insulation and blast tube. If additional rope gasket is not provided with the burner, use 3/8” fiberglass rope rated for 2300°F (provided by others).

Reinstall burner mounting plate when finished.

CAUTION

Failure to properly fill all gaps between the insulation and burner blast tube may result in damage to the burner.

5.For boilers without tankless heaters, proceed to Paragraph H (Install Steam Trim) or I (Install Water Trim).

6.For boilers with tankless heaters, install the tankless heater manifolds according to Figure 36.

H.STEAM BOILERS — INSTALL STEAM TRIM

Items for steam trim are located in the steam trim carton (except for the separately ordered low water cutoff and tankless heater control). Figure 24 shows the proper tappings for each item.

1.Install the gauge glass set.

2.Install the low water cut-off. Follow manufacturers instructions furnished with control.

3.Install the pressure limit control using the ¼” x 90 (1-7/8” x 4”) extended leg syphon and the ¾” NPT x ¼” FPT hex bushing.

NOTICE

The L404 Pressure Limit contains 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.Level the pressure limit control by carefully bending the syphon until the control’s leveling indicator hangs freely with its pointer directly over the index mark inside the back of the case.

5.Install the steam gauge using the ½” NPT x ¼” FPT hex bushing.

6.Install the safety valve as shown in Figure 38a. Safety valve must be installed in vertical position.

7.For boilers with tankless heaters, install the operating control in an unused tapping through one of the heater plates.

WARNING

Safety valve discharge piping must be piped to within six (6) inches of floor, or to floor drain to eliminate potential of severe burns. Do not pipe in any area where freezing could occur. Do not install any shut-off valves, plugs or caps in discharge piping.

8.Plug extra boiler tappings.

9.Install required bottom blowoff/drain valve and connecting piping (supplied by others) per minimum piping requirements for steam boilers. See Figure 32.

I.WATER BOILERS - INSTALL WATER TRIM

Items for water trim are located in the water trim carton (except for the separately ordered low water cutoff and tankless heater control). Figure 24 shows the proper tappings for each item.

1.Install the temperature pressure gauge.

2.Install the low water cutoff. Follow manufacturers instructions furnished with control.

3.Install the immersion well and mount the aquastat (limit control) onto the well.

4.Install the pressure relief valve as shown in Figure 38b. Relief valve must be installed in vertical position.

5.Plug extra boiler tappings.

6.Install required bottom blowoff/drain valve (supplied by others) per minimum piping requirements for water boilers, see Figure 26.

WARNING

Relief valve discharge piping must be piped to within six (6) inches of floor, or to floor drain to eliminate potential of severe burns. Do not pipe in any area where freezing could occur. Do not install any shut-off valves, plugs or caps in discharge piping.
