Up to 7 seconds will be allowed for ignition to be detected. The igniter-injector
relay will
be turned off one second after flame is detected.

After 2 seconds of continuous flame,
FLAME PROVEN
will be displayed and the flame
strength will be indicated. After 5 seconds, the current date and time will be displayed in
place of the flame strength.
8.
With the unit firing properly, it will be controlled by the temperature controller circuitry. The
heater’s
VALVE POSITION
will be continuously displayed on the front panel bar-graph.
Once the demand for hot water has been satisfied, the Control Box will turn off the SSOV gas

3.10 START/STOP LEVELS
The ignition position (start) and stop levels are the Air/Fuel Valve positions (% open) that start
and stop the unit, based on load. These levels are Factory preset as follows:
Fuel
Model
Stop Level
Ignition Position
Natural Gas All
16%
25%
Normally, these settings should not require adjustment.
Note that the energy input is not linearly related to the Air/Fuel Valve position. Refer to Table 3-
7 for the relationship between the energy input and Air/Fuel Valve position for a unit running on
natural gas.
