BOILER COMBUSTION UPGRADES Requirements: • Boiler must be natural gas-fired, forced-draft boiler used for space heating that operates a minimum of 4,000 hours per year. • Installation on redundant or backup boilers does not qualify for an incentive. • Boiler input capacity must be entered in boiler horsepower (BHP). To convert, use 1 BHP = 33.476 MBh. High turndown burner must be able to provide efficient combustion at a 10:1 turndown ratio or greater. The turndown ratio must be clearly shown on a manufacturer’s spec sheet or similar documentation. • High turndown burner incentives (H2203 and H5237) are eligible on boilers ≤ 1,000 BHP. Boilers > 1,000 BHP may be eligible for custom incentives. • Invoices must be attached and include the manufacturer name and model number of linkageless controls, O 2 trim, and high turndown burner equipment.
