Kevin,
If I were you, I'd throw a small piece in the microwave and check it first. On
chimneys, I think it's actually better to leave a small gap of maybe 1/32" to
1/16" all around the anode radiator, running the chimney all the way to the
top. The reason why is this allows the air to go over the outside surface of
the radiator also giving it more surface area in the air flow. Every little bit
helps cool it down. I've seen some who clamp tubing tight around them and in my
opinion, that does more harm than good. That's my opinion though as I never was
good in thermodynamics (C's and D's from too much partying) hi hi!
Best,
Will
