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.
