Can someone recommend a good 6" barometric draft to use with my new Drolet HC? My understanding is that I need one that's made from black pipe or stainless (not galv), and is explosion proof. So far, these are what I've found.



I'm not sure what material the top one is made out of. I'm also not sure if either are explosion proof. The bottom one is at least black, but it comes as part of a Tee. I can use it in my application, but I'd be better off with one that wasn't already built into a Tee because of exactly where I want to install it. Push come to shove, I could make the bottom one work.

Also could use a recommendation for a suitable manometer to use for setting up the draft. Considering getting this (T168) but open to recommendations.


Thanks,
Mark

Where did you get the idea it has to be stainless and explosion proof?
I bet the members here are running that one you linked 100:1 vs anything else.

For manometer, Dwyer Mark ll model 25...$30-40 on ebay...no batteries needed.

FWIW, that manometer runs $45-$50 on ebay these days. There is a used one for $25, but is has bubbles in the tube which makes me not want to risk it. Amazon also sells it new for $53 delivered.

The air bubbles wouldn't scare me...you can work them out. Worst case scenario you pour out the oil and replace it, assuming that it has the red gauge oil with it still...that is stuff is pricey to buy by itself, so don't buy one that doesn't have it, unless its super cheap!
