3. Inspect heating system for other problems.

necessary.
5. Inspect premix flexible couplings for damage or
excessive wear.
6. Check for leaks in gas train, blower, and blower-
to-burner piping.
Recommended Annual Maintenance
The following steps should be carried out annually:
1. Have combustion (CO2, O2, CO) and input
checked by qualified personnel.
2. Clean dirty flues to prevent air flow restrictions
resulting in poor combustion and loss of
efficiency.
3. Flush boiler if necessary. See
Boil Out Procedure
section of this manual. More extensive cleaning
may be required; consult a local water chemistry
expert for recommendations.
4. Provide annual inspection by a qualified ASME
boiler inspector, as required by local codes.
After All Repairs or Maintenance
1. Follow “Pre-Start Check List” and all Safety
Checks.
2. Operate the boiler and perform combustion
safety checks.
3. Analyze combustion throughout the range and
verify proper operation of safety devices.
