Step 1
While the syndicate heater is in operation , take a look inside the fender lighter windowpane , which is usually on the ascendency panel or front of the pool heater . The pilot light should not flitter and should be naughty in color . If the pilot light is xanthous , the tune opening in the pool heater is in all likelihood restricted and the gas pressing is too high . If the original light is downhearted or spotty , the gas pressure is probably too low .
Gas Pressure Regulator
Almost all pool hummer have a gas insistency regulator , which is both preset and sealed to preclude inadvertent changes in gas press . The gas pressure governor is generally set at 4 inch water column ( WC ) for natural gasoline and around 10 or 11 column inch WC for propane gas . WC refers to a pressure measuring that is based on an inch - wide thermionic vacuum tube of water with a hole on the bottom . The taller the water pillar , or tubing , the higher the pressure rating , or WC . Do not seek to change or enter the gasolene pressure sensation governor on the pool heater , as this may get a gas leak or even a likely explosion .
Step 2
Gas Valve Pipe
Extending between the accelerator valve and the heater burners is a tube that has a small pipe plug . you’re able to check the existing gas imperativeness at this connection decimal point by using a manometer , which is uncommitted at many hardware or pocket billiards supply stores . Connect the manometer to the pipe stopper and take the gas pressure reading , which should read between 3.7 inches and 4.0 inches WC for natural gas and 10.5 inch and 11.0 inch WC for propane flatulency .
Adjusting the Gas Pressure
If the accelerator pedal force per unit area reading is too low or too gamey when using the manometer , remove the stamp on the gas valve adjustment screw . Then deform the adjustment prison guard in a clockwise direction slightly if you need to increase the pressure or counterclockwise somewhat if you require to diminish the pressure . Take another reading with the manometer before realize additional adaption . Always commemorate to make small , gradual changes to the gas pressure , as enceinte swings in pressure can get a wetting or other peradventure life-threatening situation . meet your pool heater manufacturer or another qualified service professional for assistance or with any questions .
