* 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 total 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.
