2. Test operating temperature control by reducing temperature setting as
necessary to check burner operation.
3. Check flue gas temperature at outlet. If there is a temperature increase over
previous readings, the probable cause is soot or water-scale build-up on the
tubes. Consult Fulton Heating Solutions immediately if there is a concern.
4. Test low gas pressure switch and high gas pressure switch utilizing the
procedure in Operation section of this manual.
5. Inspect the combustion air inlet filter. If dust, lint or debris has accumulated,
replace the filter.

Procedure for Inspecting the Air Inlet Filter

Proceed as follows:
1. Remove the filter. The filter sits in the slot above the cabinet.
2. If debris has plugged or contaminated the filter, the filter must be replaced.
– NOTEE: Operating the burner with the combustion air filter removed will void the
burner warranty. A clean filter of the same Fulton part number (type, size and
style) must be installed while the boiler is in operation.
3. Return the filter to its original position in the slot.

Annual Maintenance Schedule

Annual maintenance must be performed prior to each heating season, and
includes but is not limited to the following tasks, which must be done by a
factory trained technician:
1. Inspect the fuel train, burner and control panel to be sure components are
free of debris and are properly attached to the boiler.
2. Replace the combustion air filter with a new filter of the same Fulton part
number (type, size and style).
3. Examine the venting system (air intake and exhaust piping).
Check all joints and pipe connections for tightness.
