INTELLI-VENT TROUBLESHOOTING GUIDE

FLUE BAFFLE & FLUE RESTRICTOR CHECK

If the flue restrictor is dislodged as shown in the left illustration above, the velocity of air flowing through the combustion

chamber will increase. This can cause air turbulence inside the combustion chamber that leads to:

1 Fuel gas being swept away from the ignitor leading to ignition failure (failure to ignite). The Intelli-Vent control

would lockout after 3 failed attempts and display error code 6.

2 Ignition occurs but the air turbulence blows the flame away from the flame sensor causing burner short cycling. The

Intelli-Vent control would lockout after 3 failed attempts and display error code 6.

A dislodged flue restrictor or baffle can also allow too much heat to flow into the combustion blower and vent system

leading to:

1 Vent temperature limit switch contacts opening during the heating cycle, preventing the thermostat from?

satisfying. The Intelli-Vent control closes the gas valve immediately if this switch activates.

2 Heat damage to the combustion blower and/or vent system components.

The outer and inner combustion chamber access covers and the fiberglass insulation between the outer jacket and the

combustion chamber must also be installed correctly. If not installed properly this could also cause excessive air

turbulence inside the combustion chamber. Insure these covers are installed correctly and the fiber glass insulation is

not removed or tucked/pushed away from these openings when servicing.

Insure the flue baffle, flue restrictor, combustion chamber access covers, and fiber glass insulation between the outer

jacket and combustion chamber are all installed properly to minimize ignition and flame failure conditions.

Flue baffle assembly shown to the left. Insure this is

assembled and installed properly. This can become

dislodged during transport.

Always check the flue baffle assembly if the water

heater has been laid on its side during transport.

Some power vent residential models are equipped with

flue restrictors in addition to the flue baffles installed on all

models. The flue restrictor and flue baffle are engineered

to precisely regulate the flow of flue gases through the flue

pipe. This maximizes the amount of heat conducted into

the water through the walls of the flue pipe. The flue

restrictor and baffle will also affect the velocity of air being

drawn into and through the combustion chamber.
