Starting A Coal Fire; Testing And Operating Procedures; Starting A Wood Fire - USSC Clayton 1602G Installation & Operator's Manual

GENERAL FURNACE OPERATION
After installation of the furnace is complete, it is ready for
operation. The Honeywell Limit Control, in conjunction
with a wall thermostat, operates the distribution blowers
and the draft blower on the front of the furnace. The limit
control can be adjusted to your desired blower On/Off
times. The factory settings are 100/150/200.
The wall thermostat setting operates the ON time of the
draft blower. If the temperature is below the setting on
the wall thermostat, the draft blower will come on. (Rec-
ommended setting at 5 to 10 degrees higher than other
heating thermostats.)
The first two set points on the limit control operates the
distribution blower(s). When the furnace plenum reaches
the second set point on the limit control, the distribution
blower(s) will come on. If the temperature falls to the first
set point, the distribution blower(s) will shut-off. The rocker
switch on the top of the junction box gives you the op-
tion to run one blower or two. If the switch is ON, both
blowers will come on when the plenum reaches the set
temperature.
When the furnace reaches the third set point on the limit
control, the draft blower will shut-off. The draft blower will
come back on if the temperature falls below the setting
on the wall thermostat.
TESTING
1. Check the draft blower by turning the room thermostat
up high enough so that the draft blower turns on. Then
lower the thermostat setting until you hear it shut off.
2. Use a sheet of newspaper to test your draft by placing
it inside the furnace and lighting it.
With completion of the tests above, you are ready to light
the furnace. Follow the operating steps.

STARTING A WOOD FIRE

Using Forced Air Draft
CAUTION: Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter fluid, or similar liquids to start or
"freshen up" a fire in the furnace. Keep all such liquids well
away from the furnace while it is in use.
1. Open spin draft cap on ash door.
2. Pull the slide baffle rod to the front position.
3. Open the fuel load door and light fire using kindling and
several sheets of newspaper, then close the furnace door.
The furnace door should remain closed for 5 to 10 minutes
in order to establish the fire. If the fire has established, you
are ready to load the furnace.
CAUTION: To prevent flame and smoke spillage, the slide
baffle must be pulled out and the fuel door must be cracked
for ten seconds before being fully opened.
Do not over fire your furnace! After you have become
familiar with its operating, you should know how much
wood to use.
4. Load the furnace, close the load door and push the slide
Baffle rod to rear.
5. Close the spin draft cap on ash door, leaving it cracked
about the diameter of a dime.

TESTING AND OPERATING PROCEDURES

6. The forced air draft cycles on demand from the wall
thermostat. Setting the U.S. Stove thermostat four degrees
higher than your existing thermostat is recommended. In
operation, the power draft blower will run until the U.S.
Stove thermostat temperature setting is reached. The
draft regulator on the forced air draft is preset at the
factory and should require no adjustment.
CAUTION: To avoid excessive temperatures, do not
operate with fuel door or ash pan open.

STARTING A COAL FIRE

If you burn coal, a forced air draft is required
Shut off FAD when fuel door is open
 Open smoke pipe damper all the way. Open all draft
controls on your 1602/1802. Pull the slide baffle forward.
 Place about 10-15 lb. of coal in on the shaker grates. It
should come up to about half of the first firebrick level.
 Place crumpled paper over the coal and crisscross a
couple handfuls of dry kindling wood 3/4" in thickness
on top of paper.
 Ignite the paper and close loading door. Wait about 30
minutes until coal fire is established before adding more
coal. NOTE: NEVER load coal over the level of firebrick.
 Close by-pass damper and set all draft controls to your
own needs. It may take 3 to 4 coal fires to determine
how your local coal and the Clayton Furnace reacts
together. Adjusts drafts accordingly.
 Loading with a good bed of coals in the morning - Open
by-pass damper.
1. In normal shaking, only rock the grates a small amount
to sift ash through. Do not agitate the fire bed too
often. This practice will waste coal. If glowing coal is
visible in the ash pan, you have shaken to much.
2. Remove all ashes every day from ash pit.
CAUTION: Ashes should be placed in a metal container with
a tight fitting lid. The closed container of ashes should be
placed on a non-combustible floor or on the ground well
away from all combustible materials pending final disposal.
If the ashes are disposed of by burial in soil or otherwise
locally dispersed, they should be retained in the closed
container until all coals have thoroughly cooled.
3. With your poker, push hot burning embers to the rear
of the unit and add green coal in front. NEVER load
over height of firebrick. This can result in damage to
your furnace and home.
4. Close by-pass damper.
 Too much draft air will cause clinkering of coal and will
waste heat up the chimney. Shut draft down to as low
a point as you can and still heat your home.
1. NOTE: Never stand in front of loading door when
opening it. Stand to the side.
2. NEVER completely cover the live fire with fresh coal.
Always leave a generous area of glowing coal at the
top of the fire and at the rear.
3. Always keep the ash pit clean.
