Adjustment
Symptoms of incorrect gas pressure include:
Insufficient gas pressure:
• Small pilot flame which can result in poor pilot
rectification and/or frequent burner outages.
• Little variation in flame picture between HI and
LO regulator settings.
• Insufficient gas to support more than one
appliance causing nuisance outages or gas
surges.
Excessive gas pressure:
• Permanent damage to valve causing complete
appliance shut down.
• Too large a pilot flame resulting in overheating
of the flame sensor and consequent shut down.
• Sooting due to impingement and/or incorrect
fuel to air mix.
WARNING
DO NOT ALLOW THE INLET GAS PRESSURE TO
EXCEED 14.0" WC (OR 1/2 PSIG) AS SERIOUS
DAMAGE TO THE VALVE MAY RESULT.
