helpful hints
1. Fines are small pieces of broken pellets (sawdust). Fines do
not flow easily and often build up on the hopper funnel bottom
angles. You can push these fines into the feeder opening and
then fill the hopper with pellets. As the system works, they will
be burned. Or you can clean them out before filling the hopper.
2. The "TEST" cycle will operate the feeder motor for exactly one
minute. Turning to "TEST" again and again may load too much
fuel into the burn pot causing excessive smoke on start-up.
3. The firebox low pressure switch will not allow the auger motor
to operate if the view door or the ash pan door are open.
4. Adjust Feed Rate. If this is your first fire or you are trying different
pellets, set the feed adjuster to #4, Fig. 17. This is a conservative
number and will probably need to be increased. After you know
a feed rate setting that works well, use that setting. Remember,
if your feed rate is too high you may waste fuel.
5. This is usually a weekly maintenance procedure. Cleaning the
burn pot with the scraper with a small amount of new fuel in the
bottom is not a problem. First, scrape the ashes off the front of
the burn pot into the ash pan. Then, scrape the top surface of
the burn pot downward into the base of the burn pot. When the
stove is ignited these scrapings will be pushed out by the feeder
and burned.
6. The ash pan can hold the ashes from approximately 1 ton of
premium fuel. This means the ashes will only need to be emptied
a few times a year.
7. Setting the feed adjuster # for maximum burn: With the unit
burning in "AUTO", turn to "Stove Mode" and put the fan on
"H". Set the Temperature Dial to #7. Allow the unit to burn for
about 30 minutes and check ash on front of burn pot. Fig. 18.
If the ash line is larger than 1", turn the feed adjuster from #4
to #5. Allow another 30 minutes of burn time and check again.
If , at #6 setting, a 1" or less ash bed is not obtainable, it is not
a problem. The 1" ash bed is only a maximum burn rate and at
most normal settings the ash bed will be larger.

4. clean burn pot with scraper if necessary.
5. Fill burn pot with pellets, only level with front edge.
(Do Not Over Fill).
6. add starting gel on top of the pellets. Stir gel into pellets
for fast lighting.
