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. in the CALCULATINC THE SYSTEM LOAD bc 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. Figure 1 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 installation. 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. Solution: l. Replace inner flue tube, flue tube to the flue outlet of the 2. Secure the 3. furnace, Remove block. CUTA.WAY OF THE Problem: Pilot outage. Cause: Combustion air tube not installed or not sealed against the top of the air chamber located inside the top of the furnace. 7660-7101 ROOF JACK Reason: pressure zone. Downdraft will extinguish pilot. 2. Drawing combustion air from inside the home. Defeats the purpose of sealed combustion. l.

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.

Use a Phillips head screwdriver or similar blunt ended object to press spring down until you hear or feel it snap in place. Replace convertible regulator cap with "NAT CAS" marking in up position. INSTALLATION INSTRUCTIONS 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 l. Be sure gas and electricity to appliance is shut off. 4. Reverse valve regulator pressure converter to read Nat. Gas. See See Fig. 5 5. Push orilice holder back in place and replace the valve u'ith the two screws previously removed. Connect pilot feed tube to valve. Be sure all connections are tight. 6. Wire Natural gas idcntification tag to pilot line. 7. Store replaced orifice and LP gas identil'ication tag in cloth bag and attach to pilot line. 8. Use pilot adjusting screw to adjust pilot flame. Sce pilot adjustment. 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. 2. Disconnect pilot fecd tube from valve. 3. Remove the two screws holding valve to valve bracket and pull valve with orifice holder back and out of burner support exposing the orifice. Change to burner orifice marked LP. found in the cloth bag attached to the pilot line. 4. Reverse valve regulator pressure converter to read LP Gas. See Fig. 6. 5.

This is to give greater protection against burnout from continuous contact with the burner flame. Located in the top area ol the heat exchanger is a stainless steel baffle deflector to keep the direct upflow of heat from coming into immcdiate contact with the top of the heat exchanger. lt also slows the rising heat down before it escapes up the l-lue.

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 . Figure 8. l3 INSTALLATION INSTRUCTIONS Warm air is distributed through 2. Cirt'ulating air the duct system -by the circulating blower located at the top of the furnace. The operation of the blower is controlled by the fan switch which senses the heat inside the furnace. This is an automatic switch, located inside the control panel. 3. Fresh air coaches, due to location, may - Somemoisture problem. ln some cases have an excessive 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. air The louvers on the top front of the return air. Return air must be proadmit furnace vided back to the circulating blower in order to provide air distribution. Do not enclose the lurnace or otherwise obstruct these louvers. To 'do so will cause the furnace to limit and go to pilot. 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. t4 I I tl. Figure 9. INSTALLATION INSTRUCTIONS 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. to indicate the temwill open or close The disc switches used are marked perature at which the switch ELECTRICAL MOVEAELE CONTACT BI.METAL DISC..

An overheating condition could exist at the top of the furnace because of circulating Each furnace is equipped with two blower failure. electrical failure, or overfiring of the furnace. The lower limit shuts the lurnace olf in case of excessive heat build up in the lower portion ol the furnace' The lower limit switch is located at the bottom of the control wiring box. Some common causes of overheating 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. l5 THERMOSTATS Shown below are the two thermostats used with the PRESIDENTIAL gas furnace. Figure l0 shows the Camstat TlTH-180N heating only thermostat. Figure ll shows the Camstat CB35-E-lF sub-base which contains the cooling thermostat.

Camstat Cooling Sub-Base l6 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." FAN SWITCH ON Constant fan. The fan will run continuously re- gardless of the thermostat demand. AUTO The fan runs only as required by the system operatlon. SYSTEM SWITCH only, operates in response HEAT - Heating system to the thermostat. OFF Heating system and cooling system both off. Cooling system only, operates in response to COOL - the thermostat. 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. ANTICIPATION PROBLEMS HEATING SETTING TOO LOW l. Excess anticipation "on" cycles too short. 2. Rapid cycling. 3. Small temperature swings from the setting with a tendency to drop. SETTING TOO HIGH cycles too long. l.

During periods when the system is running close to its full capacity, more of the heat sensed by the bi-metal is from the anticipator than from room air; and the controlled area temperature will progressively decrease. 5.

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.
