The instructions say the kit comes with a replacement gasket.

They also say to use tape or rtv silicone to temporarily hold the gasket in place if required.

edit: wise to use high temperature stuff if u end up using any silicone, the exhaust can be 300 to 400F+.

If the furnace is 15+ years old, take a good look at the heat exchanger before bothering to replace the inducer. Visible by pulling the blower and looking up or if you don't have an a/c coil right above, can open up the plenum and check from the top.

Look up your furnace model to see if it's prone to cracking and where -> if i remember correctly some carrier 80% models had a lot of problems.

You can use some red or black RTV silicone to stick the gasket on to the housing. The black RTV is sold in auto repair shops for auto use and red RTV is HVAC type.

It is pretty straightforward. Unhook the wires and there may be 3-4 screws holding it in place. Remove them and the old unit and see where the original gasket sits.

Then you may want to stick the new gasket on with a thin layer of RTV silicone. Put the new fan in. If the screws are rusted and eaten away then use new ones. You can buy them at HDepot.

Shouldn’t really be needed.
As stated above verify your heat exchanger is sound before before investing in the unit. You didn’t give age or model. Some Bryant furnaces are affected by a class action lawsuit for defective heat exchangers.

I never use silicone on that gasket... just hang it on a couple of the screws as you put it in place.

Good idea to check the heat exchanger before investing $200 +- into that unit.

Check around for a better price...

That is a mid efficiency furnace and as far as I know only the high efficiency units had heat exchanger problems and the class action lawsuit because of the secondary.

Some of those units have cracks around the dimples but they would be very difficult for a DIYer to see if you don't know exactly where to look.

Yeah that sounds pretty expensive the price of that unit.
