<div dir="ltr">in a recent project for other pyrophilic clients, (and despite all
my hand wringing to them) I spec'd a wood stove by Napoleon: <a href="http://www.napoleonfireplaces.com/products/nz26-zero-clearance-and-masonry-fireplace/" target="_blank">http://www.napoleonfireplaces.com/products/nz26-zero-clearance-and-masonry-fireplace/</a>
<div> </div>
<div>even with that gratuitous feature (and a conventional clothes drier) the
house came in below 0.6 ACH@50 PA. One nice feature is that the stove has
provision to route air heated within its jacket to remote locations, so the
occupants don't collapse from heat prostration while it's in use. In the subject
case, hot air was ducted to a point adjacent to the heat pump return (direct
connect is prohibited by the mnfr)</div>
<div> </div>
<div>one thing to bear in mind is that the length of the flue, even with a roof
top damper, represents an ambient or near ambient condition. applying insulation
directly against the flue is prohibited, so an insulated chase was provided
instead.</div>
