Air pressure switch circuit is opening

1.

Ensure air pressure switch hose is not kinked or clogged;

2.

Check vent temperature limit switch - if it is determined

 

 

 

temperature limit switch (these two switches

 

 

 

are wired together in a “series” circuit).

 

that the vent temperature limit switch is opening its

cycle - replace the vent temperature limit switch.

 

 

 

 

3.

Ensure water heater is not over-firing. 3.1 Check burner

 

 

 

 

 

orifice size and ensure the correct orifice is installed;

 

 

 

 

 

replace as necessary. 3.2 Check manifold gas pressure

 

 

 

 

 

and ensure it is within 0.3” W.C. (75 Pa) of listed rating on

 

 

 

 

 

Intelli-Vent™ control valve. Manifold gas pressure is

 

 

 

 

 

non-adjustable, if manifold gas pressure is off by more

 

 

 

 

 

than 0.3” W.C. (75 Pa), replace the Intelli-Vent™ control.

 

 

 

 

4.

Ensure condensate lines are not obstructed. Check and

 

 

 

 

 

clear all condensate lines including the floor condensate

 

 

 

 

 

drain line.
