TROUBLESHOOTING

*SMOKES OUT FUEL DOOR WHEN OPEN

1. The primary air control is closed.

2. The chimney is too cool. Set the primary air control on HIGH setting with start-up control OPEN for a few minutes before opening the fuel door.

3. Excess creosote will not only restrict your draft but it will create a risk of a creosote fire. Strictly adhere to maintenance requirements as outlined in this man- ual. If excess creosote has built up on the inside of the firebox sides and door, burn a small hot fire at in- tervals that are more frequent with start-up control open and primary air control on high for a few min- utes.

4. Deposits may have built up in the chimney and are restricting the draft, or the spark arrester on top of the chimney may be plugged.

5. Chimney diameter too large or too small to provide adequate draft.

6. The house is too airtight (usually takes 20 to 30 min- utes for problem to appear as stove lowers air pres- sure in house). Crack a window open or provide an outside source of air near insert.

7. Insufficient vertical height to chimney to achieve adequate draft.

DOES NOT PRODUCE ENOUGH HEAT

1.Using green or insufficiently cured wood.

2.Excessive draft.

3.High ceilings (heat rises quickly, but can be recircu- lated by a well-placed ceiling fan with a winter / summer switch).

4.The area to heat is too large (square foot heating estimates are based on "average" climates and home design.)

5.There is an obstruction in the chimney.

6.The chimney or chimney cap is restricted by creo- sote preventing enough draw to sustain a "high" heat output rate.

* DOES NOT MAINTAIN A FIRE

1.Soft wood does not burn as long or as well as sea- soned hardwood resulting in a short burn time.

2.Wood size too small. Burns at too rapid a rate.

3.The gasket seal on the fuel door or glass is leaking air. Repair or replace it if necessary.

4.Excessive Draft.

5.There may be an obstruction in the chimney.

* BACKPUFFING

1.Downdraft in the chimney (a special wind cap may be needed).

2.The house is too airtight (ventilation is needed).

3.Insufficient vertical height to chimney to achieve adequate draft.

ODORS

1.Creosote accumulation in firebox (brush out on next cleaning).

2.Chimney downdraft when stove is not operating (close the primary air control).

3.Paint curing on first several burns.

* DIRTY GLASS

1.Poor draft conditions.

2.Long burn periods at low draft settings.

3.Burning wet, pitchy or spongy wood.

4.Poorly arranged logs (too close to glass).

*Draft problems --If installing into a larger flue, it may be necessary to use a full-length liner to achieve adequate draft for the appliance. A draft gauge should read a minimum of .05" w.c. (inches water column) not to exceed .07" w.c. for optimum performance (See Draft Require- ments, page 5).
