Weekly Maintenance

INSTALLATION AND OPERATION MANUAL

MF3700, MF3800 Models

•Complete the daily maintenance by checking the seal on the doors. Look for pellets that may have been left behind during loading. Check that each of the door seals are flush with the stove and sealing properly.

•The fire pot and the area around it are cleaned using the special tool provided with the stove and the ash cleaning vacuum. It is important to remove any unburned pellets that may have fallen behind the burn pot.

•To clean the fire pot with the cleaning tool, remove the fire pot by unscrewing the firepot cleaning rod from the fire pot. Remove the rod and the firepott. Remove the fire plate by lifting it out of pot holder (Figure 28). Brush all of the ash from beneath the fireplate into the ash pan.

•Remove the ash pan and dump the ash into a metal container.

•Cleaning of the exhaust system will depend upon the ash and debris content of your fuel. If your fuel has a high ash content and/or significant debris in it, the exhaust system will require weekly cleaning. Cleaner fuels will allow for monthly cleaning of the exhaust system. Clean out tees in the exhaust system make this task much easier.

NOTE: A clean unit burns efficiently and will remain trouble free!

•Moving parts inside of the cabinet may cause injury. Do not operate unit with panels removed or open.

THE CONTAINER SHOULD BE PLACED ON A NON-COMBUSTIBLE FLOOR, WELL AWAY FROM COMBUSTIBLE MATERIALS, PENDING FINAL DISPOSAL. iF ASHES ARE DISPOSED OF BY BURIAL IN SOIL OR OTHERWISE LOCALLY DISPERSED, THEY SHOULD BE RETAINED IN THE CLOSED CONTAINER UNTIL ALL CINDERS ARE NO LONGER WARM.

MONTHLY MAINTENANCE

•Remove the top baffle inside the firebox and clean the fly ash and soot on all exposed parts using a steel brush and ash cleaning vacuum. The use of a shop-vac is not recommended. Talk to any authorized dealer for information about the ash cleaning vacuum.

SEASONAL CLEANING

Once every year you must clean out all of the fuel in the hopper, firebox area, ash pan and fire pot area. Corn and pellets can accumulate moisture over the summer months causing the unit to rust and the fuel to mold.

It is recommended that prior to shutting down the unit in the spring it is run on the high setting for about six hours to help clean out the heat exchanger system, venting system and fire box area.
