For models starting with CF serial numbers and later. Lockout Conditions

Lockout conditions:

The system will go into lock out mode for the following reasons: Blocked vent pressure switch contacts open:

Check for obstruction in exhaust pipe and vent terminal.

Check for blocked condensate trap or drain line. In cold climates, make sure drain is not frozen. No ignition after 3 attempts:

a)Check inlet and outlet gas pressures (pressure taps located on top of gas valve).

b)Igniter resistance too high (lower resistance preferred < 150 ohms).

c)Misadjusted veturi screw (should be 6.5 turns out from bottom).

d)Flame sense microamp not present (1.0 microamps minimum, should be 5 microamps or more). If burner lit, check flame rod for deposits.

e)Check burner tube condition. Refer to section EF-III for Burner Tube Inspection and Replacement.
