BURNER SETUP & BOILER OPERATION
A. BURNER INSTALLATION
1. The oil burner is supplied with a mounting flange
fixed in position.
2. Mount the burner to the Burner Mounting Plate
(Item 4) with four (4) 5/16” studs and nuts provided.
3. Care must be taken when routing the oil lines so
not to interfere with the opening and closing of the
burner mounting plate. Flexible oil lines or flared
copper disconnects with valves (when copper lines
are used) may be installed to assure full opening of
the burner mounting plate when servicing.
4. Oil burner specifications:
For information pertinent to the oil burner such
as nozzle sizing, fuel supply piping, adjusting or
servicing, refer to the charts in this section and the
burner installation manual.
Riello burners - certain models use common burners
across multiple boiler sizes. As required replace
installed nozzle with loose nozzle provided and adjust
settings.
B. BURNER START-UP & ADJUSTMENT
1. Burner should start automatically when thermostat
is turned up and main boiler service switch is turned
on. If burner does not start, check to be sure there
is oil in the tank and push reset button on burner
control:
Beckett: Square red button.
Carlin: Round red button.
Riello: Round red button inside clear flexible
cover on back of burner cover.
If burner still does not start, contact serviceman.
2. Adjust burner and barometric draft control for
highest CO
²
(Maximum 13.1% [EC(T)-e-03 -
EC(T)(-e)-05] or 12-1/2% [EC(T)-06]) while
maintaining a 0 Smoke and a minimum of
-.01” W.C. draft overfire.
All adjustments must be made using suitable
instruments such as found in a Bacharach
Combustion Test Kit.
3. Burner and boiler can be shut down by turning
down the thermostat and moving the main boiler
service switch to the “off” position.
4. See burner manufacturer’s manual for further
information regarding the burner.
C. CHECK BOILER CONTROLS
1. Limit and Operating Controls:
a. Lower the set point of each control until the
burner shuts down. Note that the system pressure
(or temperature) corresponds to the desired set
point.
b. Return the controls to the desired set point.
2. Low Water Cut-off - consult the manufacturer’s
instructions for the low water cut-off operational
check procedure.
D1. FILL THE BOILER (WATER BOILERS)
1. Set the air pressure on the expansion tank to the
system water pressure before installing. The pressure
reducing valve on the fill line will typically allow the
system to be filled and pressurized to 12 psi
(83 kPa). Consult the valve and expansion tank
manufacturer for more specific information.
2. Fill the boiler and system with water making certain
to vent air from all high points in the system. Water
should bleed from each air vent when it is opened.
3. Check all joints and fittings throughout the system for
leaks. If leaks are found, drain the system and repair
as required.
4. If the water hardness is high, use water treatment to
reduce the deposition of minerals in the boiler.
5. If the water pH is out of 7.5 to 11 range, add
water treatment chemicals to bring within range, if
required.
6. If the system requires antifreeze protection, use only
propylene glycol specially formulated for hydronic
systems. These contain inhibitors that prevent
5. BURNER SETUP & BOILER OPERATION
Burn only #2 Fuel Oil in this appliance. Do not use
gasoline, crankcase drainings or any oil containing
gasoline.
CAUTION
Be sure hi temp gasket is between the burner
mounting flange and the Burner Mounting Plate.
NOTICE
Two-pipe oil supply for Riello burner requires a
separate kit. Order part #C7001026 from
Riello dealer.
NOTICE
Do not attempt to start the burner when excess oil
has accumulated, when the unit is full of vapor, or
when the combustion chamber is very hot.
CAUTION
Do not start the burner unless all cleanout doors
are in place.
