1. Control knob not fully pressed in

2. Control knob not pressed in long enough

3. Safety interlock system has been triggered

4. Manual shutoff valve not fully open

5. Pilot flame not touching thermocouple,

6. Thermocouple connection loose at con-

trol valve

7. Thermocouple damaged

Maintenance, page 18) or replace ODS/

pilot assembly

6. Hand tighten until snug, then tighten 1/4

turn more

7. Replace thermocouple
