D. Gas Valve Installation
1) The gas valve assembly has been pre-piped with one half of a piping union and is to be connected to the other half
of the union located on the gas manifold.
2) Connect the pilot tubing from the pilot burner to the gas valve pilot tapping.
3) Connect the thermocouple lead to the gas valve (standing pilot boilers only).
E. Control and Trim Installation
(Refer to Figure A3 for Tapping Locations)
1) Install the pressure limit control into tapping “H” with the siphon. A ¾” x ¼” bushing has been factory installed.
Do not twist or otherwise bend the control upon installation.
2) Install the pressure gauge into tapping “B”. A ¾” x ¼” bushing has been factory installed. Tighten with wrench
applied to the square shank on the back of the gauge. Do not apply pressure on the gauge case since this may ruin
the calibration of the gauge.
3) Steam boiler with McDonnell Miller #67 float Low Water Cutoff
a) Install the low water cutoff per the instructions packed with the control.
b) Screw brass nipples with one side of the brass union into tappings “C”.
c) Attach the gauge glass / low water cutoff assembly to the other side of the brass union.
d) If not already present on the jacket, attach the blow-down card to the left side jacket panel, just above the “Lowest
Permissible Water Level” plate.
e) Provide blow down discharge piping.
4) Steam Boiler with Probe Low Water Cutoff
a) Install low water cutoff probe into tapping “B”. Handle probe with care.
b) Attach low water cutoff control to probe per the instructions packed with the control.
c) Install the gauge glass fittings and ½” extensions into tappings “C”. The lower fitting has a small drain cock.
d) Install gauge glass and protective rods in fittings.
