DIRECT VENTING OF OLSEN OIL FIRED FURNACES
1. DIRECT VENTING OF OLSEN OIL FIRED FURNACES
• Installation shall be done by a “Qualied Installer".
“Qualied Installer” shall mean an individual who has been
properly trained or is a licensed installer.
• The UML oil red furnaces with suxes NXU for Beckett's
NX , and RBU for Riello’s 40BF series oil burners, are
certied for venting through the wall using ducted outdoor
air for combustion.
• The Direct Vent series is ideal for applications where a
conventional chimney is unavailable, nor easily installed;
an electrically heated home being retrot for oil forced air
heating for example.
• The term Direct Vent refers to a sealed combustion
system.
• Direct vented appliances require some foresight and
planning, since the range of ue lengths is restricted,
clearances are critical, and national and local codes are
quite strict with respect to safety. Be sure that the furnace
can be installed within the physical limitations of the
home, and in accordance with local codes and regulations.
• Physical limitations include practical issues such as
sucient clearance to grade. It is advisable to install
the vent termination in an area sheltered from winter
prevailing winds. Avoid vent termination locations subject
to frequent strong wind gusts.
• It is the installer's responsibility upon installation and the
user's responsibility during subsequent operation to ensure
that gases issuing from the vent terminal do not cause a
hazard through contact with adjacent naturally occurring
combustible materials.
• It is the homeowner's responsibility to ensure the area
around the vent terminal and air intake is free of snow,
ice and debris. Check the vent terminal during heavy
snowstorms to ensure proper operation.
• In extremely cold climates, ice may have to be removed
from the vent terminal on a regular basis.
• B-VENT SHALL NOT BE USED IN THE VENT SYSTEM.

• Less than 1 foot (0.3 m) above grade.
• Less than 1 foot (0.3 m) from the sot of the roof of the
structure.
• Less than 3 feet (0.9 m) from the inside corner of an L
shaped structure.
• Less than 5 feet (1.6 m) from a gas regulator vent outlet,
or oil tank vent outlet.
3. VENT TERMINAL INSTALLATION
This applies to the standard 28972 Direct
Vent Oil Vent Terminal. See Figure 1.
Select the location of wall penetration that conforms to
the code for exterior location, as close to the appliance as
possible, maintains clearance to combustibles and where the
minimum 1/4-inch per foot slope back to the appliance can be
maintained.
• Cut 6-1/2” diameter hole through the wall.
• Remove the Intake Air Sleeve from the Terminal.
• Insert Terminal through the wall from outside, secure
with 4 screws to the wall, seal to wall with weatherproof
sealant.
• From inside the building, reattach the Intake Air Sleeve
and secure inner sleeve to outer sleeve with 2 screws.
Use 4 screws to secure Sleeve to the wall. Ensure the
Intake Air Connector is located for ease of attachment and
complies with code.
4. VENT TERMINAL RISER KIT
The 29231 Vent Terminal Riser Kit has been designed to
increase the height above grade level of the Vent Terminal
by approximately 3 feet. See Figure 5 for typical Vent Riser
setup. This is ideal where excessive snow build up could occur
or where more exibility is required to maintain minimum
clearances to grade.

5. DIRECT VENT INTAKE AIR PIPE INSTALLATION
NOTICE
Flexible duct for combustion air use is not
permitted.
IMPORTANT: OUTDOOR AIR FOR COMBUSTION MUST BE
USED.
The oil burners approved for use with ducted outdoor air
for combustion are Beckett NX , Riello 40BF. All units obtain
outdoor air by the following means:
Acceptable combustion air intake materials:
1.
4-inch “C” Vent (single wall galvanized).
2.
4-inch Rigid Aluminum pipe (0.030” wall thickness).
3.
Beckett NX burners, are furnished with a 4” diameter
straight combustion air intake collar for connecting eld
supplied 4” combustion air intake pipe to the burner. The
intake collar is equipped with a hose tting for connecting
the negative pressure side of the blocked vent safety
switch (pressure switch).
4.
Riello 40BF3/BF5 burners are furnished with a 3” diameter
straight combustion air intake collar and a 3” diameter
90° elbow combustion air intake collar. Both intake
collars are equipped with hose ttings for connecting the
negative pressure side of the blocked vent safety switch
(pressure switch). Use whichever intake collar (straight
or elbow) is most convenient depending on the furnace
position (upow/downow/horizontal). Typically the elbow
must be used in upow installations to avoid the intake
air pipe interfering with the vent pipe. Riello burners are
also furnished with a 3” to 4” increaser tting and a 3"
diameter plain elbow (without hose tting). The increaser
tting connects to the intake collar for connecting eld
supplied 4” combustion air intake pipe to the burner. The
plain elbow is for other furnace models and is not used
with the UML.
IMPORTANT: Intake pipe and ttings should be sealed
with foil tape, duct tape, or silicone caulking and
attached mechanically with screws.
Figure 5 - Vent Riser
Maximum combustion air intake length is 25 feet using 8
90° elbows. Venting installation dictates the length from
termination cannot be further than 20 feet; therefore any
longer piping for combustion air intake would be unnecessary.
Combustion air intake does not have minimum length.
Condensation may become a problem during some climatic
conditions. It may be necessary to wrap a portion, or entire
intake piping (particularly metal intake piping) with waterproof
insulation material.

PN 240011300, Rev. G [10/01/2021]
CAUTION
Use appropriate safety precautions! Wear protective
gloves. Thin metal edges are extremely sharp if not
avoided, could result in minor or moderate injury.
7. BLOCKED VENT SAFETY SWITCH MOUNTING AND
PRESSURE TUBING CONNECTIONS
WARNING
Failure to properly install the blocked vent safety
switch could result in death or serious injury.
!
The blocked vent safety switch and associated pressure switch
tubing are shipped loose with the furnace. The pressure
switch must be mounted in the correct location on furnace ue
collar, which varies depending on furnace orientation (upow/
downow/horizontal). See Figure 7.
• Conrm the pressure switch is part number 240011288
with 0.50" W.C. set point.
• Mount the pressure switch in the correct location on the
ue collar assembly according to Figure 7 using two #8
x ½” sheet metal screws provided with the switch. See
Figure 6.
• Connect the 6.5” long black high temperature tubing
from the positive pressure port (the black port) on the
pressure switch to the hose barb on the appliance vent
adapter. If the appliance vent adapter and pressure switch
are properly located, the 6.5” tubing should be just long
enough to be installed with no dips or sags. It should be
uphill all the way to the pressure switch. This prevents
condensation from collecting in the tubing. See Figure 7.
• Connect the 30” grey pressure switch tubing from the
negative pressure port (the grey port) on the pressure
switch to the hose tting on the burner combustion air
intake pipe. This tubing can be cut shorter if desired for
convenience. It is not necessary to avoid dips or sags with
this tubing. See Figure 7.
• Connect the two yellow low voltage wires from the burner
to the pressure switch terminals.

VENT CLEARANCE TO COMBUSTIBLES: ONE (1) INCH.
WARNING
Fire, asphyxiation hazard. Do not enclose vent.
Do not route vent through walls, oors or ceilings.
Improper installation could result in death or serious
injury.
!
INSTALLATION OF "INSULATED DOUBLE WALL FLEXIBLE
VENT”.
The inner pipe is constructed of 4 inch 316 stainless steel, with
a two-ply aluminum outer pipe. High temperature insulation
separates the inner and outer ex pipes. Refer to Figure 10.
IMPORTANT: The venting and vent terminal are
dedicated to the furnace only; do not attempt to vent
any other appliance through it.
Install venting as follows. Installation shall comply with
CAN/CSA B139 Installation Code for Oil Burning Equipment
(Canada) or NFPA 31 Standard for Installation of Oil Burning
Equipment (United States), and / or with local codes and
regulations.
A. In as short and straight a run as possible without any
unnecessary bends.
B. There should not be any dips or sags throughout the full
length of vent.
C. Connector or vent should be sloped upwards from the
appliance at least 1/4” per foot.
D. Do not bend the connector or vent more than 90
degrees.
E. Vent may be cut to minimum of 5 feet in length using
ne tooth (24 teeth per inch) hacksaw blade.
F. Male and female ends of appliance adapters and
connectors must be cleaned with residue free brake
cleaner solvent.
G. Apply minimum 1/4” bead of Si-Ultra Copper Sealant
provided, onto outside of male end of vent to appliance
connector. Fit connector to vent by threading it counter-
clockwise until it stops. Ensure joint is not cross-
threaded.
H. IMPORTANT: The orientation of the appliance
adapter (where vent pipe connects to furnace) is
critical to correct operation of the blocked vent
safety switch. Apply minimum ¼” bead of same
sealant as mentioned above onto female end inside of
appliance connector. Slip connector over end of furnace
ue collar until it stops. Orient the combustion sample
test port and pressure switch hose tting per Figure 7
according to the furnace position. Tighten attached gear
clamp.
I. Support Vent every 36” to prevent sagging.
J. Attach Terminal Connector as described in steps G and H
listed above.
K. Maximum vent length is 20 feet (using a 20 foot vent
kit) Piecing vent kits together (i.e. using 2 ten foot kits
is strictly prohibited).

8. OIL BURNER SET UP
• Shut o electrical power to the furnace.
• Install an oil pressure gauge to the pressure port on the oil
pump.
• Set up the burner for initial ring as indicated in:
º Chart 1 for Beckett NX burners
º Chart 2 for Riello 40BF burners
• Refer to oil burner instructions provided with furnace
documents envelope for specic information concerning
burner adjustment, operation and troubleshooting.
• See gure 8, or 9 as applicable for proper air adjustment
technique.
• Restore electrical power to furnace.
• Start the furnace and bleed all air from fuel oil lines.
• Close purge valve and re the unit.
• Allow the furnace to warm up to normal operating
temperatures. During this time set the pump pressure in
accordance with Chart 1 or 2 as applicable.
• Combustion must be checked with intake air piping
connected for 100% outdoor combustion air to burner.
Length of intake air piping and outside air temperature will
aect the combustion readings.
º For Riello burners the standard burner cover must be in
place on the burner to insure 100% outdoor air.
º For Beckett NX burners, the intake air pipe is
congured such that 100% outdoor air is achieved
either with or without optional burner cover.
• Determine the Desired CO2 Setpoint:
º Combustion air temperature variations will aect how
much air enters the burner. Colder air is denser, so
contains more air per unit volume. More air enters the
burner when the combustion air is cold. Combustion
air temperature must be taken into consideration when
setting up the burner to account for these variations.
º When the furnace has reached steady state (after
approximately 10-15 minutes), remove the bolt from
the test port in the appliance connector. Set the
combustion air to obtain a TRACE of smoke.
º Using suitable combustion test instruments, measure
the Trace Point CO2 at the test port.
º Calculate CO2 Setpoint A = Trace Point CO2 minus
1.5% and enter it here:
Setpoint A: _______________
EXAMPLE: Assume Trace Point CO2 = 13.0%
Setpoint A = Trace Point CO2 minus 1.5% = 13.0%
minus 1.5% = 11.5%
º Measure the incoming combustion air temperature.
º Using Chart 3, determine Setpoint B for the measured
incoming combustion air temperature (choose the
midpoint of the range) and enter it here:
Setpoint B: ________________
Figure 8 - BECKETT NX AIR/HEAD SETTING
• Loosen splined nut on nozzle line about one turn.
• Turn air adjustment screw clockwise to increase air and
counter clockwise to decrease air.
• Retighten splined nut after obtaining proper settings.
º The Desired CO2 Setpoint is the lower of Setpoint A or
Setpoint B. Enter it here:
Desired CO2 Setpoint: _____________________
• Open the air setting to introduce additional excess air to
reduce CO2 to the Desired CO2 Setpoint.
• Smoke reading should be ZERO. If not, increase air to
obtain ZERO smoke.
• Lock the air setting.
• Recheck smoke and combustion.
11
PN 240011300, Rev. G [10/01/2021]
• To adjust the initial air damper setting, remove the burner
cover and turn the air damper adjustment screw (2)
until the top edge of the air damper (3) is in line with the
corresponding number from Chart 2.
• Further adjustments must be made with the burner cover
in place by removing the plastic plug on the cover.
• Turn the screw clockwise to increase combustion air or
counter clockwise to decrease combustion air.
• When proper combustion and smoke spot readings are
achieved, reinsert plastic cap over air adjustment hole.
Figure 9 - RIELLO 40BF AIR DAMPER
NOTICE
Variations in CO2, smoke and temperature readings
will be experienced with Riello burners when burner
cover is in place. Burner cover must be in place
when making measurements to ensure proper test
results.

10. BLOCKED VENT SAFETY SHUT OFF SYSTEM
Each direct vent furnace is equipped with a Blocked Vent
Safety shut o system (BVS). This safety circuit will shut the
burner o in the event of a combustion air blockage or venting
blockage.
The components of this BVS consist of a pressure switch. The
BVS is wired in series with the low voltage T-T connection on
the oil primary control.
11. SEQUENCE OF OPERATION
1.
Room temperature drops, thermostat calls for heat.
2.
Pre-purge begins, lasting 5 to 15 seconds.
3.
Oil solenoid energized
4.
Oil Solenoid opens allowing oil to reach the Burner
Electrodes. Burner ignition begins.
5.
Cad cell detects light from combustion, disconnects the
primary control safety circuit, allowing combustion to
continue.
6.
After 15 to 45 seconds (depending on primary control
characteristics), the electric spark across the electrode tips
stops, combustion continues.
7.
The furnace blower will start after the programmed fan
on delay as determined by the dipswitch settings on the
electronic fan timer control.
8.
Furnace continues to operate and will eventually reach
"steady state", the point at which the system temperature
stabilizes.
9.
Room temperature rises, thermostat is satised, heating
contacts open.
10.
Oil Solenoid Valve closes, combustion stops, Burner Motor
remains on to complete the Post Purge Cycle. Post Purge
will continue up to 6 minutes depending on the control
switch settings. Factory post purge setting is 30 seconds.
This is recommended setting for typical applications.
11.
The furnace blower will stop after the programmed fan
o delay as determined by the dipswitch settings on the
electronic fan timer control.
12.
Furnace remains idle until next call for heat.
12. FINAL CHECK OUT
Before nal test cycle, carefully examine complete vent system
for leaks.
Verify all safety devices and electrical components have been
set for normal operation. Verify all electrical connections are
tight and wiring is secure.

cause burner to recycle
In the event of vent or combustion air intake blockage, the blocked vent safety switch
(pressure switch) contacts will open, opening the contacts between T and T on the
7505P primary control, as if ending the call for heat. Once the post purge period (burner
motor o delay) ends, the burner motor will shut o and the pressure switch contacts
will re-close, again closing the T-T contacts and starting the burner motor. If the vent or
combustion air intake blockage remains, the pressure switch contacts will open again once
the burner motor is running, and shut the burner motor o. Continuous cycling of this type
indicates vent or combustion air intake blockage.
