    Default Pellet Stove

    This pellet stove uses a b-vent for the flue. Is this ok? The instruction manual wasn't around, and I can't find what I'm looking for on the net.

    Thanks,
    Joe

    No nothing is "okay" about what you have photographed.

    It looks like you have to use a pipe made for the application. Here is a link to an example.

    Cool Re: Pellet Stove

    You must use pellet vent, which is actually type 'L' vent, which was orginally designed for oil heaters. Standard L vent requires you seal every joint with red high temp. RTV silicone, whereas some of the newer types of "pellet vent" claim you do not. Pellet vent looks identical to B-vent except the inner liner is stainless steel. The sticker or embossed markings on the outer casing of the vent must identify the type of vent, mfr., size and clearance to combustibles. An arrow must indicate which way is up/out.

    B-vent is listed to UL 441 while L vent is "UL 641.
    The appliance must be installed per the mfrs. listed instructions and any state or local codes that apply.

    HTH

    Keep the fire in the fireplace.

    The Dura-Vent claims to have silicone sealant embedded in the joint.

    I didn't realize it had to be red RTV sealant - I used black RTV on my own install. Crap - now I'm gonna have to redo it.

    Cool RTV info

    Check the manual on the stove for a temp. rating. Most black and clear RTVs are rated 550*F intermittent/ 500*F continuous while most reds are 650/600*F. However, you can get a gray/ silver RTV with the same higher temp. ratings from your auto supply so you cannot assume just by color.

    One other note: acetoxcy cure RTVs such as your 500*F and lower temp. ratings are excellent adhesives for metal to metal with thin joints but are very poor at gap filling. They can cause corrosion, esp. on galvanized steel, which it is used on all the time.

    Neutral cure RTVs are better suited for gap filling but have poor adhesive properties.
    HTH,

    Just re-read both and I'm good.

    The pellet stove instructions say follow the vent pipe manufacturer instructions. The vent pipe manufacturer instructions (DuraVent PVP) say to use 500 RTV sealant at the appliance adapter and optionally at pipe joints. I'm sure if they had specified 600 RTV I would have noticed and looked for it specifically.

    Going along with H.G.'s comment about nothing right. I believe that part of Michigan gets a fair amount of snow! But then I guess the smoke in the room will remind you to shovel it away after you have started the fire!

    The beatings will continue until morale has improved. mgt.

    Oh, I just looked at the pic again, and everything is ok cause you can shovel the snow from the open window!

    I like the water stains and rust on the vent inside the house. Notice the white stains on the floor.

    That would be difficult since the higher grade slope is beyond the termination (note errosion)!

    Not to mention the flamable pallet and unsecured 1-1/2" thick 18" square patio pavers which don't overlap that pallet face atop carpet won't be supporting the overhanging stove (both corners) when said pellet stove tips over, while the bedroom occupant is "shoveling", those curtains catch fire, and the EERO itself, as well as the path to same IS blocked/obstructed by the positioning of the device.

    How about that flamable carpet? Check out that ash spillage.

    Yep, note zinc burn; also soot on inside wall.

    Scores of other "issues" on this death-trap/fire hazard/poisoning/unconventional installation.

    Easiest issue is denial of fire/hazard/property insurance coverage.

    You can view NFPA 211 on-line at no charge, just register with NFPA.org. You can defer to a specialist if you'd prefer - but there is frankly NOTHING correct about what has been pictured, more importantly it IS dangerously wrong (hazard to persons and property).

    By the way, that looks like a PelPro FPP2BD. The instruction manual can be found here: Install Guide: Freestanding & Insert Stoves
