Figure 19 Feed system access through hopper
6. Problem : After several weeks of outstanding perfor-
m ance, the heater suddenly stopped and the red light
under the control knob cam e on. This light is the Hi
Tem p/Flue Indicator Light.
Solution: The Hi-Tem p/Flue Indicator light indicates
that fly ash has built up in the exhaust system and/or
there is a restriction in the exhaust/flue system . Check
the pipe system for excessive ash and clogging,
particularly the vent cap. Rem ove the clean out cap
on the tee and m ake sure that ash has not blocked the
exhaust air flow. This autom atic shut down in case of
flue clogging is a safety feature and if the shut down
occurs it m eans you have a problem and should
consult a service technician and/or clean your pipe
and heater thoroughly. If you feel the fly ash build up is
excessive, we suggest that you try another brand. In
m oist clim ates the pellets and fly ash can actually
absorb m oisture from the air and create creosote and
a severe clogging problem . Keep this in m ind when
you store and handle your pellets. The heater warranty
does not cover the quality of the fuels used or the way
they m ay be handled either before or after you've
purchased them .
7. Problem : I press a “Run” button and the heater did
not start.
Solution: Check for AC power. The autolite system
requires 110V AC power to operate. If heater only
12VDC battery power, follow m anual light procedure. If
AC power is available, clean burn pot for heavy ash
deposit. Heavy ash deposits will act as insulator and
not allow pellets to light. Check autolite fuse located
on fuse panel to confirm fuse is not blown. Replace
fuse with 5 am p if required.
8. Problem : I started to add pellet fuel and the heater
went out.
Solution: The heater incorporates a safety switch
that will disable the feed system when the hopper door
is open. If fuel is to be added while heater is in
operation it m ust be accom plished with in several
m inutes of opening the door.
9. Problem : I turned off the switch and the heater kept
running.
Solution: This is norm al. The exhaust blower will
keep running until it cools down and then it will
autom atically turn off. This can vary by the tem pera-
ture the exhaust has reached and the tem perature of
the cooling air.
10. Problem : Feed system jam m ed.
Solution: This condition is caused by fuel contam inated
with hard m aterials such as rocks or m etal objects. To
correct this rem ove all pellets from hopper. Unplug
heater from any power source (12V & 110V). Rem ove
the (4) nuts with a 3/8" nut driver attaching access cover.
Carefully rem ove cover and vacuum out rem ain pellets.
Locate the object jam m ing auger and reassem ble. Plug
heater into power source and push “Run” button. W ith
hopper door open, press safety switch down and view
auger operation. If auger turns freely add fuel. And prim e
fuel system .
HI TEMP/FLUE RED WARNING LIGHT:
W hen the Hi-Tem p/Flue indicator light com es on (red lite
beneath control knob) it m eans a fault has been detected in
either the flue system , over tem perature, or fan/feed m otor.
Slow Flash Red Light - Indicates a blocked flue. Check flue
and clean out for built up ash deposits.
Solid Red Light - Indicates an over tem perature. Check the
air intake at rear of unit. Turn the feed trim down 25% to
reduce fuel rate.
Fast Flash Red Light - Requires unit to be unplugged to
reset. Indicates a feed m otor jam or fan m otor fault. Fan
m otor test would require running unit on “fan and clean” only
to determ ine if red light indication is repeated. If not, feed
system is jam m ed and requires the hopper access cover to
be rem oved and jam m ed m aterial to be rem oved. If this
condition continuos contact your dealer for service.
TRIM KNOB ADJUSTMENT:
Underneath the control knob you will find a sm all round knob
that will turn forward and reverse. This knob can control the
feed m otor rate. By turning the knob clockwise you can
increase the burn rate and by turning it counterclockwise you
can decrease the burn rate. Use this to change the overall
rate for different pellets. For instance, if the pellet has high
ash and burns dirty decrease the "trim " and if the heater
goes out on low or has low flam e increase the "trim ".
M ove this KNOB carefully! It is designed to fine tune your
LOW setting in the event you change brands of pellets
and/or live at a higher elevation.
