SYMPTOM

POSSIBLE CAUSE

CORRECTIVE ACTION

Dark spots on 

ceramic surface

1. Foreign matter behind the ceramic surface 1. See Maintenance, Paragraph 11.1.

2. Foreign matter inside burner assembly

2. Replace burner assembly.

Low ceramic sur-

face temperature

1. Venturi obstructed (by spider web)

1. Clean with a bottle brush.

2. Foreign matter in venturi

2. See Maintenance, Paragraph 11.1.

3. Orifice partially blocked

3. See Maintenance, Paragraph 11.1.

4. Supply gas pressure low

4. Adjust supply regulator to 7” w.c. (18cm w.c.) for natural 

gas, or 11” w.c. (28cm w.c.) for propane.

5. Manifold gas pressure low

5. Adjust heater regulator to 6” w.c. (15cm w.c.) for natural 

gas, or 10” w.c. (25cm w.c.) for propane.

6. Manifold misaligned from excessive torque 

applied on pipe at installation

6. Replace manifold.

7. Flue gases not adequately ventilated

7. See Ventilation Requirements, Paragraph 2.2.

8. Gas supply piping too small

8. Increase supply pressure or replace piping

2-Stage transition 

from low-heat to 

high-heat does not 

happen

1. Ambient temperature is still in low-heat zone 

of thermostat

1. Check thermostat manufacturers’ instructions.

2. Thermostat defective

2. Replace thermostat.

3. High-heat valve not opening

3. Replace high-heat valve.

2-Stage transition 

from high-heat to 

low-heat does not 

happen

1. Ambient temperature has not reached low-

heat zone of thermostat

1. Allow time for ambient temperature to reach low-heat zone 

of thermostat. Check thermostat manufacturer's instructions.

2. Thermostat defective

2. Replace thermostat.

3. High-heat valve not closing

3. Replace high-heat valve.
