Stove in new 'tight' home. Experiences? Advice?

[firestickasteroid]

I'm looking at the Blaze King Sentry S14 installed in a home being constructed in Canada. New building code means the home will be pretty tight. We're reducing the depressurization surfaces by having bathrooms managed through the air exchange, and we're considering a heat pump dryer. That leaves a 3-400 CFM range fan.

For reference, our chimney is looking to be at least 16' from flue collar to where the cap attaches, and a complete straight run without any elbows. There will be roughly 10' within the home itself.

I'm trying to make a decision on whether to get:
- A passive direct air intake to the stove
- A passive vent
- A user operated 'makeup' intake like an in-line duct fan certified for cold operation (and possibly bringing in 10F air)

I've been through many posts on here about intakes. I've read all the different information I can find. I've read Sweeps Library posts, I've read Annex D in CSA365 (which states a direct intake may not prevent reversal/depressurization effects). . . . .Nothing is conclusive enough to point and say DO THIS.

I'm interested in knowing what the community would do/has done with a new home/tight home/passive house.

Thank you!

Outside air kit, plumbs outside air right into the stoves intake. Make sure it terminates below the stoves intake so draft reversal is not possible.

I'd do an OAK. But I would properly connect it to the intake. Otherwise you're going to have cold feet.
Download the manual from the bk site to see requirements (I assume the sentry does have an OAK connector to go with it).

Not sure if you're inna windy area. Best to have the OAK not on the downwind side of the home as there pressure can be lower.
Be sure snow can't clog it up and that it ends at least level or below the intake of the stove.

That's one of my problems, @stoveliker. We only have one side it can go on, and thankfully winter winds blow onto that side of the home 35-40% of the time (from my assessment). It's the rest we can't account for.

Am I also over-thinking this?

It's good to think about it
It's not without risk. But if you follow the manual and regs about it, it's likely going to be ok imo.

The main thing is that you want to avoid reverse draft due the the oak piping going up (and drafting like a chimney) or due to low pressure outside.

There is also a risk of having the stove belch smoke and gases in a tight home with no oak...

You can also add an hrv or erv to your home to avoid an oak and avoid low pressure in the home (when an exhaust fan kicks on).

We will, thankfully, have a well-balanced HRV. I know it can't 100% prevent any depressurization but will obviously help

My oak is on the windy side of the house and no issue with the BK
