ABSN partnered with Bethel Community Services Association, YKHC’s Yuut Elitnaurviat Learning Center and AVCP Housing Authority to provide ABSN’s 16 hour boiler training course to 7 rural maintenance staff. Charlie deer’s training hours were covered by $2,100 in matching funds from ABSN. AEA VEUEEM grant funds were used to cover air fair and lodging in Bethel for the following maintenance staff from this grant’s villages: Chefornak: Bernard Mael, Kongiganak: John Phillip, Kwigillingok: Benedict White, Mekoryuk: Alvin David, Quinhagak: Norman Cleveland and Adolph Pleasant. Andrew Lind of Port Heiden (NW-SW Region VEUEEM grant) was also brought to Bethel for this class. Components of a Bacharach Flu Gas Analyzing Kit used in boiler efficiency training and left with capable maint staff in their villages. Smoke -test kit for analyzing flu gases for boiler efficiency Schematic of outdoor temperature sensing boiler control During this 16-hour course ABSN’s boiler specialist Charlie Deer instructed maintenance staff in the fundamentals of boiler and fuel energy efficiency. Training topics covered: fuel, proper heating system sizing, testing boiler efficiency with a flu gas analyzer kit, cleaning and tuning boilers for energy efficiency, control options and proper control function, burner and nozzle components and function, outdoor temperature boiler controls, programmable thermostats, etc.
