Low NOx Notes:
- The NOx burner assembly is factory set for optimum performance and should only be adjusted or modified by a qualified technician.
- The burner box and premix/blower valve are mated parts - if either part needs replacing the complete assembly will need to be replaced.
- The low-temperature cutoff switch is intended to prevent gas heat operation below 32°F due to low operating temperature limitations with the premix blower component.
- The NOx gas furnace option is not available for high-altitude installations above 2000 ft.
- Manifold pressure is not applicable for units with the Low NOx Gas furnace option. Manifold pressure is not utilized as an adjustment/checking parameter for this system.
