Riello 40-BF burner:
Fully insert the female end of the 2” 90
°
street elbow
into the combustion air fitting on top of the burner.
Fasten securely with 3 self-tapping sheet metal screws.
Cement the 2” end of the 3” female to 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 combustion air fitting.
The fitting will have to be silicone sealed as the fit is a
bit loose. Fasten securely with 3 self-tapping sheet
metal screws.
Terminal connection:
Insert the 3” 90
°
female-female elbow onto the stainless
steel air intake fitting located on the right side of the
vent terminal (viewing from the rear). Fasten securely
with 3 self-tapping sheet metal screws.
Intermediate piping:
Pipe as required 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 sections 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”,
whereas Septic Sewer Pipe has a typical outside
diameter of 3.25”.
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 follow
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 the burner
level must employ a two pipe fuel supply system with an
appropriate fuel pump (more than 8’ lift use 2 stage
pump and more than 16’ an auxiliary pump).
Follow the pump instructions to determine the size of
tubing you need in relation of the lift, or the horizontal
distance.
7)
BURNER INSTALLATION
Mounting the burner:
a. The warm air furnace burner mounting plate has a
four bolts configuration.
b. Position the mounting gasket between the mounting
flange and the appliance burner mounting plate.
Line up the holes in the mounting flange with the
studs on the appliance 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 polarity
Checking the polarity:
The oil burners used on the furnaces have solid state
control systems which makes them sensitive to the
proper connections of the hot and neutral power lines.
The controls will be damaged if the two lines are
reversed.
a. Set your voltmeter to line voltage.
b. Place one prong on your grounded electric entry
box and one prong on the black wire.
c. Read the voltage.
d. If the voltage is zero, check the white wire. If line
voltage shows. Reverse the 115-volt leads entering
the furnace junction box.
