CARE AND OPERATION
FUEL DELIVERY RATE
The feed rate switch manages the fuel delivery rate by con-
trolling the amount of time the auger motor will run as fol-
lows:
Feed Auger Auger
Rate Motor "ON
Setting ON / OFF Time"
Time Trim
(seconds) (seconds)
Low = 1.9 on / 1.6 to 4.5
4.2 off seconds
(+/- 5%)
High = 1.9 on / 2 1.6 to 4.5
off
seconds
(+/- 5%)
* Feed rates are approximations only. Actual feed rate
will vary depending on size, quality and length of fuel
used and variations in line voltage.
♦ Estimated heat input based on fuel value of 8,400 BTU
per lb. of fuel.
Note: It is normal for some ash to build up on the inner
glass surface at the lower burn settings.
INITIAL START-UP / EMPTY HOPPER OR FEED TUBE:
During an initial start-up, or in the case where the hopper
has run out of fuel, it will be necessary to prime the auger
feed system.
To prime the auger feed tube:
1. Ensure all packing material and foreign objects are re-
moved from the hopper. Fill the hopper with recom-
mended pellet fuel and plug the stove into the wall out-
let.
2. Move the Heat Output switch on the control panel to the
"HIGH HEAT" position to activate the auger and blow-
ers.
3. Look through the combustion chamber door and when
you can see the first pellets dropping into the grate, the
auger is fully primed. This will take up to 10 minutes.

STARTING YOUR PELLET STOVE
1. After the auger is fully primed, adjust the Heat
Output switch to the "OFF" position.
2. Place a small amount of an approved (non-
volatile) gel fire starter on top of the pellets in the
UltraGrate (if chips are used as firestarter, place
chips in UltraGrate first then place pellets on
top). Consult with your authorized Lennox Hearth
Products dealer for approved fire starting prod-
ucts). DO NOT USE FLAMMABLE LIQUIDS TO
START YOUR STOVE.
3. Light the fire starter in the UltraGrate with a
match and close the door.
4. After approximately 10 seconds, move the Heat
Output switch on the control panel to the "LOW
HEAT" position. You will notice that the fire will
become active and there will be air coming from
the heat exchanger tubes and pellets will now be-
gin to feed into the UltraGrate.
5. After the fire is burning well, adjust the Heat Out-
put switch to the desired setting. Adjust the
damper control if necessary for proper combus-
tion. Look for a brisk, bright yellow to whitish
flame.
Remember, different brand fuels feed at different
rates.
TURNING OFF YOUR STOVE
Move the Heat Output switch to the "OFF" position.
This will stop the fuel feed and any remaining fuel in
the grate will safely burn up. The blowers will con-
tinue to run until the stove has cooled off sufficiently
and will then shut off automatically.
