Pipe Insulationo Available for missing/defective Insulation (not for
new pipes)o Incentives vary by pipe size and R factoro Documentation (pictures) of existing Insulation
and new Insulation are required
Application must be submitted by the facility/boiler ownerContractor information/sign-off required (final application)Pre-Approval Application required only if:◦
Total incentive request will exceed $10,000 (and/or) ◦
Total estimated # of failed steam traps exceeds 30 (and/or)◦
Total estimated installed pipe insulation exceeds 300 linear feet◦
Customer wants to confirm eligibility and reserve incentive funds prior to completion of work
Final Approval Application always required◦
DCEO will review, approve and issue the check

Appendix B –
Section 3 –
“Technician Pipe Insulation Reporting Requirements”
Must be filled out in its entirety ◦
Section 1: General Information
◦
Section 2: Building/Facility Information
◦
Section 3: Applicant Certifications
Section 1: “Contractor Boiler Tune-Up Reporting Requirements”
Section 2: “Technician Steam Traps Reporting Requirements”
Section 3: “Technician Pipe Insulation Reporting Requirements”
Must be completed by the Contractor performing the work
Complete a separate Section 1 for each boiler included in the application
A copy of the Contractor’s standard Combustion Report must be attached to the filled out worksheet.
Tune-Ups must produce energy savings to be eligible (e.g. after tune-up readings must have higher efficiencies than before tune-up readings)
Checklist of tasks to be completed
The contractor performing the tune-up is required to initial that each of the following tasks has been completed.
Measure combustion efficiency before tune-up using an electronic flue gas analyzer
Include copy of combustion analyzer test (combustion report)Adjust airflow and reduce excessive stack temperaturesAdjust burner gas input, manual or motorized draft controlClean burners, combustion chamber and fire-side exchange
surfaceInspect and clean burner nozzlesCheck for proper ventingComplete visual inspection of system piping and insulationCheck safety controlsCheck adequacy of combustion air intakeMeasure combustion efficiency after tune-up using an
electronic flue gas analyzer
Identify method of failure detection:◦
Pyrometer (Infrared Thermometer)◦
Listening Device (Ultrasounds)◦
Visual Inspection
Provide Steam Trap Information◦
ID Tag Number◦
Trap Location◦
Trap Type◦
Technician Initials –
verifies failed trap (open position)
