The effect of static pressure and filter resistance is included in air volumes shown. 1st stage COOL is approximately 70% of the same 2nd stage COOL speed position. Continuous Fan Only speed is approximately 38% of the same 2nd stage COOL speed position.
Lennox Harmony zone control applications − Minimum blower speed is 600 cfm. Max cfm is the same as 2nd stage cool position.
Initial Air Purging
After all plumbing connections have been made, leak tested and flushed, the water heating device is ready to be filled with water and purged of air. Air bleeder valves are provided as a convenience for installations that are not equipped with purge manifolds.
1.Make sure electrical power and gas supply to system are OFF.
2.Remove CBWMV coil section access panel.
3.Remove cap from highest air bleed valve and depress valve stem until water is released. This may be done with a refrigerant style hose. See figure 15.
4.Replace cap on valve and access panel.
5.Apply electrical power and gas supply to the system.
6.Follow the System Start−Up section to operate the sys- tem. Complete purging of air after unit has gone through initial start−up.
