Riello manometers and vacuum gauges do not require any adapters, and can be safely connected to the pump ports. An NPT x metric adapter must be used when connecting other gauge models.

g.Replace Burner Cover and Tighten Burner Cover Screws.

Water Boilers Only

Select the proper oil nozzle for the installation. Burners for knockdown V8 water boilers are shipped with the high (standard) 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. Either nozzle may be used with water boilers. 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 of this manual. The nozzle input is stamped on the hex flat of the nozzle.

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 of this manual. Install the proper nozzle in the burner nozzle adaptor.

Proceed to Step c for burner drawer assembly removal.

N.INSTALL TRIM AND CONTROLS WITH BECKETT BURNER. - Steam Boiler Only (see Figures 1D & 5).

1.Thread the pressure gauge into the ¼” NPT tapping "B", of the front section. Tighten with wrench applied to the square shank of the gauge.

CAUTION

Do not apply pressure to the gauge case - this may result in inaccurate readings.

2.Thread 1½” NPT x ¾” NPT bushing and a ¾” NPT drain valve into the 1½” NPT tapping located in the lower right corner of the front section. Tighten with wrench.

NOTICE

Lower rear section Tapping "H" is used for standard condensate return on steam boilers.

3.Thread safety valve, as shown in Figure 1D, into ¾" NPT coupling and ¾” NPT x 8” nipple previously installed in Paragraph H, No. 1, step b. Tighten with wrench. Pipe discharge as shown in Figure

14. Installation of the safety (relief) valve must be consistent with ANSI/ASME Boiler and Pressure Vessel Code, Section IV.

WARNING

Safety 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.

4.Install probe type Low Water Cut-Off (LWCO) if so equipped.

WARNING

Read the manufacturer’s instructions packed with the probe LWCO for proper pipe dope application. DO NOT use Teflon tape on probe threads. Use of teflon can render the probe LWCO inoperational.

a.Thread probe into ¾” NPT tapping "C" located on the front section, down and to the right of the pressure gauge. Slip the low water cut-off (LWCO) control over the probe and clamp in place. Connect the wire(s) between the probe and control per the manufacturer’s instructions.

b.Install the gauge glass using the two ½” NPT tappings to the right of the probe LWCO.

5.Install float-type LWCO, if so equipped. See Figure 8.

a.Install nipples and unions in "D" Tappings.

b.Mount hardware to low water cut-off body. Install assembly.

c.Install water gage glass on low water cut-off assembly's tee fittings.

6.Install Pressure Limit Control.

a.Float LWCO only: Remove ¼" NPT plug from top of Low Water Cut-Off. Install Syphon and Limit into this tapping. See Figure 8.

b.Probe LWCO only: Install Limit in Tapping "A" using ¾" NPT x 3" long nipple, ¾" NPT elbow, ¾" NPT x ¼" NPT bushing, and syphon. See Figure 9.

c.Do not tighten the limit by holding the case; apply a wrench to the brass hex below the case.

d.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.
