   A knockout drum should be provided on the fuel gas supply to each

   heater (or group of heaters when located close to each other) to keep

   condensate out of the heaters. A slug of fuel gas condensate entering a

    gas-fired heater can extinguish the flame and flood the floor of the

   firebox and upon reignition cause serious fire damage of the heater

   and/or adjacent equipment.
