14.1 Seasonal Startup
• Before seasonal start-up, have a certified service agency
check boiler for soot and scale in flues, clean burners
and check gas input rate to maintain high operating
efficiency.
• Verify proper operation after servicing.
• Service agency will verify system is filled with water to
minimum pressure and open air vents, if used, to expel
any air accumulated in the system. Check entire piping
system and, if any leaks appear, have them repaired.
• Circulators need to be checked and maintained. Refer to
circulator manufacturer's instructions.
• Inspect venting system at the start of each heating
season.
◊ Check vent pipe from boiler to chimney for signs
of deterioration by rust or sagging joints. Repair if
necessary.
◊ Remove vent pipe at base of chimney or flue and
using a mirror, check vent for obstruction and verify
vent is in good working order.
• Boiler flue gas passageways may be inspected by a light
and mirror.
◊ Remove burner door.
◊ Place trouble lamp in flue collector through draft relief
opening or flue inspection cover.

With paper still in place in base, clean top of boiler
castings of boiler putty or silicone used to seal between
castings and flue collector. Verify chips are not lodged
