I am replacing my Combustion Blower on my pellet stove, and am looking for a sealing compound that I can brush on to seal the entire exhaust pipe and the heat transfer pipe. I noticed that when I disassembled the unit, the sealing compound was a rubber like compound. Do you know if this is the correct sealant that I need?

Answer:The material being used is likely a high temperature RTV rubberized sealant. That is the same type of sealant that you are currently viewing and is the correct product to be used for sealing direct vent gas and pellet vent piping.

Will this Sealant fill a Narrow Crack Between the Top and Side of my Wood Stove; and will it Expand and Contract when the Wood Stove heats up and cools down?
Do you know if this Sealant will maintain its flexibility and not fall out of this narrow crack that is about 1/16-1/8 inch or less wide where the Weld is that holds the Metal Top of my Stove to the Right Metal Side of my Stove?
Do you have any other products (or suggestions) that I could use to seal this Narrow Crack which is about 8 inches long in my Wood Stove?

In order to repair the crack in your stove, I would recommend the following item:
Rutland Pre-Mixed Black Furnace Cement - 10.3 Ounce Cartridge
This type of furnace cement is specifically made to bridge the size of gap you have and stand up to the temperatures the stove is capable of, without losing it's bond or shrinking.
