Hi! I am new to this forum... I have been operating my 1977 Vigilant model 1400 coal/multifuel stove for about 20 years... I have always burned wood.No real issues until now. My damper on the side of the stove seems to fall back to the open position.. it then in turn causes my burn temp to rise to high.. not sure if the damper retainer is wore out or what.... I have to replace the front door handle assembly as it wearing out so I'm thinking the damper retainer might be wore out too. This stove has been very good to me ... anyone have any ideas??
