Service and maintenance

1. To avoid electric shock, disconnect electrical supply before performing maintenance.

2. To avoid severe burns, allow furnace to cool before performing maintenance.

3. Perform service and maintenance as described in this manual and the burner manual.

4. Do not attempt to make adjustments to the blower or motor while the furnace is in operation. Disconnect power to the furnace and be sure all parts have stopped moving before attempting adjustments or maintenance.

5. The burner must be set up and adjusted using combustion test instruments. Visual examination of the flame alone cannot determine combustion performance.

Operation

6. Do not use the furnace as a construction heater.

7. Do not operate any furnace if the heat exchanger is damaged,

corroded or pitted. Toxic flue products could enter the air stream.

8. Do not jumper, attempt to by-pass or override any limit control.

9. Do not block flow of combustion or ventilation air to furnace. Do

not block or obstruct the air openings in the furnace casing.

10. Do not store or use combustible materials, gasoline, or other flammable liquids or vapors in the furnace area.

11. Do not operate the furnace if the furnace area will be exposed to air contaminants.

12. Should overheating occur, do not turn off or disconnect electrical supply to furnace. Instead, shut off the oil supply at a location external to the appliance, if possible.

13. Do not use this furnace if any part has been under water. Immediately call a qualified service technician to inspect the furnace and to replace any part of the furnace, control system or burner that has been under water.

14. Do not operate furnace if temperature rise through heat exchanger exceeds 85

NOTICE

Installation –

1. Be sure to level the furnace, using a spirit level on the front and one side. If the furnace is not level, oil can drip into the combustion chamber after burner cycling, causing fouling of the heat exchanger and the burner head.

2. Make sure all legs are in contact with the floor to distribute the load and prevent the possibility of undue noise or vibration.

Failure to adhere to the guidelines below can result in severe personal injury, death or substantial property damage.

Apply the following suggestions to prevent unsatisfactory operation of the furnace.

15. Inspect, clean and replace (if necessary) return air filter regularly.

16. Do not obstruct return air grills or supply air outlets.

17. Supply only #2 fuel oil to the burner. Never attempt to use

gasoline, a mixture of gasoline and oil, waste fuel, refuse or any other substance in the burner of furnace.

Installation

18. Do not block flow of combustion or ventilation air to furnace. Do not block or obstruct the air openings in the furnace casing.

19. Connect furnace only to a functional vent system in good condition. Place the furnace so as to allow proper venting, with the shortest possible venting and minimum number or elbows.

20. Always connect and seal a return air duct to the furnace unless the furnace is located in a large space, such as an unpartitioned basement. Route the return air duct to an adjacent room if no return air manifold is used.

21. Install furnace maintaining minimum clearances for service and separation from combustible surfaces described in this manual.

22. Install, start-up, service and maintain burner per instructions in this manual and the burner manual.

23. Verify burner is properly inserted through the combustion chamber opening.

24. Furnace must be installed so that burner and control system components are protected from dripping, spraying water or rain during operation or service.

25. If installing an air conditioning evaporator coil, install the coil downstream of, or in parallel with, the furnace to prevent condensation in the furnace heat exchanger. If the coil is in parallel, provide means to prevent flow of chilled air into the furnace, including an interlock to prevent simultaneous operation of heating and air conditioning.

3. Avoid locating return grills in rooms that may contain undesirable odors.

4. Never locate a return air grill closer than approximately 20 feet from the furnace.

5. Locate the furnac e near the center of the supply and return duct systems.

2 Prepare furnace and place in position

Inspect & prepare furnace

Remove furnace from carton

Remove the furnace from its shipping carton and inspect thoroughly. Remove access panels to inspect the furnace interior.

NOTICE

ARNIN

Immediately file a claim with the transportation company if you discover concealed damage.

Do not install or attempt to operate the furnace if the heat exchanger, burner or controls have been damaged. Immediately contact your furnace supplier. Operating a damaged furnace could result in severe personal injury, death or substantial property damage.

Prepare furnace (SCH models)

SCH furnaces require cutting the return air opening into one side of the furnace. Carefully cut the opening on the correct side of the furnace, using the four knock-outs on the side as guides.

Prepare burner

Remove the burner from its shipping carton and inspect thoroughly. Read the burner manual and follow instructions for preparing and installing the burner.

Install the correct nozzle for the required firing rate, using the burner manual and the information in Section 12 of this manual. Follow the burner manual instructions for nozzle installation. Verify the correct setting of electrodes after nozzle and burner oil tube assembly are in place.

Openings in walls, floor & ceiling

General

Ensure that the finished door opening to the furnace room is large enough to install and remove the furnace, water heater or any other appliances in the room.

Before placing furnace in a closet or small room, cut all openings required in floor, ceiling or walls for ducts and vent. This will simplify the work and prevent construction dust from entering the furnace heat exchanger.

ARNIN

Duct locations and sizing

Verify the size of the supply and return duct system is sufficient for the application. The pressure drop through the duct system must not exceed 0.25 inch water column. The total drop through the duct system and air conditioning evaporator coil (if used) must not exceed 0.5 inch water column.

Verify that all clearances to combustible construction and as needed for service accessibility will be met. The vent must be no closer than 3 inches to any combustible surface. Failure to comply could result in severe personal injury, death or substantial property damage.

Openings in walls, floor… (continued)

See suggested duct sizing in this manual. For more detailed sizing information refer to ACCA Manual D.

Return air duct

You must install a return air duct, sealed to the furnace, even if no return manifold is used. The only exception is when the furnace is located in a large unpartitioned room, such as a basement. (A room whose volume is at least 50 cubic feet per 1,000 BTU/h input of all appliances in the room is considered large). For large rooms, return air may be taken directly at the furnace, without a return air duct. No return air register should be within 20 feet of the furnace.

Cut the required opening for the return air duct in the wall (or floor or ceiling) of the room before placing the furnace.

Install filter

Install return air filter of the size listed in Section 12. You will need to install a filter rack provided with the furnace for

Model SCH only.

NOTICE

Verify that the filter will be easily accessible for removal after the furnace is in place.

Install furnace and burner

Place furnace

Place the furnace in the desired location. Measure clearances and verify per page 3 of this manual.

Using a spirit level on the front and one side of the furnace, level it using the 4 or 6 levelling legs. Make sure each of the legs is firmly in contact with the floor.

Inspect combustion chamber

Inspect the combustion chamber. Verify it is in good condition and correctly in position inside the heat exchanger. The burner opening in the chamber must align with the burner heat exchanger opening.

ARNIN

Insert burner

Following the burner manual instructions, install the burner and its gasket in the burner opening. Make sure the burner is aligned with the opening in the combustion chamber and that burner insertion corresponds to the value specified in Section 12.

Secure the burner in place with the three nuts and washers provided. Wire and pipe fuel to the burner per burner manual and this manual.

Burner orientation

Always keep the motor shaft in a horizontal position

The combustion chamber is constructed of ceramic fiber materials See the WARNING information on page 23 of this manual. Comply with these instructions when handling any ceramic fiber or fiberglass materials. Failure to adhere to these guidelines could result in severe personal injury or death.

Duct sizing

Determine air flow CFM

The temperature rise through the furnace must not exceed 85o F and should be at least 55°F for comfort. When calculating air flow, assume a temperature rise of 70°F.

The sensible heat temperature change for cooling would be approximately 27-30°F. Actual temperature change will be approximately 18-21°F due to humidity of the air.

To calculate the sensible heat temperature change (ΔT), you can use the formula:

ΔT = BTU/h/(1.1 x CFM) Eq. 3-1

To calculate air flow when you know temperature change (ΔT), you can use:

CFM = BTU/h/(1.1 x ΔT) Eq. 3-2

You can estimate air flow using the following rules of thumb:

Heating: 14 CFM per 1,000 BTU/h output Eq. 3-3 Cooling: 400 CFM per ton air conditioning Eq. 3-4

Determine the required air flow based on whichever is larger – heating mode or air conditioning mode.

Examples:

1. What would the temperature rise be for a 100,000 BTU/h output furnace with an air flow rate of 1200 CFM?

Use Equation 3-1 since you know CFM and BTU/h:

ΔT = 100,000/(1.1 x 1200) = 76°F

• The temperature rise would be 76°F.

• If the air enters the furnace at 70°F, it would leave the

furnace at 70°F + 76°F = 146°F.

2. What would the air flow be to obtain a 70°F rise through a 120,000 BTU/h output furnace?

Use equation 3-2 since you know ΔT and BTU/h: CFM = 120,000/(1.1 x 70) = 1,558 CFM

• The air flow would have to be 1,558 CFM to obtain a

temperature rise of 70°F.

3. Estimate the required air flo w for a 75,000 BTU/h output fu rnace installed with a 2-ton air conditioning evaporator coil.

Heating mode air flow (use Equation 3-3): CFM = 75 x 14 = 1,050 CFM Cooling mode air flow (use Equation 3-4): CFM = 2 x 400 = 800 CFM

• The larger number is 1,050 CFM (heating), so the duct

system should be sized for 1,050 CFM.

• The supply duct would need to be 16" round or a rectangular

equivalent such as 8" x 25" or 12" x 16", using Table 4, page

4. Estimate the required air flow for the same furnace installed with a 4-ton air conditioning evaporator coil.

Heating mode air flow is still 1,050 CFM. Cooling mode air flow (use Equation 3-4): CFM = 4 x 400 = 1,600 CFM

• The larger number is 1,600 CFM (cooling), so the duct

system should be sized for 1,600 CFM.

• The supply duct would need to be 18" round or a rectangular

equivalent such as 8" x 36" or 12" x 21", using Table 4, page

6 670-000-006-1007

CAUTIO

Always check the size of existing ducts, particularly if you are adding air conditioning. The air pressure loss through the cooling evaporator coil reduces available air flow. If the ducts are too small as well, the system may not work satisfactorily on either heating or cooling.

Determine duct dimensions

Table 4, page 7 and Table 5, page 8, provide typical round and rectangular duct sizes for rectangular and flat oval galvanized ducts. Do not apply these tables to size ductwork if the total equivalent length of the duct exceeds approximately 100 feet. For longer systems or for duct board, fiberglass-lined or flexible duct sizing, use the ACCA Manual D or the ACCA duct sizing slide rule. These tables are based on pressure loss of approximately 0.10 inch water column per 100 feet equivalent length of duct.

Use Table 3 below to size or check sizing of take-offs to supply registers or return grills.

Verify the size and type of registers, diffusers and grills from the manufacturer’s ratings. Do not exceed the recommended flow rate. The pressure drop allowance for each should not exceed approximately 0.05 inch water column.

Install a return air filter, sized per specifications in Section 12. Use only a return air filter mounted to the furnace. Do not add

additional filters unless the duct system is carefully sized to allow for the additional pressure drop.

4 Venting – Sealed Combustion System

ARNIN

Failure to follow all instructions can result in flue gas spillage and carbon monoxide emissions, causing severe personal injury or death.

The furnace can be side-wall vented without the use of a side-wall power vent, using a venting system with the high static pressure Beckett AFII and Riello 40-BF oil burners. Outdoor combustion air must be directly connected to the burner or the venting system will not function..

The notable characteristics of the vent system are as follows: a) Certified for use of the following materials for ducting the intake

air from the terminal to the burner: Schedule 40 PCV DWV, Schedule 40 ABS DWV and ASTM D-2729 sewer pipe;

b) One hole of minimal size (6 inches) is required to be cut into

the side-wall and the terminal is designed to fit through a minimum 2 x 8 joist space.

c) Incorporates a vent blockage safety shutdown system. If the

vent or intake opening ever becomes partially or fully blocked, the burner will shut down before a #1 smoke condition occurs;

d) The intake vent circuits within the terminal can be accessed for

cleaning.

There are three main components to the venting system:

- Vent terminal kit VTK-1 for the 105 series models or VTK-2 for the 160 series models.

- Flexible insulated venting material for IFV3 for the 105 series models or IFV4 for the 160 series models

- Field supplied 3 inch PVC or ABS intake piping.

ARNIN

Poisonous carbon monoxide gas hazard. Even though the flexible venting is insulated, it must

not run through an unheated space. To do so can cause residual condensation inside the

stainless steel liner, which may eventually perforate the liner and allow vent gases to enter the dwelling, which can result in personal injury and/or death or property damage.

Insulated flexible venting

The certified venting materials come in 3 lengths, Model # IFV3-15, IFV3-23 and IFV3-30 for the 105 model series or IFV4-15, IFV4-23 and IFV4-30 for the 160 model series, correspond to 15, 23 and 30 feet of continuous lengths of vent. The vent construction is coaxial and incorporates a stainless steel corrugated, flexible liner, surrounded by a thick insulation blanket and covered with an outer layer of flexible corrugated aluminum sleeve to protect the insulation. Splicing vent lengths together is prohibited. The maximum and minimum continuous vent lengths permitted for installation are:

5 feet minimum 30 feet maximum

Side-wall venting installation

ARNIN

Cut and abrasion hazard. Always wear protective gloves and eye protection

when handling the vent material. The process of cutting and fitting the flexible vent

material exposes the installer to sharp edges that can cause severe cuts to the skin.

670-000-006-1007

Connection to the furnace breach

1. Determine in which direction the venting will be routed from the furnace;

2. The flexible venting has 4 pieces of corrugated spi n sleeve that has been temporarily screwed over top of it. Remove the spin sleeve completely by unscrewing it in a counter-clockwise direction;

3. Using tin snips, cut the aluminium outer sleeve back by 5 inches on the IFV Series vent (see Figure 1.1). Ensure the snips are well adjusted and sharp or the cut end of the venting will be too jagged to start the threads of the spin sleeve (see Figure 1.1).

4. Prepare the furnace breach end of the insulated flex vent by first screwing the spin sleeve onto the corrugated aluminum jacket (see Figure 1.2) until the trailing edge of the spin sleeve is about 12 inches from the end of the vent (see Figure 1.3).

5. Pull the insulation back to expose the corrugated stainless steel core.

6. Cut the corrugat ed stainless steel core back by 3 inches on the IFV Series vent. You should now have about 3 inches of insulation hanging out past the stainless steel core (see Figure

1.4);

7. Push the stainless steel core onto the breach pipe as far as it will go (see Figure 1.5) and mechanically attach the vent to the breach using three of the #8 x 1/2" self-drilling screws provided with the VTK Series kit. The screws should be equally spaced around the circumference of the stainless steel core, starting with the first screw at top dead center. Start the drill point of the screws in the valleys of the corrugations at 3/8"-5/8" back from the end of the stainless steel core, so the screw heads can be properly sealed in the forthcoming operations (see Figure 1.6);

8. With the stainless steel core now firmly attached to the breach, apply sealant all around the joint, where the corrugated stainless steel core meets the smooth outer surface of the breach pipe (see Figure 1.7). In other words, the sealant must be centered over the joint;

9. Also, make sure that the heads of the self-drilling, stainless steel screws are completely covered with the sealant;

10. Two stainless steel band clamps are provided with the VTK Series kits. Position one stainless steel band clamp over the sealant, so that the edge of the clamp closest to the breach lines up with the sealant that is closest to the breach. Ensure that the band will close with an action of one strip sliding over the other - not under the gear head of the draw clamp (see Figure 1.8). Tighten the band clamp with considerable torque to cause the sealant to be squeezed into all crevices and to ooze out of the edge of the clamp closest to the breach (see Figure

1.9);

11. The seal is permanent and should never need to be broken, since the breach plate can be removed for cleaning and inspection using the 4-bolt joint;

12. Tuck the vent insulation into the breach collar;

13. Screw the spin sleeve tightly into the breach collar for a finished appearance. Wrap the other end of the spin sleeve with aluminum tape to cover any metal burrs that may be present (see Figure 1.10);

14. Bend the venting into the desired radius coming off the breach.

Connection to the vent terminal

1. Prepare the terminal end of the insulated flex vent b y first screwing the spin sleeve onto the corrugated aluminum jacket until the trailing edge of the spin sleeve is about 10 inches from the end of the vent;

2. Using sharp tin snips, cut the aluminum outer sleeve back

by 5 inches on the IFV Series vent;

3. Pull the insulation back to expose the corrugated stainless steel core;

4. Cut the corrugated stainless steel core back by 3 inches on the IFV Series vent. You should now have about 3 inches of insulation hanging out past the stainless steel core;

5. Push the stainless steel core onto the pipe on the back of the terminal as far as it will go and mechanically attach the vent to the terminal using three of the #8 x 1/2" self-drilling screws provided with the VTK Series kit. The screws should be equally spaced around the circumference of the stainless steel core, starting with the first screw at top dead center. Start the drill point of the screws in the valleys of the corrugations at 3/8"-5/8" back from the end of the stainless steel core;

6. With the stainless steel core now firmly attached to the terminal, apply sealant all around the joint where the corrugated stainless steel core meets the smooth outer surface of the breach pipe (see Figure 1.7). In other words, the sealant must be centered over the joint;

7. Also, make sure that the heads of the self-drilling, stainless steel screws are completely covered with the sealant;

8. Position the other stainless steel band clamp over the sealant so that the edge of the clamp closest to the terminal lines up with the edge of the sealant that is closest to the terminal. Tighten the band clamp with considerable torque to cause the sealant to be squeezed into all crevices and to ooze out of the end of the clamp closest to the terminal (see Figure 1.11);

9. The seal is permanent and should never need to be disconnected as the end of the terminal can be opened for cleaning and inspection by removing the screened end-cone assembly. Tuck the vent insulation into the recess in the terminal body;

10. Screw the spin sleeve tightly into the recess for a finished appearance. Wrap the other end of the spin sleeve with aluminum tape to cover any metal burrs that may be present (see Figure 1.12);

11. Bend the venting into the desired radius coming off the terminal.

Installing terminal in the wall

1. Cut a 6 inch hole in the side-wall in accordance with the location considerations outlined in the previous section;

2. Fasten the wall plate to the inside-wall using 4 field-provided fasteners, appropriate for the material behind the wall plate. Depending on the angle of access, the pressure control bracket may need to be removed to access the top right wall plate screw hole. For concrete and block, Tapcon™ screws or equivalent are recommended. Install the wall plate so that the top of the hole in the wall plate is positioned 1/8” lower than the top of the 6 inch hole in the wall. This will accommodate the proper downward slope of the terminal, in the direction from the inside to the outside;

10 670-000-006-1007

3. Remove the 2 screws fastening the end cone in place and remove the cone;

4. Remove the 2 screws fastening the stabilizer shroud in place and remove the stabilizer shroud;

5. Insert the main body of the terminal through the wall plate so that the end of the terminal extends about 2 inches past the outside wall;

6. Install the stabilizer shroud and replace the two mounting screws. (see Figure 1.13);

7. On concrete and block wall installations in particular, if it appears that the flange on the back of the stabilizer shroud is not large enough to cover the irregularities in the hole, a field fabricated wall plate can be constructed out of 304, 316, or 316L stainless steel;

8. Silicone seal the circumference of the joint where the stabilizer shroud connects to the main body of the terminal;

9. Apply caulking to the back plate of the stabilizer shroud and push the terminal back firmly against the wall, making sure the pressure switch is located at the top, in a horizontal position;

10. While pushing down gently on the top of the stabiliser shroud, install the 3 stainless steel 2 inches screws provided with the kit to secure the back of the shroud to the wall. Do not overtighten the screws or it will distort the stabiliser shroud. The screws will not be necessary in a concrete or block wall as the mortar can provide positive positioning;

11. Tighten the clamp on the wall plate to secure the terminal in place;

12. Apply more caulking all around the seam where the stabilizer shroud meets the wall. It is important to have a good seal to prevent water from entering the dwelling (see Figure 1.14). A considerable amount of caulking may be necessary for irregular wall surfaces such as lapped siding;

13. Install the end cone and replace the two mounting screws;

14. Support the vent and intake air piping so that a 1/4" to 1/2" downward slope (toward the outside) results for proper drainage out the terminal body.

Ducted outdoor combustion air (Sealed Combustion System)

The burners are set up to duct outside combustion air directly to the burner: the Beckett AFII and the Riello 40-BF for side-wall venting.

CAUTIO

The venting system is a sealed system and completely isolates the furnace from the interior of the building. The burner is totally unaffected by any pressure fluctuations within the building makes it ideal for tight home construction.

The use of ducted outside combustion air is mandatory with side-wall venting systems. The system operates on a balanced flue principle and will not function properly if the combustion piping is not attached and sealed at all connections between the vent terminal and burner inlet.

which

SCH & SCL Oil Furnaces – Furnace Manual

4 Venting – Sealed Combustion System (continued)

The venting system requires additional parts, which are not included with the kit. These parts must be constructed of 3 inch Schedule 40 PVC, PVC-SWV, 26-SDR, SDSR-21, Septic Sewer Pipe or ABS plastic pipe, fittings and sealant. Also, installation procedures, piping and fittings must conform to the following ANSI/ASTM standards:

PVC ASTM D-1785 SDR-26, SDR-21 ASTM D-2241 Septic Sewer Pipe ASTM D-2729 PVC-DWV ASTM D-2665 PVC Primer and Solvent Cement ASTM D-2564 ABS Pipe and Fittings ASTM D-2235 Procedure for Cementing Joints ASTM D-2855

Additional parts required (not included in VTK kit) a. 3 inch elbow fitting as required;

b. 3 inch plastic pipe; c. 3 inch 90° elbow, female-female (for terminal); d. 3 inch female to 2 inch female reducer (Riello 40-BF burner

only);

e. 2 inch 90° elbow, street t ype, female-male (Riello 40-BF burner

only);

f. 3 inch female-female PVC or ABS coupling, not sewer pipe

(Beckett AFII burner only);

g. Transition bushings to go from PVC or ABS to ASTMD-2279

Septic Sewer Pipe (if applicable).

If PVC fittings are mixed with ABS fittings, use solvent cement that is approved for bonding the two plastics.

Intake pipe length

The venting system has been certified for 120 equivalent feet o f 3 inch intake pipe. Count a 90° elbow as 10 equivalent feet and a 45° elbow as 5 equivalent feet in the calculation.

For example: 1 length of 5 feet = 5 equivalent feet

2 lengths of 10 feet = 20 equivalent feet 3 elbows, 90° = 30 equivalent feet 2 elbows, 45° = 10 equivalent feet 1 elbow, 90° (terminal) = 10 equivalent feet 1 elbow, 90° (Riello burner)

Total: = 85 equivalent feet, which is less than 120 feet and therefore acceptable.

Intake pipe installation

Obtain the necessary additional parts, to complete the installation and start by piping at the burner. If the optional vestibule was installed, remove the appropriate knockouts in the side panels of the vestibule. The lower 5 inch knock outs in the right-hand panel is used for the Beckett AFII burner. The higher 5 inch knockouts on the right and left-hand panels are for right or left connection to the Riello 40-BF burner.

= 10 equivalent feet

Beckett AFII burner

Remove the burner intake cover by removing 3 screws securing it in place. Discard the cover and screws. Apply silicone liberally around the end of a 3 inch coupling and fully insert the siliconed end into the burner opening. Fasten securely with 3 self-tapping sheet metal screws.

Riello 40-BF burner

Fully insert the female end of the 2 inch, 90° street elbow into the combustion air fitting on top of the burner. Fasten securely with 3 self-tapping sheet metal screws. Cement the 2 inch end of the 3 inch female to 2 inch female reducer into the male end if the 2 inch 90° street elbow. If the parts are not easily obtained, use a 3 inch 90° street elbow with the male end fitted over the combustion air fitting. The fitting will have to be silicone sealed, as the fit will be a bit loose. Fasten securely with 3 self-tapping sheet metal screws.

Terminal connection

Insert the 3 inch 90° female-female elbow onto the stainless steel air intake fitting located on the right side of the vent terminal (viewed from the rear). Fasten with 3 self-tapping sheet metal screws.

Intermediate piping

Pipe as required between the terminal and the burner. Ensure that the 3 inch piping is routed and supported in accordance with local and national codes. Obey minimum furnace clearances to combustibles when routing any section of 3 inch piping in the vicinity of the furnace. If Septic Sewer Pipe is to be used, install transition bushings at the 3 inch female ends of the fittings at the burner and at the terminal. Transition bushings are readily available and are required because 3 inch PVC and ABS pipes have a typical outside diameter of 3.5 inches, whereas Septic Sewer Pipe has a typical outside diameter of 3.25 inches.

Equipment.

• In Canada, CSA B139, Installation of Oil-Burning

Equipment.

• Local codes and regulations.

• Information provided with burner and fuel pump.

• If an y part of fuel oil tank is above level of burner, an anti-

siphon device must be used to prevent flow of oil in case of oil line break.

• Support oil lines as required by codes.

• Make tank connections with swing joints or copper tubing to

prevent breaking in case the tank settles. Make swing joints so they will tighten as tank settles. Non-hardening pipe joint compounds should be used on all threads.

ARNIN

• Underground pipe must be run in a casing to prevent oil leaking into ground or under floor. Check local codes for information.

Oil piping connection at burner

• Connect oil line to burner using a flare fitting.

ARNIN

• See local codes for appropriate arrangement and piping of filter, control valves, etc. connecting to oil tank.

• Refer to burner manual for oil system requirements. Verify that suction lift does not exceed stated limit. Where lift exceeds limit for a one-pipe system, use a two-pipe system as directed in burner manual.

ARNIN

Do not use Teflon tape as an oil pipe sealant. It can cause valves to fail, creating hazards. Use only flare fittings. Do not use compression fittings. Failure to comply could result in severe personal injury, death or substantial property damage from oil leakage and/or fire hazard.

Use of any connection other than a flare fitting at the oil connection to the burner could result in a fuel oil leak, with the potential for severe personal injury, death or substantial property damage.

Electric shock hazard. Can cause severe personal injury or death if power source, including service switch on furnace, is not disconnected before installing or servicing.

The burner harness is factory-wired to the furnace at the factory. Plug the burner harness into the mating burner connector to wire the burner. Refer to the wiring diagram on pages 16 and 17 for further information.

Install and wire thermostat / shut-off system

Mount the room thermostat on an interior wall in the natural circulating path of room air. Do not locate the thermostat so it is exposed to cold air infiltration, drafts from windows or doors, air currents from supply or return air registers, behind obstructions, on a shelf, in a closet, or in a corner.

Ensure that the thermostat will not be exposed to heat from a nearby fireplace, radio, television, lamp or rays from the sun. Do not mount the thermostat on a wall over a supply or return duct, chimney or vent.

Wire thermostat to the vent terminal pressure switch and to the furnace electrical box (refer to wiring diagram). Set thermostat anticipator as shown on wiring diagrams on pages 16 and 17.

Connect power wiring

All wiring must conform to:

• National Electrical Code, ANSI/NFPA 70, latest edition and any additional national, state or local codes.

• In Canada, CSA C22.1 Canadian Electrical Code Part On e and any local codes.

• Wiring must be N.E.C. Class 1. If original wire as supplied with furnace must be replaced, type 105° C wire or equivalent must be used. Supply wiring to furnace must be sized for the load required (see Section 12).

• Provide electrical ground at furnace as required by codes.

Connect 120 VAC/60 Hertz, single phase separate electrical line from the main house panel to the power leads in the furnace electrical box as shown on wiring diagram, pages 12, 13, 14 and

15. Provide a fused disconnect in the power wiring, following all

local codes. Ensure the wire size and type are adequate for the electrical load

(see Section 12 and furnace nameplate for value).

Limit control

The furnace is equipped with a fan switch/limit control. This control limits the air leaving the heat exchanger to 200° F or less. The fan switch continues fan operation until the air drops to a preset temperature. For most installations, set the blower ON setting at 110° F and blower OFF setting at 90° F. If a longer cool down period is desired, lower the OFF setting.

10 Service and maintenance (continued)

Service/maintenance procedures

To inspect blower motor

Belt-drive motor – Blower bearings and the motor are permanently lubricated and do not require oiling. Verify that the blower, motor pulleys and belt are in good condition. Replace if necessary.

Direct-drive motor – Blower bearings and the motor are permanently lubricated and do not require oiling.

Clean blower wheel – Vacuum dust from blower wheel blades and surrounding area.

To clean heat exchanger

ARNIN

1. Remove the burner.

2. Inspect the heat exchanger using a mirror inserted through the burner opening.

3. Usi ng a brush on a fle xible handle, loosen the soot on the inside of the heat exchanger.

4. Remove the soot with a vacuum. Be careful not to damage the combustion chamber while cleaning the heat exchanger.

5. Open the heat exchanger cleanout cover, if present. Using a brush on a flexible handle, loosen the soot from the heat exchanger surfaces. Remove as much soot as possible using a vacuum.

6. Close cleanout cover.

7. Inspect combustion chamber and replace with a new one if chamber is damaged in any way.

8. Re-install burner.

ARNIN

Inspect vent system

Thoroughly inspect the entire vent system at least annually. Ensure vent system is repaired or replaced if necessary before placing furnace in operation.

Oiled-bearing burner motors

The burner may need to be lubricated if motor is equipped with oiling cups. Refer to burner manual for specific instructions. If instructed, apply a few drops only of S.A.E. 20 detergent oil (never use household oils). Do not attempt to “fill up” the oil cup. Over-oiling can damage the motor.

24 670-000-006-1007

The heat exchanger must be cleaned and/or inspected at least once each year. Operating the furnace with a fouled or leaking heat exchanger could result in severe personal injury, death or substantial property damage.

The combustion chamber contains ceramic fiber materials. Wear a NIOSH-approved respirator while cleaning the furnace and follow WARNING on page 20 for proper handling.

Obtain gas-tight seal at burner flange and cleanout plates to prevent possible flue gas leakage and carbon monoxide emissions, leading to severe personal injury or death.

Annual start up

DANGE

Follow information below to prevent severe personal injury, death or substantial property damage:

• Do not use gasoli ne, crankcase drainings or any oil

containing gasoline. See burner manual for proper fuel oil.

• Do not attempt to start burner when excess oil has

accumulated, when unit is full or vapor or when combustion chamber is very hot.

• Do not start burner unl ess vent and burner mounti ng

plate are secured in place.

• Never burn garbage or paper in the furnace.

• Never leave combustible material around it.

To start furnace

1. Factory burner adjustment and settings may not be suitable for specific job conditions. Refer to burner manual as well as the “Dimensions and Ratings” section of this manual for burner start up, adjustment and checkout procedures.

2. Set room thermostat to call for heat.

3. Refer to burner manual for start up.

4. The furnace blower will delay for a short after burner starts, until the limit/fan switch senses air temperature above the fan ON setting.

5. Set room thermostat to its lowest setting. Burner should turn off.

6. Furnace blower will continue to run until the limit/fan switch senses air temperature below the fan OFF setting.

7. Set the room thermostat to call for heat again. Allow furnace to heat to design temperature. Then adjust burner for correct combustion, using combustion test equipment. Adjust burner for:

: between 10 % and 11 ½ %, with 0 smoke.

8. Take an overfire pressure reading (refer to Section 7)

ARNIN

8. Check furnace and duct system for proper operation and conditions.

9. Inspect vent system for proper operation.

10. To set limit/fan switch: The blower operates until the air temperature drops below the

fan OFF setting. If the air at the supply registers is too warm at blower start up or shutdown, lower the fan OFF and ON settings on the limit/fan switch.

11. Complete testing of the burner cad cell control using the instructions in the burner manual.

Make final burner adjustments using combustion test equipment to assure proper operation.
