Gauge Glass - Replacement (Electric Steam Boilers Only)
1. Follow Steps 1 through 4 of the shutdown procedure (page 19) to take the unit
off-line before attempting to replace the gauge glass assembly.
t The combination of electricity and water can pose a very dangerous situation.
Assure that all power has been shut off / disconnected and locked out in an
approved manner, before attempting any installation or maintenance procedures.
2. After assuring that the power has been turned off and locked out, the pressure bled
from the tank, the water drained, and the unit has had time to cool, break the joints
that secure the gauge glass assembly to the tank.
Note: While designed for heavy duty service, the glass in the assembly is fragile. The
assembly should be treated gently to avoid breakage of the glass.
3. Carefully continue to unscrew the fittings from the tank until the gauge glass
assembly is free.
4. Install the new gauge glass assembly by screwing the fittings into the tank. Follow
recommendations contained in the manufacturer's documentation, local codes, or
accepted contractor practices as to the use and / or type of joint compound or
sealer at the connections.
6. Follow the startup procedures (page 17) to put the unit back on-line. Carefully
check all connections for any sign of leakage.
High Pressure Cut Off Switches - Replacement
(Electric Steam Boilers Only)
Each CEMLINE Electric Steam Boiler is equipped with two (2) types of high pressure cut
off switches:
n automatic reset; and
n manual reset.
While each high pressure cut off switch serves a different function within the system, the
procedures to replace them are similar.
Both high pressure cut off switches are located on the top of the boiler. While the high
pressure cut off switches are relatively similar in physical appearance, the manual reset
model is recognizable by the reset button.
