AES Technical Bulletin # F-0404 Date of Issue 02/13/2006
unhooking the outside air and opening a door or window for a few hours to see if the combustion air is an
issue.
7.
Incorrect Venting for exhaust: If the venting has more than 2 elbows or has an equivalent length of more
than 10 feet, it is recommended to go with 4” venting. If the venting is restricted by outside elements it
has to be changed. Corrective testing would need to be done by taking the unit out of the environment
that it is in and making sure that it does run correctly. If the glass gets dirty quickly (under 1 hour) the
venting is not correct. MagnuM 6500 Furnaces after January of 2006 must use 4” venting.
8.
Environmental conditions: In most cases, the home itself is causing the problem. If the unit is being used
in any way to supply air to the home, it will not work correctly. If the home has not been balanced so that
there is no negative pressure, it will have to be done or the unit will not operate on the higher settings and
may not operate correctly on the lower settings.
9.
Draft/Exhaust blower: If the exhaust blower is not operating correctly it will affect the fire. Corrective
action would be to do an air flow test (should be around 75 cfm) and an amp draw test (should be around
.95 amps). Always check the label on the product for correct cfm and amps. Check for gasket leakage
between the draft/exhaust blower and the housing.
10. Plugged heat exchanger/plugged venting: If the venting or heat exchangers or draft/exhaust blower is
plugged (normally caused by lack of maintenance, improper combustion air, improper venting, negative
air pressure, and wet fuel) this will cause the firepot to fill up prematurely on higher settings. Corrective
action would be to identify these items and correct.
11.
It is important to daily move the heat exchanger cleaner rod back and forth to eliminate the plugging of
the heat exchangers. Do not force the heat exchanger rod as you will bend or break the heat exchanger
plate. This is a time consuming and costly repair that his not covered by warranty. If you have plugged
your heat exchanger tubes you might have to take the appliance outside and wash out the heat
exchanger area. Consult your local dealer for inspections and corrective action to be taken.
12.
Operator Error: It is important that proper installation, maintenance and operation practices are followed.
If the appliance is not installed correctly, proper fuel used or proper operation ignored, the firepot will fill
up after a short time of operation. Continued use with the above problems and the appliance will plug up,
venting will become plugged, draft blower could become plugged and extensive damage to the appliance
could occur. The appliance is not covered under warranty for operator error, lack of maintenance and
improper installation.
13.
The unit will burn fine on the higher settings for about 8-12 hours and then it needs the clinker knocked
down or taken out. The longest that the unit will burn without clinker removal would be app. 24 hours if all
conditions are perfect and proper fuel is being burned. The unit works the most efficient on the #2-3
setting for maximum heat impact but will burn on 4-5 if operated and installed correctly.
The MagnuM 6500 Furnace has been tested to perform at the BTU level that is on the test plate. It has been
tested to run according to the operations manual guidelines. If the unit is not installed, vented or operated
according to these requirements, it will not perform properly. It is the responsibility of the homeowner to contact
the dealership to make sure that all of the items listed above are checked out and are not affecting the
performance of the furnace. Anything less than this could cause damage to the unit and or the customers’ home.
Clinker removal: The clinker needs to be removed when it builds up to app. 1” thick. This normally would be done
every 12 hours or so. The clinker can be removed with the fire burning by tapping lightly on the top of the firepot
and then placing your removal tool underneath the clinker and roll the clinker toward the back of the firepot. Once
the clinker is loose you can tip the clinker to the side using a fireplace tong to pour the fire back into the firepot
and then safely remove the clinker. This action will take a little practice to get good at doing it.
Dispose of the clinker by either placing it on either side of the firebox chamber so that it cools and crumbles into
the ash pan or take the clinker out and place in a fireproof container.
Proper operation of the MagnuM 6500 Furnace is essential. Please contact your local dealer to get questions
answered and proper operating techniques.
