Be certain that the water heater is full of water, that air is purged from all lines,
there are no leaks (gas and water), and all inlet water lines are open.
The following test equipment should be on hand (all test equipment must be
acclimated to ambient temperature before calibration and use.)
– Two U-tube manometers or calibrated pressure gages that can read
0-10" (0-2.5Kpa) and 0-35" (0-8.7Kpa) W.C. pressure gauges.
• Attach a gas pressure gauge or manometer to the upstream side of
main gas cock and a gas pressure gauge or manometer to the manifold
pressure tap (see Figure 15).
