1. The conguration of each unit will vary with specic job requirements such as input rating, electrical specication and special agency approval
codes. The above chart shows those items standard to a basic burner plus a few options that may be added.
2. Indicator lights are “Power On”, “Call for Heat”, ”Fuel On” and ”Flame Fail” for hard wired panels. “Alarm”, “Low Water”, “Power”, “Call for
Heat”, “Ignition On”, and “Fuel On” for circuit board light panels.
?. Larger motors may be required for single phase or 208 volts
The above maximum ratings are based on 0 furnace pressure, an altitude of 1000 feet, 90
o
F air temperature and 60 HZ electrical
supply. Use the following corrections for higher temperatures and altitude. Capacity decreases by 17% for 50 Hertz.
Capacity decreases by 4% for each 1000 feet above 1000 foot altitude.
Capacity decreases by 5% for each 1 inch of furnace pressure.
Capacity decreases by 2% for each 10

F.
Gas input ratings based on 1000 BTU/cu ft. and 0.64 specic gravity. Sizes and pressure will vary with gas.
Essential Ordering Information and Data:
Power Supply - Conrm 120-60-1 for control circuit and electrical supply for burner motor(s) (voltage, frequency and phase).
Describe Boiler or Heater to be Fired - Including the manufacturer, model number, furnace pressure and furnace size.
Firing Rate - Dene ring rates in MBH for gas. Fuel to be Burned - Type of gas, including the BTU value.
Approval Agency - UL, FM, IRI (GE GAP), CSD-1, NFPA, Mil spec and local codes, if applicable.
Flame Safety Control Preferred - Honeywell or Fireye controls.
Gas Train Components Preferred - ASCO/ITT, Honeywell or Landis
Control System - ON-OFF, Low Fire Start, Low-High-Low, Modulation, Posi-Control
Required Options - Mounting plate, limit controls, etc.
Model SC - Specication Data (2,400 MBH - 28,800 MBH Input)
