Will a smaller insulated chimney-pipe create draw problems?
Because my existing brick chimney does not meet the zero-zero clearance insurance specs for Canada, and hasn’t been used for a decade, I am planning on placing an insulated chimney-pipe in for my new wood stove. Unfortunately, a 6â€³ insulated pipe may not fit the existing chimney, and I have been advised to go with a 5.5â€³ pipe to ensure it fits.
Might there be any worry of draft (draw) problems with a 5.5â€³ pipe if my new stove collar (exhaust) is 7â€³, and my chimney height is 25feet with good outside clearance?
Grateful for advise,
