Installing a Wood Burning Stove: Part III

With the deck iron in place, it is time to work out the details of setting the stove in place and fitting the flue pipes.  The enclosure from the original kerosene heater is lined in asbestos and requires some modification to make it more effective. Basically, the floor of the enclosure needed to be raised and leveled, and the space below converted to a short term fuel storage spot.  A simple carpentry effort made short work of that.

I've re-used the asbestos sheets that lined the space.  Asbestos is very dangerous as dust, but as long as it is stable, it presents no health hazard.  Reusing it involved making a few cuts (dust), but also keeps the material out of the landfill,  so the tradeoff seems reasonable to me.

The alternative to asbestos is to create a heat shield which is comprised of sheet metal (typically copper or stainless steel) offset from combustible surfaces by an air barrier (1 inch is the standard recommendation).  In designing mine, I educed that air space to 1/…

Installing a Wood Burning Stove: Part II

Cutting a hole in a perfectly good house top is daunting business, but it has to be done.  Fitting a deck iron (which is bronze) is less daunting, but a lot of work.  The deck iron wants to be level and the house top is not, so it is necessary to make a donut that supports the deck iron and levels it.

Taking the angle is simple enough.  Cutting the angle in a 9 inch square block of hardwood 3 inches thick requires multiple angled cuts on the table saw, and finishing with a hand saw.  The only hardwood I had that was thick enough was a slab of walnut.  Walnut is suboptimal for nautical uses (it is not particularly rot resistant), but painted well and properly maintained, it will do the job nicely.

The interior of the donut need not be cut precisely -- it just need to accept the bronze deck iron without leaving excessive space around the walls of the casting.  I wasted the interior of the donut with a drill bit, and then chucked a drum sander in the drill press and ground out the sloped…

Installing a Wood Burning Stove: Part I

Many of my 88 days on the Inside Passage found me layered up in wool and foulies, but with one exception, being cold just wasn't a problem. What was a problem was keeping the cabin dry. Humans respire about a quart of water while sleeping, and Ripple has rudimentary rain protection in the cockpit, so inevitably a good deal of water comes into the cockpit via wet gear and crew.

Testimony regarding the virtues of wood burning stoves in boats is widespread, and the appeal of a cozy fire on a blustery day is self evident. Finding a suitable unit for Ripple rose to the top of my upgrade program. It is a complicated proposition.

Having  made the decision to go with a wood-burner, one still has a potentially vast array of options. My own were severely constrained by space availability. The Force 10 kerosene burner was designed into the boat, leaving the choice of reworking cabinet work or finding a stove to fit within the 12" by 13" by 16" space.

The stove I most coveted …
