1.2.1 Safety Rules
Your unit is built to provide many years of safe and
dependable service provided it is properly installed and
maintained. However, abuse and/or improper use can shorten
the life of the unit and create haza rds fo r you , the ow ner.
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 others. Carbon monoxide
can cause death and/or serious bodily injury. Therefore,
to help alert people of potentially dangerous carbon
monoxide levels, you should have carbon monoxide
detectors listed by a nationally recognised agency
(Underwriters Laboratories or International Approval
Services) installed 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. Ther efore,
in order to alert people to 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 bel ow ).
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
An air pressure switch MUST be used when the furnace
is side-wall vented.
CAUTION
Do not use any commercially available soot remover.
This furnace has a ceramic fibre type of combustion
chamber. Normal servicing of this unit does not require
the cleaning of same. Use extreme caution if for any
reason you have to work in the area of the combustion
chamber.
1.2.2 Freezing Temperature and Your Structure
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 ke ep it from
operating if sensors detect abnormal conditions such as
exhaust flues obstructed by snow, ice o r de bris.
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:
CSA B139Installation Code for Oil Burning
Equipment
NFPA 31 Installation of Oil Burning Equipment
ANSI/NFPA 90B Warm Air Heating and Air Conditioning

1.4 VENTING
1.4.1 General
Furnaces can be vented in seve ra l way s:
Chimney Vented
Using the Beckett AFG or Riello 40-F burner, the furnaces can
be chimney vented with or without a b arometric damper. Th e
unit will operate at a negative overfire draft and flue draft.
WARNING
Poisonous carbon monoxide gas, fire and
explosion hazard.
Read and follow all instructions in this section.
Failure to properly vent this furnace can cause
death, bodily injury and/or property damage.
WARNING
Poisonous carbon monoxide gas hazard.
Never vent this furnace together with another
combustion appliance when side-wall venting.
To do so may result in asphyxiation and death to
the occupants.
Side-wall Vented
Using the Beckett AFII or Riello 40-BF burner with the integral
pre- and post-purge controls, the system can be side-wall
vented for maximum efficiency and wit hout the use of a side-

1.4.2 Chimney installations
When set up for chimney venting, this furnace is certified for
use with an L-vent, A-vent, tile-lin ed and metal-liner-tile lined
chimney, and can be vented both with and without a
barometric draft damper. However, this furnace is not
approved for use without a barometric damper if it is to be
vented together with another oil-fired appliance such as a
water heater.
With a barometric damper
This furnace may be vented into a chimney of suitable size
and adequate chimney base temperature, as specified in the
Installation Code. When a bar ometric damper is used, the air
entering the damper reduces the possibility of vent
condensation. The relevant excerpt from the code is found in
this section and can be used as a guide where local or
national codes do not exist. One option to increase the
chimney base temperature is to use vent connection
insulation.
WARNING
Poisonous 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 the
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 death, personal injury
and/or property damage.
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 gases is
raised. To offset the increased tendency for vent
condensation, the chimney must be lined. The liner must be
insulated according to t he insulati ng procedur e recommended
by the manufacturer of the liner. Also, the vent connector
should be as short as possible and be either of double wall
construction or of single wall constr uction with 2.54 cm (1”) of
insulation.
wall power vent. The unit will operate at a positive overfire
draft and flue draft.

CAUTION
When the furnace (chimney installation) is vented
together with other combustion appliances such as a
water heater, the allowable venting materials for use
with those appliances must be investigated (“L”-vent,
etc.).
Flue pipe sizing
The following table is an excerpt from the Installation Code
and indicates the permitted flue sizes and minimum base
temperatures for circular flues in chimneys with a thermal
resistance of less than R6 (6 ft
appliance, burner, or chimney is installed, chimney vent sizes
and maximum flue gas temperat ures shall comply with Table
2 (measured at the chimney connector with the barometric
damper shut, after 5 minutes o f operation).
Note: Thermal resistance values for typical chimneys are as
follows:
R6 (6 ft2 •hr •°F / Btu): Metal or clay-lined masonry
Applying Ta ble 2
If a furnace with a 0.60 USGPH nozzle is to be connected to a
6.1 m (20') tall clay-lined masonry chimney, the thermal
resistance of this type of chimney is R2, (which is less than
R6). The actual firing rate at 156 psig is 1.25 x .60 = .75
USGPH. Therefore this table shall apply as follows:
The minimum size permitted shall be 10.16 cm (4") in. insid e
diameter;
The maximum size permitted shall be 12.70 cm (5") inside
diameter;
The minimum base temperature shall be about 160°C
(320°F).
1.4.3 Side-wall venting - DV-2000™

glass fibreboard.)
The notable characteristics of the DV-2000™ system are as
follows:
a) 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;
b) One hole of minimal size 15.24 cm (6") 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 safet y 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 and vent circuits within the terminal can be
accessed for cleaning.
There are 3 main components to the DV-2000™ system; the
vent terminal kit VTK-1 (for models OLF/R105, OUF105,
NOUF105 and NOLF105) or VTK-2 (for models OLR160,
OUF160) and the insulated flexible venting material IFV3 (for
models OLF/R105, OUF105, NOUF105, NOLF105) or IFV4
(for models OLR160, OUF160) and the f ield-supplied 3” PVC
or ABS intake piping.
WARNING
Poisonous carbon monoxide gas hazard.
Even though the flexible venting is insulated, it
must not be run through an unheated space.
To do so can cause residual condensation inside
the stainless steel liner. This may eventually
perforate the liner and allow vent gasses to enter
the dwelling, which can result in death, personal
injury and/or property damage.
Insulated flexible venting - DV-2000™
The certified venting materia ls come in 3 lengths, Model No.
IFV3-15, IFV3-23 and IFV3-30 or IFV4-1 5, IFV4-23 and IFV430 for 160 models correspond to 15, 23 and 30' 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 aluminium sleeve to protect
the insulation. Splicing vent lengths together is prohibited.
The maximum and minimum continuous vent lengths
permitted for installation are:
1.5 m (5') minimum 9 m (30') maximum
must be directly connected to the burner or the DV2000™ venting system will not function.

7. Pull the insulation back to expose the corrugated
stainless steel core.
8. Cut the c orrugated stainless steel core back by 7.6
cm (3") on the IFV Series vent. You should now have
about 7.6 cm (3") of insulation hanging out past the
stainless steel core (see Figure 1.4);
9. Push the stainless steel core onto the breech p ipe as
far as it will go (see Figure 1.5) and mechanically
attach the vent to th e 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 in the centre at the top. Start the
drill point of the screws in the valleys of the
corrugations 9-16 mm (3/8"-5/8") back from the end
of the stainless steel core, so the screw heads can
be properly sealed in the following operations (see
Figure 1.6);
10. With the stainless steel core now firmly attached to
the breech, tear off one green gum-sea ling strip f rom
the backing. Wrap the seal strip around the joint,
always keeping t he centreline of the seal strip over
the line where the corrugated stainless steel core
makes the transition to th e smooth outer surface of
the breech pipe. In other words, the seal strip must
be centred over the joint. After wrapping the seal
strip around once, allow a 12 mm (1/2") overlap and
tear off the residual length (see Figure 1.7);
11. Break the residual length of seal strip in to 3 equal
parts and stick them onto the heads of the stainless
steel self-drilling screws so t hat they are completely
covered;
12. 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 lin es up with the edg e 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 gear head of the
draw clamp (see Figure 1.8). Tighten the band clamp
with considerable torqu e t o c au se t h e gum s e a l t o 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;
13. 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;
14. Tuck the vent insulation into the breech collar;
15. 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);
Connection to the vent terminal - DV-2000™
1. 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 0.25 m (10") from the end of the
vent;
2. Us ing s harp ti n snips, c ut the al umi nium oute r sleeve
back by 0.13 m (5") 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 76 mm (3") on
the IFV Series vent. You should now have about 76 mm (3")
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 in the centre at the top. Start
the drill point of the scre ws in th e valleys of the corrugations 916 mm (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, tear off the other green gum-sealing strip from the
backing. Wrap the seal strip around the joint, always keeping
the centreline 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 a 12 mm (1/2") overlap and tear
off the residual length;
7. Break the residual length of seal strip in to 3 equal parts and
stick them onto the heads of the stainless steel self-drilling
screws so that they are comp lete ly co ve red ;
8. Position the other stainless steel band clamp over the gum
seal joint so that the edge of the clamp cl osest to the terminal
lines up with the edge of the gum se al that is closest to the
terminal. Tighten the band clam p with considerable torque to
cause the gum seal be s queez ed int o all cr evic es and t o ooz e
out of the end of the clamp closest to the te rminal (see Fig ure
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
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-2000™
1. Cut a 0.15 m (6") hole in the side-wall i n accordance with the
location considerations outlined in the previous section;
2. Fasten the wall plate to the inside-wall using 4 field-pr ovided
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 ac cess the top right wall
plate screw hole. For concrete and block, Tapcon™ screws or
equivalent are recommend ed. Install the wall plate so that th e
top of the hole in the wall plat e is posit i o ned 3 mm ( 1/8 ") l ower
than the top of the 0.15 m (6") hole in the wall. This will
accommodate the proper slope of the terminal, in the direction
from the inside to the outside;
3. Remove the 2 screws fastening the end cone in place and
remove the cone
4. Remove the 2 screws fastening the stabiliser shroud in place
and remove the stabiliser shroud;
5. Insert the main body of the terminal through the wall
plate so that the end of the terminal extends about
50 mm (2") past the outside wall;
6. Install the stabiliser shroud and replace the two
mounting screws. (see Figure 1.13);
7. On concrete and block wall installati ons 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;
8. Silicone seal the circumfere nce of t he j oint where the
stabiliser shroud connects to the main body of the
terminal;
9. Apply caulking to the back plate of the stabiliser
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"
screws provided with the kit to secure the back of the
shroud to the wall. Do not over t ighten 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 posi tioning;
11. Tighten the clamp on the wall plate to secure the
terminal in place;
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 surfac es
such as lapped siding;
13. Install the end cone and replace the two mounting
screws;
14. Support the vent and intake air piping so tha t a 6 to
13 mm (1/4 to 1/2") s lope (toward the outside) r e s u lts
for proper drainage out the terminal body.

Air – Side-wall Venting, DV-2000™ for a complete
description.
1.5 AIR FOR COMBUSTION
WARNING
Poisonous carbon monoxide gas hazard.
Comply with NFPA or CSA 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 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 requirements for the
furnace. However, home improvements such as new windows,
doors, and weather stripping hav e drastically reduced the volume
of air infiltratio n i n to the home .
Home air exhausters are common. Bathroom 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 Systems (HRVS) 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
Installations 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 be
exposed to certain substa nces, potentially requiri ng outside air for
combustion:
a. Commercial buildings;
b. Buildings with indoor pools;
c. Furnaces installed near chemical storage areas.
Exposure to the following substances:
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 solvent (such as perchloroe thy lene);
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 materi als.
1.5.3 Ducted outdoor combustion air
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 and the
Beckett AFG for use with conventional chimne y 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™ 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.
12
Outdoor combustion air kit – chimney venting
The following kit has been certified for use on this
appliance. The kit contains 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 cl ose and the burner will dra w all
air from the outdoors again.
CAS-2B Components (except air duct) for the Beckett
AFG burner: The kit includes the intake terminal, vacuum
relief valve (VRV) and special air boot connection with
integral air adjustment means for the AFG burner. The
CAS-2B can be used with a 0.10 m (4") galvani zed steel
air duct or with a 0.10 m (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 on the outside of the intake
pipe.
CAD-1 This air duct kit consists of 7.6 m (25') of
insulated UL/ULC Listed Class 1 air duct and two 0.10 m
(4") steel band clamps. The duct incorporates a
corrugated flexible aluminium core, surrounded by
fibreglass insulation and a viny l vapour barrier.
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 kit.
Outdoor combustion air – side-wall venting, DV2000™
The DV-2000™ venting system is a sealed system and
completely isolates the furnace from the interior of the
building. The burner is total ly unaffected by any pr essure
fluctuations within the building which makes it ideal for
tight home construction.
The DV-2000 ™ venting system req uires ad ditio nal parts,
which are not included with the kit. These additional parts
must be constructed of 3" Schedule 40 PVC, PVC-SWV,
SDR-26,SDR-21, Septic Sewe r Pipe, or ABS plast ic pip e,
fittings and sealant. Also, installation procedures, piping
and fittings must conform to the following ANSI /ASTM
standards:
PVC ASTM D-1785
SDR26, SDR21 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" elbow fitting as required;
b. 3" plastic pipe;
c. 3" - 90° elbow, female-female(for terminal);
d. 3" female to 2” redu ce r (Riello 40-BF burner only);
e. 2".-.9 0° elbow, street type, female-male (Riello 40-BF burn er
only);
f. 3" female-female PVC or ABS coupling (not sewer pipe)
(Beckett AFII burner only);
g. Transition bushings to go fr om PVC or ABS to ASTM D2729
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 - DV-2000™
The DV-2000 ™ venting system has been certified for 36
equivalent meters (120') of 3" intake pipe. Count a 90° elbow as
3.0 equivalent meters (10') and a 45° elbow as 1.5 equivalent
meters (5') in the calculation.
For Example:
2 lengths of 1.5 m (5') = 3.0 equivalent meters (10')
1 length of 3.0 m (10') = 3.0 equivalent meters (10')
3 elbows 90° = 9.0 equivalent me ters (30 ')
2 elbows 45° = 3.0 equivalent me ters (10 ')
1 elbow 90° = 3.0 equivalent me te rs (10')
1 elbow 45° (Riello Burner) = 1.5 equivalent meters ( 5')
Total=23.0 equivalent meters (75'),
Intake pipe installation - DV-2000™
Obtain the necessary additional parts, to complete the installation,
and start the piping at the burner. If the optional vestibule has been
installed, remove the appropriat e knockouts in the side panels of
the vestibule. The lower 5" knockout in the right hand panel is used
for the Beckett AFII burner. T he higher 5" knockouts on the right
and left-hand panels are for right or left connection to the Riello 40BF burner.
Beckett AFII burner
Remove the burner intake cover by removing the 3 screws
securing it in place. Discard the cover and screws. Liberally apply
silicone around the end of a 3" coupling and fully insert the
siliconed end into the burner opening. Fasten securely with 3 selftapping sheet metal screws.
Riello 40-BF burner
Fully insert the female end of the 2" - 90° street elbow into the
combustion air fitting on top of the burn er. Fasten securely with 3
self-tapping sheet metal screws. Cement the 2" end of the 3"
female to the 2” female reducer onto the male end of the 2" - 90°
street elbow. If these parts are not easily obtained, use a 3" - 90°
street elbow with the male end fitted over the combust ion air fitting.
The fitting will have to be silicone sealed as the fit is a bit loose.
Fasten securely with 3 self- tapping she et me tal screws.
Terminal connection
Insert the 3" - 90° female-female elbow onto the st ainless steel air
intake fitting located o n the right side of the vent term inal (viewed
from the rear). Fasten securely with 3 self-tapping sheet metal
screws.
which is acceptable.
13
Intermediate piping
Piping between the terminal and the burner. Ensure that
the 3" piping is routed and supported in accordance with
local and national codes. Obey minimum furnace
clearances to combustibles when routing any section of
3" piping in the vicinity of the furnace. If Septic Sewer
Pipe is to be used, install transition bushings at the 3"
female ends of the fittings at the burner and at the
terminal. Transition bushings are readily available and are
required because 3" PVC and ABS pipes have a typical
outside diameter of 3.5", wher eas Septic Sewer Pi pe has
a typical outside diameter of 3.25".
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 having the fuel oil tank below burner level
must employ a two pipe fuel supply system with an
appropriate fuel pump; for more th an a 2.4 m (8') r ise us e
a 2-stage pump; for more than 4.9 m (16') rise an
auxiliary pump.
Follow the pump instructions to determine the size of
tubing you need in relation of the lift, or the horizontal
distance.
Prior to each heating season, have the entire oil
distribution system checked for leaks.
1.7 BURNER INSTALLATION
Mounting the burner
1. Check the insertion depth of the burner tube. Refer
to the Technical Specifications p. 23 to 25.
2. The burner mounting plate on the furnace has a 4-
bolt configuration;
3. Position the mounting g asket between the mounting
flange and the appliance burner mounting plate. Line
up the holes in the mounting flange with the studs on
the mounting plate and securely bolt in place.
After the burner is mounted
a. Remove drawer assembly or air tube combination;
b. Install nozzle (see specifications);
c. Confirm electrode settings;
d. Make the electrical connections;
e. Complete oil line connections.
CAUTION
Do not turn on the burner until you have checked
the following:
Checking the polarity
The oil burner used on the furnace has a solid state
control system which is sensitive to the proper connection
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.
FIGURE 2
Checking the nozzle
DNS-0864 Rev. A
The burner is equipped with the appropriate nozzle. However, if
another size nozzle or replacement nozzle is required, use the
manufacturer’s nozzle data concerning spray angle, type as
shown in Tables 4.1 to 4.3. Note that all nozzle sizes are based
on a pump pressure of 100 psig.
Always select nozzle sizes by working back from the actual
desired flow rate at operating pressure, and not by 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 Tables 4.1 to 4.3. Once the
burner becomes operational, final adjustments 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 the fuel tank is f illed with clean
oil.
IMPORTANT
When using nozzle sizes of less than .75 USGPH, the
Installation Code for oil burning equipment requires the
installation of a 10 (or less) micron filter in the fuel oil line.
ICP requires that this practice be followed in order for the
lifetime heat exchanger warranty to be kept intact.
14
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 death, personal injur y
and/or property damage.
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 DEVICE
(BVSO) For chimney venting
WARNING
It is imperative that this device be installed by
a qualified technician.
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. The device will then need to be
restarted MANUALLY.
Refer to the wiring diagrams and the detailed
instructions supplied with the BVSO for the installation
and wiring procedures. The length of wires supplied with
the unit is such that the safety device must be installed
between the flue outlet of the appliance and the draft
regulator, as indicated in the instructions.
It is further imperative that the BVSO be maintained
annually. Refer to the instructions supplied with the
device itself, as well as Section 3. of this Manual.
CAUTION
Do NOT use the BVSO on a positive pressure
venting system (Sealed Combustion System or
Direct Vent). 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 death, bodily
injury and/or property damage.
1.9.1 Electronic air cleaner
Wire terminals are provided to direct 115 volts @ 0.5 Amp
maximum to an Electronic Air Cleaner (EAC). Power will be
available to the EAC at all times, so it must incorporate a flow
proving switch if it is to be wire d into the furnac e control box. Most
modern EACs have the required integral airflow proving switch.
Wire the electronic air cleaner between terminals #5 and #2. Refer
to wiring diagram, Figure 6.
1.9.2 Humidifier
The red wire from burner can be used to direct 115 volts @ 1.0
Amp maximum to the transformer
powering the humidifier. The
humidifier will be energised anytime the burner is operating in the
“Heating Mode”. Refer to wiring diagram, Figure 6.
1.9.3 Air conditioning
An air conditioning coil may be installed on the supply air side only.
Also, notwithstanding the evaporator coil manufacturer’s
instructions, a minimum of 15 cm (6") c learance must be allowed
between the bottom of the coi l drain pan and the top of the heat
exchanger. Wire the thermostat and condensing unit contactor as
indicated in Figure 6 .
1.9.4 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 and/or national codes and good
trade practices.
When furnace supply ducts carry air outside furnace area, seal
return air duct to furnace casing and terminate du ct outsid e furnace
space.
Install air conditioning cooling coil (evaporator) on downstream
side 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 ai r fro m the ev apor at or c o il go i ng
through the furnace could cause condensation an d shor ten fu rna ce
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 duct can result in death,
personal injury and/or property damage.
15
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.

If the terminal vent or intake openings become blocked to the
point where the set point of the pressure switch is exceeded
during a firing cycle, the flame will shut down and the burner
will go into the indefinite recycling post-purge mode as
described above, until the blockage is removed.
2.3 CHECKS AND ADJUSTMENTS
2.3.1 General
During initial start-up and subsequent yearly maintenance
calls, the furnace must be thoroughly tested .
Open the oil bleed port screw and start the burner. Allow the
oil to drain into a container for at least 10 seconds. The oil
should flow 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. Then slowly close and tighten the bleed
screw. Fire the burner. Adjust the o il pressure as indicated i n
Tables 4.1 to 4.3.
IMPORTANT
The burner must be put in operation for at least 10
minutes before any test readings are taken. For new
installations, set up the burner to the settings in Tables
4.1 to 4.3 before firing. These are rough adjustments
but they will ensure that the burner will start and run
smoke-free in advance of the final adjustments to be
made.
2.3.2 Restart after burner failure
1. Set thermost at lower than the room te mp er ature;
2. Press the reset button on the burner primary control (relay);
3. With side-wall v enting and Riello burner, set thermostat higher
than the room temperature for 10 seconds, then set lower than
room temperature. This will start pre-purge cycle. Repeat twice;
4. Set thermost at h i g h er t ha n th e ro om te mp er at ure;
5. If the burner motor does not start or ignition fails, turn off the
disconnect switch and CALL A QUALIFIED SERVICE
TECHNICIAN.
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. Always keep
the supply valve closed if the burner is shut down for an
extended period of time.
17
2.3.3 Combustion chamber curing
Some moisture and binders remain in the ceramic combustion
chambers after fabrication. It is important to clear the chamber
of this residue before testing. If you smoke test before cur ing,
the instrument may become dam aged. To cure the chamber,
run the unit for 3 consecutive cycles, with 3 minutes of
elapsed time in between each cycle. The burner must operate
for about 3 minutes per cycle. The exhaust will have a
pungent odour and produce a white cloud of steam.
2.3.4 Smoke / CO2 test
1. On chimney installati ons, pierce a test hole in the smoke
pipe 18’’ above the furn ace breech. On side-wall vented
installations, remove the threaded cap from the extended
test pipe that is welded int o the 4-bolt breech plate. I nsert
the smoke test instrument probe into the open hole;
2. From a cold start, let the unit operate during 5 to 10
minutes;
3. Set the burner air setting until just a trace of smoke
results (#1 on the Bacharach scale);
4. Take a CO
sample at the same test location where the
2
#1 smoke reading was taken and make note of it.
Example: 13.8% of CO2 or 2.5% of O2;
5. Adjust the burner air setting to obtain a CO2 reading
1.5% lower (or a O2 reading 2.0% higher) than the
reading associated with the #1 sm oke. Example: 12.3%
or CO2 or 4.5% of O2;
6. This method of adjusting the burner will result in clean
combustion and ensure the proper functioning of the
system.
2.3.5 Perform the supply air temperature rise test
1. Operate the burner for at least 10 minutes;
2. Measure the temperature of the air in the return air
plenum;
3. Measure the temperature of the air in the largest trunk
coming off the supply air plenum, just outside the range of
radiant heat coming off the heat exchanger; 30 cm (12")
away from the plenum on the main take-off is 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 4.1 to 4.3, change to the next higher blower
speed tap until the temperature rise falls to this
temperature or below. If the excessive temperature ris e
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.
2.3.6 Vent temperature test
1. After 5 to 10 minutes of operation, pla ce a th ermometer in
the test hole located in the breech pipe;
2. The vent temperature should be between 204 and
302°C (400 and 575°F). If not, check for improper air
temperature rise, pump pressure, nozzle size, or for a
badly sooted heat exchanger.
2.3.7 Overfire pressure test procedure
The overfire draft that is taken through the observation port,
located above the burner, is a measurement necessary to
determine if there is a blockage in the heat exchanger or the
flue pipe. Refer to the Technical Specifications in this
manual for overfire pressure values. A high pressure
condition may be caused by excessive combustion air, du e
to the air band being too wide open, or a lack of flue draft
(chimney effect) or some other blockage, such as soot in the
secondary section of the heat exchanger or the use of an
oversize nozzle input or high pressure pump.
2.3.8 Fan-Limit adjustment
Modification of the “FAN ON” and “HI” limit settings on the
Fan-Limit can cause a malfunctioning of the furnace and result
in premature wear of the heat exchanger.
Please refer to the different adjustment values in Figure 4.
CAUTION
Modification of the factory set limits will void the
warranty.
2.3.9 Limit control check
After operating the furnace for at least 15 minutes, restri ct the
return air supply by blocking the filters or the return air register
and allow the furnace to shut off on High Limit. The burner will
shut off but the blower will continue to run.
Remove the obstruction and the burner shoul d restart after a
few minutes.

incorporates a safety shutdown system that will shut the
burner down before #1 smoke occurs due to the presence of a
blocked intake or blocked vent outlet. Test the system as
follows:
1. Ensure that the furnace has been running for at least 10
minutes;
2. Gradually block the intake. The burner flame should shut
down before a #1 smoke reading occurs;
3. Gradually block the vent outlet. The burner flame should
shut down before a #1 smoke reading occurs;
4. If the burner does not shut down before a #1 smoke
occurs, ensure that the burner is set up according to Pa rt
2, section 3.4 (2.3.4). Perform the CO
allow for the 1.5% CO
operating play required by the
2
/ Smoke Test, and
2
instructions;
5. If the burner still does not shut down before a #1 smoke
occurs, check for a blockage of the pressure hose, or at
the hose connection points.
IMPORTANT
The DV-2000™ safety shutdown system will shut down
the burner flame during a blocked intake or blocked
vent condition if and only if, the burner has been set up
and calibrated in accordance with Tables 4.1, 4.2 or 4.3.
Perform the CO2/ Smoke Test. For instance, if the
burner is adjusted and final-set to a #1 smoke condition
during normal operation, the burner flame cannot
possibly shut down before #1 smoke occurs during a
blockage condition.
2.3.11 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.

PART 3
MAINTENANCE
3.1) GENERAL
Preventive Maintenance
"Preventive maintenance" is the best way to avoid
unnecessary expense and inconvenience. Have your
heating system and burner inspected at regular intervals
by a qualified service technician.
WARNING
Electrical shock hazard.
Turn OFF power to furnace before any disassembly
or servicing.
Failure to do so can result in bodily injury and/or
death, property damage.
A complete combustion test must be performed after each
annual service inspection of the unit, to maintain optimum
performance and reliability.
Do not tamper with the unit or controls. Call a qualified
service technician.
Before calling for service, check the following
a. Check oil tank gauge and check if the valve is open;
b. Check fuse or circuit breaker;
c. Check if shut-off switch is “ON”;
d. Set thermostat above room temperature;
e. If ignition does not occur, turn off the disconnect switch
and call a qualified service technician.
When ordering replacement parts, specify the complete
furnace model and serial number.
3.1.1) Heat exchanger
The entire heat exchanger should be inspected annually for
soot accumulation. If the burner is operating normally there
should be very little soot accumulation. If the heat exchanger
requires scale removal, use a wire brush first, to loosen the
scale and then vacuum the soot and scale that has fallen into
the secondary heat exchanger (radiator) section. You will find
that a 36" long flexible hose at tachment will be helpful to reach
into the back of the radiator. A piece of 1/2" flexible gas
connector, or a piece of 1/2" liquid-tight vinyl jacket metallic
electrical conduit works well as a makeshift device .
Cleaning the heat exchanger
Remove the 4-bolt flange from the front of the furnace to
expose the clean-out port and check for soot deposits. If there
is very little soot in the radiat or section visible fr om the cleanout port, you will not need to clean it. However, if you notice
scaling in the radiator, you should remove it.
The wrap-around radiator can now be cleaned entirely from
the front inspection port. The furnac e also has external c leanout ports so the soot does not fall into the fan compartment
during the cleaning operation.
IMPORTANT
Do not vacuum the ceramic chambers—they are easily
damaged.
Soot will have collected in the first sections of the heat
exchangers only if the burner was started after the combustion
chamber was flooded with fuel oil, or if the burner has been
operating in a severely contaminated condition.
3.1.2) Refractory firepot
Remove the burner and check the firepot.
IMPORTANT
This furnace has a fibre type refractory combustion
chamber. Normal servicing of this unit does not require
cleaning of the combustion chamber.
If cleaning of the pot should be required, use extreme
care. After firing, the pot becomes very fragile. Do not
use any commercially available soot removers.
If the pot is damaged, it must be replaced. A damaged pot
could lead to premature heat exchanger failure. Cracking of
the firepot is normal, however, replace the pot only if the
cracks have propagated more than 2/3 the way through the
wall thickness. The average wall t hickness of the f irepot is 1 9
mm (3/4").
Flooding of the firepot
Flooding can occur when the oil primary control has been
reset a number of times in a no-heat s ituati on. Eac h time oil i s
fired into the pot and does not ignite, it is absorbed into the
pot. Even if the burner is removed and the pot is felt for
wetness, it is difficult to assess the degree of oil absorption by
the pot.
There is only one way to properly service a flooded firepot,
and that is to replace it.
CAUTION
If you observe the red warning light on the burner, push
ONLY once to try and restart. If the burner does not
start, call a qualified service technician. Do NOT press
the button again.
Self-aligning firepot
The primary heat exchanger of the furnace is comprised of an
upper and lower half. The lower half is essentially a “can” that
contains a self-aligning fire pot. The firepot fits into the bottom
half in one direction only.
20
Removing the firepot
The firepot is seldom replaced, but when it must be replaced
one must simply:
1. Remove the burner;
2. Remove the burner Limit Control;
3. Remove the breech plate;
4. Remove the front panel;
5. Remove the brass nuts on the stainless steel heat
exchanger studs;
6. Pry the bottom half of the heat exchanger apart by using
the designated prying tabs;
7. Remove the bottom half of the heat exchanger through
the front of the furnace;
8. Pull the firepot up and out of the bottom half of the heat
exchanger;
9. Remove the old sealing gasket from the flange of the
upper half of the heat ex changer;
10. Scrape any residual gasket material off the matching
flanges of the heat exchanger.
Replacing the firepot
1. Align the slot at the front part o f the firepot with the burner
tube sleeve and gently lower the firepot into the bottom
half of the heat exchange r;
2. Holding the firepot near the perimeter, gently push the
firepot all the way into the bottom half of the heat
exchanger until it is properly seated;
3. Thoroughly wet the gasket with water using a spray pump
bottle, position the tabs over the studs, and push the
gasket upward against the sealing flange of the upper half
of the heat exchanger;
4. Install the brass nuts on the studs by engaging only 2 or 3
threads;
5. Position the bottom half of the heat exchanger under the
upper half and align the bottom half so that the slots in the
bolting tabs engage the stainless steel studs. There is no
further need to hold onto the bottom half as it will now be
suspended on the stud nuts;
6. Push upward on the housing and thread the nuts fingertight as far as possible;
7. Intermittently tighten the brass nuts with a wrench in a
sequence that will pull the heat exchanger halves
together evenly. Tighten all nuts to 90 inch-lbs torque
once and then alternately re-tighten all nuts again to 100
inch-lb. THE RE-TIGHTENING SEQUENCE IS
ABSOLUTELY NECESSARY TO ENSURE A TIGHT
JOINT;
8. Re-assemble the front panel, breech plate, Limit Control
and burner in reverse sequence to their removal;
9. Follow the instructions for starting the burner for the first
time to cure the firepot and perform combustion checks.
3.1.3) Drawer assembly
Remove the drawer assembl y. Clean all foreign matter from
the retention head and electrodes. If a Beckett AFG burner
has been installed, the burner will have to be removed to
check the retention head.
3.1.4) Nozzle
Replace the nozzle with the one specified in Tables 4.1 to 4.3.
3.1.5) Oil filter
Tank filter
The tank filter should be replaced as requi red.
Secondary filter
The 10 micron (or less) filter cartridges should be replaced
annually.
3.1.6) Air filters
Air filters are the disposab le type. They shou ld be replaced at
least once a year. Dusty conditions, presence of animal hair
etc. may require more frequent filter changes. Dirty filters will
impact furnace efficiency and increase oil consumption.
3.1.7) Motor lubrication
Do NOT lubricate the oil burner motor or the direct drive
blower motor as it is permanently lubricated.
3.1.8) CAS-2B combustion air kit
If used, check the CAS-2B combustion air kit for proper
operation. Check to see that the inlet screen is not plugged.
Block the air inlet completely and ensure that a zero smoke
reading results. If a zero smoke reading is not obtained, set up
the burner as indicated in Tables 4.1, 4.2 or 4.3.
Gradually block off the intake. The CO2 should increase to a
maximum of 0.5 percentage points at the fully blocked
condition. If not, check that the VRV gate is pivoting freely and
that the pivot rod is in a horizontal position. Also, check that
the counterweight has been properly adjusted in accordance
with CAS-2B installation instructions.

3.1.9) BLOCKED VENT SHUT-OFF DEVICE (BVSO)
For continued safe operation, the Blocked Vent Shut-Off
System (BVSO) is required to be inspected and maintained
annually by a qualified technician.
1. Disconnect the power to the appliance;
2. Remove the two screws holding the BVSO assembly
3. Remove the cover;
