* INPUT & OUTPUT ADJUSTMENT:
- Pump pressure can be adjusted to maintain proper firing rate.
- Increase pump pressure if flue gases temperature is under 400°F
- Adjust the tota._l flue gas temperature between 400 ° and 575°F (330 ° and 505 ° F net approx.)
- Adjust fan speed for air temperature rise of 55 ° to 85°F.
** AFUE value established after minimum 20 hours of operation.
