2. Specifications
Note 1: The default factory setting is 55° C for REU-V3232W and 65° C for REU-V3232WC. The unit can be ordered from Rinnai to be pre-set
to any of the other temperatures listed. The unit can be pre-set to any of the temperatures listed by a suitably qualified person, except 95° C.
Conversion to 95° C must be performed by Rinnai.
Controllers are available with default temperatures up to 75° C. When fitted with controllers, only temperatures not exceeding the default
temperatures can be selected. When fitted without controllers, the unit will deliver water at the default temperature. Controllers are not available
with 85 and 95° C settings.
Note 2: Unit will operate at lower pressures but the maximum rated flow of 32L/min. will not be achieved.
Note 3: 95° C setting is not suitable for Flow and Return systems.
Type of appliance Temperature controlled continuous flow gas hot water system
Operation With / without remote controls, mounted in kitchen, bathroom etc.
Exhaust system Forced Flue
