Burner does not achieve

capacity.

• Main gas control valve is not

functioning.

Check actuator and linkage.

• Burner is firing below rated

input.

Check gas pressure differential.

Adjust main gas pressure

regulator as necessary.

• Burner gas holes are plugged.

Inspect gas holes for dirt or lint

as needed.

PROBLEM POSSIBLE CAUSE SOLUTION

• The igniter is not correctly

grounded to the burner.

• Igniter insulator is broken.

Igniter is grounding out.

Not enough gas:

• The gas flow into the burner is

too low.

• Gas valve does not open.

Start-up sequence runs but

burner does not light.

(continued)

Clean the threads on the igniter

and the burner. NOTE: Do not

apply grease to the threads on

the igniter.

Inspect the igniter. Replace if

broken.

Check the start-up settings.

Adjust low fire gas setting if

necessary.

Check the wiring to the

automatic gas shut-off valve.

• Flamerod grounding out

Replace if necessary.

Inspect and clean sensor.

No flame signal:

• Broken flamerod

• Dirty UV scanner lens

Verify that the flamerod is

installed correctly and is the

correct length.

The low fire flame is weak or

unstable.

• Not enough gas

Check start-up settings and

adjust to increase gas flow.

Check air pressure drop across

the burner and adjust.

• Incorrect air flow setting

The burner does not go to

high fire.

• Not enough gas pressure out of

main gas regulator.

Adjust pressure regulator so

pressure is provided as stated

in Data 135.

Check for clogging of valves and

regulators in gas line. Pressure

regulator may be incorrectly

sized. Replace if necessary.

• Gas pressure drops as input is

increased.

• Main gas control valve is not

functioning.

Check actuator and linkage.
