special connections is provided. For wiring
requirements, refer to Section VIII: Electrical and
appropriate wiring diagram.
D. Install Trim and Controls
Refer to appropriate paragraphs (following) for trim
and controls to be installed.
1. Steam Boiler with Probe Low Water Cutoff
a. Install pressure limit control into Tapping "H"
with siphon, ¾" x ¼" hex bushing, ¾" elbow and
¾" x 3" nipple provided. See Figures 1 and 2.
DO NOT TWIST CONTROL. Use wrench on
hex tting located at bottom of control. See
Figure 18.
b. The L404F pressure limit employs a snap action
switch and does not require leveling. See Figure
18.
c. Install pressure gauge into Tapping "B" (½ NPT
bushed to ¼ NPT). See Figures 1 and 2. Tighten
with wrench applied to square shank on back of
gauge. DO NOT APPLY PRESSURE ON
GAUGE CASE since this may destroy
calibration of gauge.
d. Install Low Water Cutoff Probe into Tapping "K"
(¾ NPT). HANDLE PROBE WITH CARE.
e. Attach Low Water cutoff Control to Probe by
following instructions packed with control.
f. Install gauge glass ttings into Tappings "C"
(½ NPT). See Figures 1 and 2. Lower tting has
small drain valve.
g. Install gauge glass and protective rods in ttings.
h. Attach "Lowest Permissible Water Level" Plate
with sheet metal screws in location indicated in
Figure 9.
i. Attach "Frequent Water Addition" Label above
