WATER ON BASE 1. A cold environment and/or intermittent firing may allow inner casing to heat up
above the condensation temperature of the flue gasses.
A. Increase temperature of the cold boiler room if possible.
B. Verify insulation is in place between inner and outer casing and replace if
missing.
C. Reset controls for less cycling to allow boiler to run for longer periods of time
to heat inner casing above condensation temperature.
2. Cold system startup.
A. Any time a boiler is started with a cold system, it will produce condensate
until internal surface temperatures exceed 130
°
F. Internal condensation will
not be produced once a boiler has warmed up. Condensate will dry up after
a short time. Limit number of cold starts.
3. Cold return temperatures.
A. Return temperatures below 120
°
F. will continually produce condensation.
Raise return temperatures above 120
°
F.
4. Gasket leaks allow gases to escape and condence on relatively cool base.
A. Gasket may need to be replaced or inner casing not installer per instructions.
Install inner casing and gasket per instructions outlined in Chapter 8,
SectionD.
