warnings
never sleep in the same room with any coal burning stove.
Always empty the 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 typically watered down to minimize dust when loading and unloading. Wet rice coal does not flow as
well as damp or dry coal, and may bind or bridge in the hopper. We do not recommend loading your hopper with wet coal. If
you must burn wet coal, the feed rate will likely need increased, in order to get the same size fire. As the wet coal in the hopper
dries out, the feed rate will need decreased to avoid over-feeding. Using wet coal, in an emergency, will likely not damage
your stove as long as it is hot and burning at the time. The damage is caused when the hopper has wet coal in it when the
stove is cold. This will cause rust and corrosion which is considered neglect and will not be covered by the product warranty.
This unit must be connected to a chimney capable of providing a -.04 minimum draft. warnIng: If the chimney has no draft,
coal gases may escape from the unit and stove pipe. These gases are toxic and can be fatal. It is recommended that a CO
detector be installed to warn of this condition.
appliance Placement: The VF3000 must be installed on a non-combustible floor. The non-combustible floor must also extend
a minimum of 18” in front of the firebox door, and 8” to the sides. Maintain a minimum of 18” of clearance to combustible
walls, 24” to the ceiling and keep combustible materials a minimum of 36” away from in front of the appliance.
This boiler may be connected to an existing boiler heating system. Inter-connection may be done in a series or parallel
configuration. Consult with your licensed plumber or HVAC professional to determine the most effective installation for your
heating needs.
