APPLICATION
The perlormance of a heating or cooling system depends
lirst of all on the quality of the equipment; secondly,
on the design of the distribution and return air slstem;
and last but not least. the workmanship
Lrsed
in installing
thc s1'51sm.
The best of equipment, r.r'hen improperly installed, will
not deliver satisfactory performance to the customer.
When the application ol' heating equipment or cooling
equipment is to be made, the procedure to use
selection and application is as follows:
L Calculate the heating or cooling load.
2. Sclect equipment.
3. Double check equipment blower capacities.

To insure correct systcm sizing, a survev should
-fhe heat
made of the structure to be air conditioned'
loss and heat gain should be calculated in accordunce
with the procedure contained in the Natitlnal Warm Air
Heating and Air Conditioning Association Manual J.
COMPLY WITH LOCAI, CODES
The installer should familiarize himself with and comply with all local codes and regulations which govern
the installation ol this t1,pe eqLripment. Local codes and
regulations take precedent over any recommendatior.rs
contained in these instructions.
ln lieu of Local Codes, the ecluipment should be installed
in accordance with the National Electrical Code, and
in accordance with the rccommendations made b1' the
National Board of Fire Underwriters.
CHECK ELECTRICAL POWER SUPPLY
The electrical power supply should be checked to'determine if adequate power is available, and near constant
voltage can be maintained. lf there is any question concerning the power supply, contact the local power company for corrections; otherwise, unsatisfactory performance may result.
ROOF JACK
close inspection ol the cut-a-way drawing of the roof
jack and furnace shown in Figure 1, will show that both
the flue pipe and the combustion air tube must be
securely attached to the furnace. This is to insure a
complete circuit for the combustion air and flue gases.
The .f urnac'e will nol operate unless the roo/ jat'k has
A
been
properlf installed.

APPLICATION
The telescoping flue pipe must be firmly seated on the
furnace flue collar and secured with a sheet metal
screw. The telescoping combustion air tube should be
pulled down and sealed against the top of the air chamber
located inside the
top of the furnace. The
straps,
attached to the combustion air tube. should be secured
to the top of the furnace with sheet metal screws. Sheet
metal screws should not be longer than % inch.
Problems assoc'ialecl u'ith intproper roo./ jack

Problem: The main burner comes on normally.
Main burner flame and pilot flame begins to lift
immediately, and floats to the top of the heat exchanger then goes out.
Cause: This is an indication that:
L The inner flue tube is missing or has not
been securely sealed to the flue outlet of the
furnace,
2. blocked flue.
This results in a recirculation of flue gases and
extinction of main burner and pilot.

INSTALLATION INSTRUCTIONS
GAS PIPING
Route the gas piping or tubing to the furnace. Use th"
black iron pipe or %" O.D. copper tubing If the piping
length exceeds 40', use 't7^" black iron pipe or '/a" copper
tubing.
When using natural gas, branch tubing may be copper
internally tinned or copper tubing containing not more
than 75 percent copper. When using L.P. gas, tubing
may be type K. Be sure to check local authorities for
any other requirements concerning gas piping. It is
recommended that a main shut-off valve be located in
the gas supply line external to the furnace. This shutoff valve is required by AGA as well as some local
codes.
When making the connection at the gas control valve,
use a wrench on the inlet side to prevent twisting the
valve body which could result in service problems.
After connections have been made, be sure all joints
are checked with soap suds to detect any leaks. This
should also include a check of the furnace controls
and piping. NEVER CHECK FOR LEAKS WITH
A LIGHTED MATCH.
CAUTION: DO NOT TEST THE FUEL SYSTEM AT
MORE THAN 14 INCHES WATER COLUMN AFTER
FURNACE HAS BEEN CONNECTED TO FUEL LINE.
ANY TEST CONDUCTED ABOVE 14 INCHES WATER
COLUMN MAY DAMAGE THE FURNACE CONTROL
2. Make sure all piping and tubing is free of foreign
matter. Apply thread seal to male threads only.
t7r" pilot tubing bween valve and pilot
burner assembly. Pilot burner assembly m ust be
mounted rigidly in a position where pilot will ignite
main burner when it has been reduced to smallest
flame which will hold thermomagnet safety' valve open.
4. t/,s" external vent connection is located at outlet end
of valve. Connect one end of vent tube to fitting on
valve and position other end near, . but not in, pilot
flame. Main burner flame must not impinge on gen3. Connect
erator cartridge or vent tube.
5. Make sure all wiring connections are clean and tight.
Screw thermocouple bushing in fingertight, plus I
turn. with small wrench. DO NOT OVERTIGHTEN.
6. Refer to information furnished with furnace for
proper heat anticipator sctting.

PILOT ADJUSTMENT
The pitot flame should be adjusted to bathe the end of
the pilot thermocouple with approximately t/r" of f)ame.
The pilot flame should appear blue on natural gas, and
blue with yellow tips if operating on L.P. gas. Remove
the pilot adjusting screw cover cap from the control
valve and adjust the underlying screw to obtain the
proper pilot flame. Replace the cover cap in the control
valve.
GAS CONVERSION INSTRUCTIONS
The PRESIDENTIAL series furnaces are equipped
to burn either natural gas or [-P gas. By using the
proper orifice and adjusting the pressure regulator
and pilot, the furnace can be converted to burn either
gas.
For LP gas, an LP gas identification tag should be
wired to the burner manifold, the orilice in the burner
should be marked "t-P," and the pressure converter
should be adjusted to the "LP" position.
For natural gas, a Natural gas identification tag should
be wired to the burner manifold, the orifice in the
burner should be marked "NAT," and the pressure
converter should be adjusted to the "NAT" position.
The extra orifice and gas identification tag are in the
cloth bag attached to the pilot line.
CONVERSION FROM NATURAL TO LP GAS

THE 7660-528 BURNER
The 1660-528 burner is a mono-port type burner with
a stainless steel flame spreader mounted above the
burner port to spread the flame out nearer the walls
of the heat exchanger. Just inside the burner port is
a flame retainer that holds a portion of the gas flame
down around the burner port.
The flame should be slightly yellow while the furnace
is operating. The burner flame should not rumble or
roar like a blow torch (furnace receiving too much
combustion air). The air shutter adjustment may be
pushed in to provide more primary air and pulled out
to reduce the amount of primarl' air being delivered
to the burner flamc. This adjustment depends upon the
average winter temperature and thc geographical location of the furnace.

AIR REQUIREMENTS
The proper operation of any Mobile Home furnace is
dependent upon satisfying the requirements for four
types of air.
l.
As seen in the cut-a-way vlew
Comhustion air
of the PRESIDENTIAL furnace, combustion air is
supplied to the burner through the roof jack. Down the
back of the furnace to an area below the combustion
chamber. Primary air for combustion is drawn into'
the venturi of the burner by the action of gas velocity
(aspiration) in the venturi. This air and gas mixture
is thoroughly mixed in the mixing chamber and
discharged upward against the flame spreader where
it is ignited by the pilot.
Combustion is completed with the addition of secon-
dary air around the outside
of the burner into
the
combustion chamber.
The hot products of combustion then rise in the heat
exchanger and pass to the outside through the flue
and roof jack. All combustion air is taken from the
outside resulting in a system referred to as sealed
combustion. See Figure 8 .

the moisture problem may be so bad that condensation may cause water spotted walls or ruined paint
jobs. When the air is warrn, the moisture in the
coach is invisible. Since warm air can hold more
moisture than cold air, air containing too much
water vapor condenses to form frost or water whenever it comes in contact with a cold surface. One of
the most common illustrations of visible condensation in the coach is the formation of water or frost
on the windows.
Cooking, washing, bathing, etc., all add moisture to
the air, and large amounts show up as condensation.
The small rectangular chute on the bottom of the
furnace brings in fresh air to the circulating blower.
The fresh air which is brought into the circulating
blower is then distributed as warm air through the
duct system. This cool outside air, after
being
warmed, is capable of absorbing moisture, thus
helping to reduce condensation.

4 Return
The Presidential furnaces are designed to
give
superior air-handling capabilities. This results in an
air temperature rise of 165'F. compared to the
200'F. rise that the Solar Paks were designed for.
lf you use less than 200 square inches free area
return grille you are reducing the air flow across the
heat exchanger and just asking for service problems
resulting in high temperature cycling on heating.
To avoid operational problems on the 7660 furnace,
the 7660-5491 return air grille must be used. This
grille has 200 square inches of free area and the use
of less free area can result in operational problems.

FAN SWITCHES
'I'he furnace is equipped with one fan switch located
at the top of the control panel. This switch is a normally open switch that closes with a rise in temperature. The fan switch is a disc type switch that is
calibrated to close at 105', and open at 90o.
As in the case ol a limit switch, the temperature on the
fan switch does not necessarily mean that the air will
be the same temperature. A fan switch, due to its location on the furnace, might actually start the blower at
an outlet air temperature that is above the calibrated
temperature.

The lower limit switch is located at the bottom of the

in this region are restricted ducts, too many floor
registers closed, or restricted inlet, i.e. dirty filter,
clothes hanging near or over the inlet area.
The lower limit will automatically reset when the air
temperature has cooled down.
The disk thermoswitch is operated by the heating and
cooling of a bi-metal disk. Under "hot" conditions,
the bi-metal disk will snap inward thrusting the electrical contacts open; thereby breaking the electrical
circuit. Upon cooling, the bi-metal disk will snap back
out and let the contacts close which will then let electrical power pass through without interruption.

THERMOSTATS
ANTICIPATION
The operation of a low voltage thermostat based solely
on mechanical means, generally results in wide variations in temperature in the conditioned area whether the
application is for heating or cooling. To insure a more
precise control of area temperature, low voltage thermostats contain heating and cooling anticipators.
In addition to improved room temperature control, heat
anticipation contributes to better air circulation. The
burner may cycle on and off several times during one
cycle of the fan. Since heat anticipators are powered
and effective only during the heating cycle, they are
placed in series with the control contacts. When the
contacts are closed, power is supplied to the heat
anticipator resistor.
MANUAL SWITCHING OPERATIONS
Generally, a sub-base used to control both heating and
cooling equipment will contain two switches, one
marked "FAN" and one marked "SYSTEM."

CAL/TION: Care should always be taken in the alignment of the thermostat attaching screws, as they may
also serve as terminal connectors. If threads are
stripped, a poor electrical connection will result.
INSTALLATION AND SERVICE
l. A low voltage thermostat is a precision instrument and should be treated as one. Care must be
used to insure a level installation with thermostats
using mercury bulbs.
2. Mount on a solid wall.
3. Locate the thermostat on an inside wall four to
five feet above the floor in an area free from drafts
and direct sunlight. Do not locate where directly
affected by lamps, fireplaces, appliances, or on walls
containing hot or cold pipes, ducts, chimneys.
4. Be sure anticipator matches or is adjusted to
match current (amp) draw of equipment being
Insufficient heat anticipation in a heating system results
in the bi-metal lagging behind the room temperature
change. This will cause longer "on" and longer "ofl'
periods with
a resultant larger room
temperature
varlatlon.
A common heating valve current draw is 0.4 amps,
and this should be matched on any adjustable anticipator. If the adjustable anticipator is set appreciably
higher, for example rJ.1 amps, it will increase the
room temperature variations by 3oF. or 4oF. and cause
longer running cycles.
For longer "on" periods, set the heat anticipation adjustment pointer at slightly higher amp value. For
shorter "on" periods, set the pointer at slightly lower
amp value. Move only t/q to /z scale division at a time.
(Never set the pointer at more than I % scale divisions
below the amp rating of the valve or relay current
rating.)
The anticipation function in a cooling thermostat is the
reverse of its heating application. The cooling anticipator is powered during the "ofl' cycle. As the room
temperature increases, heat is applied to the bi-metal
for the bi-metal to close
the contacts. Excessive cool anticipator temperature
decreasing the time necessary
results in shorter "offl' periods, consequently, more
frequent cycling of the cooling equipment. Insufficient
anticipation in a cooling thermostat causes long "ofl'
and
cycles resulting
in larger
temperature
variations in the room.

7 660A6901, 7 660-6931, 7 660-6921
Air Conditioning Blower Pockoges
APPLICATION
The Coleman 7660A6901 blower, equipped with 4 speed
blower motor; 7660-6931 blower, equipped with 3 speed
blower,motot;and766O4921 blower, equipped with 2 speed
blower motor are for use on all 7600 series Presidential Gas
Furnaces. The 7660A6901 can be set at low, medium, or
high speeds to match from 2 to 3% tons of air conditioning.
The766O493l can be set at low or high speeds to match2
to 3t/z tons of air conditioning. The 766O4921 goes to one
air conditioning speed automatically, to match 2 ot 2% tons
of air conditioning.
The 7600-700 series Presidential Gas Furnaces contain a 20
V.A. transformer. A 20 V.A. transformer is not large enough
to energize the contactor in an air conditioning condensing
unit. Coleman Mobile Home Condensing Units have been
produced both with and without their own transformer. If
you are adding air conditioning to a 7600-700 series furnace,
the condensing unit must contain a transformer. In the event
that there is no transformer in the condensing unit, one must
be ordered (pln 62723a5 l) and installed. The various wiring
hook-ups may be found below under "Wiring."
The 7600400 series Presidential Gas Furnaces have 40 V.A.
transformers factory installed. This series furnace was designed to accommodate addon air conditioners with no
transformer in the condensing units. If adding a condensing
unit to this series furnace, and the condensing unit does have
a transformer, it must be disconnected and removed. For
correct wiring procedures, see the "Wiring" section below.
