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). Figures 25a and 25b show the

proper tappings for each item.

1. Install the gauge glass set.

2. Install the low water cut-off. Follow manufacturer’s

instructions furnished with control.

3. Install the pressure limit control as shown in Figure

25b.

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 Figures 25a

and 40a. 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.

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

25b.
