    Three weeks of operation and 3 upper door removals and adjustments = smoke free operation
    Thanks to all those who have contributed on this site, thought I would compile this in one topic here is what I went through for smoke free operations
    You will find repetitive steps and maybe something new

    Remove front plate on top door and insulation - silicone door plate bolt holes to seal tight

    Crank hinges in one turn

    lay a bead silicon in the groove of the existing gasket

    Install 1/4 inch stove gasket on top of silicone in groove - seal butt ends with a little silicone- I tried just a silicone layer first but hinge area still leaked

    Let dry for a few hours so not tacky

    Examine door frame weld in hinge lug area - I had smoke escaping some weld areas and a space left in this area between the metal and sealed with silicone

    reinstall door and close partially tight until dry 3-4hrs

    This should seal the loading door and gasket more thoroughly - you may need to crank the hinge bolts one more time after this retro but try this first

    Pull Front fan panel off and remove gasket if loose reapply with silicone layer, then gasket then another layer of silicone on top of gasket - mine was leaking from top right corner where a black streak was visible and gasket was loose.

    make sure your stove pipe is sealed in all joint areas with refractory - Rutland makes both high temp silicone 500 and 600 degree along with blk refractory cement in a tube.

    Don't open the loading door until temps start to drop to 170's range to refill

    Hopefully there will be an easier fix with a new gasket material soon. Silicone impregnated gasket rope? Hopefully my recipe will last awhile.

    My wife is happy and I am happy :) :coolsmile: ;-)

    My Wood Gun had silicone rubber door gskets. When I repaired them I would place waxed paper between the silicone rubber and the gasket seat and lightly close the door until it cured.

    Thanks TF this was just the info I was looking for. I have done everything else but silicone the door gasket and I still have smoke smell. I guess I will be looking for high temp silicone this weekend.

    I guess I will take my chances and seal it on the boiler while its running. worse comes to worse I will have to so it again when the boiler is shut down.
