    Default Wood cookstove installation

    Sorry about the poor pic quality. I have this coming up in an inspection next week.

    I believe that a metal heat shield is needed under this stove, on a layer of 2" hollow core masonry blocks. Also the tiles don't appear to extend out 18" around all sides. Are allowances made for these stoves if they are built with double wall liners, maybe?

    Is single wall pipe allowed from the stove to the thimble in the ceiling? Is a pipe damper required or just advisable?

    That wall is likely lath and plaster, with a metal heat shield on 1" spacers. Is 12" the minimum distance to the back of the stove?

    Would have no way of knowing if pictured is a replica listed wood stove or an unlisted wood stove or one of significant vintage.

    Shiny screw-out dampers on the side of the firebox. It is likely a newer replica with an airtight firebox.

    Looks a lot like a Heartland. I have found a manual for the "Sweetheart with a towel rack".
    If the optional heat shield is installed on the back of the stove, the distance to the metal shield on the wall can be reduced to 2"!

    Floor Protection
    When installing this cookstove on a combustible floor, a
    noncombustible floor protector is required under the stove.
    The floor pad is to protect the floor from hot embers that may
    fall from the loading door. The floor pad must be continuous
    noncombustible surface. Floor tiles with grouting between them
    or sheet metal pads are acceptable. The pad must

    extend 450 mm (18”) beyond any side with a loading door
    and 200 mm (8”) beyond the other sides and rear. (See
    page 10 “Oval Rough-in Dimension Diagram” or page 11
    SweetHeart Rough-in Dimension Diagram”.) Floor pads
    may be fabricated from non-combustible materials. (see page
    29 “Formula for Equivalent Hearth Extension”)


    To prevent overfiring:
    1. If the air intake has little effect on dampering the fire, excessive chimney draft is the
    probable cause (especially on chimneys in excess of 20’). Normal chimney draft
    is approximately 0.05”. Install a smoke pipe damper in the pipe approximately 5’
    from the floor. NOTE: Open damper before opening door to prevent smoking.
    2. Install a magnetic thermometer on the top of your stove near the flue collar or a
    probe-type thermometer in the smoke pipe.
    To prevent creosote buildup in the pipes, the stove should be run between 800F
    and 900F for 30-45 minutes each burning day.
    3. Except for the initial period after lighting (5-10 minutes), do not operate your stove
    with the door open.
    4. Ensure the ash pan door is tightly closed during operation. An open ash pan door
    will allow excess draft through the firebox, causing overfiring. When emptying
    ashes, clean thoroughly behind the ash pan to allow complete closure.
    5. Clean your chimney regularly to remove creosote buildup. A chimney fire is a
    fire hazard and will overfire your stove.
