The End Of Season Shut Down List.
1. Allow the stove to run out of coal in order to extin-
guish the fire. This saves having to remove the coal
from the hopper manually and most importantly,
drives the moisture out of the stove that may be
present in the coal.
2. Perform all the steps of the 3 month maintenance
list.
3. Clean the glass as shown in fig.21.
4. Empty the fines tray and inspect the area for rust
and corrosion
5. Make sure the hopper is empty. Wet or damp coal
in the hopper will promote rust.
6. Remove the FSS Tube from the rear of the firebox
(fig.27) and clean the brass fitting going into the
firebox with a pipe cleaner. Reconnect tube.
7. The FSS line filter can be changed annually to
insure proper flow, however, it may only be neces-
sary if the filter is discolored.
8. Remember to cover the flue pipe over the summer
to block out rodents and birds. Place a note inside
the unit to remind yourself or others not to forget
to uncover the flue pipe before lighting a fire.
Prevent Rust
Summertime moisture and high humidity are
your stove's enemy. A clean stove will have less
fly ash and fines to absorb moisture and cause rust
and corrosion. Allowing wet coal to remain in the
fig. 26
hopper of a cold stove will promote the formation of
rust and corrosion. Some owners choose to spray a
light coating of oil on all internal workings and the
firebox as a rust inhibitor.
Annual Service
It is recommended that your DVC500 is serviced
annually by your trained Harman dealer. The best time
for this service is during a non-use period. You may
choose to combine this service with the end of season
maintenance.
