UNIT SELECTION Selection Procedure In order to properly select a unit heater it is necessary to have the following basic information. 1. Heating output capacity Model size output is to be matched against the heat loss to be replaced. 2. External static pressure (blower units only) The external static pressure (E.S.P.) is determined using the ASHRAE Guide for duct losses or provided by the design engineer. 3. Accessory internal static pressure (Nozzles, transitions, filters, etc.
UNIT SELECTION Selection Example Conditions (Blower Unit) In the following example, select a unit heater to meet the following conditions: 1. Heating output capacity = 156,000 Btu/Hr per design engineer 2. External Static Pressure = 0.2. 3. Internal Static Pressure = 0.0. No static producing accessories are required 4. Heat exchanger and burner = Aluminized Steel 5. Gas Type = Propane 6. Gas Controls = Two stage Intermittent Pilot 7. Supply Voltage: 230V/60Hz/3Ph 8. Altitude: 1,000 feet 9.
