Hot water should be 180 degrees for use in sanitation. Due to boiler regulations in the Bay Area, R.F. MacDonald Co. was called to upgrade a Cleaver-Brooks Flextube process hot water boiler, which had an older model ProFire Cleaver-Brooks burner. The older burner was upgraded with a top-of-the-line Cleaver-Brooks NTH25 Ultra Low NOx burner (2.5 MBTU) with a Hawk ICS control panel. The RFMCO Service Dept, known for its quality of service, cleaned & painted the boiler after the job was done.  FLX-700-250-160 HW NTH-25 Ultra Low NOx Burner Upgrade LP Gas (Propane) Burner Hawk ICS Panel with PLC Control Upgrade Climate Controlled Vents Inspected & Cleaned Boiler Flue Area Cleaned & Painted Contact Us for your wine application needs!
