ADJUSTING THE GAS PRESSURE

NOTE: If cover plate is already installed, remove it by removing the two screws with a Phillips screw driver.

NOTE: The maximum manifold pressure is set at the factory at 3.5” WC for natural gas and 10.5” WC for propane. To adjust the maximum manifold pressure for altitude, you must remove the manifold pressure adjustment cover. The variable gas control knob must then be removed using a special screwdriver. Rotate and reinstall the knob so that the maximum pressure reading is correct.

Locate the two pressure test taps. Check line pressure or manifold pressure by loosening the small screw inside the tap with a flat-head screwdriver about one turn. Connect pressure gauge using a ¼” I. D. rubber hose.

Ensure the line pressure falls within the allowable limits and adjust the manifold pressure according to the elevation table.

The pilot should have a strong blue flame which engulfs the thermopile and the thermocouple. If there is any yellow in the pilot flame tips, the gas flow must be reduced by adjusting the pilot pressure adjustment screw.
