Question: We were given an old Fisher Wood stove for my husbands woodworking shop. Do you know where we can buy a Fisher adaptor in Canada and 8 inch pipe (double lined to meet code)? Also, are there recommendations for using woodstoves in woodworking shops? Answer: Many woodworking shops prohibit the use of any heaters with open flames....this is considered an open flame. Not sure about the codes in your area and the use of your shop, so I cannot make a definite determination. There is no such thing as a Fisher adapter. The stoves used 8" pipe, the crimped end of which should fit down inside the flue collar of the stove. Some of the flue collars were made into a strange size and may require extra crimping or a homemade adapter of some sort. You can buy double wall interior or exterior class A chimney at virtually any fireplace or stove shop.
