If the lower (minimum) input is desired, remove
the nozzle which was factory installed. Locate the
lower (minimum) fi ring rate nozzle that is supplied
loose. Confi rm the nozzle is the proper size and
type for the lower fi ring rate as specifi ed in Table
6. Install the proper nozzle in the burner nozzle
adaptor.
I. INSPECT NOZZLE AND ELECTRODES
/ CHANGE FIRING RATE FOR RIELLO
BURNERS. Refer to Section II, Paragraph M, No. 7,
steps a through g for nozzle installation, electrode and
head setting inspection.
Steam Boilers Only
Packaged V83 - V86 steam boilers are shipped with
the lower (standard) fi ring rate nozzle installed.
Packaged V87 - V89 boilers are provided with one
nozzle, installed in the burner, that provides the
same fi ring rate as the water boiler of the same size.
Inspect the installed nozzle and assure that the
nozzle is the correct size and type as specifi ed in
Table 6 of this supplement.
Water Boilers Only
Packaged V8 water boilers are shipped with the
higher input oil nozzle installed in the burner.
A second oil nozzle for the lower (minimum) fi ring
rate is shipped loose for the V83 - V86 models,
attached to the burner. Select the proper oil
nozzle for the installation. The lower (minimum)
input nozzle will provide greater boiler effi ciency.
However, boiler output will be reduced. Refer
to Table 1B for fi ring rates. If the higher rate is
desired, inspect the installed nozzle and assure that
the nozzle is the correct size and type as specifi ed in
Table 6.
If the lower (minimum) input is desired, remove
the nozzle which was factory installed. Locate the
lower (minimum) fi ring rate nozzle that is supplied
loose. Confi rm the nozzle is the proper size and
type for the lower fi ring rate as specifi ed in Table
6. Install the proper nozzle in the burner nozzle
adaptor.
J. INSTALL SAFETY OR RELIEF VALVE IN
TAPPING "M".
Use ¾" NPT x 8" nipple and/or ¾" NPT coupling
included in trim bag. Safety or Relief Valve must
be installed with spindle in vertical position. Pipe
discharge as shown in Figures 13A, 13B, 13C and
14. Installation of the safety or relief valve must be
consistent with ANSI/ASME Boiler and Pressure
Vessel Code, Section IV.

and syphon included in trim bag. See Figure 9.
1. Do not tighten the limit by holding the case; apply a
wrench to the brass hex below the case.
2. Connect wiring harness from Low Water Cut-Off to

3. Level an L404A pressure limit by carefully bending
the syphon until the limit's leveling indicator hangs
freely with its pointer directly over the index mark
inside the back of the case.
