CONNECT CIRCULATING LINE FROM FIXTURES, IF
USED, TO COLD WATER SUPPLY LINE OF PRE-
HEATER.
CONNECT CIRCULATING LINE OF 180°F OR BOOSTED
WATER, IF USED, TO INLET WATER LINE TO BOOSTER.
INSTALL IN ACCORDANCE WITH LOCAL CODES.
DANGER
TEMPERATURE SETTING SHOULD NOT EXCEED SAFE TEMPERATURE AT
FIXTURES. SEE WATER TEMPERATURE CONTROL WARNING ON PAGE 23. IF
