3 Description of the boiler
The Rinnai E boiler is a room sealed, condensing and modulating central heating
boiler, with an integrated DHW fascility.
The boiler is provided with a compact stainless steel heat exchanger with smooth
tubes. This design is a well thought out principle using durable materials.
The boiler burns gas for supplying heat. The heat is transferred in the heat exchanger
to the water in the central heating system. By cooling down the exhaust gases
condensate is formed. This results in high efciency. The condensate, which has
no effect on the heat exchanger and the function of the boiler, is drained through
condensate collector trap.
The boiler is provided with an intelligent control system (CMS Control Management
System). The boiler anticipates the heat demand of the central heating system or the
domestic hot water facility system.
When an outdoor sensor is connected to the boiler it will operate weather dependantly
using outdoor reset. This means that the boiler control measures the outside
temperature and supply temperature. With this data the boiler calculates the optimal
supply temperature for the installation.
Explanation of the appliance type: Rinnai E110CN
E = Type
110 = Nominal load in (x1000) BTU
C = C = Combi
N = Natural Gas (P = Propane Gas)
Different boilertypes:
Room sealed boiler
The boiler retreives its com-
bustion air from outside then
discharges the ue gasses to
the outside.
Condensing
Retrieves heat as much as
possible from the ue gas-
ses. Water condensates on
the heat exchanger.
Modulating
Stepless higher or lower
burning according to the heat
demand.
