Safety Statements

STOP FOR SAFETY!

Safe assembly, operating and maintenance practices should always be

followed whenever using any equipment. Wherever you see the caution sign,

extra safety precautions should be taken.

You must stop, read, and carefully follow the safety instructions before proceeding.

READ THROUGH THE ENTIRE MANUAL

It is recommended to read through the entire manual before beginning your

installation and/or operating your furnace. Follow all steps exactly.

UL LABEL AND NFPA PRACTICES

Areas of this manual refer to Underwriters Laboratories (UL)

and the National Fire Protection Association (NFPA).

UL & NFPA are non-profit organizations. This furnace must be installed according to NFPA codes.

UL is the oldest and largest public safety testing laboratory in the world. All furnaces in this manual are Listed by the UL. They have passed all safety and efficiency requirements for both gas and oil in the U.S. The UL Listing label is also your assurance that UL employees inspect our furnaces during the manufacturing process. This can happen several times a year on an unannounced basis.

NFPA Codes, Standards, recommended practices, and guides referred to in this document are approved by the American National Standards Institute. State and local codes are adopted from these standards.

DANGERS-CAUTION-FIRE HAZARDS

(Burn wood logs or coal only)

Do not install a power humidifier on the warm air plenum.

Do not load wood above secondary air tube. Doing so will cause over-fire and damage to combustion

chamber could result.

Do not attempt to light a wood or coal fire when oil or gas vapors are present. An explosion or flashback

could cause personal injury.

Do not install on combustible floor.

Load wood or coal carefully or damage may result to fire brick or refractory pot liner.

Fire the oil or gas burner at least once each week during the heating season. This will insure clean nozzles

and electrodes.

Inspect air filter regularly. Clean or replace as necessary. Filter size is 20" x 25" x 1".

If an over-fire situation should occur, be sure ash door and fire door are closed. Turn thermostat down to close primary air damper.

In the event of an electrical power failure, remove air filter and be sure ash door and fire door remain closed.

In the event of a soot or creosote fire, call your fire department immediately. Turn thermostat down to close primary air damper and make sure ash door and fire door are closed.

FURNACE CONTROL This is the solid-state

control that coordinates the gas or oil burner function with the wood/coal damper so that your home is always comfortable using your choice of fuels.

MORE HEAT EXCHANGE SURFACE

MEANS LESS HEAT UP THE CHIMNEY

The secondary heat exchanger is made up of type 304 Stainless Steel tubes, which the heat produced by the furnace, must pass through before entering the chimney. This feature increases the heating surface to 54 square feet. Standard gas or oil furnaces have only 25-30 square feet.

GAS BURNER OPTION FOR AUXILIARY

FUEL Our gas model comes with a Wayne P250

AF DIN hi-efficiency gas burner. This burner features a Honeywell electronic ignition and gas valve. It is certified by Underwriters Laboratories to provide up to 80.1% steady state efficiency. It can be switched from LP Gas to Natural Gas or visaversa. This burner can be interchanged with our Wayne model MSR oil burner at your option.

burner side. This firebrick not only protects the steel from the extreme combustion temperatures in the firebox, but it also retains a substantial amount of

heat after the wood/coal fire burns down.

AFTER-BURNER JET SYSTEM GIVES

{

MAXIMUM SOLID FUEL BURNING EFFICIENCY Twenty percent of the air required

for proper coal/wood combustion is drawn in above the firebox, and then distributed around the top of the flame to create an afterburner effect. Forty percent of the energy in wood/coal leaves the initial flame in the form of an unburned gas (smoke). This patented system burns these gases, thereby substantially increasing the efficiency of the wood or coal.

2 DIFFERENT STYLES OF HEAVY CAST

IRON GRATES It is imperative that 80 percent of

the air for combustion enters the firebox from below a wood coal grate to insure an efficient and clean burning fire. Our standard heavy cast iron grate is adequate for a wood fire. A much heavier cast iron shaker grate is also available as an option for dense

coal use.

THE OIL (OR GAS) BURNER FIRES INTO

AN ENGINEERED PYROLITE HIGH TEMPERATURE CERAMIC CHAMBER WHICH ASSURES COMPLETE COMBUSTION This flame is then directed

horizontally into the wood/coal firebox to automatically ignite those fuels. This design assures the gas or oil burner to be free of any wood/coal smoke from the fire box.

THE EAGLE I INCORPORATES AN EASY

ACCESS CLEAN-OUT DOOR TO MAINTAIN TOP HEATING EFFICIENCY

This is an openable door which connects the four secondary heat tubes to the flue pipe that leads to the chimney. Keeping the inside of your furnace clean insures high efficiency.

2-INCH THICK HI-TEMPERATURE

FIREBRICK SURROUNDS THE WOOD/COAL FIRE The EAGLE I furnace

features 180 pounds of firebrick. It is 18 inches high on the side opposite the burner and the backside of the firebox. It is 9 inches high on the

FUEL If oil is your preference for a back-up fuel,

your burner will be a Wayne model MSR 321-009 hi-efficiency oil burner. Features are a Stainless Steel flame retention head and Honeywell Premium controls. It is certified by Underwriters Laboratories to provide up to 80.1 % steady state efficiency. If at some time in the future, you decide you would rather have LP or Natural Gas as your backup fuel, this burner can be interchanged with our Wayne

P250 AF DIN gas burner. (A nice insurance policy.)

AIR CIRCULATING BLOWER AND

MOTOR The EAGLE I is designed with 10 inch

wide, ten inch- diameter belt drive blower. This oversized blower turns slower than ordinary furnaces because of its large size. It is therefore quieter than most furnaces, Each EAGLE I is equipped with a premium Class A motor with Class B insulation, which means it will operate in a higher temperature atmosphere. This motor also features a 1.35 service factor, which means it has 35% more power than a standard motor of the same size. Up to four tons (48,000 BTU’s) of air conditioning can be added to an EAGLE I.

MOUNTING THE THERMOSTATS

The thermostats must be mounted on an interior centrally located wall. Place them away from direct sunlight, drafts, and approximately 5 feet above the floor. It is not required that they be level. Place them right next to each other. See Fig. 17.

Two Honeywell digital thermostats are furnished with all multi-fuel furnaces. The larger thermostat controls your gas, oil or electric, whichever back-up fuel you have. It offers one temperature setting for when you want the burner to start. This is in the event your wood supply is inadequate in keeping your home at its temperature setting. It also has a night setback feature that allows you to keep lower temperatures at desired times. This thermostat also controls the air conditioning, if applicable.

The smaller thermostat controls the wood/coal room temperature. It does not have a night setback feature.

If you have no plans for air conditioning you will need a 3-wire thermostat cable from your furnace to your thermostat. If you intend to install air conditioning a 5-wire thermostat cable is required.

FIG. 17

TYPICAL THERMOSTAT SETTINGS

Place 3 or 4 8” diameter logs into wood chamber. Set wood thermostat 5 degrees above room temperature. Set oil/gas thermostat 10 degrees above room temperature. Burner will then ignite and start the wood burning. When wood is adequately burning, reset gas/oil thermostat to 5 degrees below desired room temperature. Set wood thermostat to desired wood temperature. With the proper amount of wood in the firebox, the wood thermostat will keep the room temperature at the wood thermostat setting. When the wood is no longer able to keep up with the heating demands of your home and the temperature falls to the oil/gas thermostat setting, the burner will come on until that thermostat is satisfied.

FUEL TANKS AND FUEL LINES

Fuel tanks and fuel lines must be installed in accordance with requirements of NFPA 31.

If fuel lines are under 30 feet in length, it is satisfactory to use 3/8" O.D. copper tube. Never use tube smaller than 3/8" O.D. If the lines are over 30 feet in length, we recommend 1/2" O.D. tube. Use good flare connections on the fuel lines and, whenever possible, avoid splicing the tube. Never make a splice or joint underground. Whenever possible, avoid overhead lines; avoid kinks and traps in the lines. Do not fasten fuel lines directly to floor joists, sills, or girders. Whenever possible, support fuel lines with sound-absorbing devices.

SINGLE LINE SYSTEM

When fuel does not have to be lifted from tank to burner use a single line hookup. A single line system can be used when outlet on fuel tank is higher than inlet on burner.

FIG. 18

TWO LINE SYSTEM

To lift fuel from tank to burner use a two-line system. On outside buried tanks, install a supply line from tank to burner and return line from burner back to tank. The supply line is called the suction line. The suction line should extend down within a few inches of the bottom of fuel tank.

OIL FILTER

A fuel filter should be used with either an outside or inside fuel tank. In all cases install the filter in accordance with local codes. The filter should always be installed inside, near the furnace. An inside tank and any internal or external fire or flame appliance being served by the tank must be at least 5 feet away from the furnace. New oil replacement cartridges should be installed annually or as required. Always use the new gasket that is supplied with the replacement cartridge. Tighten the top of the filter carefully and check the gasket for proper fit.

FILL AND VENT PIPES

Fuel tanks must be equipped with a fill pipe and a vent pipe. Fill pipes should be terminated in a convenient place for filling. They should be equipped with a watertight cap. It is recommended that 1-1/4" pipe be used for the vent. The vent should extend outdoors served by the tank and

GAS PIPE SIZING

Check with your local gas supplier to determine total gas load for all your gas appliances. Size pipe accordingly.

GAS PIPING

All piping must comply with local codes. In the absence of local codes, follow the national fuel gas code ANSIZ-

233.1. A sediment trap or drip leg must be installed in the supply line to burner. (See Fig. 19)

A union must be installed in the gas line. It should be adjacent to and upstream from the control manifold. It should be downstream from the manual main shut-off valve.

A manual shut-off valve must be installed in the gas supply line. It must have a 1/8" N.P.T. plugged tapping for test gauge connection.

The building structure should not be weakened by the installation of the gas piping. The piping should not be supported by other piping. It should be firmly supported with pipe hooks, straps, bands or hangers. Butt or lap welding pipe should not be bent.

The gas piping should be installed so as to prevent an accumulation of condensation. It must be protected against freezing. A horizontal pipe should pitch so it grades toward the meter and is free from sags. The pipe should not be run through or in an air duct or clothes chute.

Method of Installing a

Tee Fitting Sediment Trap

FIG. 19

After the piping and meter connections have been checked for leaks, purge system of air. Be sure to relight all pilots on other appliances.

The gas line should be a separate supply direct from the meter to burner. A new pipe should be used. Locate it so a minimum amount of work will be required in future servicing. The piping should be installed so it is durable, substantial and gas tight. It should be clear and free from cutting burrs and defects in structure or threading. Cast iron fittings or aluminum tubing should not be used for the main gas circuit. Joint compounds (pipe dope) should be used sparingly on male threads only. The joint compounds should be approved for all gases.

CAUTION: Do not use any smoke pipes less than 24 gauge between furnace and chimney.

CONNECTING SMOKE PIPE

Set the smoke pipe end of the furnace as close to the chimney as possible. The rise of the smoke pipe toward the chimney must be at least one inch per linear foot of pipe. Do not exceed 10 feet in length. A clean out tee should be installed for removal of soot and fly ash.

Do not install smoke pipe longer than necessary to reach chimney. This is for purposes of trapping heat. The smoke outlet temperature is designed to carry by-products of combustion out through chimney. The smoke pipe must not pass through any combustible material.

WARNING: No damper, heat saver, or automatic vent damper device should be installed in or on smoke pipe. Except the barometric draft regulator.

FIG. 24

The smoke pipe entrance into a masonry chimney should be at least 2 feet above the clean out. The smoke pipe must not extend into the chimney beyond the inner face of the chimney liner.

LESSER CLEARANCES TO COMBUSTIBLE MATERIALS ALLOWED

This furnace is UL Listed, requiring 18 inches from smoke pipe to a combustible surface. A reduction of 9 inches from a combustible ceiling and 12 inches from a combustible wall is allowed if the space is insulated according to NFPA 90B, table 6-5.1.2.

WARNING: DO NOT CONNECT THIS FURNACE TO A CHIMNEY SERVING ANOTHER APPLIANCE

WARNING: CHECK YOUR CHIMNEY. The chimney should be no less than 8 inches inside diameter or equal. The

chimney is a very important part of your heating system. It must be the right size, properly constructed and in good condition. No furnace can function properly with a bad chimney. The chimney must supply a draft of at least .03 Water Column. If possible, use a 15 foot or higher chimney. Add an additional foot to chimney for each 1000 feet of elevation above sea level.

PROPER CHIMNEYS

The National Fire Protection Association (NFPA) requires that all factory built chimneys be Listed and installed in accordance with conditions of the Listing in the manufacturers instructions. NFPA also requires that your chimney extend at least three (3) feet above the highest point when it passes through the roof and at least two (2) feet higher than any portion of the building within ten (10) feet of the chimney.

Factory built chimneys must be what NFPA refers to in NFPA 211 1-5.217.4 as Type HT. HT is an abbreviation meaning high temperature.

Masonry Chimneys as referred to in NFPA 211 1-5.2.17.6, a field constructed chimney of solid masonry units, bricks, stones, listed masonry chimney units, or reinforced concrete that is lined with suitable chimney flue liners and built with the provisions of Chapter 4 of this standard.

As described in NFPA 54 (National Fuel Gas Code) section 7.5.5 (c) A Listed combination gas and solid fuel appliance equipped with a manual reset device to shut off gas to the main burner in the event of flue gas spillage shall be permitted to be connected to a single chimney flue. The chimney flue shall be sized to properly vent the appliance.

All gas-solid fuel and oil-solid fuel combination furnaces in this manual are Underwriters Laboratories Listed for one flue.

COMBUSTION AIR

Make-up outside air must be provided to furnace for proper fuel combustion. This is provided by openings to outside of building. These openings shall have unobstructed areas not less than the areas of the flue pipe. See Figs. 25, 26, 27

IMPORTANT:

Outside air is needed to replace air used by the burner and wood combustion process. Outside air is required to replace air used for taking the by-products of combustion out the chimney. Outside air is needed to replace air expelled by kitchen or bathroom fans. It is also needed to replace air expelled by water heater chimneys or fans. See Figs. 25, 26, 27

Failure to provide outside air to the furnace area will result in negative pressure, or vacuum, in the home. Smoke from the wood fire may not be drawn up the chimney. This causes creosote buildup and sometimes causes smoke to enter furnace room. See Figs. 25, 26, 27

WARNING: You must provide for enough fresh air to assure proper combustion. The fire in the furnace uses

oxygen and must have a continuous supply. The air in a house contains only enough oxygen to supply the furnace for a short time. Outside air must enter the house to replace that used by the furnace.

FURNACE LOCATED IN CONFINED SPACE

When the furnace is in utility room, install two open grilles.

(See Fig. 28.) Place them in a wall or door opening to the

rest of the house. One grille will supply combustion air. Locate it near the floor. The other grille is for ventilation. Locate it close to the ceiling. Each grille must have a free area. It should be not less than one square inch for each 1000 BTU/hr. of the total input rating of appliances in confined space.

FOR EXAMPLE: Your furnace is rated at 150,000 BTU per hour. The water heater is rated 30,000 BTU per hour. The total is 180,000 BTU per hour. You need two grilles, each with 180 square inches of free opening. Metal grilles have about 60% free (open) area. Therefore, you need two metal grilles with 300 square inches each of louvered area. The height should be about half the width.

OIL FIRING THE UNIT

To start the oil burner on a new installation

1. Check to make sure there is oil in the storage tank. No. 2 fuel oil may be used if tank is in the basement or buried below ground. No. 1 fuel oil is recommended if the tank is outside and above ground.

2. The oil burner was started and tested at the factory. Double check to make sure the proper oil burner nozzle is installed and electrodes are set according to the oil burner manual.

3. Turn oil tank valve lever to ON.

4. The furnace should be connected to a 110-Volt, 20 Amp circuit protector (fuse or circuit breaker.) Turn switch to “ON”.

5. Set burner thermostat 10 degrees higher than room temperature. If the furnace is connected to the oil tank with a single line, air may have to be purged to the burner. (See burner manual). If there is no air in the oil line, the burner will start. If air is in the oil line, the cad cell will not see a flame and shut down. Wait 5 minutes and turn back on. The correct pump pressure of 100 psi was set at the factory. The draft regulator that is connected to the chimney pipe must be set a .03” Water Column negative to the chimney with the burner operating at least 5 minutes.

6. Refer to burner manual for service tips.

STARTING BURNER AFTER IGNITION FAILURE

Before proceeding, find the cause of ignition failure. It may be a plugged nozzle, dirty electric eye, soot on electrodes, air in the line, or plugged oil line. Do not attempt to restart burner when excess oil has accumulated or if the combustion chamber is very hot. Press the reset button on primary relay control and burner should start. Do not attempt this more than twice. If burner fails to operate, call a service technician.

BEST WOOD TO BURN

All solid fuel, whether it is coal, pine, oak or any grain has about 12,000 BTU's per pound if its moisture content is zero. Wood that has been cut, split and air dried for 2 years has about 8,000 usable BTU's per pound. Hardwood such as oak or hard maple has nearly twice the BTU's per cord as pine or aspen because it is nearly twice as heavy.

Freshly cut wood has about 50% moisture content. Wood that has been cut and split for 2 years has about 20%. Wood must reach at least 435º to ignite. High moisture content wood does not allow the gases in wood to get hot enough to provide complete combustion, thereby creating smoke and creosote, which is usable energy, but wasted because of incomplete combustion.

Yukon-Eagle furnaces are designed to wring the most energy possible from each log. Your furnace is designed to allow the primary air under the grate to create the initial burning. As the wood burns, gases, which contain 40% of the energy in the wood, escape to the top of the flame. The patented secondary air system (the round tubes between the firebrick) draws room air into the tubes and provides oxygen to the firebox to burn these gases. The result is you will use up to 75% less wood than stoves, furnaces or outdoor boilers without these features.

Operating Instructions

STARTING WOOD FIRE WITH GAS OR OIL BURNER

Place three or four 6 to 8 inch diameter logs in the firebox. Set the temperature on the small thermostat to the desired setting. Set the temperature on the larger thermostat above room temperature. The flame from the burner need not touch the wood to ignite.

HAND FIRING WOOD

Set the small thermostat above room temperature. Set the larger thermostat below room temperature. The damper to the firebox should now be open.

Place paper and kindling in firebox as you would in a fireplace or campfire. Add logs to top of fire once kindling is burning. Reset small thermostat to desired room temperature.

Never leave ash drawer open, either to start fire or to provide more heat. The furnace is designed to provide adequate heat with the ash drawer closed.

FIG. 33

WARNING: Never operate furnace with ash drawer open. It could cause fire to burn at extreme temperatures, causing metal fatigue, firebox failure, and unsafe duct temperature.

CAUTION: OVERLOADING WITH WOOD Do not overload your furnace with wood. Failure or damage to the firebox could result. Never allow the hot coals to build up above the lower firebricks.

DANGER: Never burn materials other than coal or wood logs, preferably split and dried. A chimney fire or heat

exchanger failure could result. This includes large amounts of corrugated boxes, wood shavings, paper scraps, dried Christmas trees, coke, garbage, tires or other burnable products.

IMPORTANT: Keep ash drawer empty. Primary air to the wood chamber travels under the grate. The grates will warp and eventually burn out if ashes are permitted to build up above them.

CAUTION: RESTRICTED USE DURING ELECTRIC POWER FAILURE OR FURNACE FAN FAILURE

Furnace may be converted to a gravity system. The following directions must be followed carefully to avoid an over-fire situation.

1. Remove access door to blower compartment and remove air filter. Then replace access door. Keep ash drawer tightly closed. Do not tamper with wood primary air control. Load wood to half the recommended normal height, approximately 4 inches above grate.

2. Do not overload, no furnace fan is available to rapidly carry away the heat. Load small amounts of wood frequently until power is restored.

3. Open all air registers and remove all obstructions near them. Keep children away from air registers or burns could result.

4. Primary air damper and burner will operate automatically when electric power is restored.

Operating Instructions

WHAT SIZE COAL SHOULD I BURN?

The air space between the furnace grates is 1/2 inch. Therefore, coal smaller than 1/2 inch can fall through the grates into the ash pan.

• Pea size coal ranges from 9/16 to 11/16 inch.

• Nut size coal ranges from 1-3/16 to 1-5/8 inches.

• Stove size coal ranges from 1-5/8 to 2-7/16 inches.

Nut size is preferred by most people and is recommended for use in this furnace.

Anthracite coal is hard and burns like charcoal that is used in your barbecue grill. The coals must touch each other to ignite. Therefore, the smaller the coal, the easier to ignite. Stove coal is not likely to touch each other because of its size.

Bituminous coal is soft and not as desirable as hard coal. It creates dust when handled. It also produces large amounts of smoke and soot when burned at a slow rate. Soft coal from some areas of the country contains higher sulfur content. A large portion of it may be removed if the coal is cleaned.

FIG. 34

Western lignite coal should be burned the same way you would burn wood. (Refer to wood burning instruction on previous pages.)

SHAKING THE GRATES

HOW TO START A COAL FIRE

Place a small amount of crumpled paper and kindling wood on the ash-covered grates.

Ignite paper and after wood is burning briskly, cover with a thin layer of coal. As first layer of coal becomes ignited, add more coal gradually. Add coal until fire bed is built up to approximately 6 inches deep. As fresh coal is added always leave some of the glowing coal uncovered.

Draw the top red coals toward the front of the firebox. Pile the fresh coals toward the back.

The grates must be protected from direct contact with the fire. This is done by placing a layer of ash, one (1) or two (2) inches thick on grates. The ash left on the grate will help prevent overheating of the cast iron grates. It also keeps coal from falling through the grate's opening.

MAINTAINING A COAL FIRE

Bituminous coal should be built into a cone shape once the fire has started. When re firing, break up the cone a little using a poker. Especially if it has caked over to form a crust. Be careful not to mix the coal as this increases the chance of forming clinkers.

Shaking a fire should only be done if room is needed for fresh coal. Also, if the ash accumulation on the grates is excessive. Generally, the grates need only be shaken once or twice a day.

Shake the grates using a few short strokes. Stop when the first red coals appear in the ash pan. Undershaking restricts the amount of air that reaches the fire. Over-shaking may cause the fire to go out.

CAUTION: Do not use kerosene, gasoline,

thinners, etc. to start a coal fire.

A coal fire should never be poked or broken up. This causes ash to come to the surface of the coal bed. The ash may fuse into lumps or clinkers which interfere with proper burning.

Anthracite Coal - To bank the fire for the night, pile the coal higher to the back of the firebox. Allow it to slope toward the fire box door. Always leave some red or burning coals uncovered in the front of the firebox.

Bituminous Coal - To bank fire for the night, shake the fire and add coal, forming the center cone. Allow enough time for the volatiles to burn off before closing the fire door.

OPERATING INSTRUCTIONS FOR BURNING COAL ON 1/2-INCH OPENING GRATES (Optional)

The following instructions are for burning various types of coal, storage of coal, and the cleaning of the furnace.

Some coal is oil-treated at the mine. Some users have indicated that it tends to make the coal difficult to start.

Burning coal requires some patience and a regular procedure. With improper tending, a coal fire can go out in a short time. Once the fire starts to go out, it is almost impossible to reverse.

After a coal fire goes out, the coal must be removed from furnace. Then the starting process can be repeated.

Our coal burning instructions are general, as coal comes in various sizes and types. Anthracite coal is most recommended as it burns with little smoke when burning properly.

CAUTION: Burn Anthracite, Bituminous, or Lignite

coals only. DO NOT BURN Petroleum, Coke, or Cannel Coals.

IGNITION TEMPERATURE OF COAL AND WOOD

How hot does coal have to get to ignite? Following are examples of the ignition points of various materials:

• Paper ignites @: 350°F

• Wood ignites @: 435°F

• Western lignite ignites @: 630°F

• Low volatile bituminous ignites @: 765°F

• High volatile bituminous ignites @: 870°F

• Anthracite coal ignites @: 925°F

GRATE CARE - ASH REMOVAL

It is necessary that ashes be removed from the ash pan on a daily basis. The ashes should never be allowed to accumulate high enough to come in contact with the grates. Such a condition could cut off necessary air circulation. It could also result in a warping or burnout of grates.

ASH DISPOSAL

Unlike wood ashes, coal ash should not be spread on the garden. The minerals in coal ash contains several chemicals which could be harmful to plant life.

RECOVERING UNBURNED COAL

Screen coal ashes through a piece of 1/4 inch or 3/8 inch mesh hardware cloth. This helps recover any unburned coal that has fallen though grates.

STORAGE OF COAL

Coal may be stored indoors or outdoors, with some precautions:

FIG. 35

1. The storage area must be free of materials that are easily burned. Examples are paper, wood, rags, and leaves.

2. Wetting and drying of coal should be avoided. Outside storage's should be protected from rain or snow. Wet coal should not be piled on dry coal.

3. Locate the storage area in a place that is 75º F or lower.

4. Nut coal weighs approximately 58 lbs. per cu. ft. A storage bin 4-feet square by 4-feet high will hold 2 tons.

IMPORTANT: Never smother fire when adding fresh coal.

Maintenance

SMOKE PIPE, CHIMNEY AND SECONDARY HEAT EXCHANGER

Do not burn green or freshly felled wood. This may cause creosote and soot to build up in chimney, smoke pipe, and secondary heat exchanger. These should be checked and cleaned several times each heating season.

CLEANING FURNACE AND CHIMNEY FLUE PIPES

Frequently check and clean the furnace flue pipes and chimney. Soot and fly ash should not be allowed to build up on any of these surfaces. Chimneys are best cleaned professionally.

FURNACE BLOWER ADJUSTMENT

Set adjustable motor pulley so blower will give approximately 80-90º F temperature rise through furnace. After pulley has been adjusted check bolt as follows:

The belt is drawn tight during shipment. Therefore both belt tension and sheave alignment must be rechecked by the installer. This is done when the furnace is placed in

service.

Improper belt tension and pulley misalignment are the major causes of furnace fan noise. It also causes failure of belts and bearings.

Sheave alignment is determined with a straight edge held across outer face of fan sheave. The face of motor sheave should be parallel to the straight edge at all points. See Figs. 36-38

Proper belt tension is more difficult to determine accurately. Too little tension will permit slippage causing belt wear. It may cause noise or squealing when the motor starts. Excessive tension increases motor load. It may cause the oil film between shaft and bearing to fail. This, in turn, causes the bearing to seize or burn out.

FIG. 36

FIG. 37

The proper belt tension is the minimum which will drive the blower without slippage. This varies with sheave diameter, fan size, and motor starting torque characteristics. The practical belt tension can best be determined by actual experience. When in doubt it is better to have the belt too loose rather than too tight. Belt tension can be judged by grasping the belt as shown. The belt should be deflected approximately one inch, without the motor moving, when moderate pressure is applied. See Fig. 39

DUCT WORK AND BLOWER SPEED ADJUSTMENT

Supply and return duct system should be sized properly for efficient operation. Normal air temperature rise through the furnace should be adjusted to approximately 80-90º F. Proper blower speed adjustment, in conjunction with adequate duct work are necessary to achieve this.

A high temperature rise will result in excessive fuel usage. This is due to the high stack temperature that always accompanies a high air temperature rise. It can also cause premature heat exchanger failure.

To perform temperature rise check, start furnace and let it run a minimum of 10 minutes. (Be sure all duct work is complete and furnace is in its normal operating condition). Place #1 thermometer in the return duct near the furnace. Place #2 thermometer in the supply duct near the furnace, but not in the plenum. After 10 minutes or more operation, take thermometer readings. Supply air temperature should be no more than 80-90º higher than return air temperature.

Air temperature rise can be lowered by:

1. Increasing blower speed.

2. Additional supply or return outlets.

3. Lowering firing rate.

TESTING INSTALLATIONS FOR EFFICIENCY

A Draft gauge must be used. Draft in smoke pipe must be set at .03 Water Column updraft. Failure to set properly will cause fuel to be wasted, heating will not be satisfactory, fast buildup of creosote in heat exchanger and chimney may occur and cause damage to your heating system.

The draft regulator will afford the user maximum fuel efficiency, however, the finest draft regulator in the world cannot increase the efficiency of a heating system if the system as well as the regulator is not in proper adjustment.

Basically, stack temperature and percentage of CO2 are

a measure of stack losses for any fuel. Therefore, many of the basic principles can be and should be applied to oil-fired furnaces as well as for those burning solid fuels.

In preparation for these tests, the following should be checked. The Draft Regulator installed should be:

• plumb and level

• in the same room as the unit

• on the side of a vertical, sloping or horizontal smoke pipe

• located close to the furnace

Drill two holes approximately 1/4 inch in diameter in the flue pipe between the outlet from the furnace and the Draft Control.

Insert a stack thermometer in one of the holes and leave it there continually during the test so that you can refer to it at any time. See Fig. 40

FIG. 40

Maintenance

TEST PROCEDURE

Step 1.

Set the thermostat high enough so that the unit will run for at least 15 minutes, the maximum time that should be required for the test. Let the unit operate enough for the stack temperature to stabilize.

Step 2.

For your initial set of readings, set the Draft Regulator so that there is .03 Water Column Draft in the smoke pipe between the flue outlet and draft regulator. A manometer must be used to properly set the draft to .03” WC.

Step 3.

Insert the sampling tube of the CO2 tester in the hole that you have drilled adjacent to the stack

thermometer and find the percentage of CO2 in the sample of the products of combustion. Follow the

instructions of the manufacturer of the instrument you are using.

Step 4.

Use efficiency finder chart or stack loss slide rule to determine efficiency. Be sure to subtract room temperature from stack thermometer reading and use this net stack temperature for determining the efficiency.

Step 5.

Insert end of smoke tester into same hole as was used to test for CO2 and perform the smoke test.

Step 6.

The filter paper from the smoke test, when compared to the standard, must be determined and be found to be satisfactory. It should never be greater than #2, preferably #1 or zero, depending on local requirements or your own service standard.

Repeat steps 3, 4, and 5 as needed, adjusting the air shutter on the burner and draft regulator until you obtain the highest possible efficiency. It is desirable to have a high CO2 reading and low stack temperature with a minimum smoke reading.

OIL BURNER MAINTENANCE

MAINTENANCE AT THE END OF THE HEATING SEASON:

1. Shut off electric current to burner at fuse panel.

2. If oil filter has not been cleaned recently, it should be removed and cleaned. (Consult instruction card furnished with fuel unit).

3. Oil storage tank should be kept filled to prevent water vapor from collecting. It is suggested the valve in the suction line be closed. Oil storage tank should be cleaned every 2 or 3 years. This is to remove any sediment or water that has collected in tank.

MAINTENANCE AT THE START OF THE HEATING SEASON:

1. It is advisable to have a service technician inspect and service your burner.

2. Heating plant, smoke pipe and chimney should be cleaned and checked for repairs.

FIG. 44

3. It is advisable to have the entire electrical system inspected before putting the burner into operation. This is due to it standing idle for the summer months. This should include primary relay, limit control, thermostat.

Check the electrodes for carbon and cracks in insulators. Also check for corrosion on all terminals of the electrodes and transformer.

AIR FILTER MAINTENANCE:

Check and clean monthly. Change filter at least twice a year.

BLOWER MOTOR MAINTENANCE:

If motor has oil caps, oil twice yearly.

CAUTION: The furnace has a high efficiency "fiber-type refractory" combustion chamber. Normal servicing of this unit does not require cleaning of the combustion chamber. Use EXTREME caution if it becomes necessary to work in the area of the combustion chamber. This pyrolite chamber should be checked monthly. Replace if damaged or worn.

GUN ASSEMBLY ADJUSTMENT

The gun assembly can be adjusted in the slot of the fan housing. This is done by loosening the screw holding the slot cover in position. Adjust nozzle tip so it is located 7/8" behind the front face of the burner cone.

FIG. 45

Maintenance

HOW TO PREVENT RUST AND CORROSION

At the end of each heating season, clean both primary and secondary heat exchangers. Also, clean the ash pan thoroughly. Paint the inside of the heat exchanger with automobile crankcase oil. This will decrease rusting caused by summer moisture.

The black paint on firing door area may wear or burn off. It can be repainted with a high temperature, flat black, air-drying paint.

CLEANING THE CHIMNEY, SMOKE PIPE AND HEAT EXCHANGER

Avoid chimney fires. On a regular schedule, check for creosote and soot buildup in chimney, smoke pipe, and heat exchanger. They must be kept clean. Keep a professional chimney sweep in mind if you have access to one.

Steel brushes are the safest for cleaning metal surfaces. Salt solutions and some chemicals may damage metal surfaces. Do not over fire your furnace. Do not burn anything that combusts in seconds. Excessive fuel temperatures may result, thereby igniting creosote.

CAUTION: In case of chimney fire, call the fire department immediately!

CAUTION: Extinguish the fire in the furnace. Do this by setting the

thermostats all the way down to close the primary air damper and oil burner. Empty fire chamber and ash pan into safe, fireproof container.

NOTE: Do not use your furnace until a professional inspection has been made. They should inspect your furnace, smoke pipe and chimney.

DISPOSAL OF ASHES

Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground. Place the container well away from all combustible materials, pending final disposal. Ashes can be disposed of by burial in soil or otherwise locally dispersed. First, the ashes should be retained in the container until all cinders have thoroughly cooled.

To clean the chimney, obtain a stiff brush with an extendible handle. Then insert the brush into chimney from the top. Continue the brushing and sweeping downward until entire length of chimney is cleaned.

After cleaning chimney, debris will be at the bottom of chimney at the clean-out opening. Open clean-out door and sweep debris into a metal container.

The smoke pipe, from furnace to chimney, can be cleaned with an 8-inch diameter brush. A smaller brush can also be used. For cleaning the secondary heat exchanger you can use a steel brush. Use a 4 x 6” brush for the Eagle I - Husky and a 3 x 8” brush for the Eagle II - Polar, with a flexible steel handle. The primary heat exchanger can be cleaned with any steel brush. A furnace vacuum cleaner may be used.

NOTE: Soot will act as an insulator which causes

less heat to be transferred into your duct system. It also causes more heat out your chimney. Both reduce the efficiency of the wood and fuel being burned.

CREOSOTE-FORMATION AND NEED FOR REMOVAL

When wood is burned slowly, it produces tar and other organic vapors. This combines with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire.

The chimney connector and chimney should be inspected at least twice monthly during the heating season. This is to determine if a creosote buildup has occurred.

If creosote has accumulated it should be removed to reduce the risk of a chimney fire.

CAUTION: Before cleaning chimney, smoke pipe, and furnace, turn electrical

power off to furnace and other appliances connected to chimney. Be sure wood fire is out and inside of furnace is cool.

Maintenance

SMOKE IN THE FURNACE ROOM

This condition is usually caused because smoke is not being drawn up through the chimney. Other causes could be a failed (firebox)heat exchanger. Check with your qualified furnace service provider.

Chimney causes:

1. Fresh air for combustion must be supplied to the furnace room.

2. Cold chimney. Warm air rises and cool air falls. Outside chimneys are cold, which can cause downdrafts until the chimney heats up. This usually happens in the spring and fall of the year when outdoor temperatures are mild. These temperatures do not produce enough heat to warm the chimney up.

3. Chimney not tall enough. It must terminate at least 2 feet above the peak of the roof.

4. A downdraft can occur when the wind blows. This happens when your home is in a valley or high trees are near your home. Also, if your house is on the east side of a hill or mountain. One solution is to add a chimney cap with a weather vane. This often will turn a downdraft into an updraft. Another solution is to add height to your chimney. Another solution is to add a power ventor to the smoke pipe. The power ventor operates when the thermostat is calling for wood heat.

5. The barometric draft control must be set at .03.

If set less, the chimney may not draw. If set higher, the wood fire may draw too much combustion air. This causes the room temperature to exceed the thermostat setting.

OVER HEATING WHEN BURNING SOLID FUEL AS YOUR PRIMARY SOURCE OF HEAT

If your home is overheating, your furnace is providing heat when the thermostat is satisfied. One of these ideas will help with overheating.

1. The best answer is to use fewer logs at each filling. This provides the maximum amount of heat while conserving wood.

2. There are 3 pegs in the fan and limit control. One peg is set at 250º F. Never change this setting. The middle peg is set at 150º F. This is the temperature setting that the air circulating fan starts. You may want to set this setting at 160º F or higher. The bottom peg is set at 120º F. Reset this peg to 130º F or higher. These new settings will not allow the fan to run as much. This reduces the amount of air provided to the rooms.

NOTE: You will not have continuity of operation if you make adjustments to fan and limit control. This means that your air circulation blower may not operate continually when burning oil or gas.

3. You may feel that the furnace is oversized for your requirements. If this is the case cover part of the grate with a piece of heavy metal. This will retard the fire. This will cause some creosote buildup in firebox and chimney because it will not burn as clean.

GAS OR OIL PART OF FURNACE TOO LARGE FOR THE HOME

You or your furnace service provider may feel the furnace BTU input is too large or too high. This will cause the gas or oil blower to not operate continually when burning oil or gas. BTU input can be reduced to as little as 75,000 BTU input. Choosing this option will require adjusting the air circulation blower to a lower speed. This assures continuity of operation. Slowing the blower down will allow the blower to run continually. This occurs when the thermostat is calling for heat from the gas or oil burner.

IMPORTANT: During normal operation, firing door and ash drawer must be kept tightly closed. Air leakage will cause loss

of efficiency resulting in higher heating costs. If door gaskets become worn, replace with 1/2" fiberglass rope available from local sources.

NOTE: The damper will automatically close if there is

an electric power failure. This can occur from high limit cut-off or electrical power outage. This will prevent heat exchanger damage.
