3.10 START/STOP LEVELS
The 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:
Start Level Stop Level
RECON 500 28% 16%
RECON 1000 25% 20%
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.
