Creosote - Formation and Need for Removal

When wood is burned slowly, it produces tar and other

organic vapors, which combine with expelled moisture to

form creosote. The creosote vapors condense in the rela-

tively cool chimney flue of a slow burning fire. As a result,

creosote residue accumulates on the flue lining. When ig-

nited this creosote makes an extremely hot fire.

The chimney connector and chimney should be inspected at

least twice monthly during the heating season to determine

if a creosote buildup has occurred.

If creosote has accumulated, it should be removed. Failure

to remove creosote may cause a house fire. Creosote may

be removed by using a chimney brush or other commonly

available materials.

Chimney fires burn very hot. If the chimney connector should

glow red, immediately call the fire department, then reduce

the fire by closing the air damper and pour a large quantity

of coarse salt, baking soda or cool ashes on top of the fire in

the firebox. CAUTION: A chimney fire may cause ignition of

wall studs or rafters which you thought were a safe distance

from the chimney. If you have a chimney fire, have your

chimney inspected by a qualified person before using again.

CHIMNEY MAINTENANCE

SERVICE HINTS

Do not expect a heater to draw. It is the chimney that creates

the draft. Smoke spillage into the house or excessive buildup

of water or creosote in the chimney are warnings that the

chimney is not functioning properly. Correct problem before

using heater. Possible causes are:

The connector pipe may be pushed into the chimney too

far, stopping the draft.

Do not connect two heaters into the same chimney flue.

The chimney used for a heater must not be used to

ventilate the cellar or basement. If there is a cleanout

opening at the base of the chimney, It must be closed

tightly.

If the chimney is operating too cool, water will condense

in the chimney and run back into the stove. Creosote

formation will be rapid and may block the chimney.

Operate the heater at a high enough fire to keep the

chimney warm preventing this condensation.

If the fire burns well but sometimes smokes or burns

slowly, it may be caused by the chimney top being lower

than another part of the house or a nearby tree. The wind

blowing over a house or tree, falls on top of the chimney

like water over a dam, beating down the smoke. The top

of the chimney should be at least 3 feet above the roof

and be at least to 2 feet higher than any point of the roof

within 10 feet (Fig. 6).

OPERATING INSTRUCTIONS

Wood Fuel

Use Hardwood that has been split and air-dried to obtain

maximum burning efficiency.

Lighting Instructions

1. Open door and place paper and kindling in the firebox.

2. Light the fire and close the door until the kindling is

burning.

3. Open the door and add fuel as desired.

Extended Operation

1. Fuel should be added in small amounts to give more

complete combustion and uniform room temperature.

2. Empty the ashes regularly. Do not allow ashes to

build up. Dispose of hot ashes properly in a metal

container with a lid.

WARNING!

NEVER STORE FLAMMABLE LIQUIDS,

ESPECIALLY GASOLINE. IN THE

VICINITY OF THE HEATER.

CAUTION!

OVERFIRING THE APPLIANCE MAY

CAUSE A HOUSE FIRE. IF A UNIT OR

CHIMNEY CONNECTOR GLOWS, YOU

ARE OVERFIRING.

CAUTION!

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 IT IS IN USE.

WARNING!

OPERATE ONLY WITH THE FEED DOOR FULLY

CLOSED.
