Maintenance21

The operation can also be performed when the unit is not burning by lifting the grate inserts out and removing the ash with a vacuum cleaner.

Remove baffle slide as shown and remove fly ash.

Annually:

The end of the heating season is the best time to perform annual maintenance. Rust and corrosion can form much faster in the high humidity of summer, so cleaning your VF 3000 will prevent those damages.

1.Remove all coal from the hopper

2.Remove all ashes

3.Remove and clean flue pipe

4.Check chimney and clean if necessary

5.Remove hopper and check for rust at bottom edges.

If rust is found, remove it with a file or sandpaper then paint the area with spray paint available at your Harman dealer.

6.Check the feeder for rust and corrosion where the hop- per fits into it.

7.Check pusher block to be sure it moves freely. This can best be done by shaking the adjuster rod. If it does not move freely, it should be removed and cleaned. Also remove any rust or corrosion from the area where the pusher block slides and spray with WD-40 or other rust preventing spray. To remove pusher block, remove cover, wing nut, adjuster and adjuster tube. Remove motor mount with motor in place and cord still attached. Swing pusher assembly up as high as it will go. Remove feed indicator from side with allen wrench. Now the pusher block can be removed. To reinstall, just reverse procedure. If the pusher block cannot be removed, call your Harman dealer.

WARNING- Risk Of Fire;

-DO NOT Operate with flue draft exceeding

-.10 in Water Column (-24.9 Pa.)

-DO NOT operate with fuel loading or ash removal doors open.

-DO NOT store fuel or other combustible material within specified installation clearance areas.

-INSPECT and clean chimney flue system and chimney connectors regularly.

Hopper Maintenance: Always empty the hop- per when not burning for more than a week. Pusher Block Maintenance: When left stand- ing for long periods with wet coal, the pusher block will rust and corrode, causing it to stop. 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. If the unit has not been burned for a period of time, always check to see if moving parts are free before using. This can best be determined by shaking the adjuster rod.

CAUTION:

- Inspect flue pipes, joints, and seals regu- larly to ensure that smoke and flue gases are not drawing into the dwelling.

-Cleaning of the heat exchanger, flue pipe, chimney, and draft inducer if used, is espe- cially important at the end of the heating season to minimize corrosion during the summer months caused by accumulated ash.

-DO NOT use chemicals or fluids to start a fire.

-DO NOT burn garbage, gasoline, naptha, engine oil, or other inappropriate materials.
