1.
Apply Teflon tape or pipe dope to pipe threads. Install top gauge
fitting (fitting without a drain valve) into the uppermost tap-
ping.Wrench tighten the fitting until it is snug and the glass outlet
is pointing at five o'clock (about 1/8 turn from its final downward
vertical position).
2.
Install the bottom gauge fitting (the fitting with a drain valve)
until it is snug and the glass outlet is pointing directly
upward.Verify top and bottom fittings are threaded into the tap-
pings the same number of turns (distance A= distance B).
3.
Remove glass packing nut, friction washer (or packing gland,
depending upon the model), and glass packing from the fittings,
and place them, in the same order, on to both ends of the gauge
glass. Push both packings about an inch up the gauge glass.
4.
Gently insert one end of the glass into the top gauge fitting.
Keeping the glass inside the top fitting, gently rotate the top
gauge fitting clockwise until vertically aligned with the bottom
gauge, then insert glass into bottom fitting until glass bottoms out
on the shoulder inside the bottom fitting.
5.
Carefully raise glass about 1/16" and slide lower glass packing
down until the glass packing contacts the lower gauge fitting.
DO NOT allow the glass to remain in contact with any metal!
6.
Carefully slide upper glass packing up as far as possible.
7.
Hand tighten both glass packing nuts, then tighten 1/2 turn more
by wrench.Tighten only enough to prevent leakage. DO NOT OVER
TIGHTEN! If any leakage should occur, tighten lightly, a quarter
turn at a time, checking for leakage after each turn.
