THE FOLLOWING STEPS AND DIAGRAM INDICATE THE LOCATION OF THE CONNECTION
POINTS REQUIRED TO MEASURE THE MANIFOLD PRESSURE.
THE MANIFOLD PRESSURE MAY BE MEASURED USING A U-TUBE MANOMTERE OR A
DIFFERENTILA PRESSURE GAUGE. THE DIAGRAM SHOWS THE CONNECTION OF BOTH
MEASURING DEVICES BUT ONLY ONE DEVICE IS REQUIRED TO MEASURE THE MANIFOLD
PRESSURE.
© REMOVE THE PLUG. INSTALL APPROPRIATE BARBED FITTING AND CONECT THE PRESSURE
SIDE LINE FROM THE U-TUBE MANOMETER OR THE DIFFERENTIAL PRESSURE GAUGE.
REFER TO CHECK OUT PROCEDURE AND ADJUSTMENTS IN THIS MANUAL WHEN READING
MANIFOLD PRESSURE.
WHEN MEASUREMENT IS COMPLETE, DISCONNECT U-TUBE MANOMETER OR DIFFERENTIAL
PRESSURE GAUGE. BE SURE TO REINSTALL 1/8" PLUG, USING APPROPRIATE PIPE THREAD
SEALANT APPROVED FOR USE WITH NATURAL AND LIQUIFIED PETROLEUM GASES.
