Remedy
Check traps, clean or replace as required.
Call water treatment company and consult
the factory.
Dump the return tank and flush the system.
Test the water treatment.
Check total equipment load against the boiler
output. Decrease amount of equipment being
used.
Check draft is neutral. Consider installing a
barometric damper if the draft is too strong.
Adjust main air.
Check tank and lines for water or leaks.
Check traps. Clean or replace as required.
Dump the return tank and flush the system.
Test the water treatment.
Clean or replace as required.
Check relay is secure on its base, if so
replace the relay.
Check for tightness and clean.
Allow system to cool down, check steam traps
and check to be sure return lines are not
insulated. Check return tank temperature, if it is
above 82 C vapour locking of the pump will
O
occur. Inspect check valves. Clean and replace
as needed. Replace pump with multi-stage
centrifugal pump able to cope with 121
Check feed water line is not blocked, clean as
required.
Check probes, clean as required.
Check to ensure the contactor is live.
Check to ensure the contactor coil is being
pulled in. Replace as required.
Check the pump circuit is live. If the circuit is live
but the pump is not running, replace the pump.
Check the valve is opening and closing.
Clean or replace as required.
Check the draft with a gauge, should read neutral.
May need to install a barometric damper.
Ensure the boiler room doors are closed and the
recommended vents are clear.
Dirty probes, clean or replace as required.
Check relay is secure on its base, if so
replace the relay.
Check for tightness and clean.
As the boiler cools it pulls water from the system.
To prevent this, add an anti-vacuum valve on the
steam gauge assembly piping, this valve closes
under pressure and opens under vacuum.
