Dwyer model 25 mark II???

Magnahelic model recommended?

Parts list recommended?

Yeah yeah...I’ve done the searches. It’s all there but don’t have time at the moment to look and may not have time tomorrow. Got to get this ordered tomorrow.

Parts list and suggestions for a clean looking install? Thanks gang.

Mine is a 2000-00c. I used high temperature 3/16 ID silicone tubing with a bulkhead connector through my fire door (stoker).

Next questions...

Do I install manometer pick-up in the ash pan door, or the stove pipe?

If the stove pipe, before or after the damper?

For a hand fed stove, the manometer goes in the stovepipe between the stove and the baro...

Don't have a barometric damper. Have a stove pipe damper that is only used for wood burning, not for coal.

However, I asked the question for this reason. The stove has a built in sliding damper in the top of the stove that I do/will use with either fuel.

If it was me, I would want to know the pressure that the fire chamber is feeling. For most, the stove pipe would be fine. But in your case, with a damper at the breech of the stove it won't be the same. I would tap the fire box for a manometer reading.

I'm trying to research this as well. Thanks for replying guys. Just takes time going through all the threads. I've read most of them several times, but can't seem to recall anything I have read. Go figure. I take Ginko Biloba for my memory, but for the life of me I can't remember where I put it. :lol:

That requires drilling and tapping the stove somewhere, right? I assume somewhere just above the level of the coal? What about the ash pan door?

The 354 manual has instructions to put it in the stovepipe...

Looks like I have a couple of choices here...
https://www.globaltestsupply.com/product/dwyer-ma ... R%20-%2025

-or-

https://www.ebay.com/sch/i.html?_nkw=dwyer+manome ... noapp=true

Would you guys trust these off of ebay?

What about the 2000HA? (High Accuracy)

I'm going to get the 25 Mark II, but I plan on getting a Magnahelic like the one you have or the one I mentioned. Would like to make a nice wooden mount/clock type install here at home.

I may even opt for something digital and portable/handheld in case I want to check a stove/chimney outside the home. Haven't really looked into them. Not wanting to break the bank, but something to fit the portable/handheld and digital while economical.

Does anyone know of a manometer that can be monitored via phone app?

I bought mine used from eBay 9 or 10 years ago... Less than $25 delivered.

I can live with the scratch on the face for that price!

HA is probably overkill for burning coal, but if the price is within $10 or so, why not?

This is a better link than the “Manometer Install” link, which has too many pages to sift through with too much info on barometric dampers if you’re just looking for a way to install your manometer to your stove pipe. This link is better, in my opinion... Got a Manometer - Now What

Sorry for the redundancy of my posts both here and in the link. I told you I was forgetting things. 😂

Just ordered a Dwyer Mark II model 25...about $43 including shipping. Ordered from Global Test Supply.

I need to see how this chimney is pulling and getting the simple manometer will allow me to check the chimney and buy me some more time to research which magnahelic or digital unit I want. I'll probably just get a magnahelic later. I here analog gauges have their good points over digital gauges. I have no idea.
