GENERAL INFORMATION

Read this manual carefully and in it’s entirety prior to performing any maintenance or service on

the burner.

WARRANTY

Wayne Combustion Systems warrants its burner’s specifically to organizations that have purchased it for resale, including your dealer. If you have a problem with your burner, or its installation, you should contact your dealer for assistance, for a full description of the warranty see page 39.

MAINTENANCE

Wayne Combustion Systems recommends yearly inspection/service of your oil heating system by a qualified service agency or individual.

A qualified service agency or individual must be:

 Licensed or certified to install and provide technical service to oil heating systems.  Experienced with all applicable codes, standards and ordinances.  Responsible for the correct installation and commission of the equipment.

 Skilled in the adjustment of oil burners using combustion test instruments

APPROVALS

This burner complies with ANSI/UL Standard 296 and is for use with No. 1 fuel oil or No. 2 fuel oil and is UL listed for use with Group I or Group II primary safety controls. The states of Massuchusetts, New York and local approvals are shown on the burner’s nameplate label. All burners must be installed in accordance with the National Fire Protection Association, and in complete accordance with all local codes and authorities having jurisdiction. Regulation of these authorities takes precedence over the general instructions provided in this manual.

MANUAL ORGANIZATION

This manual is organized so that the licensed contractor can troubleshoot the service issue with the burner by working through the GENERAL TROUBLESHOOTING GUIDE on page 7. The GENERAL TROUBLESHOOTING GUIDE is organized by the performance issue or “problem” requiring attention. Each problem will list potential root causes that may result in the problem listed in order from most likely to least likely, and the solution to correct each root cause that may be affecting burner performance. The solution listed for each root cause will reference supplemental information regarding normal burner/component operation and service instructions depending on the problem and root-cause. If this is a new installation see GENERAL INSTALLATION INFORMATION on page 20.

MODEL DIFFERENCES

The EHASR burner utilizes unique air cones and oil gun assemblies to optimize burner performance in its rated firing range. The air cone is a single piece construction and is fixed to the air tube. The oil gun depth is set in reference to the fixed air cone The EH and EHA have the flamelock attached to the nozzle adaptor on the oil gun, this allows the burner to have a variable gun depth setting based on the firing rate needed. An EHA burner is different from a EH because the EHA uses an oil pump that is rated up to 3 gal/hr, while the EH model will use a larger pump that is rated up to 7 gal/hr to attain the higher firing rates.

BURNER COMPONENTS

The EHASR, EHA, and EH model burners are constructed with components of varying design. For example, the ignition device may be an iron core transformer or a solid state igniter. Both devices perform the same function, and they use the same troubleshooting methodology. There are also two distinct types of motors utilized by these burners. The “Permanent

Split Capacitor” or PSC motors (silver in color) utilize a thermal protection device that automatically resets when the motor cools down. The “Split-Phase” motors (black jacket) utilize a manual reset thermal protector. Appliance or equipment

manufacturers may specify one type of component over another. Please contact Wayne Combustion Systems for assistance with replacement component selection.

TROUBLESHOOTING

PROBLEM

POSSIBLE CAUSE

SOLUTION

BURNER WILL NOT LIGHT

Little or no fuel

Fill tank with fuel.

Improper fuel or water in fuel

Drain fuel tank and fill with proper fuel.

Limit switch open

Close limit or thermostat switch, and check limit switch for proper cycling operation.

Improper electrode spacing, gap to small

Clean and position electrode tips according to Figure 14 or Figure 15 on pages 26-27.

Plugged fuel filter

Replace as needed.

Misadjusted burner air bands

Re-adjust air bands for clean burn.

Little or no fuel pressure from fuel pump

Increase fuel pressure to manufacturer's specifications. See Figure 25 on page 36 for pump features. Check that plastic coupler (see Figure 1 on page 13, item 10) is not slipping on pump shaft, replace as needed and/or replace pump.

Before troubleshooting, familiarize yourself with the startup procedures and sequence of operation. Check the burner, ignitor or transformer, oil primary control (if equipped), and cad cell (if equipped) for proper operation and condition.

The Honeywell R7284 oil primary control’s reset button is the “i” button, the R7184, R8184 and

Wayne control is the big red button. Pressing the reset button and restarting the burner more than once with the burner not lighting could cause oil buildup in the firing chamber. This will cause smoking and possible detonation that could damage the equipment if the burner does light

Preliminary Steps

Check the following common causes of issues:

 Wiring connections, fuses, power supply to the burner blower motor, controls, and ignition device.  Limit control is closed.  Thermostat (controller) is calling for heat.  Contacts between ignition device and electrodes.  Electrode gap is properly set at nozzle.  Oil piping to burner and tank is properly sized and is in good condition (see Oil Pipe Sizing Information on

page 37 ).

 Oil pump pressure.  Oil nozzle is correctly sized for application.  Check cad cell location and photo eye cleanliness.

SEQUENCE OF OPERATION: BURNERS WITH R7284G AND R8184G CONTROLS

BURNER OPERATION

On every call for heat the oil primary control performs an internal safety check which takes five seconds to complete. During these five seconds, the oil primary control verifies that the cad cell is outputting a “no flame” resistance value. After the check, the oil primary control will simultaneously energize the burner blower motor, solenoid valve (if equipped), and ignition device. The control will then enter the 15 second trial for ignition period; once flame is established the oil primary control will continue to monitor the flame by using the cad cell’s resistance value. The oil primary control allows burner operation to continue until the thermostat control’s “call for heat” is satisfied. Once the thermostat is satisfied the burner will be de-energized. If flame is not detected during the trial for ignition, the oil primary control will go into a “lock-out” condition. If this occurs, proceed to the section titled SAFETY LOCK-OUT TIME.

SAFETY LOCK-OUT TIME

Ignition failure occurs during the first “trial for ignition” period The cad cell monitors the combustion chamber for flame during the burner’s trial for ignition period. If no flame is detected

the oil primary control will go into a lockout condition. When the oil primary control goes into lockout it will de-energize the burner, and the control’s LED light will flash ½ sec on, and ½ sec off. Before attempting to start the burner again the control must be reset. Press and hold the “i” button for three seconds to reset the control. If normal ignition does not occur see GENERAL TROUBLESHOOTING GUIDE on page 7.

Intermittent flame failure occurs during a “call for heat”

If the oil primary control stops sensing a flame after the flame has been proven and the trial for ignition timer has expired, the oil primary control enters a limited recycle mode where it will de-energize the burner for one minute, while the LED light will flash for 2 seconds on, and 2 seconds off. After one minute the oil primary control resumes the call for heat, and enters another “trial for ignition” period. If a flame is proven during the trial for ignition, and lost after the trial for ignition timer expires the control will go into another recycle mode countdown. If no flame is proven during the trial for ignition period the control will go into a lockout condition. If the control tries three recycle modes where flame is proven, and then subsequently lost the control will go into a hard lockout condition de-energizing the burner. If normal ignition does not occur see GENERAL TROUBLESHOOTING GUIDE on page 7.

If normal ignition does not occur see GENERAL TROUBLESHOOTING GUIDE on page 7.

SEQUENCE OF OPERATION: BURNER WITHOUT CONTROL

Make sure combustion chamber is free of oil or oil vapor before starting system.

BURNER OPERATION

If the burner is controlled by a high voltage limit switch on the incoming power line to the burner, the operation of the burner is a simple ON/OFF mechanism, where all the burner components will be energized simultaneously to fire the burner. If any problems arise during ignition or continued operation of the burner see the GENERAL

TROUBLESHOOTING GUIDE on page 7.

CHECK SAFETY FEATURES

GENERAL INSTALLATION INFORMATION

Never exceed 3 PSI pressure to the suction side of the fuel pump. A pressure over 3 PSI

may cause damage to the shaft seal and allow it to leak oil.

Do not install by-pass plug if running single pipe operation, this will over-pressurize the pump

causing an oil leak at the pump shaft seal.

When installing the burner, be sure to provide adequate space for easy service and maintenance. Prior to installation of the oil burner, the heating system should be carefully inspected for defects and cleanliness. The flue passages and heat absorbing surfaces must be clean to ensure maximum heat transfer. Soot acts as an insulator, which retards the transfer of heat. The combustion chamber, flue gas passages, and all doors and openings must be tightly sealed to eliminate air infiltration. Excess air cools the flame and thus lowers efficiency. Inspect the flue and chimney for leaks and obstructions. Be sure the chimney is of adequate size and height. Install a draft regulator the same size as the flue pipe (see paragraph under DRAFT REGULATORS).

COMBUSTION CHAMBER

The purpose of a combustion chamber is to maintain a high flame temperature by reflecting the heat back into the flame. A high flame temperature assures greater combustion efficiency and lower stack losses. An insulating refractory or a Fiber Fax type chamber can be used with this burner. It is important to select and install, the correct nozzle size for a given combustion chamber size (see Table 4 on page 35). On all oil burners the atomized oil must not touch the sides or bottom of the combustion chamber or improper combustion will occur leading to smoke and soot build-up. To reduce smoke while the burner is running, the burner must have an adequate supply of combustion air by having a large enough opening on the air band assembly. If too much air is utilized it can lead to high gas exhaust temperatures, and lower combustion efficiency. Install the burner so the face of the air cone on the burner is set a ¼ inch behind the inside front wall of the chamber (see Figure 20 on page 30).

FUEL PUMPS

Model EHASR, EHA and EH oil burners are provided with single stage 3450 RPM fuel pumps with the by-pass plug removed for a single pipe installation. This is satisfactory where the fuel supply is on the same level, or above burner, permitting gravity flow of oil.

When it is necessary to lift the oil to the burner, a return line should be run between the fuel pump and oil tank. (If lift exceeds 10 feet, a two stage fuel pump must be used with a return line). When a two line installation is made, the by-pass plug must be installed. This is supplied with the burner attached to fuel pump, along with a pump data sheet in a plastic bag.

FUEL LINES

When oil lines are continuous runs, heavy wall copper tubing is recommended for the fuel lines. Be sure that all connections are absolutely air-tight. Check all connections and joints. Flared fittings are recommended. Do not use compression fittings. Avoid running tubing against the appliance and across ceiling or floor joist; if possible install under floor. Avoid using fittings in inaccessible locations. If possible, avoid running oil lines overhead. Specific information on piping, connections, lift capabilities and tank installations is provided in the instruction sheet of the fuel pump manufacturer, however if the instruction gets damaged or unreadable see oil pipe sizing information under reference information on page 37. Install an UL certified oil filter of adequate size for all installations.

FUEL TANKS

Label all wires prior to disconnection when servicing burners. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing

If any of the original burner wiring must be replaced, it must be replaced with #18 AWG 105°C wire or equivalent

Local codes and regulations must be followed regarding tank and burner installation. Check existing tanks for water and sludge accumulation; clean if necessary. Also clean or replace existing piping.

ELECTRICAL WIRING OF BURNER

The oil burner is shipped completely wired. It is only necessary to supply the line voltage circuit, thermostat and limit circuit. All wiring must comply with the National Electric Code or the code legally authorized in the locality where the installation is being made. The burner, when installed must be electrically grounded in accordance with local codes or, in absence of local codes, with the latest edition of the National Electrical Code, ANSI/NFPA No. 70. Refer to wiring diagrams Figure 3,Figure 4 and Figure 5 on pages 16 & 17 for reference on wiring, and thermostat connection. If an external electrical source is utilized, the oil burner, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the latest edition of the National Electrical Code, ANSI/NFPA No. 70.

For line voltage wiring to the burner use solid copper conductor wire not lighter than #14 AWG. If a fused disconnect is

used, it should be fused for a minimum of 20 amps.

If the oil burner comes equipped with an oil primary control, the burner will be shipped with a jumper wire on the thermostat (T-T) terminals. The jumper needs to be removed for remote thermostat control and the thermostat needs to be connected per wiring diagrams. A T-T terminal is an open/close switch for the oil primary control and no voltage should be connected to it. For boilers it may be necessary to leave the T-T terminal jumped as the aquastat may be providing the voltage to the burner and controlling when voltage is sent to the burner. The burner is controlled by the appliance. Once wiring is complete between burner and appliance, verify that the appliance is controlling the burner’s on/off operation.

When connecting the burner to the line voltage electrical supply, utilize the knockout provided on the burner’s junction

box.

CHIMNEY INSTALLATION

Follow the recommendations of the appliance manufacturer. A chimney shall be capable of producing a draft as recommended by the appliance manufacturer. It must be properly designed, of adequate size, be above the surrounding objects, tile-lined, with no obstructions, and be in a good state of repair. The smoke pipe should sit flush with the inside of the tile and be cemented in place. All cleanout doors should be sealed. A draft inducer may be used to overcome inadequate draft conditions. If a draft inducer is used, provisions must be made to ensure the burner does not operate if the draft inducer fails.

DRAFT REGULATORS

A draft regulator shall be provided unless otherwise specified by the appliance manufacturer. The draft regulator shall be installed in accordance with local codes and regulations or in the absence of local codes, with ANSI NFPA31. Refer to appliance manufacturer’s instructions for recommended over fire and stack draft.

AIR SUPPLY FOR COMBUSTION

Arrow Decal

Slot

cover

A burner shall not be installed in an area where normal air circulation or infiltration is limited and it restricts the amount of air necessary for proper combustion and venting. When the heating appliance is installed in a confined space, two permanent air openings shall be provided; one near the top of the enclosure and one near the bottom. Each opening shall have a free area of no less than one square inch per 1000 Btu/hr (140 square inch per gal/hr) of the total input rating of all the appliances in the space. When the house is of unusually tight construction, has a kitchen ventilating system, exhaust fans, clothes dryer or vented fireplaces, it is recommended that combustion air be supplied through two permanent openings. The openings should connect directly, or by means of ducts, with outdoors or to such spaces (attic or crawl) that are exposed to the outdoors. For additional information, refer to ANSI standard NFPA31.

NOZZLE AND AIR CONE SELECTION

The EHASR, EHA, and EH oil burners typically fire well with a solid or semi-solid nozzle with a spray angle of 80, 70, or 60 degrees. In most upgrading or conversion installations, the use of an 80 degree solid nozzle is a good starting point. Always use the proper nozzle size, spray cone type and spray angle the appliance manufacturer recommends. Should this information not be available, your own good judgment will prevail. Under no circumstances attempt to fire the EHA or EHASR oil burners under their 0.75 gal/hr minimum input rating or over their 3.00 gal/hr maximum input rating. Under no circumstances attempt to fire the EH oil burner under its 3.00 gal/hr minimum input rating or over its 6.00 gal/hr maximum input ratings.

NOZZLE INSTALLATION

In order to install or change the nozzle, the oil gun assembly needs to be removed from the burner. The EHASR, EHA, and EH burners has an arrow decal that lines up with the leading edge of the oil gun slot cover plate. This will help with reinstalling the oil gun in the proper position once the nozzle has been installed. See Figure 6 for part identification.

BURNER INSTALLATION

The EHASR, EHA, and EH oil burners were designed for furnaces, boilers, water heaters and a wide variety of commercial applications ranging from pressure washers & asphalt trucks The burner is supplied as a completely assembled unit. This burner should be installed into your appliance with the appliance manufacturer’s recommendations; if no recommendations are available it is up to the expertise of the installer.

NOTE: The burner must be installed in such a manner that all controls will be readily accessible for inspection, cleaning, adjustment, and repairs.

INSTALLATION OF MOUNTING FLANGE

Position the mounting flange on the furnace wall, adjusting orientation as necessary until the bolt pattern of the appliance allows the flange to sit flush. (See Figure 19 for flange dimensions.)

Note the orientation of the flange and remove it so that the flange gasket may be placed between the appliance wall and flange. Tighten the flange to the furnace wall.

Insert the burner tube into the flange and position it per Figure 20 on page 30. Tighten the flange onto the burner tube.

Figure 19– Adjustable Mounting Flange Dimensions

Air Band Adjustment Screw

Figure 20– Combustion Chamber Installation Recommendations

Note: The air tube length (DIM. A) is the distance from the front of the air tube retainer flange to the air tube cutoff where the air cone mounts in the tube. Note adjustable flange width.

STARTING PROCEDURE

STARTING BURNER

Be sure that the electrical breaker to the appliance is in the “OFF” position, set the thermostat to a temperature substantially above room temperature, and ensure the oil tank is filled, all valves are open, and controls set for operation. Adjust air supply on burner by loosening screw on interlocking air bands, and open the air band until black smoke is eliminated on start-up (see Figure 21).

Figure 21– Air Band Adjustment Screw Location

Open the ignition device mounting plate and turn on the electrical breaker.

Bleeder Valve

Next, bleed the pump by following steps 1-3 before starting the burner. See Figure 22 for the location of the bleeder valve on the pump.

Figure 22– Fuel Pump Bleeder Valve Location

Note: If the pump is set up in two pipe operation with the by-pass plug installed, bleeding the pump is not necessary.

1. Slide a 1/8” Vinyl hose on the bleeder valve as shown in Figure 23 and route the hose into a small container

Figure 23– Bleeder hose location

2. With the burner running, use a 3/8 inch wrench to open the bleeder valve about one-half turn (Figure 24). Allow oil

Do not run fuel unit dry for more than five minutes or damage to the pump may result.

All new installations should be re-inspected after one or two weeks of normal operation.

to drain into the container until a steady, clear bubble free oil stream is noticed. Close the bleeder plug.

Figure 24– Bleeder valve adjustment

Note: If safety lockout occurs during burner operation, reset after one or two minutes.

3. Close the ignition device mounting plate, and tighten the hold down clip screw

FINAL ADJUSTMENTS

At this point a final adjustment should be made by the use of a COMBUSTION TEST KIT. After operating for ten minutes to warm up the appliance, a smoke tester should be used to take a smoke reading. Smoke test should read no greater than #1 (Shell Bacharach scale), and less than a #1 smoke is desired. At times, a new heating unit requires more time than this to burn clean due to the oil film on the new heater unit surfaces. Recheck draft and take a CO2 reading over the fire and in the stack. If a large differential between CO2 readings is noted, air leakage is the most common cause. CO2 readings must be taken ahead of draft control, if used. The CO2 measured in the stack should be at least 10-12% for oil rates 1.00 gal/hr or below, and at least above 10% for oil rates over 1.00 gal/hr Units should be started and stopped several times to assure good operation. Open ignition device mounting plate, unplug solenoid valve lead, and check the oil primary control (if equipped) for normal operation see SEQUENCE OF OPERATION: BURNERS WITH R7284G

AND R8184G CONTROLS on pages 17-18. Check operation of limit controls and thermostat. Check for oil leaks.

SETTING COMBUSTION EFFICIENCY

1. Fire burner, adjust interlocking air bands until smoke from the exhaust changes from black to clear and see

through.

2. Record CO2 and smoke levels. If CO2 is low, close the air band by a 1/8 inch using a ruler or scale, and repeat

CO2 and smoke test. Continue this adjustment until desired CO2 and smoke levels are obtained. Record stack temperature.

3. Check lighting with cold and hot chamber.

4. Lock all adjustment screws.

FINAL CHECKS

Before beginning any maintenance work on the burner, be sure that all oil valves

from the tank are closed and electrical power to the burner is disconnected.

Be sure all screws are locked and the controls on heating unit are adjusted in accordance with the heater and control manufacturer’s instruction sheets.

Note: O2 % should be over 3 %, and for CO emissions the lower the better but, typical applications for pressure washers should be under 250 ppm, and under 125 ppm for boilers.

MAINTENANCE

The following routine maintenance operations should be performed on the burner once a year:

- Filter/strainer: The oil filter cartridge should be replaced once a year so the fuel oil will not become contaminated

and plug up fuel pump and nozzle of oil burner.

- Nozzle: The nozzle should be changed at least once a year before the start of the heating season. Replace with

proper nozzle.

- Electrode Settings: This is very important for reliable ignition of the oil; check these once a year in accordance

with the instructions provided in this manual. Replace electrodes if worn excessively or if electrode insulator is oil soaked or cracked.

- Fan and Blower Housing: This must be kept clean, free of dirt and lint; open transformer to check fan blades

from above. Be sure the electric power is off on burner when the transformer is opened up for this inspection

Components: If replacement of a burner component becomes necessary, always use parts recommended by the manufacturer. Specify part numbers and description when ordering. (In all communications, state burner model, serial numbers, and appliance manufacturers and appliance model designation).

L= Max total line length (ft.), H+R

H= Vertical distance in feet from bottom of tank to centerline of pump, or lift (ft.)

R= Horizontal distance in feet from tank to centerline of burner pump (ft.)

Q=firing rate capacity of fuel pump (gal/hr)

Figure 27– Fuel line sizing diagram for fuel tank below burner, burner setup in two-pipe

operation

Table 5: Max Allowable Fuel Line Lengths for two pipe operation

NOTE: Max. total line length L=H + R, values were calculated based off a fuel viscosity of 57 SSU. Elbows, valves & filters will further reduce total line length. It is recommended to avoid 3/8” lines where feasible.

One Pipe Operation

NOTE: For one-pipe operation (no return line) use the following line length equations 3/8” line: L=(6-.75H)/.0086Q 1/2” line: L=(6-.75H)/.00238Q

NOTE: If tank is above the pump, change the “-“ to a “+”

Sample Calculation for one pipe operation

If the fuel tank is installed below the ground and it is found that the distance from the bottom of the tank to the centerline of fuel pump is H=7 ft, ½ inch copper tubing is being installed, and the oil pump max flow rate is rated at 3 gal/hr according to the label, (Q=3 gal/hr), the maximum total line length (L) would be

L=(6-.75*(7))/.00238*(3) L≈105 ft. Now to calculate the maximum horizontal distance from the burner pump to the tank (R) R= L-H, R=105-7; R=98 ft. Note: If (6-.75H)=0 or a negative number, based off H≥8 it means that the pump will not be able to pull fuel from the

tank for that given lift (H), either run a return line or use a two-stage pump to overcome this issue.

4. A burner so repaired will then carry the LIMITED WARRANTY equal to the unexpired portion of the original burner LIMITED WARRANTY.

5. If inspection by WAYNE does NOT disclose any defect covered by this LIMITED WARRANTY, the burner or burner component(s) will be either repaired or replaced at the expense of the

customer and WAYNE”S regular charges will

apply.

6. If the original manufacturer of a burner component offers a warranty greater than either of our LIMITED WARRANTIES described above, then this portion will be added to our LIMITED WARRANTY.

This LIMITED WARRANTY does NOT cover products which have been damaged as the result of accident, abuse, misuse, neglect, improper installations, improper maintenance or failure to operate in accordance with WAYNE’s written instructions.

These LIMITED WARRANTIES do not extend to anyone except the first purchaser at retail and only when the burner is in the original installation site.

IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE SHALL BE LIMITED TO THE DURATION OF THE LIMITED EXPRESS WARRANTIES CONTAINED HEREIN. WAYNE EXPRESSLY DISCLAIMS AND EXCLUDES ANY LIABILITY FOR CONSEQUENTIAL OR INCIDENTAL DAMAGES OF ANY NATURE FOR BREACH OF ANY EXPRESS OR IMPLIED WARRANTY.

Some states do not allow limitation on how long an implied warranty lasts, so the above limitation may not apply to you. Also, some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. WAYNE neither assumes or authorizes any person to assume for WAYNE any other liability or obligation in connection with the sale of these products. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

ALL GAS BURNERS manufactured by “WAYNE” will be similarly warranted for eighteen(18) months from date of manufacture except where original manufacture offers a

greater warranty. (Reference #6 below) THESE LIMITED WARRANTIES DO NOT APPLY UNLESS THE BURNER

COVERED BY IT IS PROPERLY INSTALLED BY A QUALIFIED, COMPETENT TECHNICIAN, WHO IS LICENSED WHERE STATE AND/OR LOCAL CODES PREVAIL, AND WHO IS EXPERIENCED IN MAKING SUCH INSTALLATIONS, in accordance with NFPA #31 of the national fire protection association and in accordance with all local, state and national codes.

Any IN-WARRANTY burner component which is defective in material or workmanship will be either repaired or replaced as follows:

1. Fuel pumps, motors, transformers, gas valves, and controls should be returned to an authorized service station or distributor of WAYNE for determination of applicability of this LIMITED WARRANTY as to either repair or replacement, where said service station or distributor is reasonably available in the customer’s locality. The manufacturers of burner components regularly publish and distribute listings showing the locations of their network of service stations. Where such local service is NOT available for the burner components described above or other burner parts are involved, these items should be returned, freight prepaid, to WAYNE Service Department, 801 Glasgow Ave, Fort Wayne, Indiana 46803.

2. Burners and/or component(s) determined to be covered under this LIMITED WARRANTY by WAYNE shall be repaired or replaced at WAYNE’s sole option.

3. WAYNE is not responsible for any labor cost for the

removal and replacement of said burner or burner components and equipment associated therewith.
