* PIPE RELIEF VALVE TO OPEN DRAIN

** 140°F (60°C)TO 150°F (66°C) SHOULD BE MAXIMUM WATER

TEMPERATURE MAINTAINED IN THE PRE-HEATERS.

120°F (49°C) SHOULD BE THE MINIMUM TEMPERATURE OF WATER
IN THE PRE- HEATERS.

CONNECT CIRCULATING LINE FROM FIXTURES, IF USED, TO COLD
WATER SUPPLY LINE OF PRE-HEATER.

CONNECT CIRCULATING LINE OF 180°F (82°C) OR BOOSTED WATER,
IF USED, TO INLET WATER LINE TO BOOSTER.

INSTALL IN ACCORDANCE WITH LOCAL CODES.

TWO TEMPERATURE - TWO HEATERS (ONE PRE-HEATER/ONE BOOSTER HEATER)

WITH OR WITHOUT BUILDING RECIRCULATION

DANGER

TEMPERATURE SETTING SHOULD NOT EXCEED SAFE TEMPERATURE AT
FIXTURES. SEE WATER TEMPERATURE CONTROL WARNING ON PAGE 24.
IF HIGHER PREHEAT TEMPERATURES ARE NECESSARY TO OBTAIN
ADEQUATE BOOSTER OUTPUT, ADD AN ANTI-SCALD VALVE FOR HOT
