If the lower (minimum) input is desired, remove the nozzle which was factory installed. Locate the lower (minimum) firing rate nozzle that is supplied loose. Confirm the nozzle is the proper size and type for the lower firing rate as specified 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) firing rate nozzle installed. Packaged V87 - V89 boilers are provided with one nozzle, installed in the burner, that provides the same firing 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 specified 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) firing 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 efficiency. However, boiler output will be reduced. Refer

to Table 1B for firing rates. If the higher rate is desired, inspect the installed nozzle and assure that the nozzle is the correct size and type as specified in Table 6.

If the lower (minimum) input is desired, remove the nozzle which was factory installed. Locate the lower (minimum) firing rate nozzle that is supplied loose. Confirm the nozzle is the proper size and type for the lower firing rate as specified 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.

WARNING

Safety or relief valve discharge piping must be piped near floor to eliminate potential of severe burns. Do not pipe in any area

where freez ing could occur. Do not install any shut-off valves, plugs or caps.

K.PACKAGED BOILERS WITH PROBE STYLE LWCO. Install Limit in Tapping "A" using ¾" NPT x 2" nipple, ¾" NPT elbow, ¾" NPT x ¼" NPT bushing, 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 steam pressure limit.

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.

NOTICE

L404A Pressure Limits contain mercury in a sealed tube. Do not place limit in the trash at the end of its useful life.

If this limit is replacing a limit that contains mercury in a sealed tube, do not place your old limit in the trash.

Contact your local waste management authority for instructions regarding recycling and the proper disposal of this limit, or of an old limit containing mercury in a sealed tube.

If you have questions, call Honeywell Inc. at

1-800-468-1502.

4.An L404F pressure limit does not require leveling.
