INSTALLATION PRECAUTIONS
AIR FOR COMBUSTION
Do not install burner in room with insufficient air for combustion. Be sure there is an adequate air supply for
combustion if the boiler/furnace room is enclosed. It may be necessary to create a window to permit suffi-
cient air to enter the boiler/furnace room. The installer must follow local ordinances in this regard.
CANADA It is suggested that the installer follow CSA standard B139.
USA It is suggested that the installer follow NFPA manual #31.
CHIMNEY
Be sure chimney is sufficient to handle the exhaust gases. It is recommended that only the burner be con-
nected to the chimney. Be sure that it is clean and clear of obstructions.
OIL FILTER
An external oil filter is REQUIRED, even though there is an internal strainer in the pump. The filter should be
replaced at least once a year, and the filter container should be thoroughly cleaned prior to installing a new
filter cartridge.
DRAFT
Follow the instructions furnished with the heating appliance. The pressure in the combustion area should be
kept as close to zero as possible. The burner will operate with a slight draft or pressure in the chamber.
ELECTRICAL CONNECTIONS
CANADA All electrical connections should be done in accordance with the C.E.C. Part 1, and all local codes.
The system should be grounded.
USA All electrical connections should be done in accordance with the National Electrical Code, and all
local ordinances. The system should be grounded.
CONTROL BURNER OPERATION
Check out the burner and explain its operation to the homeowner. Be sure to leave the Owner’s Instruction
sheet with the homeowner.
FIRE EXTINGUISHER
If required by local codes, install an approved fire extinguisher.
ELECTRICAL CONNECTIONS
In most localities, a number 14 wire should be used inside a metal conduit. The system should be grounded.
A service switch should be placed close to the burner on a fireproof wall in an easily accessible location.
The burner settings used in this manual were obtained under laboratory conditions and may vary
from those obtained in the actual installation of the burner. Combustion results must be verified
using proper combustion test equipment. Riello will not be responsible for the improper
installation or set-up of the appliance.

A) Insert the two BOLTS (1) into the UNIVERSAL MOUNTING FLANGE (10) from the flat side, ensuring the bolt heads
are flush with the flat surface. Secure in place using two special CHROME NUTS (2) provided.
B) Position the MOUNTING GASKET (3) between the flat surface of the UNIVERSAL MOUNTING FLANGE (10) and
the appliance.
Line up the holes in the UNIVERSAL MOUNTING FLANGE with the STUDS (4) on the appliance mounting plate
and securely bolt the UNIVERSAL MOUNTING FLANGE to the plate.
C) Secure the two semi-flanges of the ADJUSTABLE COLLAR (9) to the AIR TUBE using the two long BOLTS (6).
Be sure that the ADJUSTABLE COLLAR (9) is properly positioned so the outside edge of the END CONE will be at
least 1/4” inch (6.5 mm) back from the inside wall of the refractory of the combustion chamber (see dimension B
above). The measured length (A) is to include MOUNTING GASKET and FLANGE, if used.
D) The burner may now be attached to the heating unit by insetting the AIR TUBE through the BURNER ACCESS
HOLE (8) and into the appliance, making sure the BOLTS (1) line up with the two HOLES (5) in the ADJUSTABLE
COLLAR (9). Secure the burner in place using two NUTS (7).
A visual verification of the air tube insertion into the combustion chamber of the heating unit is suggested.
Dimension B should be at least 1/4” (see drawing).
NOTE:
A suggested method for creating mounting bolt holes in the mounting gasket: Hold the gasket against the appliance
mounting bolts using the mounting flange for proper positioning. Lightly tap the flange with a hammer to form the holes.
METHOD 2 – SEMI-FLANGE COLLAR
A) Follow item C from METHOD 1.
B) Align the air tube and attached adjustable collar so air tube is centered in the burner access hole of the boiler/fur-
nace unit. Mark the center of the two holes in the ADJUSTABLE COLLAR on to the front plate of the heating unit.
Then drill 1/4 inch (6.5 mm) holes through the front plate of the unit, using marks as a guide.
C) Install two short BOLTS (1) through the front plate of the heating unit from the inside, and secure on the outside us-
ing the two special CHROME NUTS (2).
D) Follow item D from METHOD 1.
METHOD 3 – PEDESTAL MOUNT
Secure the MOUNTING FLANGE to MOUNTING PEDESTAL using the hardware provided with the pedestal. Secure
burner to MOUNTING FLANGE as in METHOD 1, item A, C and D.
NOTE:
It is suggested that the pedestal be anchored in position on the floor by installing brackets over the pedestal tube and
securing brackets to the floor.
WHEN THE COMBUSTION CHAMBER IS LINED WITH A REFRACTORY MATERIAL, IT IS
IMPERATIVE THAT THE END CONE NOT PROTRUDE INTO THE CHAMBER AREA, AS EXCESSIVE
HEAT AT BURNER SHUT DOWN WILL DAMAGE THE END CONE.

AMULET INSTALLATION INSTRUCTIONS
(Required on some models)
The amulets provided have been selected by Riello to protect the
combustion tube from hot exhaust gases and flame. This protec-
tion may be needed in applications where the combustion tube
opening in the combustion chamber refractory is larger than the
tube outside diameter.
The amulet has been sized to fit Riello Model 40 sizes F3 and F5
plus the Riello Model R35.
When installing this amulet, handle it carefully.
Do not exert undue pressure when pushing the amulet over the
combustion tube.
Excessive force can result in a broken amulet!
If the amulet will not fit easily onto the tube, remove a small amount of the inner diameter with a sharp knife to provide
the necessary clearance.
The diagram below shows the proper position of the amulet after installation.

OIL LINE CONNECTIONS
This burner is shipped with the oil pump set to operate on a single line system. To operate on a two-line system
the by-pass plug must be installed.
WARNING:
Do not operate a single line system with the by-pass plug installed.
Operating a single line system with the by-pass plug installed will result in damage to the pump shaft seal.
NOTE:
Pump pressure must be set at time of burner start-up. A pressure gauge is attached to the PRESSURE PORT (8)
for pressure readings. Two PIPE CONNECTORS (6) are supplied with the burner for connection to either a single
or two-line system. Also supplied are two ADAPTORS (3), two female 1/4” NPT, to adapt oil lines to burner pipe
connectors. All pump port threads are British Parallel Thread design. Direct connection of NPT threads to the
pump will damage the pump body.
Riello manometers and vacuum gauges do not require any adapters, and can be safely connected to the pump
ports. An NPT (metric) adapter must be used when connecting other gauge models.
SINGLE LINE (GRAVITY FEED SYSTEM)
A) The burner is shipped configured for use in single line applications. No changes to the oil pump are required for use
in single line applications.
NOTE: If the pump cover (1) is removed for any reason, be sure the O-ring (2), is properly seated in the pump cover
(1) before re-attaching the pump cover to the pump housing.
B) Connect the pipe connector to the SUPPLY PORT(5) of the pump. Attach the NPT adapter to the pipe connector.
Attach the required piping to this pipe adapter. Be sure that the plug in the RETURN PORT (7) is tightened securely.

TWO LINE (LIFT SYSTEM)
A) If a two-line system is required, install the By-pass plug provided. The by-pass plug is installed in the return port
of the pump. A 2.5-mm hexagonal key provided with the by-pass plug is to be used to install the plug.
DO NOT use an inch size hexagonal key; damage to the by-pass plug may result.
When operating on a two-line system, supply and return lines should be the same diameter and both should
extend to the same depth inside the fuel tank. Be sure there are no air leaks or blockages in the piping sys-
tem. Any obstructions in the return line will cause failure of the pump shaft seal.
PUMP PURGE
NOTE: To protect the pump gears, it is advisable to lubricate the pump prior
to purging a lift system. Apply oil through the VACUUM PORT (C).
A) SINGLE LINE (GRAVITY FEED SYSTEM)
I. Loosen the bleeder valve (A) until oil flows out. Tighten the bleeder valve
securely and startburner.
II. When bleeding the pump by pressure:
1) Loosen the bleeder valve (A).
2) Disconnect nozzle oil supply line at the pump nozzleport (B).
3) Attach a flexible plastic tube to the pump nozzle, port directing the oil
flow into a bucket.
4) Loosen the screw(s) securing the air tube cover, allowing it to be re-
moved freely.
5) Holding the air tube cover in its proper location start the burner.
6) When the solenoid valve is engaged approximately 10 seconds after
starting, remove the air tube cover and shine a light source on the
flame sensor, allowing it to see false light.
WARNING:
- Pipe dope or Teflon tapes are NOT to be used on any direct oil connection to the fuel pump.
- The height ‘P’ in Pipe Length Charts should not exceed 13 feet (4 m).
- The vacuum should not exceed 11.44 inches of mercury.
IMPORTANT:
An external, appropriately listed and certified oil filter must be placed in the fuel line between the fuel tank
and the burner pump.
To install the by-pass plug:
1) Remove the return plug (7).
2) Install the by-pass plug (4) using the 2.5 mm hexagonal key.
B) Attach the two PIPE CONNECTORS (6) to the pump SUPPLY and pump RETURN PORTS (5 and 7).
Attach the required piping to these two pipe connectors using the NPT/ METRIC ADAPTERS that are supplied
with the burner.

7) Run the burner until the fuel pump has been purged of air, then tighten the bleeder valve and immediately
shut down the burner.
8) Reinstall the air tube cover and nozzle line.
9) The burner can now be started normally.
WARNING: Omitting steps 2 and 3 will result in a collection of unburned oil in the combustion chamber creating a haz-
ardous situation upon burner startup.
B) TWO LINE (LIFT SYSTEM)
Turn off the main power source to the burner and remove the air tube cover.
Shines a light source on the flame sensor (now visible where the air tube cover was removed), return power to the burn-
er and activate the burner. With the light source in place, the burner will operate in prepurge only. When the pump is suf-
ficiently purged, the hydraulic air shutter will open.
Once the burner is purged, turn off the power source and replace the air tube cover.
Return power to the burner. The burner is now ready to operate.
SETTING THE AIR ADJUSTMENT PLATE
The electronic air shutter assembly (1) is operated on a
120V 60Hz. motor, and the burner motor will not operate un-
til the air shutter is in its fully open position.
Set the air plate (4) setting according to OEM setup informa-
tion or by following the Retrofit settings listed in this manual.
To adjust the air plate (4) to the desired set point indicator
(2), loosen the center air shutter assembly screw (5) and
loosen the side air plate screw (3), move air plate (4) by us-
ing the air plate adjust arm. After adjustments are made
please retighten screws (3) & (5).
The final position of the air adjustment plate will vary on
each installation. Using proper combustion test instruments
to establish the proper setting of the air gate setting to
achieve safe and efficient results according the appliance
information or if not available.
NOTE: Variations in flue gas, smoke, CO2 and temperature readings may be experienced when burner cover is put
in place. Therefore, the burner cover must be in place when making final combustion instrument readings, to ensure
proper test results are obtained.
ATTENTION:
It is important that the fuel line be completely sealed and free from air leaks or any internal blockages.
WARNING! WHEN THE BYPASS PLUG IS INSTALLED, A TWO-PIPE SYSTEM MUST BE USED OR FAILURE OF
THE PUMP SHAFT WILL OCCUR.
