Assessment | Existing boiler, burner, gas valve, and gas pressure booster will be capable for modulation Compatibility between specified controls and existing burner will be confirmed Remaining existing controls will be confirmed as installed correctly Current settings will be documented | Document the status of existing controls |
| 5.3102.27b
Repair | Existing installation will be corrected if settings do not match specified scope of work Appropriate repairs will be made to the following components in accordance with scope of work and manufacturer specifications: - Linkage
- Gas/oil valves
- Air damper on burner
- Combustion controls
| Ensure boiler modulates to optimize efficiency Reduce short cycling |
| 5.3102.27c
Replacement of modulation control | Existing controls will be removed All new pressure controls will be free of mercury New controls will be installed in accordance with manufacturer specifications New control will be set to temperature settings (hot water boiler) and pressure settings (steam boiler) as stated on scope of work Applicable burner linkages, nozzles, cams, oil pump pressure setting, and gas valve will be adjusted to specified burner firing range | Ensure boiler modulates to optimize efficiency Reduce short cycling |
