4.Authorized Service Agent Only: Check the combination gas valve and replace if defective.

B.Main burner flames are small and appear lazy; oil does not come up to temperature quickly.

1.Authorized Service Agent Only: Check gas pressure at the pressure tap of the gas valve. Use dial type or standard water-type U-gauge manometer.
