– Release Heating Control Signal Override
• Low Fire Test Following Normal Burner Starting
Sequence
– Override Heating Control Signal to 0 percent
– Confirm PG1 and PG2 pressures are within
±5 percent of the pressures shown on Burner Data
Plate
– Allow a minimum of 5 minutes of operation at
0 percent heating signal
– At ROD read and record
• Outdoor Air Temperature

warm-up period
WARNING
Hazard of Explosion!
Failed gas components could explode or leak
flammable gas which could cause a fire resulting in
death or serious injury or property damage. To avoid
damage to unit if PG1 or PG2 exceed data plate
pressures +5 percent, disable incoming gas using the
manual shutoff valves and ensure incoming pressure is
within nameplate data BEFORE enabling the gas.
