3 am three days ago I decided I really needed to more thoroughly clean the iconal screen. It dislodged slightly, and mindful of others' experience with the screen becoming difficult to get out, I lowered it into the fire box, removed it from the stove and thoroughly cleaned it. I found it had some stubborn crusty material on the screen itself as opposed to only having the holes obstructed, so took a fine silk pin and pried this encrustation off, as I suspected leaving it would result in quicker subsequent build up. I cleaned the screen thoroughly with a fine natural bristle rounded sash paint brush, then, at 5;30 Am realized I didn't have a clue how Woodstock suggested replacing the screen. There were no instructions in the PH manual, so I proceeded to clean the ashes out of the stove while I waited for Woodstock to open...house getting chilly. Spoke to Penny at 9AM, who promptly e-mailed me clear, well-illustrated instructions for reinstallation. I asked her incidentally whether she had ever tried to replace one of these screens. She had not. I indicated I felt the iconal screen was an issue with which they needed to deal, and she let me know they realized that.
After a dozen or so attempts at installing the screen as indiciated, and having had no success whatsoever in getting the screen to budge when trying to slide one piece over the other, I installed them subsequently instead of simultaneously. First screen snapped into place, second just sort of sat there. I couldn't get it into place. Called Woodstock, got Jamie, asked is I could burn with the screen as is...told fine as long as it wasn't moving.
Proceeded to build the fire in my stove...16 inch wood because it was already cut for my Fireview, maple and ironwood, box about 60% full, a small strip of birchbark a few match stick thick twigs and a 1/2 inch short twig/branch. Lit the birchbark at 10 AM, the fire was blazing within five minutes. Took under 15 minutes with damper 2/3 closed to achieve temperature to permit engaging the cat. Got a 10 hour burn. Reloaded at 8 PM, stove 80% full of 16 inch lengths, so about 65% full by volume (my biggest fire yet), and fire had ignited from coals before I closed the door. I got a 16 hour burn...my first 16 hour burn. Called Woodstock to report this (they deserve good feedback as well as queries), got Penny, who had gone to the shop and tried installing the screen subsequent to our conversation and had a further suggestion from the engineers there, which I shall try next time I clean and re-install the screen.
Call Woodstock with any questions about the operation of their stoves...they are not only very helpful, but need the feedback to address and improve any nagging details. I have been informed more than once by them that any improvements they make will be retrofitted to all our stoves.
Was told that they are working on a way to prevent the screen from dislodging while cleaning. The screen has the tiny holes to keep more fly ash out of the cat because the SS cat has smaller honeycombs than the ceramic and is more prone to fly ash accumulation. I have a suspicion that my substantial draft probably pulls more fly ash up into the screen/cat. My few, never to be repeated, "whooshes" with newspaper probably didn't help. I did pull the cat while cleaning the screen, although it looked clear. The distal side was completely --every hole- blocked by white ash. I gently tapped the cat on a piece of newspaper placed o the hearth, and all the ash fell out. Brushed both sides with my paint brush, but nothing came out with that. All was clear. Reinstalled the cat, brushed the interior of the upper part of the stove, vacuumed out the tiny pile of white ash. I'll check the cat again one morning in a few weeks, but suspect in my setting it may require cleaning every month or so of 24/7 burning. Not a very burdensome task in this stove, do-able with no trouble when the stovetop is a 120 degrees as long as you brush or tap and don't vacuum the cat.
By the way, after my 16 hour burn, I had light gray ash and about a gallon in volume of coals,stovetop temp of 180 degrees. Loaded stove, fire lit immediately. Have not loaded the stove as full subsequently, because at the moment 12 hour fires are more convenient for me. I have consistently gotten 12 hour fires, am managing to get cat fires, have gray ash and a few coals left at the end of the burn. I've burned a little over a cord of good dry ironwood and maple so far this winter.
I'm very happy with this stove. My house is comfortable. The stove is a handsome addition to the living room.
