Good morning all!

The warm weather has arrived in Massachusetts, and i am being told by the place i bought our Heatilator Pellet Stove from that i should disconnect it from outside air so that it doesnt get rusty on the inside from the humidity.

Seeing if anyone here has a best-practice for doing this.

Do i cover the exhaust pipe from the outside somehow?

Do i block off/disconnect the air intake vent?

Thanks in advance!

Not just for humidity, but good way to keep critters out.

I ball up some newspaper and stuff it in the exhaust, slide a ziploc bag over it, then snug up with a wide rubber band.

The OAK, I disconnect from the stove and stuff newspaper in.

Then I put a stickey on the control panel to remind myself of what I need to take care of prior to starting it back up

I put a plastic freezer bag over the top of my outside exhaust with a couple zipties..
i cover my OAK vent with duct tape and put 2 cans of damprid in the stove.
1 in the firebox, 1 in the ashpan. the pix below shows approx 4" of water collected over the spring/ summer..
this was before i started sealing off the exhaust top with the freezer bag.
i also spray the inside firebox walls with pam cooking spray.. [un-flavored of course]...
