Make sure the unit is plugged into a 120 VAC, 60 HZ electrical 

source. The power light should be the only light lit.

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.
