The signal word CAUTION is used throughout this manual in the following manner:

NOTE: It is the personal responsibility and obligation of

the customer to contact a qualified installer to ensure that the installation is adequate and conforms to governing codes and ordinances.

Fire hazard

The furnace must be installed in a level

position, never where it will slope to the

front.

If the furnace were installed in that position, oil could drain into the furnace

vestibule and create a fire hazard, instead of draining properly into the combustion

chamber.

a. This furnace is NOT approved for installation in

mobile homes, trailers or recreation vehicles.

b. You must have a sufficient supply of fresh air for

combustion and ventilation to the area in which the

furnace is located.

c. Do NOT use this furnace as a construction heater

or to heat a building that is under construction.

d. Use only the Type of fuel oil approved for this

furnace (see Rating Plate on unit). Overfiring will

result in failure of heat exchanger and cause dangerous operation.

e. Visually check all oil line joints for signs of wetness,

which would indicate a leak.

f. Connect furnace to a side-wall terminal or chimney. g. The points in Part 2 "Operation" are vital to the

proper and safe operation of the heating system. Take the time to be sure they are all done.

h. Follow the rules of the NFPA Pamphlet No.31 (for

USA) and B-139 (for Canada) or local codes for locating and installing the oil storage tank.

i. Follow a regular service and maintenance schedule

for efficient and safe operation.

j. Before servicing, allow furnace to cool. Always shut

off electricity and fuel to furnace when servicing. This will prevent electrical shock or burns.

k. Seal supply and return air ducts. I. The vent system MUST be checked to determine

that it is the correct type and size. m. Install correct filter type and size. n. Unit MUST be installed so electrical components

are protected from direct contact with water.

2.1) Safety Rules:

potentially dangerous fire or smoke, you should have fire and smoke detectors listed by

Underwriters Laboratories installed 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

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

CAUTION

The air pressure switch MUST be used when the furnace is vented by the side-wall.

CAUTION

Do not use any commercially available soot remover. This furnace has fiber type

refractory combustion chamber. Normal servicing of this unit does not require cleanings of the combustion chamber. Use extreme care if for any reason you have to

work in the area of the combustion chamber.

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-burning appliances install carbon monoxide detectors. There can be

various sources of carbon monoxide in a building or dwelling. The sources could be gas-fired clothes

dryers, gas cooking stoves, water heaters,

furnaces, gas-fired fireplaces, wood fireplaces, and

several other items. Carbon monoxide can cause serious bodily 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 recognised agency (e.g. Underwriters Laboratories or International

Approval Services) installed and maintained in the

building or dwelling (see Note).

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

a building or dwelling. Fire or smoke can cause serious bodily injury, death, and/or property

damage. Therefore, in order to alert people of

2.2) Freezing Temperatures and Your

4) VENTING

4.1) General:

The furnaces can be vented in several ways:

Chimney Vented:

Using the Beckett AFG or Riello 40-F burner, the furnaces can be chimney vented with or without a

barometric damper. The unit will be operated at a

negative over fire draft and stack draft.

Poison carbon monoxide gas, fire and explosion hazard.

Read and follow all instructions in this section.

result in property damage, personal injury

I Failure to properly vent this furnace can I

and/or death,

Side-wall Vented:

Additionally, the liner must be insulated according to the insulating procedure recommended by the

manufacturer of the liner.

Using the Beckett AFII or Riello 40-BF burner with the integral pre and post purge controls, the system can be

side-wall vented with the new DV-2000 TM venting system for maximum efficiency, and without the use of a

side-wall power ventor. The unit will be operated at a

positive overfire draft and stack draft.

Poison carbon monoxide gas hazard

Never co-vent the furnace with another combustion appliance when side-wall

venting.

To do so may result in asphyxiation and death to the occupants

4.2) Chimney installations:

The oil furnaces, when set up for chimney venting, are certified for use with L-vent, A-vent, tile-lined and metal-

liner-tile-lined chimneys, and can be vented both with and without a barometric draft damper. However, the

furnace has not been certified without the barometric damper when it is to be co-vented with another oil-fired

appliance, such as a water heater.

When a damper is used, the basement air entering the damper reduces the possibility of vent condensation. However, if the barometric damper is not used, a

chimney liner with insulation must be employed.

With a barometric damper:

Poison carbon monoxide gas hazard

Never install a hand operated damper in the vent pipe. However, any Underwriters

Laboratories listed electrically operated automatic type vent damper may be

installed if desired. Be sure to follow

instructions provided with vent damper.

Read and follow all instructions in this section.

Failure to properly vent this furnace or other appliances can result in property

damage, personal injury and/or death.

Vent connectors:

For installations without barometric damper, the vent connector should be as short as possible and either be of double wall construction, or be of single wall construction insulated with 1" of insulation, tt should

rise a minimum of 1/4" per foot from the furnace to the chimney. Field fabricated connectors should be a minimum of 28 gauge. The joints must be mechanically

secure and there must be no flue product leakage at the

joints.

CAUTION

When the furnace (chimney installation) is co- vented with other combustion appliances such

as a water heater, the allowable venting

materials (i.e. L-Vent etc.) for use with those appliances should also be investigated.

The appliance may be installed in a chimney of the proper size and adequate chimney base temperature as

specified in the Installation Code. The relevant excerpt from the code is found in this section - Use it as a guide

when local or national codes do not exist.

Without a barometric damper:

Due to the lack of dilution air that would ordinarily be drawn into the barometric damper, the dew point of the

flue gasses is raised. To offset the increased tendency for vent condensation, the chimney must be lined.

Flue pipe sizing:

The following table is an except from the installation code and indicates permitted flue sizes and minimum

base temperatures for circular flues in chimney with thermal resistance less than R6 (6 ft2 ohr o°F / Btu). Where a new appliance, burner, or chimney is installed, chimney vent sizes and maximum flue-gas

temperatures (measured at the chimney connector with the barometric damper shut, after 5 minutes of

operation) shall comply with the table #2.

Applying the Table:

J Notes: Thermal resistance values for typical chimneysare as follows:

resistance of this chimney type is R2, which is less than

R6. The actual firing rate at 156 psig is 1.25 x .60 = .75. Therefore this table shall apply as:

The minimum size permitted shall be 4 in. inside diameter.

The maximum size permitted shall be 5 in. inside diameter.

The minimum base temperature shall be about 320°F.

4.3) Side-wall venting, DV-2000 TM Direct Vent System:

The furnace can be side-wall vented without the use of a side-wall power ventor using the new DV-2000 TM

venting system with the high static pressure Beckett AFtt and Riello 40-BF oil burners. Outdoor

combustion air must be directly connected to the burner of the DV-2000 TM venting system will not

function.

The notable characteristics of the DV-2000 TM system are as follows:

Certified to use the following materials for ducting the intake air from the terminal to the burner; Schedule 40 PVC DWV, Schedule 40 ABS DWV, And ASTM 2729

Sewer Pipe.

One hole of minimal size (6") is required to be cut in the side-wall, and the terminal is designed to fit through a

minimum 2 X 8-joist space.

The standard terminal is designed for a wall thickness up to 14", and the deep wall terminal for wall thickness

up to 25".

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 #_! smoke occurs.

The intake and vent circuits within the terminal can be accessed for cleaning.

There are 3 main components to the DV-2000 TM system; the VTK vent terminal kit, the IFV insulated

flexible venting material and the field-supplied 3" PVC or ABS intake piping.

Vent terminal kits - DV-2000TM:

The certified standard vent terminal kit is Model No. VTK-1 or VTK-2, and is suitable for installation in walls up to 14" thick. An alternate kit, Model VTK-1-DW or VTK-2-DW is available to accommodate walls up to 25"

thick. Both kits contain the following items to complete the hook-up to the venting and furnace:

1 Terminal

2 Sealing Clamps

1 Side-wall Venting Breech Plate

2 Sealing Strips

1 Inner Wall Plate 1 Pressure Control with Tubing

2 Insulated Quick-connect Terminals

3 StainlessSteelScrews 6 Selftappingstainlesssteelscrews

Insulated flexible venting - DV-2000TM:

The certified venting materials come in 3 lengths, Model No. tFV3-15, IFV3-23 and IFV3-30 (or IFV4-15, IFV4-23

and IFV4-30 for 160 models) are corresponding to 15', 23' and 30' 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 aluminium 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

Poison carbon monoxide gas hazard

c. within 6 feet of a window or door, or mechanical air

supply inlet to any building, including soffit openings;

d. above a gas meter/regulator assembly within 3 feet

of a vertical centerline of the regulator;

e. within 6 feet of any gas service regulator vent

outlet, or within 3feet of an oil tank vent, or an oil fill inlet;

f. within less than 1 foot above ground level; g. 6 feet of any other combustion air inlet;

h. within 6 feet of a property line; i. underneath a veranda, porch or deck;

j. so that the flue gases are directed at combustible

material or any openings of surrounding buildings that are within 6 feet;

k. less than 3 feet from an inside corner of an L-

shaped structure;

I. so that the bottom of the vent termination opening is

less than 1 foot above any surface that may support ice, snow, or debris;

m. so that the flue gases are directed toward

brickwork, siding or other construction, in such a manner that may cause damage from heat or

condensation from flue gases.

Even though the flexible venting is insulated, it cannot be run through an unheated space.

To do so could cause residual condensation inside the stainless steel liner, which may

eventually perforate the liner and allow vent gasses to enter the dwelling.

Installation considerations - DV-2000TM:

Select a location for the vent terminal in accordance with all local and national codes. The following

requirements shall be considered to be minimum requirements that can be overridden by stricter local

and national codes.

The vent shall not terminate: a. directly above a paved sidewalk or paved driveway

that is located between two buildings, and that serves both buildings;

b. less than 7 feet above any paved driveway;

CAUTION

Most codes have a notwithstanding clause

that states that products of combustion shall

not enter the dwelling under any

circumstances, even if all other code

requirements as to construction and location have been complied with. The installer is ultimately responsible to do whatever is

necessary to ensure that flue gasses do not

enter the dwelling.

Installation of side-wall venting - DV-2000TM:

Cuts and abrasion hazard.

Always wear protective gloves and eye

protection when handling the vent material

The process of cutting and fitting the flexible venting material exposes the installer to sharp edges that could cause severe cuts to the

skin.

Connection to the furnace breech - DV-2000TM:

1. Remove the standard breech plate by removing the brass nuts.

Determine which direction the venting will be routed

from the furnace and then install the special side- wall venting breech plate provided in the VTK

Series vent kit so that the breech plate test port will be accessible after vent installation. However, do

not install the breech plate with the test port pointing downward. Tighten the brass nuts.

The flexible venting has 4 pieces of corrugated spin sleeving that has been temporarily screwed on over

top of it. Remove the spin sleeving completely by unscrewing it in a counter-clockwise direction.

Using tin snips, cut the aluminium outer sleeve back by 5" for 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 ).

Prepare the furnace breech end of the insulated flex vent by first screwing the spin sleeve onto the

corrugated aluminium jacket (see figure #1.2) until the trailing edge of the spin sleeve is about 12" from

the end of the vent (see figure #1.3).

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

10.

Break the residual length of seal strip in to 3 equal parts and stuff them onto the screw heads of the

stainless steel self-drilling screws so that the screw heads are completely covered.

11.

Two stainless steel band clamps are provided in the VTK Series kits. Position one stainless steel band

clamp over the gum seal joint so that the edge of the clamp closest to the breech lines up with the

edge of the gum seal that is closest to the breech. Ensure that the band will close with an action of one

strip sliding over the other - not under the gearhead of the draw clamp (see figure #1.8). Tighten the

band clamp with considerable torque to cause the gum seal be squeezed into all crevices and to ooze

out of the end of the clamp closest to the breech (see figure #1.9). The gum will eventually become

rubbery.

12. The seal is permanent and should never need to be disconnected as the breech plate can be removed

for cleaning and inspection using the 4-bolt joint.

13. Tuck the vent insulation into the breech collar.

14.

Screw the spin sleeve tightly into the breech collar for a finished appearance. Wrap the other end of

the spin sleeve with aluminium tape to cover any metal burrs that may be present (see figure #1.10).

Cut the corrugated stainless steel core back by 3"

for the IFV Series vent. You should now have about

3" of insulation hanging out past the stainless steel core (see figure #1.4).

Push the stainless steel core onto the breech pipe as far as it will go (see figure #1.5) and

mechanically attach the vent to the breech 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).

With the stainless steel core now firmly attached to the breech, tear off one green gum-sealing strip

from the backing strip. Wrap the seal strip around

the joint, always keeping the centerline of the seal strip over the line where the corrugated stainless

steel core makes the transition to the smooth outer surface of the breech pipe. In other words, the seal

strip must be centered over the joint. After wrapping

Prepare the terminal end of the insulated flex vent by first screwing the spin sleeve onto the

corrugated aluminium jacket until the trailing edge of the spin sleeve is about 10" from the end of the

vent.

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

Cut the corrugated stainless steel core back by 3" for the IFV Series vent. You should now have

about 3" of insulation hanging out past the stainless steel core.

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

With the stainless steel core now firmly attached to the terminal, tear off the other green gum-sealing

strip from the backing strip. Wrap the seal strip around the joint, always keeping the centerline of

the seal strip over the line where the corrugated stainless steel core makes the transition to the

smooth outer surface of the terminal pipe. After

wrapping the seal strip around once, allow 1/2"

overlap and tear off the residual length.

Break the residual length of seal strip in to 3 equal parts and stuff them onto the screw heads of the

stainless steel self-drilling screws so that the screw heads are completely covered.

Position the other stainless steel band clamp over the gum seal joint so that the edge of the clamp

closest to the terminal lines up with the edge of the gum seal that is closest to the terminal. Tighten the

band clamp with considerable torque to cause the gum seal be squeezed into all crevices and to ooze

out of the end of the clamp closest to the terminal (see figure #1.11 ).

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 aluminium 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 - DV-2000TM:

1. Cut a 6" hole in the side-wall in accordance with the

location considerations outlined in the previous section.

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 TM 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" hole in the wall. This will accommodate the proper

Remove the 2 screws fastening the stabiliser shroud in place and remove the stabiliser shroud.

Insert the main body of the terminal through the wall plate so that the end of the terminal extends about

2" past the outside wall.

Install the stabiliser shroud and replace the two mounting screws. (see figure #1.13).

For concrete and block wall installations in particular, If it appears that the flange on the back

of the stabiliser 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.

Silicone seal the circumference of the joint where the stabiliser shroud connects to the main body of

the terminal.

Apply caulking to the back plate of the stabiliser shroud and push the terminal back firmly against

the wall.

10.

While pushing down gently on the top of the stabiliser shroud, install the 3 stainless steel 2"

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 position.

12.

Apply more caulking all around the seam where the stabiliser 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.

description.

5) AIR FOR COMBUSTION

Poison carbon monoxide gas hazard.

Comply with NFPA standard for the installation of Oil Burning Equipment and

applicable provision of local building codes to provide combustion and

ventilation air.

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

The following areas or types of structures may contain or have exposure to the substances listed below. The

installation must be evaluated carefully as it may be necessary to provide outside air for combustion.

a. Commercial building. b. Building with indoor pools.

c. Furnaces installed near chemical storage areas.

Exposure to these substances:

a. Permanent wave solutions 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 solvent (such as perchloroethylene).

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

j. Hydrochloric acid.

k. Solvent cements and glues. I. Antistatic fabric softeners for clothes dryers.

m. Masonery acid washing materials.

5.3) Ducted outdoor combustion air:

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,

doors, and weather stripping have dramatically reduced the volume of air leakage into the home.

Home air exhausters are common. Bath and kitchen fans, power vented clothes dryers, and water heaters all

tend to create a 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. The HRVs are not designed to supply

combustion air. tf not properly balanced, a serious negative pressure condition could develop in the

dwelling.

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 for combustion.

Three burners are set up to duct outside combustion air directly to the burner; the Beckett AFII and Riello 40-BF

for side-wall venting using the new DV-2000 TM venting system, and the Beckett AFG for use with conventional chimney venting. The Riello 40-F is not suitable for

direct-connected outdoor air.

CAUTION

The use of ducted outside combustion air is

mandatory for the DV-2000 TM venting system.

This system operates on a balanced flue

principle and will not function properly if the combustion air piping is not attached and sealed at all connections between the vent terminal and burner inlet.

Outdoor combustion air kit - chimney venting:

The following kit has been certified for use on 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 blocked

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 air from the outdoors again:
