I have a customer that has a Hardie outdoor wood stove that's having trouble with the GFCI tripping. The stove is approximately 13 years old and once you remove the back cover, there's a GFCI receptacle that the pump and the fan is plugged into. Sometimes if the fan appears to not be working correctly, there's some moisture in there and the GFCI trips. Does this stove have to have the GFCI receptacle or could the pump and fan wire be direct wired into the junction box inside the stove where the current GFCI receptacle is and eliminate the GFCI receptacle?
