Masonry Chimneys have several positive

attributes: If properly built, they are quite

durable, and most homeowners consider

them more attractive perhaps than a non-

enclosed factory built chimney. And, if

the chimney is located within the connes

of the house (that is, not attached to an

exterior wall), its mass alone will store heat

longer and continue to release the heat

long after the re has died. Masonry chim-

neys have many disadvantages though.

Masonry chimneys constructed on an

exterior wall are exposed to cold outdoor

temperatures, promoting greater heater

loss, higher accumulations of creosote,

and reduced draft which leads to poorer

heater or furnace performance.

When considering a masonry chimney,

round tiles are preferable to square or

rectangular, as round tiles have much

better airow characteristics and are far

easier to clean. Unfortunately, most North

American chimneys use square or rectan-

gular tile liners that are really designed for

open replaces, not stoves or furnaces. Of

most importance, second only to overall

chimney height, is the diameter of the ue

liner itself. In most instances, it should be

sized to the appliance; i.e., 6” ue outlet

on the appliance requires a 6” ue. The

inner diameter should never be less than

the ue outlet diameter and should never

be greater than 50% of the appliance

ue outlet. For example, do not expect a

wood burning stove or furnace to function

properly if installed into a chimney with a

ue liner greater than 50% the appliance

outlet -- such as a 6” ue outlet requires

a 6” diameter for optimum drafting, but

can function well with an 8”, but becomes

borderline beyond 8” diameter.

Masonry chimneys built of concrete blocks

without ue liners of at least 5/8” reclay

do not meet modern building codes. A

solid fuel appliance must not be joined

to a chimney ue which is connected to

another appliance burning other fuels.

If your chimney has a typically oversized

ue liner of 8x12 inches or greater, or if it is

unlined, it will be necessary for you to reline

the chimney, using many of the modern

approved and economical methods such

as stainless steel, castable refractory, or

properly sized reclay linings.

If you have any question regarding vent-

ing your appliance, feel free to contact

the factory at the address and phone

number on this Owner’s Manual. You may

also contact NFPA (National Fire Protection

Association) and request NFPA Standard

211 (1984 Edition). Their address is Battery

March Park, Quincy, Massachusetts 02269.

Another helpful publication is NFPA Stan-

dard 908, available at the same address.

Specify 1984 Edition on either of the above

publications.

In the unlikely event that your heater “overres”

(a condition evidenced by elbows, stove pipes,

and connectors glowing red in appearance or

otherwise discoloring), then your installation

is subject to excessive draft created by either

a chimney too tall or too great in diameter in

conjunction with its height, or some other factor

of an indeterminate cause. In this event, you

should install a barometric draft regulator. Such

installation will preclude any over-ring and/

or any hazardous consequences of potential

overring.

Barometric draft regulators are generally avail-

able where you purchased your stove or may

be ordered directly from United States Stove

Company at a nominal charge.

to a near closed position - but leave the ash

pit damper at least partially open to prevent

the re from going out. Adjust the stove pipe

damper to reduce the draft on the re. With an-

thracite there will be short blue ames above

the coal, except when the re is started or a

new charge is added. If, however, there is no

ame then the re needs more air from the bot-

tom (unless it is near the end of its burn cycle

and needs to be recharged).

Only when the coal is burned down to half its

original depth it is time to add fresh coal. When

doing so, open the stove pipe damper and turn

the thermostat damper to high, which will al-

low the re to burn off any accumulated gases.

Open the feed door, and with a small rake,

hoe, or hooked poker pull the glowing coals

to the front of the rebox. Try not to disturb

the re too much. Next, add a fresh charge

to the back being careful not to seal off the

top. Close the feed door, but leave the spin

damper (or thermostat) open for a few minutes

until the volatile gases have burned off. It is not

necessary to shake down the ashes each time

you refuel the furnace. Experience will be your

best teacher.

BANKING THE FIRE:

For extended operation, such as overnight, the

re will need to be banked. To do so heap coal

up along the sides and back of the rebox so

that the re gradually burns it over a longer

period of time. The intensity of the re will also

be reduced without letting it go out. Follow the

same procedure as for refueling. If possible,

avoid shaking, as a heavier layer of ash will

help reduce the intensity of the re during this

time. After loading, let the re establish itself for

about 30 minutes. Then close your damper and

automatic control to the point where the house

does not become too cold. It is important that

you begin banking early enough before retiring

or leaving that you can make necessary adjust-

ments after the re is well established.

To revive a coal re that is almost out, (1) open

the ash door and stove pipe damper and close

the spin damper under the door to get a good

draft through the grate. (2) place a thin layer of

dry coal over the entire top of the re. DO NOT

POKE OR SHAKE THE FIRE AT THIS TIME! (3) after

the fresh coal has become well ignited shake

the grate (just a little), refuel.

Wish your blower would turn ON and OFF as

the heater gets warm and cold? It can with

this optional kit from U.S. Stove. It connects in

line with your power supply cord and mounts

to the back of the heater. When the snap disc

reaches 120 degrees, the blower automatically

turns ON and turns itself OFF if it reaches 90 de-

grees. See your Dealer for details or call U.S.

Stove directly.
