it is not part of the general course. Mainly the more recent HE Worcesters avail of this to allow you to service without having to break the combustion chamber seals unless absolutely necessary.

The FGA point may be on the combustion cover case, top of boiler, or on flue as it exits the boiler. If unsure check the MI's.
If an older boiler has none, you may stick the probe in the flue terminal. If you cannot access the terminal the FGA cannot be done. You then have to revert back to basics and carry out full clean and inspection.

Is it a highflow 440 that you are referring to about the nipple with a red cap on the side of the case In turn this is connected to flexi pipe then to the flue inside the inner case.

Hello,
I found the name of the boiler, it was a worcester 24i.
The nipple on top of the casing was for testing with analyser ( correct me if i'm wrong ).
Amy.

 

[REDSAW]

yes, its at the base flange plate of the flue. fga point.

How do you go about testing gas emissions on the highflow 440 as you cannot fit a a standard probe to the nozzle.
