    DO NOT BURN WET COAL

    WARNINGS

    INTRODUCTIONThis all new design by Harman features the Verti-Flow Stoker System.

    This unique system provides a very wide range of heat output. TheVerti-Flow Stoker can operate from 5000 to over 85,000 btu's automatically.

    This unit has a 100 pound coal capacity and can provide 85,000 btu'sfor 17 hours or stretch out to over 100 hours when less heat is required.

    A thermostat is used to regulate the heat output of the stove. When noheat is needed, the stoker stops and only runs to maintain the fire. If heat isneeded, the thermostat can turn on the stoker at any time. After the thermostatis satisfied, the stoker will turn off for twelve minutes and then run for fourminutes.

    The four minutes "on" and twelve minutes "off" is a setting that willperform well under most conditions. This "on" and "off" time can be changedto provide more or less heat during the maintenance cycle.

    This unit must be connected to a chimney capable of providing a .04minimum draft reading. WARNING!! If the chimney has no draft, coal gasesmay escape from the unit and stovepipe. These gases are toxic and can befatal. It is recommended that a gas detector be installed to warn of thiscondition. Check with your local stove dealer for purchasing a gas detector.

    TESTING INFORMATION This unit has been tested and approved by OMNI-TEST Labo-

    ratories in accordance to the listed codes.

    DO NOT BURN WET COAL

    READ THIS

    Always empty hopper when not burning for more than a

    week. When left standing for long periods with wet coal,

    the pusher block will rust and corrode, causing it to

    seize. If the stoker is then turned "on", damage to the

    pusher assembly and feed motor will result. This will be

    considered neglect and will void the warranty on those

    parts. Always check to see if moving parts are free

    before using if the unit has not been burned for a period

    of time. This can best be determined by shaking the

    adjuster rod.

    Freshly delivered coal is watered downto eliminate dust when loading and unloading.Wet rice coal does not flow as well as damp ordry coal. We do not recommend burning wetcoal, however, we realize if it's the only coal youhave it is better to burn it than freeze. If youmust burn wet coal, the feed rate must be in-creased in order to get the same size fire. As thewet coal in the hopper dries out, the feed ratemust be decreased. If you dont, the feeder willover-fire the stove and waste coal. Doing thisonce or twice a year will not damage your stoveas long as it is hot and burning. The damage iscaused when the hopper has wet coal in it whenth e s to ve is co ld . This will cause rust and corro-sion and it is totally the operators fault.

    Usually after the coal dries for threeor four days, depending on conditions, it willflow very well and feed properly. Feed ratewill be the same as dry coal.

    Damp coal also should not be left inthe hopper of a cold stove.

    Be sure the grate holderis centered and back asfar as possible.

    IMPORTANTInstall firebricksas Shown

    The grate holder must be installed through the top dooropening after the feeder has been installed.

    Locate the flange at the rear of the grate holder into the sloton the feeder as shown below. Bolt the front end down with the1/4 x 20 Allen bolt and nut provided. The rear end will be lockedin place by the flange. Before tightening the bolt be sure the grateholder is back as far as possible and centered side to side on thefeeder opening.

    Install grate inserts as shown at left. Divide the spacesbetween the inserts equally and be sure they are not tight. Thespaces are needed for expansion.

    HopperInstall hopper support on top rear of stoker.Note that bolt holes in hopper support are slotted for adjust-

    ment. Insert small end of hopper into the hopper slot on the feederas shown. Push top of hopper under the hopper support, causingthe slot on the bottom side of the support to hook onto the hopper.The hopper support will spring up slightly for the hopper to gounder. If you have difficulty getting the hopper under, adjustmentmay be necessary. Use slotted holes shown at left. Now the feedmotor cover can be installed.Grate

    The grate is composed of four pieces:the grate holder, (2)grate inserts, and grate angle. The grate angle is bolted to thegrate holder with (2) 3/8 X 1 1/4 bolts. Before installing the grateholder, 3/8" round gasket must be checked in the groove on thebotton side of the grate holder, as shown in fig. 7. Check to be surethe gasket has not been damaged.
