Follow the start-up instruction steps for pilot light heaters for
initial start-up before building repopulation. For normal
star t-up, simply turn the thermostat 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. 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:
For the pilot heater 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.
