the sides with the clean-out tool the loose fly ash will drop out of the sides to the bottom of the burn
area. This needs to be done once a week.
Pull the lower front ash cleanouts out and scrap any fly ash down into the pedestal ash pan. Push them
back in all the way. This needs to be done every couple days or when unit fills up with ash.
9 While you are tapping the side heat exchangers, we recommend that you turn the draft lever all the
way open for a minute or two and put the unit on high fire. This will allow the unit to self-clean the
heat exchanger area, the draft fan and exhaust chimney pipe.
9 If a clinker ball develops in the firepot, scrape it out with the clean-out. You may have to do this once
or twice a day depending on the moisture content of the corn. If this is not cleaned out, it could cause
the fuel stirrer to jam. Clinker balls are a direct result of excessive corn moisture and they do not
indicate a problem with the stove. AES highly recommends our additive called “Clean Burn” be
added to your corn to eliminate these clinkers. Contact your local Magnum 7500 reseller for
availability and cost.
9 Open the stove doors and wipe the inside of the glass with a damp cloth as needed.
9 The ash pan needs to be checked daily to make sure that the ash has not built up to the bottom of the
firepot area. DISPOSAL OF ASHES: Ashes must be placed in a metal container with a tight fitting
lid. The closed container can only be placed on a non-combustible surface well away from any
combustible material. If the ashes are not disposed of by burial in soil or otherwise dispersed, they
need to be retained in the closed container until all ashes have thoroughly cooled.
SPECIAL CLEANING/OPERATIONAL/INSTALLATION INSTRUCTIONS:
CREOSOTE – FORMATION AND NEED FOR REMOVAL: With the low operating temperatures of
the Magnum 7500 furnace and if the venting is on an exterior installation, creosote may form. Creosote is
a tar –like substance combined with other organic vapors, which combine with expelled moisture to form
creosote. The creosote vapors condense in the relatively cool venting. As a result, creosote residue
accumulates on the venting lining. When ignited this creosote makes an extremely hot fire. Inspect the
venting at least twice monthly during the heating season to determine if a creosote buildup has occurred.
If creosote has accumulated it should be removed to reduce the risk of a venting fire.
It is important to establish a routine for the storage of fuel, care of the appliance, and firing techniques.
Check daily for creosote buildup until experience shows how often cleaning will need to be performed.
The hotter the heat setting on the furnace the less creosote is deposited so it will take more frequent
cleaning in mild weather than in cold weather when the heat settings are higher. A mid range heat setting
is more acceptable than a low setting to reduce the amount of creosote buildup.
It is very important to have a clearly understood plan to handle a venting and/or hopper fire. It is highly
recommended to have the fire department and police department numbers close by.
On the model 7500 furnace you need to make sure that the clean-out plates are in the closed position.
Push the front (2) clean-out slides all the way in and make sure that you have replaced the left & right
clean-out plates that are located on the inside of the unit. (These plates are located inside the firebox to the
left and right of the firepot in the lower corners of the firebox.) If these plates are not in the closed
position the unit will burn dirty. The ash pan door needs to be locked in place after emptying. If the door
