2, 200sqf boxes for the price of one ..HD miss order ...my gain! , I plan to use it on my HRV line anyway and then the rest of it on the boiler......but with the 2fer 1 deal> I got more that enough !

Don't use it directly to the steel, auto ignition temp is 400 degrees and I bet all the boilers you hear of burning went above that.

Do you have good access to your sill plate and rim boArd in yours basement? That is a classic spot for heat loss and can gain you good air sealing along with r value. That is where I would use it.

The msds says not over 250 ...all but the door of the boiler is a water jacket and I would not be covering the face of the boiler .and I will be coating the foam with a good coating. If the outside of my boiler gets to 400,degs I will be having a lot of other issues! IMO..

You're right in that if it goes to 400℉ you've got bigger issues. :)
But I have seen boilers run low in water and melt fiberglass but not get any spread the fire elsewhere.
With foam you would have the potential for a much bigger fire when it lights up.
Not saying you shouldn't use it, just a thought.

Shouldn't really need to should you?

That's funny Eldon, so have I in fact it wasn't long ago when HeatMaster had me out changing turbulators that were a new try but turned out to be to light duty, well in pulling apart the top of the unit I was finding burned fiberglass in the area above the heat exchanger tubes, in HeatMasters defense it was probably from folks running the unit with the bypass open for to long but I would have thought a heat shield of some sort would have been in there. I think I still have the pics that I sent Jake Friesen, would you like me to post them so you can see them?
