Today I tore down my Castile stove its had an exhuast leak since I bought it in 2006. I removerd the combustion blower and housing and will reseal all the pipe leaving the stove. I have to order the blower housing gasket it came apart. This time I siliconed the the stove pipe adaptor inside the double wall, cleaned all parts of the stove. I found a leak at the exhaust connection of the blower housing and the fitting for the stove adaptor. Used 500 degree clear rtv silicon I hope this will cure my leaks. I will clean the stove pipe when stove is back together. Looking to use a leaf blower as my last step.
