2.2.7) Vent temperature test
1.
Place a thermometer in the test hole located in the breech pipe.
2. The vent temperature should be between 204°C to 302°C
(400°F to 575°F). If not, check for improper air temperature
rise, pump pressure, nozzle size, or for a badly sooted heat
exchanger.
2.2.8) Fan Limit adjustment and blower regulator
Modification of the “FAN ON” and “HI” Limit settings on the Fan Limit
and blower regulator can cause a malfunction of the furnace and carry
to premature wear of the heat exchanger.
CAUTION
Modification of the factory set limits will void the
warranty.
