REU-2532W Series 6 Rinnai

2. Features

Installation

The lightweight, slim, compact design enables ease of installation and improved appearance. The remote

controls (where fitted) are connected to the appliance by (2) core non-polar cable, or low voltage

thermostat wire, ensuring easy wiring and eliminating problems of mis-connections. Since the remotes

use a 12 VDC digital signal, there’s no-way you can cross up the wiring. You can connect the black

wires to black wires at one terminal, black and white at another, and still not short the units out.

Low Noise Level

Low noise level design enables these appliances to be installed in apartment units, townhouses, and

other high density residential areas with little concern about noise disturbances.

Safety

Various safety devices controlled by a micro- computer ensure complete safety. Also, the anti-frost

device automatically prevents the water inside the appliance from freezing by using small electrical

ceramic heaters, connected to the pipe-work at strategic locations throughout the appliance. The unit has

a secondary freeze prevention device that will allow the unit to fire for three seconds if the water

temperature inside the appliance drops below 37 °F. This mode will heat the water inside the unit back

up to 57 °F. The anti-frost devices should prevent the unit from freeze-ups down to the –30 °F, in a no

wind situation. This feature functions as long as the unit has power and gas.

Economy

Direct ignition to the main burner eliminates wasteful pilot gas consumption. The combustion fan rpm is

proportionally controlled with the gas consumption. This maintains high energy efficiency, as the gas

consumption changes with increased or decreased water flows. The unit’s thermal efficiency rating is;

0.85 for (LP) units and 0.79 for natural gas units.

Water Supply Control

The water supply capacity varies proportionally from 0.5 to 8.5 GPM’s. A suitable volume of hot water

can be supplied throughout all seasons by the water flow control device and water flow

servomechanism. The Continuum 2532 series will supply up to 6.5 GPM’s at a 50°F rise or up to 8.5

GPM’s at a 35 degree rise, controlled by an automatic electro-mechanical water control flow device.

Details pertaining to water flows can be found in the water flow charts in this manual.
