Rick,
About 2 weeks ago, you did the final mechanical inspection at 11530 SW Tigard Dr. The two
corrections you came up with were.
A) Vent pipe should be 2" PVC instead of 1W
B) Vent pipe should be insulated, per manufacturers' instructions.
Hopefully, both of these were simply an oversight on your part, or a misunderstanding of the
manufacturers' instructions. I have enclosed the pertinent pages from the installation manual for your
reference. By way of reminder, this was a downflow 90% Carrier gas furnace in the garage, with the
exhaust & intake pipes running to the roof Each pipe is 9 feet long with 3 90° elbows. As far as i can
see, this is a legal installation. Am I wrong?
Please get back to me ASAP, as my customer is eager to be done with the project.
Thanks,
Jason Young
