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 s horten 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 to pot entially dangerous carbon
monoxide levels, you should have carbon monoxide detectors
listed by a nationally recognised agency (ex. 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 buil ding or
dwelling. Fire or smoke can cause serious bodily injury, death,
and/or property damage. Therefore, in order to alert people to
potentially dangerous fire or smoke conditions, you should have
Underwriters Laboratories listed fire and smoke detectors
installed and maintained in the building or dwelling (see Note
below).
NOTE: The manufacturer of your furnace does not test
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 Temperatures 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 keep it from
operating if sensors detect abnormal conditions such as clogged
exhaust flues.
If the structure is unattended durin g cold weather you sh ould take the
following precautions:
a. Tu rn off main water suppl y into the structure a nd 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 enoug h 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 follo wed.
Some of the codes that may be applicable are:
CSA B139 INSTALLATION CODE FOR OIL
BURNING EQUIPMENT
NFPA 31 INSTALLATION OF OIL B URN ING
EQUIPMENT
ANSI/NFPA 90B WARM AIR HEATING AND AIR
CONDITIONING SYSTEMS
ANSI/NFPA 70 NATIONAL ELECTRICAL CODE
CSA C22.1 CANADIAN ELECTRICAL CO DE
Only the latest issues of the above codes should be used.
1.3) POSITIONING THE FURNACE

1.3.1) Location
Position the furnace as closely as possible to the chimney or vent
terminal, providing ample clearance to permit easy accessibility for
cleaning the inside of the furnace, the removal of filters, blower,
motors, controls and flue connections.
This furnace is approved for reduced clearances to combustibles.
Therefore, it may be installed in an alcove, closet, or crawl space.
Clearances indicated on the rating plate must be respected.
In the downflow position, this furnace is approved for installation on
combustible floors only when the accessory No C FB-1 "Combustible
Floor Base" is used.
In the horizontal position (air left or right), this furnace is approved for
installation on combustible floors only when the accessory No. HFB-1
"Horizontal Floor Base" is used.
In the horizontal position (air left or right), this furnace may be
suspended using an angle iron frame with threaded rod hangers.
Appropriate calculations, considering the weight of the furnace and the
frame must be made.
However, do not install furnac e dir ectly on carp et o r othe r c ombus tibl e
material, which can trap air under the floor.
The furnace must be installed level for safe and quiet operation.
CAUTION
Do NOT operate the furnace in a corrosive a tmosphere
containing chlorine, fluorine or any other damaging
chemicals. Refer to Part 1, section 5.2.
1.4) VENTING
1.4.1) 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
operate at a negative overfire draft and flue dra ft.
TABLE 1
RECOMMENDED ACCESS
FOR SERVICE
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
bodily injury or death, property damage.
Side-wall Vented
Using the Beckett AFII or Riello 40-BF burner with the integral preand post-purge controls, the system can be side-wall vented with the
new DV-2000™ venting system f or maximum efficiency and without
the use of a side-wall power vent. The unit will operate at a positive
overfire draft and flue draft.
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
1.4.2) Chimney installations
When set up for chimney venting, this furnace is certified for use with
an L-vent, A-vent, tile-lined and metal-lin er-tile lined chimn ey, 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 appli ance such as a water
heater.
With barometric damper
This furnace may be vented into a chimney of suitable size and
adequate chimney base temperatur e, as specified in the Installation
Code. When a barometric damper is used, the ba sement 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.
5
Without barometric damper
445 01 4024 05
Due to the lack of dilution air that would ordinarily be drawn into the
barometric damper, the dew point of the flue g ases is raise d. To offs et
the increased tendency for vent condensation , the chimney must be
lined. The liner must be insulated according to the insulating
procedure recommended by the manuf acturer of the liner. Also, the
vent connector should be as short as p ossible an d eithe r be of do uble
wall construction or of single wall construction with 25.4 mm (1") of
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
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 personal injury and/or
death, property damage.
CAUTION
When the furnace (chimney installation) is vented
together with other combustion appliances such as a
water heater, the allowable venting materials (L-Vent,
etc.) for use with those appliances must be investigated.
Flue pipe sizing
The following table is an excerpt from the Installation Code and
indicates the permitted flue sizes and minimum base temperat ures for
circular flues in chimneys with thermal resistance of less than R6 (6 ft
•hr •°F / Btu). Where a new appliance, burner, or chimney is installed,
chimney vent sizes and maximum flue ga s te mp erat ur e s (me a sur ed at
the chimney connector with the barometric damper shut, after 5
minutes of operation) shall comply with Table 2.
Note: Thermal resistance values for typical chimneys
are as follows:

1.4.3) Side-wall venting - DV-2000™
Direct Vent System
The furnace can be side-wall vented without the use of a side-wall
power vent, using the new DV-2 000™ venting system with the high
static pressure Beckett AFII and Riello 40-BF oil burners. Outdoor
combustion air must be directly conn ected to the burner or the
DV-2000™ venting system will not function.
The notable characteristics of the DV-2000™ system are as follows:
a) Certi fied to use the following materials for d ucting 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 (152.4 mm
into the side-wall, and the terminal is designe d 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
d) The intake and vent circuits within the te rminal can be accessed
for cleaning.
There are 3 main components to the DV-2000™ system: the VTK vent
terminal kit, the IFV insulated flexible venting material and the
field-supplied 3 inch PVC or ABS intake piping.

DV-2000™ – Vent terminal kits
445 01 4024 05
The certified standard vent termi nal kit is Mod el No. VTK-1 for models
ODH5-F and OCF105A12B and is suitable for installation in walls up
to 0.3 m (14") thick. Both kits contain the following items to complete
the hook-up to the venting and furnace:
Qty Description
1 Terminal
2 Sealing clamps
1 Side-wall venting breach plate
2 Sealing strips
1 Inner wall plate
1 Pressure control with tubing
2 Insulated quick-connect terminals
3 Stainless steel screws
6 Self tapping stainless steel screws
Insulated flexible venting - DV-2000™
The certified venting materials come in 3 l engths, Model No. IFV 3-15,
IFV3-23 and IFV3-30 and correspond t o 4.6 m, 7.0 m, and 9 .1 m (15',
23' and 30') of continuous lengths of ve nt. The vent construction is
coaxial and incorporates a stainless steel corrugated flexible liner
surrounded by a thick blanket of insulation and covered with an o uter
layer of flexible corrugated aluminium sle eve to protect the insulation .
Splicing vent lengths together is prohibited. The minimum and
maximum continuous vent lengths permitted for installation are:
1.5 m (5') minimum 9.1 m (30') maximum
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, which may eventually
perforate the liner and allow vent gasses to enter
the dwelling. This can result in death, personal
injury and/or property damage.

For installations in the U.S.A. refer to Sectio n 6.7.3.4 of t he NFPA
31.
FIGURE 1
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.

Side wall venting installation - DV-2000™
445 01 4024 05
WARNING
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 breach - DV-2000™
1. Remove the standard breach plate by removin g the brass nu ts;
2. Determine which direction the venting will be routed from the
furnace and then install the special side-wall venting breach plate
provided in the VTK Series vent kit so that the breach plate test
port will be accessible after vent installation. However, do not
install the breach plate with the test port pointing downward.
Tighten the brass nuts;
3. The flexible venting h as 4 pieces of corrugated spin sleeve that
has been temporarily screwed on over top of it . Remove t he spin
sleeve completely by unscrewing it in a counter-clockwise
direction;
4. Using tin snips, cut t he aluminium outer sleeve back by 127.0
mm (5") on the IFV Series vent (see Figure 1.1). Ensure the
snips are well adjusted and sharp or th e cut end of the venting
will be too jagged to start the threads of the spin sleeve (see
Figure 1.1);
5. Prepare the furnace breach end of the i nsulated fle x vent by first
screwing the spin sleeve onto the corrugated aluminium jacke t
(see Figure 1.2) until the trailing edge of the s pin sleeve is about
0.3 m (12") from the end of the vent (see Figure 1.3);
6. Pull the insulatio n back to expose the corrugated s tainless steel
core;
7. Cut th e corrugated stainless steel core b ack by 76.2 mm (3") on
the IFV Series vent. You should now have about 76 .2 mm (3") o f
insulation hanging out past the stainless steel core (s ee Figure
1.4);
8. Push the stainless steel core ont o the b re ach 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 space d
around the circumference of the s tainl ess st eel c o r e, sta rtin g with
the first screw at top dead centre. Start the drill point of the
screws in the valleys of the corru gations at 9.5 mm –15.8 mm
(3/8”-5/8”) back from the end of the s tainless steel core, so the
screw heads can be properly sealed in the forthcoming
operations (see Figure 1.6);
9. With the stainless steel core no w firmly attached to the breach,
tear off one green gum-sealing str ip from the backing. Wrap the
seal strip around the joint, always keeping the centreline of the
seal strip over the line where the corrugate d stainless steel core
makes the transition to the smooth oute r surface of the breach
pipe. In other words, the seal strip must be ce nt re d over t he j oin t.
After wrapping the seal strip around once, allow 12.7 mm (1/2”)
overlap and tear off the residual length (see Figure 1.7);
10. Break the residual length of seal strip into 3 equal parts a nd stuf f
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 t he breach lines up
with the edge of the gum seal 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 hea d of the draw clamp (see
Figure 1.8). Tighten the band cla mp with considerable torque to
cause the gum seal to be squeezed i nto all crevice s and to ooze
out of the end of the clamp closest to the breach (see Figure 1.9).
The gum will eventually become rubbery;
12. The seal is permanent and should never need to be
disconnected as the breach plate can be r emoved for cleaning
and inspection using the 4-bolt joint;
13. Tuck the vent insulation into the breach collar;
14. Screw the spin sleeve tightly into the breach c ollar 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);
15. Bend the venting into the desired radius coming off the breach.
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 jacke t
until the trailing edge of the spin sleeve is about 254.0 mm (10")
from the end of the vent;
2. Using sharp tin snips, c ut the aluminium outer sleeve back by
127.0 mm (5") on the IFV Series vent;
3. Pull the insulatio n back to expose the corrugated s tainless steel
core;
4. Cut th e corrugated stainless steel core b ack by 76.2 mm (3") on
the IFV Series vent. You should now have about 76 .2 mm (3") o f
insulation hanging out past the stainless st eel 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 sho uld be equally
spaced around the circumference of the stainless steel core,
starting with the first screw at top dead centre. Start the d rill point
of the screws in the valleys of the corrugations at 9.5 mm-15.8
mm (3/8”-5/8”) back from the end of the stainless steel core;
6. With the s tainless steel core now firmly at tached to the terminal,
tear off the other green gum-sealing strip from the backing. Wrap
the seal strip around the joint, al ways keeping the centreline of
the seal strip over the line whe re 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
12.7 mm (1/2”) overlap and tear off the residual length;
7. Break the residual length of se al strip in to 3 e qual parts and s tuff
them onto the screw heads of the stainless steel self-drilling
screws so that the screw heads are completely covered;
8. Position the o ther stainless steel band clam p 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 t orque to cause the
gum seal 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
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.
