 These flow are based upon setting the unit to higher temperatures and then mixing
down using cold water after the unit, to reach these flow rates.
 Input rating is based on sea level operation and need not be changed for operation
up to 2000 ft (610 m) elevation. For operation at elevations above 2000 ft (610 m),
input rating is automatically reduced at the rate of 4 percent for each 1000 ft (305 m)
above sea level.
 When converted to LPG the minimum input is 17000 BTU/hr (5 kW).
 With constant flow.
 Can be programmed to achieve up to 140 °F (60 °C).
 Requirements: Steady flows, single unit installations, up to 140 °F (60 °C).
 To measure Gas Pressure, see installation manual - Measuring Gas Pressure, chapter
4.13, page 36.
 Refers to activation point. Deactivation point value is 0.35GPM (1.3 l/min).
 Protection against water drops.
