Avoiding Smoke and Odors

Negative Pressure, Shut-down, and Power Failure:

To reduce the probability of back-drafting or burn-back in

the pellet burning appliance during power failure or shut-

down conditions, the stove must be able to draft naturally

AUTOMATIC START UP

Helpful Hints

1. Fines are small pieces of broken pellets (sawdust). Fines do not

ow easily and often build up on the hopper funnel bottom angles.

You can push these nes into the feeder opening and then ll the

hopper with pellets. As the system works, they will be burned. Or

you can clean them out before lling the hopper.

2. The "TEST" cycle will operate the feeder motor for exactly one

minute. Turning to "TEST" again and again may purge too much

fuel into the burn pot causing excessive smoke on start-up.

3. The rebox low pressure switch will not allow the auger motor

or the igniter element to operate if the view door or the ash pan

door are open.

4. Adjust Feed Rate. If this is your rst re 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 on 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 at maximum burn rate and at most normal settings the ash

bed will be larger.

Room Temperature Mode: This

setting, see below, will produce a

room temperature of 70 degrees

with the distribution blower at

medium speed.

This setting will produce a large viewing re without a

Helpful Hints

1. Fines are small pieces of broken pellets (sawdust). Fines do not

ow easily and often build up on the hopper funnel bottom angles.

You can push these nes into the feeder opening and then ll the

hopper with pellets. As the system works, they will be burned. Or

you can clean them out before lling the hopper.As the system

works, they will be burned.

2. The "TEST" cycle will operate the feeder motor for exactly one

minute. Turning to "TEST" again and again may purge too much

fuel into the burn pot causing excessive smoke on start-up.

3. The rebox low pressure switch will not allow the auger motor

or the igniter element to operate if the view door or the ash pan

door are open.

4. Adjust Feed Rate. If this is your rst re or you are trying different

pellets, set the feed adjuster to #4, Fig. 19. This is a conservative
