The other hole (on the right) has a screw with a hole which adjusts a ball and spring relief valve assembly. Carefully adjust the screw until the gauge is reading the pressure level that is specified on the heater's label.If operating properly, the pump should produce more pressure than is required to operate the heater.The relief valve allows the excess air to escape before being sent to the nozzle.

The hole on the left has a square or slotted plug inserted.Remove the plug. Screw in the nipple end of the gauge into the threaded hole. Be careful not to cross thread the gauge into the threaded hole. Check for air leaks with soapy water.

The FIRST STEP in diagnosing any heater problem should be checking the output of the air pump. Best Gauge Available.Large 2-1/2"Dial High Quality Gauge and Very Accurate+/-3-2-3%,Proper pressure is essential for efficient heater performance.
