drolet and osburn have exactly the same fireboxes. Enerzone has a 1/16" thicker top, otherwise also exactly the same. There are tiny niceties (tiny in my mind anyway) on the upscale models, that is all. The substance of the stoves are all the same. Chevy, Oldsmobile, Cadillac.
also, in models like the legend (3.3 feet) the osburn and enerzone have the curled down top at the front. The drolets are flat. I think I prefer the flat (even tho my top is not dead-flat (like maybe 1/32" bow in the middle)).I have a pretty straight eye and notice that stuff immediately. Many wouldn't. I'm sure that the curl helps to keep the top dead- flat during the welding process.
I'm fighting the wind today. Sigh. When the wind is straight out of the west, we have an intermittent down draft which makes starting the morning fire from coals a sometimes smokey affair. It happened this morning. Sheesh. Once the chimney is hot it can overpower almost any wind. Pita.
Ps, drolet's customer service through myfireplaceproducts.com is impeccable and more than generous. They have earned my loyalty on two stove purchases in the last 13 months. I imagine that applies in all of the SBI company?
Some minor things that are must-dos on the two drolet stoves I have experience with; tighten the allen set screws for the eccentric door hinge pins before the pins turn and pull the door out of alignment. Also, apply some anti-seize to the pins several times in the early stages (take the door off, antiseize the pins, put the door back on. Do this as soon as you feel the faintest friction while swinging the door. After several applications that becomes a very rare need - at least with the copper-coat I've been using). Dry graphite might be better, I haven't tried that.
Also, the door gasket splice at the bottom centre of the door can get damaged in the first few fires when the gasket tends to stick slightly to the stove body. It needs to be protected. I had that problem with the Columbia, which was rectified with a carefully applied small amount of hitemp silicone and a wee piece of tin foil. Fixed. Done. No more damage. No leak. I did the same to the legend stove before I even had a fire in it. Fixed, Done. This time with perhaps the tiniest whiff of a leak, as I see signs on the stove body that there's a wee bit of a draw there. Nothing of great concern tho, as it doesn't appear to breach the gasket whatsoever. I'll keep an eye on that.
myfireplaceproducts sent me a new gasket kit for the Columbia immediately when I called them about it. Not even a question. I didn't even have to ask. It was offered freely immediately. And now I have a spare.
I have a long story about exemplary customer service regarding my recent legend stove purchase too, but maybe later...
wind just howling out there. Damn.
PS, go as big as you can in the SBI lines. My assumption at this point that they are all good stuff and are backed by refreshing, prompt customer service in this age of waiting on hold for hours...
