Gauge Glass - Not required on hot water boilers only.
The water gauge glass must be kept clean. Dirt on, or in, the glass may be mistaken for the water
level. Do not allow steam or water to leak from the water glass, as this may effect the accuracy of
the level indication. Leaking of the gauge glass will also reduce the wall thickness of the glass to the
point where it may explode.
WARNING: DO NOT OPERATE THE BOILER WITHOUT THE GAUGE GLASS PROTECTOR
INSTALLED. NEVER ATTEMPT TO WORK ON THE GAUGE GLASS WHILE THE
BOILER IS UNDER PRESSURE. ALWAYS CLOSE GAUGE VALVES PRIOR TO
TIGHTENING GASKETS ON WATER LEVEL GAUGE GLASS. SERIOUS INJURY
COULD RESULT.
