Hi all. I have stove with @ 6' of double wall black pipe - straight up from collar to chimney (adapter). No screws in the flue collar at this time.
Heating season upon us, so as I clean the stove / chimney, check things over etc. I'm once again wondering about the flue section. I've done a quick search in the forum here and this is what I gather -
3 screws in flue collar are most often intended to address a single wall pipe connection - may not be the case for double wall flue connection, especially if the double wall pipe sits securely in the collar (i.e. takes a lot of force to get it apart), and flue is on top (not rear).
can someone please sanity check this for me?
I confess I've burned a couple seasons like this. The reason I haven't added the screws (beyond the fact I almost need a come-along to pull the pipe out of the flue without them) is that the exposed part of the collar is literally only about 3/4 " (the collar is actually deeper, but the Osburn 2200 has a "heat shield" on top where the trivet sits, which hides most of the collar). It took about 20 minutes to work / pull that pipe off the collar last time (e.g. when I had to move the stove to install a hearth pad). I actually thought I would have to crush the pipe to get it free.
I can't imagine how I would be able to get a drill on the collar, let alone at anywhere near 90 deg to the pipe, from anywhere except from the back of the stove. The need for screws everywhere else to keep the sections from coming apart is a bit more obvious to me, but what are the odds that any separation would happen right at the flue, i.e. the pipe lifting up and right out, especially with an extremely tight fit like this?
II don't recall seeing any pre-drilled holes in the collar before putting the pipe on. So I'm looking at going thru the steel collar which is probably @ 1/4".
Any thoughts / advice are appreciated....
