I'm a long time lurker here. Great forum. I am nearly finished with my install of my Quadrafire 7100 in my basement remodel project. I did my first burn last night. Great unit that puts out a TON of heat. However, the remote heat zone blows only moderately warm air out of the vent. The pipe rune from the basement to the first floor is right at 10 feet. The heat zone kit has a pipe that extends 16 inches down into the unit so that it is drawing air from farther down in the back of the unit. For longer runs, greater than 10 feet, the manual suggests trimming the length of the pipe to draw in the air from higher in the unit. Here is the question, finally. Why wouldn't you want to draw the air off the top of the unit? For my run of 10 feet, should I trim the pipe? I need to make a decision on this before I seal the unit up behind rock wall. Anyone with 7100 experience have any thoughts? Great forum. Thanks in advance for the advice!
