Rated 3 out of 5 by from Vent size Where is the vent size on the spec’s, are we supposed to guess, and when I ordered the venting for the 45-H, you send me 3” vent kit ??!!. How about you add a line or two in regards to what vent kit, the part number for: horizontal or vertical, that will fit each unit. So we don’t have to guess.

Why does this require 12 amps of power to run a fan and a circuit board? Is it actually 1.2?
