Warning:
Before each heating season begins, have the following
service and maintenance done by a professional service
technician:
1) Boiler heat exchanger inspected and cleaned.
2) Vent system inspected for deterioration, leaks,
corrosion, proper draft, and proper operation. Check
vent system for compliance with local and national
code requirements. Repair or replace as required.

into living space which could cause carbon monoxide
poisoning.

to boiler before performing any service or maintenance
on the boiler, burner, or control. Failure to follow this
warning could result in electrical shock, serious
