1. Fines are small pieces of broken pellets (sawdust). Fines

do not ow easily and often build up on the hopper funnel

bottom angles. These nes can be pushed into the feeder

opening and then ll the hopper with pellets. As the system

works, they will be burned.

2. The "TEST" cycle will operate the feed 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 rebox low pressure switch will not allow the auger

motor or the igniter element to operate if the view door is

open.

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

different pellets, set the Feed Limit to #4, Figure 4.6 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 holed surface downward into the burn pot. When the

stove feeds, these scrapings will be pushed out by the

feeder.

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 Limit # 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.

Figure 4.7. If the ash line is larger than 1", turn the Feed

Limit 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 during normal operation, the

ash bed will be larger.

NEVER USE GASOLINE, GASOLINE-TYPE LANTERN

FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR

SIMILAR LIQUIDS TO START OR 'FRESHEN UP' A FIRE

IN THIS HEATER. KEEP ALL SUCH LIQUIDS WELL

AWAY FROM THE HEATER, WHILE IN USE.

BURNING GARBAGE, USE OF IMPROPER FUELS,

FIRE STARTERS OR ALTERING THE STOVE FOR

HIGHER HEAT OUTPUT MAY CAUSE DAMAGE TO

THE STOVE AND COULD RESULT IN A HOUSE FIRE.

USE ONLY APPROVED FUELS AND FOLLOW ONLY

THESE OPERATION GUIDELINES.

cleaning and inspection

D. Glass Maintenance

The glass used in your stove is manufactured to exact

standards to withstand the high heat of the re, but like all

glass, it must be treated with common sense and care. Never

abuse the glass by slamming the door shut or striking the

glass with a heavy object. If the glass is broken or damaged,

do not operate the stove until it has been replaced.

scrapethe burnpot toremove carbon buildup.A vacuum

cleanerishandytoremovetheresidue.Besurethestove

iscoldifyouuseavacuum.

Carbonbuildupcanbescrapedloosewiththereburning

usingthespecialtoolprovidedwithyourstove.Scrapethe

oorandsidesoftheburnpot.Thecarbonwillbepushedout
