Warnings - Harman DVC-500 Installation & Operating Manual

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 specially
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.
(Never sleep in the same room with any coal burning stove.)
wet Coal
Freshly delivered coal is watered down to
eliminate 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;
however, 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.
Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar
liquids to start or "freshen up" a fire in this heater. keep all such liquids well away from the
heater while it is in use.

warnings

Carbon monoxide (CO) Awareness
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.
Always Empty hopper
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 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.
