Top down feverA new (old) fire building technique.What has kept many of us engaged, if not engrossed, in the field of woodburning for our entire careers is its constant evolution and frequent surprises. For twenty years and more, we've been caught up in a wood heat vortex that has swept us along through the era of funky, ugly black box stoves, the early rash of house fires, the huge regulatory flaps – first over safety, then over smoke emissions – the appearance of wood pellet-fired heaters, then colorful, beautiful stoves and fireplaces with clear glass, no smoke and seventy per cent plus efficiency. We figured we'd about seen everything. Now, of all things, fire building itself has been reinvented.Since the early 1990s, it has become de rigueur among many in the business, and by extension, their customers, to build their fires top down. The conventional approach, as you know, is to crumple some newspaper, put some fine kindling on that and some heavier kindling on top, light the paper and watch as the whole affair collapses into a smoldering mess. Or, as sometimes happens, it catches enough that you can begin to add bigger pieces until you have a respectable fire.
The top down technique is the
counter-intuitive opposite: put down three or four full sized pieces of
firewood, then a layer of coarse kindling, then some fine kindling on
that and top off the pile with a couple of sheets of crumpled paper. The
paper is lit and, believe it or not, the fire builds progressively,
gaining intensity, down through the layers to the biggest
logs on the bottom. It's a wonderful thing to watch.I first heard about the technique back in 1992 in the newsletter of the Masonry Heater Association (whose headline I stole for this article) and first tried it during a camping trip deep in the wilderness of Algonquin Park. It worked perfectly, but I was still skeptical until I tried it a few times in various stoves and fireplaces. It has worked perfectly ever since and I wouldn't consider using the conventional method, except in a cook stove. For most of us who heat with steel or cast iron stoves or fireplaces, particularly those that are approved by the U.S. Environmental Protection Agency (EPA), a true top down fire is impossible because the fireboxes are limited in height. That's okay, just use a modified approach that might referred to as front to back: put two or three full size split pieces towards the back of the firebox, then a few pieces of heavy kindling, then lean a dozen thumb size pieces of kindling against them and add a few crumpled sheets of newspaper at the front of the firebox. Light off the paper and watch the fire build steadily towards the back of the firebox.
I have spoken to a lot of people about
top down fires, including two on-air interviews with Morningside, the
popular national morning show on the radio network of the Canadian
Broadcasting Corporation. I have found there are three primary responses
to the concept. The first is absolute amazement at how well it works and
a solemn commitment to use it from then on; the second is the claim that
although it was tried, it didn't work; and the third is that the top
down fire is old news, that my (uncle, grandfather, whatever) used to do
it that way. Which only proves that wood burners are an independent lot. JG |
