Follow these start-up instruction steps for initial start-up
before building repopulation. For normal start-up, simply
adjust the thermostat on the building’s environment
controller above room temperature.
1. Open all gas supply valves to the heater(s) and
check for gas leaks at all connections using
approved lead detectors.
2. Energize the solenoid of the zone control panel to
allow full 5 PSIG flow to the heater.
3. Fully depress the pilot button on the pilot safety
control valve while applying flame to the main
burner cone point. On initial start-up leave the
main burner on for several minutes to bleed
residual air from the system.
4. De-energize the solenoid of the zone control panel.
The pilot flame should light and remain lit upon
completion of transition from full output to pilot.
Note: It is normal to have flame “pop” out of the
air inlet of the heater when cycling from
main burner mode to pilot mode.
5. Set the thermostat controlling the heater(s) to the
desired temperature.
