Checking overfire draft

Looking to see what you guys use to block the large openings on older boilers when checking overfire draft. I've been using a rag up till now but there has to be a more refined way. I am using an UEI 125 tester.



Thanks for the tips

    Next time you install a bathtub chamber

    save the disc from where you cut out the hole for the burner head. Make a hole in the middle for your probe, and you're done!
