Wood stove gasket replacement

This fall, had my stove cleaned and checked, and he also changed the door gasket.   Apparently,  it is not right .   Sides are turning black, and allowing alot of air to enter stove.   My burn time is about 2-1/2 hrs.    This stove is our only source of heat.    The manual says to use a 7/8" gasket, and the only one I can find around here is 1 inch.   Tomorrow it is supposed to be a warm day (for central NY),  and I am going to clean the stove pipe and stove, and would like to change the gasket - which I am not a pro at.   My question is - can I use a 1 inch in place of the 7/8 inch gasket?   And if so,  do I stretch it out a little.   Please help - thank you.

Well...there are those with more diverse experience to answer this question for you, but from my own trials and tribulations, as long as your door handle the closes the gasket against the metal frame can be adjusted in or out to accommodate a thicker or thinner gasket, then you may be okay to use the 1" gasket.    But if you are not sure and your old gasket still has a bit of life left in it, I would carefully pull the old gasket off so that it is retained in one piece (if possible), gently remove any of the old gasket cement from the rope and from the channel on the door, and then brush away any loose debris from both gasket and channel.  Now add new gasket cement to the door channel, re-seat the rope gasket, and close the door so that the door frame holds the gasket against the cement for several hours.  One good burn in the stove should cure the cement and you hopefully will be good for the rest of the winter.  Good luck!

Thank you John.    I was checking out the old gasket, and it is coming off, apparently not enough cemet to hold it together.   I am going to go and get the 1 inch and try it.   The door handle is adjustable, so hopefully it will be fine.   Going from   a 5 - 6 hour burn to  a  2-1/2 hour burn is a little tough.   Again, thank you
