Harsco Industrial C1500H Installation & Owner's Manual page 48

Correct air adjustment is essential to the efficient operation of this boiler. Ensure that the flow of combustion and
ventilation air is not obstructed. If an adjustment in the combustion appears necessary, the flue gas composition
should be checked with a carbon dioxide (CO
3-1 of section 3.11.2.1. If an adjustment in the combustion is necessary, call a qualified and knowledgeable installer or
service agency that has been trained on the Harsco Industrial, Patterson-Kelley MACH
5.1.3 Monthly
1. Using the control panel, enter the information mode and scroll down view the flame signal. This is measured in
micro-amps of flame conductivity.
2. Test high-limit Control. Refer to Section 3.9.3.
3. Test operating temperature controls by reducing or increasing temperature setting as necessary to check burner
operation.
4. Test the low water level cut-out. Refer to Section 3.9.2.
5. Test low gas pressure switch. Refer to Section 3.9.4.
6. Check the condensate drain system. Clean and flush as necessary.
Installation and service must be performed by a qualified and knowledgeable installer or service agency that has been
trained on the Harsco Industrial, Patterson-Kelley MACH
5.1.4 Semi-Annually (required for boilers operated year round)
In addition to the recommended monthly service:
1. Clean burner of any accumulated dust or lint. See Section 5.2 on "Cleaning the Burner."
2. Inspect burner for any signs of deterioration or corrosion. Replace immediately if deterioration or corrosion is
evident.
3. Check the pH level of the system fluid.
4. Inspect and clean the condensate system and check for leaks. If a condensate neutralization kit is present, open
the lid and inspect the limestone rocks. If they are absent or have been significantly worn away, replace them
with new limestone rocks. Use hi-calcium (or pure) limestone.
Note: replacement media (rocks) can be ordered through you local HIP-K Representative.
Installation and service must be performed by a qualified installer or service agency that has been trained on the

The blower motor is permanently lubricated and does not require periodic lubrication.
5.1.5 Annually
In addition to the recommended monthly and semi-annual service:
1. Inspect and clean the inlet screen of any accumulated dust or lint.
2. Check burner and clean off any soot or foreign material that may have accumulated. See Section 5.2 on
"Cleaning the Burner." Check for corrosion of the burner and its parts. If there is evidence of deterioration or
corrosion, replace immediately. Inspect combustion chamber when the burner is removed for inspection. Note
any signs of deterioration. Clean as necessary.
3. Inspect and clean heat exchanger. Remove the various covers to inspect the flue gas passageways. Clean the
combustion side casting pins by flushing with clean water. Do not use any cleaning agents or solvents. Do not
use soap. Be sure to inspect the condensate collection pan that is the lowest part of the heat exchanger. Then
empty out the condensate trap of any debris.
4. Replace the igniter, flame rod and gaskets as applicable
