1.2.1) Safety Rules

Your unit is built to provide many years of safe and dependable service, providing it is properly installed and maintained. However, abuse and/or improper use can shorten the life of the unit and create hazards for you, the owner.

a. The U.S. Consumer Product Safety Commission recommends

that users of oil or gas-burning appliances install carbon monoxide detectors. Carbon monoxide can cause serious injury and/or death. Therefore, to help alert people of potentially dangerous carbon monoxide levels, you should have carbon monoxide detectors, listed by a nationally recognized agency (e.g. Underwriters Laboratories or International Approval Services) and maintained in the building or dwelling (see Note below).

b. There can be numerous sources of fire or smoke in a building or

dwelling. Fire or smoke can cause death, serious bodily injury and/or property damage. Therefore, in order to alert people of potentially dangerous fire or smoke, you should have fire and smoke detectors installed (listed by Underwriters Laboratories) and maintained in the building or dwelling (see Note below).

NOTE: The manufacturer of your furnace does not test any detectors

and makes no representations regarding any brand or type of detector.

CAUTION

Ensure that the area around the combustion air intake terminal is free of snow, ice and debris.

CAUTION

Do not use any commercially available soot remover. This furnace has a fibre type refractory combustion chamber. Normal servicing of this unit does not require cleaning of the combustion chamber. Use extreme care if for any reason you have to work in the area of the combustion chamber.

1.2.2) Freezing temperatures and your building

WARNING

Freezing temperature warning. Turn off water supply. If your heater remains shut off during cold weather

the water pipes could freeze and burst, resulting in serious water damage.

Your unit is equipped with safety devices that may keep it from operating if sensors detect abnormal conditions such as clogged exhaust flues.

If the structure is unattended during cold weather you should take the following precautions:

a. Turn off main water supply into the structure and drain the water

lines if possible. Open faucets in appropriate areas;

b. Have someone check the structure frequently during cold

weather to make sure it is warm enough to prevent pipes from freezing. Contact a qualified service agency, if required.

1.2.3) Installation regulations

All local and national code requirements governing the installation of oil burning equipment, wiring and flue connections MUST be followed. Some of the codes that may be applicable are:

1.5) AIR FOR COMBUSTION

WARNING

Poisonous carbon monoxide gas hazard. Comply with ANSI/NFPA (in the U.S.A.) or CSA (in

Canada) standards for the installation of Oil Burning Equipment and applicable provisions of local building codes to provide combustion and ventilation air.

Failure to provide adequate combustion and ventilation air can result in death and/or personal injury.

1.5.1) General

Oil furnaces must have an adequate supply of combustion air. It is common practice to assume that older homes have sufficient infiltration to accommodate the combustion air requirement for the furnace. However, home improvements such as new windows, and weather stripping have drastically reduced the volume of air infiltration into the home.

Home air exhausters are common. Bathroom and kitchen fans, power vented clothes dryers, and water heaters all tend to create negative pressure in the home. Should this occur, the chimney becomes less and less effective and can easily downdraft.

Heat Recovery Ventilation (HRV) systems are gaining in popularity. HRVs are not designed to supply combustion air. If not properly balanced, a serious negative pressure condition could develop in the dwelling.

1.5.2) Contaminated Combustion Air

Installation in certain areas or types of structures will increase the exposure to chemicals or halogens which may harm the furnace. These instances will require that only outside air be used for combustion.

The following areas or types of structures may contain or have exposure to the substances listed below. The installation must be carefully evaluated, as it may be necessary to provide outside air for combustion.

a. Commercial buildings; b. Buildings with indoor pools; c. Furnaces installed near chemical storage areas.

doors,

Exposure to these substances:

445 01 4054 06

a. Permanent wave chemicals for hair;

b. Chlorinated waxes and cleaners;

c. Chlorine based swimming pool chemicals;

d. Water softening chemicals;

e. De-icing salts or chemicals;

f. Carbon tetrachloride;

g. Halogen type refrigerants;

h. Cleaning solvents (such as perchloroethylene);

i. Printing inks, paint removers, varnishes, etc.;

j. Hydrochloric acid;

k. Solvent based glue;

l. Antistatic fabric softeners for clothes dryers;

m. Acid based masonry cleaning materials.

1.5.3) Ducted outdoor combustion air

Outdoor combustion air kit – chimney venting

The following kits have been certified for use with the appliance. The

component kits contain an important safety feature, namely a Vacuum

Relief Valve or VRV. During normal operation the burner aspirates

outdoor air. If the intake terminal ever becomes partially or fully

blocked from ice or snow etc., the VRV will open to allow a proportion

of air from the dwelling to enter the burner, thus maintaining proper

combustion. Once the blockage is removed, the VRV will close and

the burner will draw all the air from the outside again:

CAS-2B

Components for the Beckett AFG burner (except air duct): The kit

includes the intake terminal, vacuum relief valve (VRV) and

boot connection with integral air adjustment means for the

burner. The CAS-2B can be used with a 10 cm (4") galvanized air duct

or a 10 cm (4") flexible aluminium air duct. It is recommended that the

metallic air ducting material be insulated from the air intake up to

1.5 m (5') from the burner to avoid condensation from forming on the

outside of the intake pipe.

CAD-1

Air duct kit consists of 7.6 m (25') of insulated UL/ULC Listed Class 1

air duct, and two 10 cm (4") steel band clamps. The duct incorporates

a corrugated flexible aluminium core, surrounded by fibreglass

insulation covered with a vinyl vapour barrier.

special air

AFG

CAUTION

The CAS-2B does not turn the furnace installation into a

direct vent system. Therefore the building structure

must provide for adequate combustion air to be

delivered to the Vacuum Relief Valve. The burner will

need to draw combustion air from the VRV’s

surroundings if the intake ever becomes blocked.

Therefore, non-direct vent installation codes must be

followed.

Comprehensive installation instructions are provided with the kits.

1.6) OIL TANKS AND LINES

Check your local codes for the installation of the tank and accessories.

A manual shut-off valve and an oil filter shall be installed in sequence

from tank to burner. Be sure that the oil line is clean before connecting

to the burner. The oil line should be protected to eliminate any

possible damage. Installations where the fuel oil tank is below the

burner level must employ a two pipe fuel supply system with an

appropriate fuel pump. A rise of more than 2.4 m (8') requires a 2

stage pump and more than 4.9 m (16') an auxiliary pump.

Follow the pump instructions to determine the size of tubing you need in relation to the rise, or to the horizontal distance.

Inspect the entire oil distribution system for leaks at the beginning of each annual heating season.

1.7) BURNER INSTALLATION

FIGURE 2

CAUTION

Do not turn on the burner until you have checked the polarity.

Checking the polarity

445 01 4054 06

The oil burners used on the furnaces have solid state control systems that make them sensitive to the proper connections of the hot and neutral power lines. The controls will be damaged if the two lines are reversed.

1. Set your voltmeter to line voltage;

2. Place one prong on your grounded electric entry box and one

prong on the black wire;

3. Read the voltage;

4. If the voltage is zero, check the white wire. If line voltage shows.

Reverse the 115-volt leads entering the furnace junction box;

5. If you do not have a voltmeter, use a pilot light.

DNS-0864 Rev. A

Checking the Nozzle

The burner is equipped with the appropriate nozzle. However, if another size or a replacement nozzle is required, use the manufacturer’s recommended spray angle and type as shown in Tables 3.1 to 3.4, p. 15 to 18. Note that all nozzle sizes are based on a pump pressure of 100 psi.

Always select nozzle sizes by working back from the desired flow rate at operating pressure, and not the nozzle marking.

Checking air and turbulator settings

Before starting the burner for the first time, adjust the air and turbulator settings to those listed in the Tables 3.1 to 3.4, p. 15 to 18. Once the burner becomes operational, final adjustment will be necessary.

Checking the fuel supply system

Fuel Specifications

NOTE: Use No.1 or No. 2 Heating Oil (ASTM D396) or in Canada use No.1 or No. 2 Furnace Oil.

Before starting the burner, be sure that the fuel tank is filled with clean oil.

FIGURE 2.1

IMPORTANT

When using nozzle sizes of less than 0.75 USGPH, the Installation Code for oil burning equipment requires the installation of a 10 micron (or finer) filter in the fuel oil line. ICP requires that this practice be followed in order to keep the lifetime heat exchanger warranty intact.

WARNING

Fire and explosion hazard. Use only approved heating type oil in this furnace.

DO NOT USE waste oil, used motor oil, gasoline or kerosene.

Use of these will result in property damage injury or death.

NOTE: You may notice a slight odour the first time your furnace is

operated. This will soon disappear. It is only the oil used on certain parts during manufacturing.

1.8) BLOCKED VENT SHUT-OFF (BVSO) For chimney venting

WARNING

It is imperative that this device be installed by a qualified agency.

This device is designed to detect the insufficient evacuation of combustion gases in the event of a vent blockage. In such a case the thermal switch will shut down the oil burner. to be restarted MANUALLY.

CAUTION

A positive pressure venting system (Sealed Combustion System or Direct Vent) MUST NOT use the BVSO. Follow the instructions supplied with the venting system.

1.9) INSTALLING ACCESSORIES

WARNING

Electrical shock hazard. Turn OFF electric power at fuse box or service

panel before making any electrical connections and ensure a proper ground connection is made before connecting line voltage.

Failure to do so could result in bodily injury or death, property damage.

1.9.1) Air conditioning

Wire the thermostat and condensing unit contactor as indicated in the wiring diagram in Figure 5, p. 21.

supply air side only.

1.9.2) Ductwork and Filter

Installation

Design and install the air distribution system to comply with Air Conditioning Contractors of America manuals or other approved methods that conform to local codes and good trade practices. When ducting supplies air to a space other than where the furnace is located, the return-air ducts must be sealed and also be directed to the space other than where the furnace is located.

Install the air conditioning cooling coil (evaporator) downstream from the supply air plenum of the furnace. If a separate evaporator and blower unit is used, install appropriate sealing dampers for air flow control. Cold air from the evaporator coil going through the furnace could cause condensation and shorten furnace life.

CAUTION

Dampers (purchased locally) MUST be automatic.

WARNING

Poisonous carbon monoxide gas hazard. Do NOT draw return air from inside a closet or

utility room. Return air duct MUST be sealed to furnace casing.

Failure to properly seal ducts can result in death, personal injury and/or property damage.

WARNING

Poisonous carbon monoxide gas hazard. Install evaporator coil on the supply side of the

furnace ducting. Evaporator coil installed in return side ducting can

cause condensation to form inside heat exchanger resulting in heat exchanger failure. This could result in death, personal injury and/or property damage.

2.2) CHECKS AND ADJUSTMENTS

2.2.1) General

After initial installation and subsequent yearly maintenance calls, the furnace must be thoroughly tested.

The burner must be functioning for at least 10 minutes before any test readings are taken. Adjustments are to be made according to the Technical Specifications in this manual.

Open the oil bleed port screw and start the burner. Allow the oil to drain into a container for at least 10 seconds. Once the oil flows absolutely free of white streaks or air bubbles to indicate that no air is being drawn into the suction side of the oil piping and pump, slowly close and tighten the bleed screw. The burner should now fire. Adjust the oil pressure as indicated in the Technical Specification Tables 3.1 to 3.4, p. 15 to 18.

PART 2

CAUTION

Do not attempt to start the burner when excess oil has accumulated, when the furnace is full of vapour, or when the combustion chamber is very hot.

2.2.3) BVSO Performance Test

The purpose of the following test is to check that the electrical outlet on the furnace, designated to the BVSO, is functional.

1. Start up the burner;

2. Remove the three-pole plug from the BVSO outlet on the

furnace;

3. The burner must shut-off immediately, while the blower continues

to run to the end of the cool-down cycle.

If the test is not in line with the above, CALL A QUALIFIED SERVICE TECHNICIAN.

2.2.4) Combustion chamber curing

Some moisture and binders remain in the ceramic combustion chamber after manufacture. It is important to clear the chamber of this residue before testing. If you smoke test before curing, the instrument may become damaged. To cure the chamber, run the unit for 3 consecutive cycles, with 3 minutes of elapsed time in between each cycle. Each burn cycle should least 3 minutes. The exhaust will have a pungent odour and produce a white cloud of steam.

2.2.5) Smoke / CO2 test

1. Pierce a test hole in the smoke pipe near the furnace breech.

Insert the smoke test instrument probe into the open hole;

2. Starting with a zero smoke reading, gradually reduce the burner

air setting until just a trace of smoke results (#1 on Bacharach Scale);

3. Take a CO

2.2.6) Supply air temperature rise test

1. Operate the burner for at least 10 minutes;

2. Measure the air temperature in the return air plenum;

3. Measure the air temperature in the largest trunk coming off the

supply air plenum, just outside the range of radiant heat coming off the heat exchanger; 0.3 m (12") from the plenum on the main take-off usually sufficient;

4. The temperature rise is calculated by subtracting the return air

temperature from the supply air temperature;

5. If the temperature rise exceeds the temperature specified in

Tables 3.1 to 3.4, p. 15 to 18, change to the next higher blower speed tap until the temperature rise falls to this temperature or below. If the excessive temperature rise cannot be reduced by increasing fan speed, investigate for ductwork restriction(s), dirty or improper air filter, overfiring caused by excessive pump pressure, or improper nozzle sizing.
