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