Fan Options - Cumberland Stove Works MF3800 Installation And Service Manual

FAN OPTIONS:

The voltage to the combustion and convection fans can be
offset. The combustion fan offset at the factory is set to 3 or 4.
This setting is selected at the factory because it generates a
vacuum within the stove at a range of 0.10 to 0.25 W.C. after
10 minutes during the STARTING FIRE sequence. If the stove
does not burn correctly, make sure that the sealing surfaces
of the firepot are secure and the vacuum within the firebox is
within this specified range during the STARTING FIRE screen.
DO NOT CHECK THE VACUUM DURING THE TEST MODE. If the
vacuum during the STARTING FIRE screen is less than 0.10 or
more than 0.25, the combustion fan voltage offset should be
changed.
To get to FAN OPTIONS, the stove must be unplugged first.
Wait 5 seconds and plug the stove back in. The display will
first read "Ardisam v1.00".

After 3 seconds, the screen will read "MF3700 / 3800 Ver 1-0-
**" (** denotes the version of software). When the screen
reads this way, hold down the SCROLL key.

After 3 seconds, the screen will read "<--| MF3700, MF3800
(IGN)" (One above the other). Remove your finger from the
SCROLL button, then hold down the ON and OFF buttons at
the same time.

INSTALLATION AND SERVICE MANUAL
After three seconds, the screen will read "FAN OPTIONS".
Then, after 5 more seconds, the screen will read "FAN
OPTIONS SAVE". Every 5 seconds the fan option selected is
saved to memory. The combustion fan voltage offset (CB) can
be changed by pushing the FAN UP key. The convection fan
voltage (CV) can be changed by pushing the FAN DOWN key.
FAN OPTIONS
Scroll through the offsets until the correct setting is reached
for the installation at hand. Wait until the screen reads "CB
OFFSET*", "CV OFFSET* SAVED". When the screen reads
"SAVED", unplug the stove and test the vacuum again during
the STARTING FIRE screen after 10 minutes.
CB OFFSET*
CV OFFSET*
The vacuum in the firebox should be 0.10 to 0.25 W.C.
during the STARTING FIRE phase. Variables that contribute
to changing fan offsets include voltage drop in the cord
supplying power to the stove, low voltage supply from utility,
venting configurations that either limit flow or supply too
much natural draft, and extreme cold temperatures that
hinder motor RPM.
NOTE: The CV OFFSET is set at 0 and should be turned up as
high as 9 to move more room air.
The fan options and voltage offsets are not intended to
compensate for a poorly maintained or dirty stove. For this
reason, the voltage offset is not in the this manual. The
voltage offset can only be performed on a clean stove with
clean venting, a clean blower, clean exhaust manifold, clean
firepot, clean fireplate and a clean potholder.
NOTE: When you have completed your work in the FAN
OPTIONS, the only way to exit the FAN OPTIONS sequence
is to unplug the stove. You will then need to go through the
start-up process again, reigniting the stove and selecting
the appropriate fuel range.
