Harman Stove Company DVC-500 manual Carbon Monoxide CO Awareness, Wet Coal, Always Empty Hopper

WARNINGS4

Carbon Monoxide (CO) Awareness

Carbon monoxide, referred to as CO, is a colorless, odorless gas that is produced during combustion of coal and other fuels. CO fumes are toxic and can be fatal.

The DVC 500 is a closed loop system spe- cially designed to prevent the escape of CO and other combustion products from the stove.

Even though this stove is designed to be as safe as possible, it is important that you install a CO detector. This is true for oil, gas, or wood burning products as well.

CO detectors are very sensitive and may sound an alarm for fumes other than CO or CO from sources other than the stove such as car or lawn mower exhaust.

If the alarm sounds

1.Increase ventilation by opening windows or doors.

2.Make sure the stove doors and hopper lid are closed and latched.

3.Check stove for electrical power and normal operation.

4.Check for false alarm.

(Never sleep in the same room with any coal burning stove.)

Wet Coal

Freshly delivered coal is watered down to elimi- nate dust when loading and unloading. Wet rice coal does not flow as well as damp or dry coal. We do not recommend burning wet coal; how- ever, we realize if it's the only coal you have, it is better to burn it than be cold. If you must burn wet coal, the feed rate must be increased in order to get the same size fire. As the wet coal in the hopper dries out, the feed rate must be decreased. Loading wet coal once or twice a year will not damage your stove as long as it is hot and burning. The damage is caused when the hopper has wet coal in it when the stove is cold. This will cause rust and corrosion and it is totally the operator’s fault. Usually after the coal dries for three or four days, depending on conditions, it will flow very well and feed properly. Feed rate will be the same as with dry coal.

Always Empty Hopper

Always empty the hopperwhen 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 could result. This will be considered neglect and will void the warranty on those parts. Always check to see that moving parts are free before using, if the unit has not been burned for a period of time. This can best be determined by watching the cam block and pusher arm inside the right rear side door.

Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liq- uids to start or “freshen up” a fire in this heater. Keep all such liquids well away from the heater while it is in use.
