Maybe a bad choice of words about receiving bad advice from Home Depot. It was just his opinion and he was up front with me that I need to follow local code. He was actually quite knowledgeable. And it is ultimately the customers responsiblity to make sure to follow code. I appreciated his advice. I respectfully take exception that Home Depot should not be telling people how to install. They are after all a DIY store. That was the whole reason for buying the Englander in the first place. I was short on money and did not want to pay a professional installer. And based on their excellent web site and video, it seems like Englander caters to customer like me.
Correct. The DIYer is their target market. Tech support is only as far as this forum away Mike Holten is a member here and works for them although I can't recall seeing him posting in the past few weeks. As far as the wall thimble. It's my understanding that the wall thimble is simply to protect the pipe from combustible materials, such as the wall. What if I went through the concrete?
No thimble necessary. Cut a hole just big enough to slip the pipe thru and silicone around it to seal it. Is there a concrete thimble?
Nope. I may be wrong but since I made the window inoperable and used a non-combustible material, I don't think a thimble is necessary.
I tend to agree - although you didn't make it insulative - the metal will draw heat from the pipe and may transfer it to anything combustible it is in contact with. Thimbles have an air pocket around them which provides insulation as well as non-combustibility provided by the metal thimble. If it's the typical basement window, it's in a metal frame embedded in concrete which makes this a non-issue for you. I'll let all know what the inspector says. Does anyone else have any insight to the window part of the installation? Thanks all for your help.
