Gas Input Rate Figure 14: Input Graph The gas input rate of this water heater is affected by several environmental factors such as: • The heating value of the gas • The air and gas densities (which vary widely due to baro- metric pressure and temperature changes) • Venting installations (pipe diameter, length and fittings) • Altitude When measuring the input rate these factors should be incorporated into the calculations. Also measure the gas consumption over a sufficiently long time to obtai
