1) To measure Gas Pressure, see Measuring Gas Pressure, chapter 4.14, page 31.
2) Activation varies with inlet water temperatures from 0.5 - 1.6 gallon/minute (1.9
- 6.1 l/m).
3) Protection against water drops.
If appliance is installed at elevations above 2000ft, refer
to chapter 4.3.8 Fan speed adjustment.
