Frequency
Component/Item
Recommended Test
Daily
Maintenance
Boiler surroundings
Inspect the area to assure proper clearance to combustible materials,
gasoline, and other flammable vapors and liquids.
Gauges, monitors, and indicators
Make visual inspection and record readings.
Combustion Properties
Check combustion properties as specified in section VII, part D.
Burner flame
Make visual inspection of burner flame as stated in section VII, part D.
Low Draft, fan air pressure, and damper
position interlocks
Test low draft, fan, air pressure, and damper position interlocks
according to instructions if so equipped.
Weekly
Maintenance
Igniter
Make visual inspection, check flame signal strength; log.
Flame signal strength
Read and log flame signal meter, read for both pilot and main flames.
Flame failure detection system
Close manual fuel supply for (1) pilot, (2) main fuel cock, and/or
valve(s); check safety shutdown timing. Refer to section VII, Part D.
Firing rate control
Check firing rate control, place TSBC™ in manual mode and check
high and low firing settings for proper operation.
Pilot and/or main fuel valves
Open limit switch and make aural and visual check; check valve
position indicators and check fuel meters if so fitted.
Low-water fuel cutoff
Test low-water fuel cutoff device and alarm according to
manufacturer’s instructions.
Monthly
Maintenance
Flue, vent, stack, condensate drains,
and outlet dampers
Confirm that components are gas tight and free from obstructions to
flow.
Gas pressure interlocks
Test high and low gas pressure interlocks.
Water condition
Test condition of water, correct condition as needed.
Semi-Annual
Maintenance
Gauges, monitors, and indicators
Recalibrate all indicating and recording gauges.
Flame failure detection system
Check components.
Condensate drain tubes
Check drain tubes have liquid in trap and condensate is properly
directed.
Air filter
Check air filter as specified in section VII, Part D.
Interlocks and valves
Check piping and wiring of all interlocks and shut off valves if so
equipped.
Circulators and system pumps
Maintain according to manufacturers' instructions.
Annual
Maintenance
Flue, vent, stack, or outlet dampers
Confirm that components are gas tight and free from obstructions to
flow.
Combustion Properties
Check combustion properties as specified in section IV, Part I, Step 5.
Flame failure detection system
Conduct pilot turndown test according to manufacturer’s instructions.
This test is required annually and after any adjustments to flame
scanner mount or pilot burner.
Pilot and/or main fuel valves
Check all coils and diaphragms; test other operating parts of all safety
shutoff and control valves.
Pilot and/or main fuel valves
Perform leakage test on pilot and main gas and/or oil fuel valves, in
accordance with instructions.
Flame safeguard
Test purge timing according to manufacturer’s instructions.
Air Filter
Replace.
Boiler trim
Remove lower front jacket panel and check for any signs of corrosion
and leaks.
High limit and operating temp. controls
Test proper operation.
As-Required
Low-water fuel cutoff
Recondition or replace.
Safety relief valves
Test safety relief valves in accordance with ASME Boiler and Pressure
Vessel Code, Sections VI and VII.
