Dampers On Stove Pipes; Installation Examples - United States Stove Company 1602R Installation/operator’s Installation & Operator's Manual

IMPORTANT INFORMATION FOR ALL
CONNECTOR PIPES
The connector pipe must be constructed and installed
so that it maintains clearances, keeps condensation and
creosote within the pipe, and is capable of withstanding
a 2100°F degree chimney fire.
1. The connector pipe should slant down toward the fur-
nace a minimum of 1/4" to the foot. At no time should
the pipe turn downward toward the chimney or run
horizontal.
2. There should be no more than two 90 degree elbows.
3. The connector pipe should never be longer than six
feet. If it is absolutely necessary to make a run of more
than six feet (not recommended) use extra support
brackets every 3 feet.
4. The connector pipe should never be reduced to a
smaller size than flue opening on the furnace.
5. The connector pipe should not block the flue of the
chimney or extend into it in any way.
6. A good airtight thimble should be used to hold the con-
nector pipe in the chimney. It should be constructed
so the connector pipe can be removed for cleaning.
7. The connector pipe should not leave the heated por-
tion of the building to reach the chimney.
8. The connector pipe should not pass from one story to
the next before entering the chimney, nor should it pass
through any closed or enclosed space.
9. The connector pipe and any elbows must be of 24
gauge or greater.
10. The connector pipe should not be located near or in
a walk way or well traveled area.
11. All male ends of connector pipe should run or point
towards the furnace.
12. Install a cast iron adjustable damper in the first joint of
the connector pipe, nearest to the flue collar.

DAMPERS ON STOVE PIPES

When burning coal, we recommend a Barometric Draft
Damper be installed at a safe convenient place between
chimney and your furnace preferably less than 3' from the
flue collar.
When you have installed the connector pipe between
your furnace and the chimney, tap the pipe hard with
your fingernail. Remember the sound it makes - it will be a
"ting" echoing inside the stove pipe. If later you tap and
hear a muffled thud, you are building up soot in the pipe
and should clean it. This pipe should be cleaned at least
once or twice during the heating season.
DO NOT CONNECT TWO HEATERS TO THE SAME CHIMNEY
FLUE. The National Fire Prevention Association recommends
that wood burning appliances vent into a separate flue from
gas or oil furnaces. If such an installation is contemplated,
first check with a local building inspector to find out if a
separate flue for a wood burner is required.
Use of a Barometric Draft Control (when burning wood) is
recommended ONLY in the event your chimney creates
excessive draft leading to an over-firing condition.
HEATED AIR DISCHARGE
The Ashley furnace is designed for use as a supplemental
heating source. When used as a supplementary furnace,
it is connected in conjunction with an oil, gas, or electric
furnace to the existing duct work which distributes the
heated air into several rooms and/or areas.

Though United States Stove Company expressly Does Not
recommend the use of its furnaces to be installed and/or
used as a free-standing heater, it is possible to achieve a
reasonably safe and functional installation IF certain stan-
dard procedures are followed. The following are guidelines
only and are intended to enable the furnace user to obtain
reasonable efficiency from his furnace, and with due re-
spect to safety when installing as a "free-standing heater".
If installed correctly, and in accordance with the instructions
found in this manual, your warm air furnace may be installed
as a "space heater" within living quarters, cabins, garage,
or workshop. Please adhere to the following:
1. The use of a cold air return and/or filter box is mandatory.
This will not only increase your blower life and provide
filtered air, it will also help prevent the blower or blowers
from "capturing" heated air exiting from the top of the
furnace heat outlets.
2. If installed as purchased , without directing the heat
away from the furnace itself, it will simply sit and cycle,
turning the blowers off and on. The thermostat may not
function properly.
3. All larger furnaces (or those with multi-speed blowers)
absolutely require BACK PRESSURE to prevent premature
motor winding failure. If allowed to operate at high RPM
(As in "FREE AIR" mode - no duct work or flow restrictions)
the windings overheat, insulation melts and the motor
simply burns up - not covered under warranty.
CONNECTING HOT AIR DUCT
TO FURNACE
We strongly recommend that the hot air duct work be
installed by a home heating specialist. If doing the instal-
lation yourself, before you decide which installation will
best suit your needs, consult a qualified heating technician
and follow his recommendations as to the safest and most
efficient method of installation.
The following illustrations are the ONLY acceptable con-
figurations when installed with existing oil or gas furnaces.

INSTALLATION EXAMPLES

INSTALLATION #1
With this installation, a back draft damper (optional) is in-
serted into the heat run before the plenum of the existing
furnace to prevent air from the existing furnace to blow
back into the furnace when it is not in use. When a back
damper is employed, it should be located as close to the
existing furnace plenum as practical.
