    There's been recent discussion of vent cleaning, lint eaters, etc so I cleaned mine today for the first time. Stove's less than a year old with about 2 tons burnt through it. The lint eater worked fairly well, but did bind up a one point. After I sucked the stuff out with a leaf blower, I went inside and took the cap off the T to find just a tiny bit of ash left. Since I had the cap off, I decided to inspect into the venting just to see its state. That's when I noticed the screw tips poking into the vent. I assume this is NOT ok, right? What say you pellet gods?

    what type of venting is it? brandwise? most pellet vents dont require screws, but some do....ICC for instance. Generally, NO, you dont want the screw tips going through the inner section, which compromises the integrity of the inner liner.....

    On the venting proper the screws should not be long enough to pierce the inner lining, on the stove adapter they should go far enough to form a mechanical bond if the proper amount of sealant is on the pipe the adapter goes over and the screw is bedded into sealant a little protrusion shouldn't matter.

    The requirement in any case is for a gas tight mechanical seal.

    yeap......shouldnt protrude into the inner section...this allows for the possiblity of the exhause to get between the innor and outer layer, increasing the possiblity of leakage from weird places........."honey, do you smell smoke......?"
