The only combustible material allowed is wood.
• Exposure to contaminated combustion air will result in safety and performance-related problems. Do not install the furnace where the combustion air is exposed to the following substances: chlorinated waxes or cleaners chlorine-based swimming pool chemicals water softening chemicals deicing salts or chemicals carbon tetrachloride halogen type refrigerants cleaning solutions (such as perchloroethylene) printing inks paint removers varnishes hydrochloric acid cements and glues antistatic fabric softeners for clothes dryers and masonry acid washing materials
• If the furnace is used in connection with a cooling unit, install the furnace upstream or in parallel with the
7
cooling unit coil. Premature heat exchanger failure will result if the cooling unit coil is placed ahead of the furnace.
For vertical (upflow or downflow) applications, the minimum cooling coil width shall not be less than furnace width minus 1”. Additionally, a coil installed above an upflow furnace or under a counterflow furnace may be the same width as the furnace or may be one size larger than the furnace. Example: a “C” width coil may be installed with a “B” width furnace.
For upflow applications, the front of the coil and furnace must face the same direction.
• If the furnace is installed in a residential garage, position the furnace so that the burners and ignition source are located not less than 18 inches (457 mm) above the floor.
Protect the furnace from physical damage by vehicles.
• If the furnace is installed horizontally, the furnace access doors must be vertical so that the burners fire horizontally into the heat exchanger. Do not install the unit with the access doors on the “up/top” or “down/bottom” side of the furnace.
• Do not connect this furnace to a chimney flue that serves a separate appliance designed to burn solid fuel.
• For counterflow installations, the air conditioning coil must be downstream from the heat exchanger of the furnace.
• Counterflow installation over a noncombustible floor.
Before setting the furnace over the plenum opening, ensure the surface around the opening is smooth and level. A tight seal should be made between the furnace base and floor by using a silicon rubber caulking compound or cement grout.
• Counterflow installation over a combustible floor. If installation over a combustible floor becomes necessary, use an accessory subbase (see Specification Sheet applicable to your model for details). A special accessory subbase must be used for upright counterflow unit installations over any combustible material including wood. Follow the instructions with the subbase for proper installations. Do not install the furnace directly on carpeting, tile, or other combustible material other than wood flooring. ( NOTE : The subbase will not be required if an air conditioning coil is installed between the supply air opening on the furnace and the floor.

NOTE: When an existing furnace is removed from a venting system serving other appliances, the venting system may be too large to properly vent the remaining attached appliances.
The following vent testing procedure is reproduced from the
American National Standard/National Standard of Canada for
Gas-Fired Central Furnaces ANSI Z21.47-Latest Edition, CSA-2.3-
Latest Edition Section 1.23.1.
The following steps shall be followed with each appliance connected to the venting system placed in operation, while any other appliances connected to the venting system are not in operation: a.
Seal any unused openings in the venting system; b.
Inspect the venting system for proper size and horizontal pitch, as required by the National Fuel Gas
Code, ANSI Z223.1 or the CAN/CSA B149 Installation
Codes and these instructions. Determine that there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition; c.
In so far as practical, close all building doors and windows and all doors between the space in which the appliance(s) connected to the venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they shall operate at maximum speed. Do not operate a summer exhaust fan.
Close fireplace dampers;
d.
Follow the lighting instructions. Place the appliance being inspected in operation. Adjust thermostat so appliance shall operate continuously; e.
Test for draft hood equipped appliance spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle; f.
After it has been determined that each appliance connected to the venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their previous conditions of use; g.
If improper venting is observed during any of the above tests, the common venting system must be corrected.
House depressurization can cause back drafting or improper combustion of gas-fired appliances, thereby exposing building occupants to gas combustion products that could include carbon monoxide.
If this furnace is to be installed in the same space with other gas appliances, such as a water heater, ensure there is an adequate supply of combustion and ventilation air for all appliances. Refer to the latest edition of the National Fuel Gas Code NFPA 54/ANSI
Z223.1 or CAN/CSA B149 Installation Codes or applicable provisions of the local building codes for determining the combustion air requirements for the appliances.
Corrections must be in accordance with the latest edition of the
National Fuel Gas Code NFPA 54/ANSI Z223.1 and/or CAN/CSA
B149 Installation Codes.
This furnace must use indoor air for combustion. It cannot be installed as a direct vent (i.e., sealed combustion) furnace.
Most homes will require outside air be supplied to the furnace area by means of ventilation grilles or ducts connecting directly to the outdoors or spaces open to the outdoors such as attics or crawl spaces.
If resizing is required on any portion of the venting system, use the appropriate table in the latest edition of the National Fuel
Gas Code ANSI Z223.1 and/or CAN/CSA B149 Installation Codes.

Improved construction and additional insulation in buildings have reduced heat loss by reducing air infiltration and escape around doors and windows. These changes have helped in reducing heating/cooling costs but have created a problem supplying combustion and ventilation air for gas fired and other fuel burning appliances. Appliances that pull air out of the house (clothes dryers, exhaust fans, fireplaces, etc.) increase the problem by starving appliances for air.

Category I Venting is venting at a non-positive pressure. A furnace vented as Category I is considered a fan-assisted appliance and the vent system does not have to be “gas tight.” NOTE: Single stage gas furnaces with induced draft blowers draw products of combustion through a heat exchanger allowing, in some instances, common venting with natural draft appliances (i.e. water heaters). All installations must be vented in accordance with National
Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition. In Canada, the furnaces must be vented in accordance with the National Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and amendments.

An exterior masonry chimney is defined as a “Masonry” chimney exposed to the outdoors on one or more sides below the roof line.” The ability to use a clay lined masonry chimney depends on a parameter not associated with interior chimneys. This variable is the geographic location of the installation. Researchers have discovered that the winter design temperatures have a direct impact on the suitability of this type of venting. In most situations, the existing masonry chimneys will require a properly sized metallic liner.

A masonry chimney used as a vent for gas fired equipment must extend at least three feet above the highest point where it passes through the roof. It must extend at least two feet higher than any portion of a building within a horizontal distance of 10 feet. In addition, the chimney must terminate at least 3 feet above any forced air inlet located within 10 feet. The chimney must extend at least five feet above the highest connected equipment draft hood outlet or flue collar.
If the chimney does not meet these termination requirements, but all other requirements in the checklist can be met, it may be possible for a mason to extend the chimney. If this will not be practical, see Fix 1.

NY SOLID OR LIQUID FUEL APPLIANCES VENTED INTO THIS
CHIMNEY CHANNEL
Solid fuel appliances include fireplaces, wood stoves, coal furnaces, and incinerators.
Liquid fuel appliances include oil furnaces, oil-fired boilers and oil-fired water heaters.
Appliances which burn propane (sometimes referred to as LP (liquefied petroleum)) gas are considered gas-fired appliances.
Next, gently tap the inside of the liner with a Phillips screwdriver.
If the screwdriver perforates the liner, or if the tapping does not sound like metal hitting metal, the liner must be removed and replaced (Fix 4).
Remember that all appliances must be vented inside the liner.
Venting one appliance inside the liner and another appliance outside the liner is not acceptable.
Next, use a flashlight and small mirror to sight up the liner. B vent must be supported so as to not come into direct contact with the chimney walls or tile liner. If it is not, it can probably be rehung so as to be acceptable. A thimble or fire stop may be helpful here.
13
Flexible liners should be hung straight or nearly straight. If it is spiraled in the chimney and in good condition, it should be rehung.
To do this, break the top seal; pull up and cut off the excess liner length, and refit the top seal. Use caution when doing this, as the cut edges of flexible liners may be sharp.
• Masonry chimneys with no air gap between the liner and the bricks. (In practice, this can be difficult to detect.)
• Exterior chimneys (The tables in National Fuel Gas Code
NFPA 54/ANSI Z223.1 - latest edition and in the National
Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2
- latest editions and amendments assume interior chimneys.)
The surfaces of the liner must be physically sound. If gaps or holes are present, the metal liner must be removed and replaced (Fix 4).
Finally, confirm that the metal liner is the correct size for the appliances to be installed. Use the GAMA tables and rules.
If a metal liner is not present, a clay tile liner must be present, or the chimney must be lined (Fix 4).
If, in the judgment of the local gas utility, installer, and/or local codes; one or more of the above factors is likely to present a problem, the chimney must be relined (Fix 4).

• Tile sections missing
• Gaps between tile sections
• Signs of condensate drainage at the cleanout or vent connectors
• Mortar protruding from between tile sections
• Use of sewer pipe or drainage pipe rather than an approved fire clay tile reline the chimney (Fix 4).
Next, measure the size of the liner. It may be possible to do this from the cleanout. The liner must be at least as large as the minimum size established by the tables in National Fuel Gas Code
NFPA 54/ANSI Z223.1 - latest edition and in the National Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and amendments. If the liner is too small or too large, then the chimney must be relined (Fix 4).

RRANGEMENTS
If the masonry chimney has more than one channel, it may be possible to vent the gas appliances into one channel and vent the solid or liquid fuel appliance(s) into another channel(s). Do not vent an 80+ Furnace inside of a metal liner with other appliances vented outside the liner.
Alternatively, the homeowner may agree to discontinue use of the fireplace (solid fuel appliance). If so, the tile liner must be cleaned to remove creosote buildup. The fireplace opening must then be permanently sealed.
If oil-fired appliance(s) are being replaced by gas-fired appliance(s), the tile liner must first be cleaned to remove the fuel oil residue.
If gas-fired appliances are to be vented into a clay tile liner, a source of dilution air is required.
Dilution air cannot be obtained through:
• Induced draft appliances
• Natural draft appliances with vent dampers
If none of the above options is practical, the furnace may need to be vented vertically with a B Vent.
Sufficient dilution air can ordinarily be obtained through the draft hood of a natural draft appliance only if the appliance’s vent connector does not include a vent damper. If dilution air will not be available, the chimney must be relined (Fix 4).

• Extremely cold weather
• Long vent connectors
Under some conditions, a 90%+ furnace could be installed rather than an 80% furnace. The 90%+ furnace can be vented horizontally or vertically through PVC pipe.

ELINING
Relining options include B vent and flexible liners.
If the chimney has diagonal offsets, B vent probably cannot be used.
14
If B vent is to be used, it must be supported adequately. Supports
(such as fire stops or thimbles) must be used to prevent the B vent from coming into direct contact with the tile liner or chimney walls. Direct contact would result in higher heat loss, with an increased possibility of poor venting system performance.
It is not acceptable to vent one appliance inside the B vent and other appliances outside. The excess space between the B vent and the chimney walls must be covered at the top of the chimney by a weatherproof, corrosion resistant flashing.
The B vent should then be topped with a listed vent cap. The listed vent cap will, when installed per the manufacturer’s instructions, prevent problems due to rain, birds, or wind effects.
• It is required by your local building codes.
Even if none of those three conditions exist which require additional liner insulation, the installer may wish to consider it if:
• The local climate is very cold.
• The chimney is very tall.
• The vent connectors used are very long or have a large number of elbows.
• Local experience indicates that flexible liners installed without insulation are likely to have condensation problems.
A B-vent installed as described in this section is considered to be an enclosed vent system, and the sizing tables in National Fuel
Gas Code NFPA 54/ANSI Z223.1 - latest edition and in the National
Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and amendments may be used.
Insulation must be selected and installed in accordance with the liner manufacturer’s instructions.
Finally, cap the chimney and terminate the liner in accordance with the liner manufacturer’s instructions.

ONNECTIONS
If a flexible liner is to be used, it must be made of the proper materials:
• For most residential applications, an aluminum liner should be acceptable.
• If the combustion air supplied to the furnace will be contaminated with compounds containing chlorine or fluorine, a liner of AL 29-4C stainless steel should be used. Common sources of chlorine and fluorine compounds include indoor swimming pools and chlorine bleaches, paint strippers, adhesives, paints, varnishes, sealers, waxes (which are not yet dried) and solvents used during construction and remodeling. Various commercial and industrial processes may also be sources of chlorine/fluorine compounds.
• Heavier gauge 300 and 400 series stainless steel liners were developed for use with oil or solid fuel appliances.
They are not suitable for use with gas-fired appliances.
Flexible liners specifically intended and tested for gas applications are listed in the UL “Gas and Oil Equipment
Directory”. (UL Standard 1777).

/
TANK TO THE FURNACE
.
When sizing gas lines, be sure to include all appliances which will operate simultaneously.
The gas piping supplying the furnace must be properly sized based on the gas flow required, specific gravity of the gas, and length of the run. The gas line installation must comply with local codes, or in their absence, with the latest edition of the National Fuel
Gas Code, NFPA 54/ANSI Z223.1.
To connect the furnace to the building’s gas piping, the installer must supply a ground joint union, drip leg, manual shutoff valve, and line and fittings to connect to gas valve. In some cases, the installer may also need to supply a transition piece from 1/2" pipe to a larger pipe size.
The following stipulations apply when connecting gas piping.
• Use black iron or steel pipe and fittings for the building piping.
• Use pipe joint compound on male threads only. Pipe joint compound must be resistant to the action of the fuel used.
• Use ground joint unions.
• Install a drip leg to trap dirt and moisture before it can enter the gas valve. The drip leg must be a minimum of three inches long.
• Install a 1/8" NPT pipe plug fitting, accessible for test gage connection, immediately upstream of the gas supply connection to the furnace.
• Use two pipe wrenches when making connection to the gas valve to keep it from turning. The orientation of the gas valve on the manifold must be maintained as shipped from the factory.
• Install a manual shutoff valve between the gas meter and unit within six feet of the unit. If a union is installed, the union must be downstream of the manual shutoff valve, between the shutoff valve and the furnace.
• Tighten all joints securely.
• Connect the furnace to the building piping by one of the following methods:
–
Rigid metallic pipe and fittings.
–
Semi-rigid metallic tubing and metallic fittings.
Aluminum alloy tubing must not be used in exterior locations.
–
Use listed gas appliance connectors in accordance with their instructions. Connectors must be fully in the same room as the furnace.
–
Protect connectors and semi-rigid tubing against physical and thermal damage when installed. Ensure
19
aluminum-alloy tubing and connectors are coated to protect against external corrosion when in contact with masonry, plaster, or insulation, or subjected to repeated wetting by liquids such as water (except rain water), detergents, or sewage.

A gas detecting warning system is the only reliable way to detect a propane gas leak. Rust can reduce the level of odorant in propane gas. Do not rely on your sense of smell. Contact a local propane gas supplier about installing a gas detecting warning system. If the presence of gas is suspected, follow the instructions in the
Safety Considerations section of this manual.
All propane gas equipment must conform to the safety standards of the National Board of Fire Underwriters, NBFU Manual 58.
For satisfactory operation, propane gas pressure must be 10 inch
WC at the furnace manifold with all gas appliances in operation.
Maintaining proper gas pressure depends on three main factors:
1. Vaporization rate, depending on temperature of the liquid, and “wetted surface” area of the container or containers.
2. Proper pressure regulation. (Two-stage regulation is recommended for both cost and efficiency).
3. Pressure drop in lines between regulators, and between second stage regulator and the appliance. Pipe size will depend on length of pipe run and total load of all appliances.

Filters must be used with this furnace. Discuss filter maintenance with the building owner. Filters do not ship with this furnace, but must be provided by the installer. Filters must comply with
UL900 or CAN/ULCS111 standards. Damage or repairs due to failure to install filters in the furnace are not covered under the warranty.
NOTE: An undersized opening will cause reduced airflow.
A closed return duct system must be used, with the return duct connected to the furnace. NOTE: Ductwork must never be attached to the back of the furnace. For installations requiring more than
1800 CFM, use a bottom return or two sided return. Supply and return connections to the furnace may be made with flexible joints to reduce noise transmission. To prevent the blower from interfering with combustion air or draft when a central return is used, a connecting duct must be installed between the unit and the utility room wall. Furnace is shipped with the top flanges in the flat position. Before installing a coil or ducts, the flanges must be bent 90°. A room, closet, or alcove must not be used as a return air chamber.
U
Depending on the installation and/or customer preference, differing filter arrangements can be applied. Filters can be installed in the central return register or a side panel external filter rack kit
(upflows), or the ductwork above a downflow furnace. As an alternative, a media air filter or electronic air cleaner can be used as the primary filter.

When the furnace is used in connection with a cooling unit, the furnace should be installed in parallel with or on the upstream side of the cooling unit to avoid condensation in the heating element. With a parallel flow arrangement, the dampers or other means used to control the flow of air must be adequate to prevent chilled air from entering the furnace and, if manually operated, must be equipped with means to prevent operation of either unit unless the damper is in the full heat or cool position.
Damper must be in open position when appliance main burner(s) is operating.
Le registre doit être ouvert lorsque tout brûleur principal de l’appareil est en état de fonctionnement.
One of the most common causes of a problem in a forced air heating system is a blocked or dirty filter. Circulating air filters must be inspected monthly for dirt accumulation and replaced if necessary. Failure to maintain clean filters can cause premature heat exchanger failure.
A new home may require more frequent replacement until all construction dust and dirt is removed. Circulating air filters are to be installed in the return air duct external to the furnace cabinet.

When the furnace is installed without a cooling coil, it is recommended that a removable access panel be provided in the outlet air duct. This opening shall be accessible when the furnace is installed and shall be of such a size that the heat exchanger can be viewed for visual light inspection or such that a sampling probe can be inserted into the airstream. The access panel must be made to prevent air leaks when the furnace is in operation.
NOTE: In a horizontal installation the air conditioning coil must be adequately supported by proper brackets and supports.
Inadequate coil support can result in furnace cabinet distortion and air leakage.

Consider installing an air cleaner with deep-pleated media filter at the time of furnace installation. A deep-pleated filter with a MERV rating of 8 (minimum) will often provide better filtration to protect equipment and the air distribution system than a standard 1" filter and often has lower static pressure loss than a 1" filter. Also a deep-pleated filter will typically require less frequent replacement intervals. Avoid using highly restrictive 1" filters which produce static pressure loss greater than .25" W.C. In some installations the minimum filter size required (consult filter sizing chart) will not lend itself to a filter installation on the side of the furnace. The installation of a centrally installed air cleaner cabinet or a return duct filter installation may offer more practicality.
Clean Comfort™ brand MERV 11 air cleaners have 5¼” media filters and are available in the following configurations. Consult your distributor for information on our complete line of IAQ Clean Comfort™ products.

The gas input rate to the furnace must never be greater than that specified on the unit rating plate. To measure natural gas input using the gas meter, use the following procedure.
1. Turn OFF the gas supply to all other gas-burning appliances except the furnace.
2. While the furnace is operating, time and record one complete revolution of the smallest gas meter dial.
3. Calculate the number of seconds per cubic foot (sec/ ft 3 ) of gas being delivered to the furnace. If the dial is a two cubic foot dial, divide the number of seconds recorded in step 2 by two.
4. Calculate the furnace input in BTUs per hour (BTU/ hr). Input equals the installation’s gas heating value multiplied by a conversion factor (hours to seconds), divided by the number of seconds per cubic foot. The measured input must not be greater than the input indicated on the unit rating plate.
EXAMPLE:
Installation’s gas heating (HTG) value: 1,000 BTU/ft 3
(Obtained from gas supplier)
Installation’s seconds per cubic foot: 34 sec/ ft 3
Conversion Factor (hours to seconds): 3600 sec/hr
Input = (Htg. value x 3600) ÷ seconds per cubic foot
Input = (1,000 BTU/ft 3 x 3600 sec/hr) ÷ 34 sec/ ft 3
Input = 106,000 BTU/hr
This measured input must not be greater than the input indicated on the unit rating plate.
5. Turn ON gas and relight appliances turned off in step 1.
Ensure all the appliances are functioning properly and that all pilot burners are operating.
1. Operate furnace with burners firing approximately 15 minutes. Ensure all registers are open and all duct dampers are in their final (fully or partially open) position.
2. Place thermometers in the return and supply ducts as close to the furnace as possible. Thermometers must not be influenced by radiant heat by being able to “see” the heat exchanger.
3. Subtract the return air temperature from the supply air temperature to determine the air temperature rise. Allow adequate time for thermometer readings to stabilize.
4. Adjust temperature rise by adjusting the circulator blower speed. Increase blower speed to reduce temperature rise.
Decrease blower speed to increase temperature rise. Refer to the following section for speed changing details.

The proper amount of temperature rise is usually obtained when the unit is operated at the rated input with the “as shipped” blower speed. If the correct amount of temperature rise is not obtained, it may be necessary to change the blower speed.
An incorrect temperature rise can cause condensing in or overheating of the heat exchanger. Determine and adjust the temperature rise as follows. The temperature rise must be within the range specified on the rating plate or Specification Sheet applicable to your model. (Please contact your distributor or our website for the applicable Specification Sheet referred to in this manual.)
Furnaces are equipped with either a PSC or EEM circulator blower motor. Either blower provides ease in adjusting blower speeds.
Refer to the Blower Performance Data in the back of the manual for proper selection of heating and cooling speeds. The cooling blower speed is shipped set on HIGH. The heat blower speed for
*(M,H,D)H8 / ADSS8 models is shipped on MEDIUM. For *(M,D)H8
/ ADSH8 models high heat ships on MEDIUM and low heat is shipped on MEDIUM-LO. For GME8 / AMEH8 models high heat ships on MEDIUM-HI (T4) and low heat is shipped on MEDIUM
(T3). These blower speeds should be adjusted by the installer to match the installation requirements so as to provide the correct heating temperature rise and the correct cooling CFM.
29
To adjust the circulator blower speed, proceed as follows:
1. Turn OFF power to the furnace.
2. Select the heating and cooling blower speeds that match the installation requirements from the airflow table in the
Specification Sheet applicable to your model. (Please contact your distributor or our website for the applicable
Specification Sheet referred to in this manual.)
3. Relocate desired motor leads to the circulator blower heat and cool speed terminals on the integrated control module.
(Terminals are identified as LO HEAT, HI HEAT and COOL
(hot)) for *(M,D)H8 / ADSH8, GME8 & AMEH8 models and
HEAT and COOL for *(M,H,D)S8 / ADSS8 models). If a heating speed and the cooling speed are the same, a jumper wire must be used between the heat and cool terminals.
4. Connect all unused blower motor leads to the “PARK” terminals on the integrated control module. Any leads not connected to the “PARK” terminals must be taped.
5. Turn ON power to furnace.
6. Verify proper temperature rise as outlined in Temperature
Rise section .
The time period is determined by the 2 nd Stg Dly DIP switch.
Setting the 2 nd Stg Dly DIP switch to 5 minutes fixes the delay period at 5 minutes. Setting the 2 nd Stg Dly DIP switch to Auto enables an algorithm that calculates a delay period based on the heating cycle time and the total cycle time. The delay period can range from 1 minute to 12 minutes.

NOTE: Items in this section refer to the air circulator blower fan in the *(M,D)H8 / ADSH8, GME8 & AMEH8 models, NOT to the induced draft blower. The induced draft blower timing sequence is not adjustable. The circulator blower fan timing is adjustable only on models with optional “heating fan OFF delay” adjustment pins or switches. It is NOT adjustable in any other circumstances.
As shipped, the circulator blower fan will remain on for 150 seconds after the gas valve closes. When a call for cooling occurs, the circulator fan comes on and remains on for 45 seconds after the call for cooling ends. During normal heating operation, the circulator fan will come on approximately 34 seconds after the gas valve opens.

Refer to your furnace rating plate for the maximum ESP (external duct static) rating.
Total external static refers to everything external to the furnace cabinet. Cooling coils, filters, ducts, grilles, registers must all be considered when reading your total external static pressure. The supply duct pressure must be read between the furnace and the cooling coil. This reading is usually taken by removing the “A” shaped block off plate from the end on the coil; drilling a test hole in it and reinstalling the block off plate. Take a duct static reading at the test hole. Tape up the test hole after your test is complete.
The negative pressure must be read between the filter and the furnace blower.
Too much external static pressure will result in insufficient air that can cause excessive temperature rise. This can cause limit switch tripping and heat exchanger failure.
To determine total external duct static pressure, proceed as follows;
1. With clean filters in the furnace, use a draft gauge (inclined manometer) to measure the static pressure of the return duct at the inlet of the furnace. (Negative Pressure)
2. Measure the static pressure of the supply duct. (Positive
Pressure)
3. The difference between the two numbers is .4” w.c.
Example: static reading from return duct = -.1" w.c.
static reading from supply duct = .3" w.c.
total external static pressure on this system = .4" w.c.
NOTE: Both readings may be taken simultaneously and read directly on the manometer if so desired. If an air conditioner coil or
Electronic Air Cleaner is used in conjunction with the furnace, the readings must also include theses components, as shown in the following drawing.
4. Consult proper tables for the quantity of air.
30
If the total external static pressure exceeds the maximum listed on the furnace rating plate, check for closed dampers, registers, undersized and/or oversized poorly laid out duct work.

The burner flames should be inspected with the burner compartment door installed. Flames should be stable, quiet, soft, and blue
(dust may cause orange tips but they must not be yellow). Flames should extend directly outward from the burners without curling, floating, or lifting off. Flames must not impinge on the sides of the heat exchanger firing tubes.
A number of safety circuits are employed to ensure safe and proper furnace operation. These circuits serve to control any potential safety hazards and serve as inputs in the monitoring and diagnosis of abnormal function. These circuits are continuously monitored during furnace operation by the integrated control module.

RECAUTIONS
NOTE: Discharge body’s static electricity before touching unit. An electrostatic discharge can adversely affect electrical components.
Use the following precautions during furnace installation and servicing to protect the integrated control module from damage. By putting the furnace, the control, and the person at the same electrostatic potential, these steps will help avoid exposing the integrated control module to electrostatic discharge. This procedure is applicable to both installed and uninstalled (ungrounded) furnaces.
1. Disconnect all power to the furnace. Do not touch the integrated control module or any wire connected to the control prior to discharging your body’s electrostatic charge to ground.
2. Firmly touch a clean, unpainted, metal surface of the furnace away from the control. Any tools held in a person’s hand during grounding will be discharged.
3. Service integrated control module or connecting wiring following the discharge process in step 2. Use caution not to recharge your body with static electricity; (i.e., do not move or shuffle your feet, do not touch ungrounded objects, etc.). If you come in contact with an ungrounded object, repeat step 2 before touching control or wires.
4. Discharge your body to ground before removing a new control from its container. Follow steps 1 through 3 if installing the control on a furnace. Return any old or new controls to their containers before touching any ungrounded object.

• All furnaces ship as high-speed cooling and medium-speed heating. Installer must adjust blower cooling and heating speed as needed.
• For most jobs, about 375 - 400 CFM per ton when cooling is desirable.
• INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE RATING PLATE.
• This chart is for information only. For satisfactory operation, external static pressure should not exceed value shown on the rating plate.
• A properly derated unit will have approximately the same temperature rise at a particular CFM, while ESP at the CFM will be lower.
• Temperature rise data is based on 2nd-stage heat. First-stage heat is 75% of rise indicated above.
