Are the air outlets plugged?
Primary combustion air is provided through the
combustion air outlets in the firebox. The air outlets must
not be plugged or obstructed for the outdoor furnace to
operate correctly. If it appears the combustion air outlets
are plugged or restricted, refer to the Complete Firebox
Cleaning Procedures section. If after cleaning each
combustion air outlet, air flow is still blocked, inspect
the primary combustion air elbow. Refer to section 3-14
Primary Combustion Air Elbow for the procedure.
Is there creosote and/or ash inside the
airbox?
Creosote, ash, or even coals in the airbox is an indication
that the outdoor furnace has not been maintained and/or
operated properly. Especially important to the operation
and efficiency of the outdoor furnace is unimpeded air
flow throughout the entire system. Refer to Operating the
E-Classic for Maximum Efficiency and Performance for
a detailed explanation of how the E-Classic is designed
to operate.
Following are possible causes for creosote and/or ash
in the airbox:
1. One or more combustion air outlets are covered -
If the level of coals and ash in the firebox is allowed
to accumulate over the combustion air outlets,
normal air flow can be blocked and could force
coals and ash back into the airbox. Remove enough
ash so the combustion air outlets are not covered.
Review the Operating Instructions section for more
information.
2. Bypass door not operated correctly - The function
of the bypass door is to prevent the buildup of gases
in the firebox in certain situations by venting them
out through the chimney.
An example is when adding wood to the outdoor
furnace with a very hot bed of coals or a raging fire
in the firebox. If after closing the firebox door, the
bypass door is closed too quickly, the fire can actually
be put out. Gases will continue to accumulate in
the firebox until they re-ignite, forcing smoke (and
ash and coal, if above the air outlets) back into the
airbox. This is an example of why it is important
to always wait 15 seconds after closing the firebox
door before slowly closing the bypass door.
CAUTION
Always wait 15 seconds after closing the firebox
door to close the bypass door and always close
the bypass door slowly. Never slam the bypass
door shut.
TROUBLESHOOTING OTHER SITUATIONS
A. OUTDOOR FURNACE IS NOT OPERATING
CORRECTLY
1. Out of wood - Add wood as necessary. Use correctly
sized, seasoned wood.
2. Mixing channel (area directly below the charge
tube) obstructed - Inspect and clean as required.
3. Combustion air outlets obstructed - Clean as
required to prevent the combustion air outlets from
being obstructed.
4. Combustion air fan obstructed or not running -
Check the screen over the fan inlet and the inside of
the fan for any obstructions.
5. Airbox leaking - The airbox cover must be properly
secured. Determine the cause and correct.
6. Primary air solenoid closed - If the primary air
solenoid is not operating properly, determine the
cause and correct.
7. Reaction Chamber, heat exchanger or the
chimney plugged - If the Reaction Chamber, heat
exchanger or chimney are plugged, determine the
cause and correct.
8. Door open - If the display on the controller indicates
DO, close the firebox door. Make sure the firebox
door is properly latched and check the condition of
the firebox door seal (Fig. 67). If it is not sealing
properly (indicated by a uniform indentation),
replace the seal. If firebox door does not close
tightly, adjust using the appropriate procedure (see
Owner Serviceable Items).
