Table 3
¹ These fl ow are based upon setting the unit to higher temperatures and then mixing down using cold water after
the unit, to reach these fl ow rates.
²
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.
³ When converted to LPG the minimum input is 17 000 BTU/hr (5 kW).
⁴ With constant fl ow.
⁵ Can be reprogrammed to achieve up to 140 °F (60 °C).
⁶ Requirements: Steady fl ows, single unit installations, up to 140 °F (60 °C).
⁷ To measure Gas Pressure, see installation manual - Measuring Gas Pressure, chapter 4.13, page 36.
⁸ Refers to activation point. Deactivation point value is 0.35GPM (1.3 l/min).
Protection against water drops.
