PUMP PRESSURE ADJUSTMENT
While heater is operating, turn relief valve clockwise to increase,
counterclockwise to decrease. Use flat blade screwdriver to turn valve.
Correct pump pressure is as follows: 6.0 PSI (tolerance ± 10%).
For best measurement of pressure, test with full tank of fuel. Optimum
pressure occurs when the nose cone is cherry red and there are no
extending flames from the heater.
