Do not use any sprays, chlorine containing agents, solvents, paint etc. around the boiler or around the air intake supply entrance of the boiler. These

substances have negative inuences on the boiler

and can lead to corrosion resulting in failure of the boiler.

Products to avoid present in boiler room and/or around combustion air intake

Spray cans containing chloro-/fluorcarbons Ammonium and/or ammonium solutions Permanent wave solutions (hair product) Chlorinated waxes and/or cleaners Swimming pool chemicals based on chlorine Calcium chloride used for thawing Sodium chloride used for water softening Refrigerant leaks Paint or varnish removers Hydrochloric acid/muriatic acid Cements and glues Antistatic fabric softeners used in clothes dryers Chlorine-type bleaches, detergents, and cleaning solvents found in household laundry rooms

Checking the water pressure

Check the water pressure in the central heating installation regularly.

Use only potable water for lling.

Additives only after clearance by Rinnai. Contact your installer in case of doubt.

Description of the boiler

The Rinnai E boiler is a room sealed, condensing and modulating central heating boiler with an integrated hot water facility.

The boiler is provided with a integrated control system. Because an outdoor sensor is connected to the boiler, the boiler works weather dependantly. This means that the boiler control measures the

outside temperature and ow temperature. With this data the boiler calculates the optimal ow

temperature for the installation.

When the boiler is connected to an RS100 room thermostat information can be retrieved from the boiler. For more information about the Rinnai thermostats. Please refer to the user manuals.

RS100

On the bottom left side of the front panel there is a small door. Through the transparent panel you can see the boiler status on the display. After opening

this door you will nd the function buttons.

On the following pages you will nd the explanation

of the function buttons and display messages.

Explanation of the function buttons

NOTICE

When the pump is switched on continuously it can lead to undesired heating up of the central heating system during the summer.

Operating instructions Rinnai E-Series

Only licensed professionals who are trained for these boilers are permitted to make alterations in the controller to program the boiler to the installation.

1. Display.

See following pages for further information.

2. ON-OFF Switch (Placed separately next to the boiler). This switch turns the power supply

to the boiler on or off.

3. Central Heating program button.

Switching the Central Heating on or off (Led

on/off);

4. Hot Water program button.

Switching the Domestic Hot Water (DHW)

facility on or off (Led on/off);

5. Pump program button.

When the pump program LED is ON, the pump is switched into a continuous circulation mode. When the pump mode is switched OFF, LED is off the pump is control by the boiler processor. In most situations it is best to leave the pump mode OFF and let the boiler control cycle the pump as needed.

During freezing temperatures it is possible (when there is no outside sensor connected), to manually place the circulation pump in constant circulation mode, thus reducing the chance of freezing pipes (garage, attic or other cold spaces / rooms) which are sensitive to frost.
