Description of the boiler

Room sealed boiler
The boiler retreives its com-
bustion air from outside then
discharges the flue gasses to
the outside.
Condensing
Retrieves heat as much as
possible from the flue gas-
ses. Water condensates on
the heat exchanger.
Modulating
Stepless higher or lower
burning according to the heat
demand.

For direct-vent boilers mechanical-vent heating boilers or domestic hot water
equipment where the bottom of the vent terminal and the intake is installed higher
than four feet above grade the following requirements must comply:
1) If not present on each floor level where there are bedrooms, a carbon monoxide
detector and alarm must be placed in a living area outside the bedrooms. The
carbon monoxide detector and alarm must comply with NFPA 720 (2005 Edition).
2) A carbon monoxide detector shall:
a) Be located inn the room where the boiler and/or equipment is located;
b) Be either hard-wired or battery powered or both; and:
c) Shall comply with NFPA 720 (2005 Edition).
3) A product-approved vent terminal must be used, and if applicable, a product-
approved air intake must be used. Installation shall be in strict compliance with
the manufacturer's instructions. A copy of the installation instructions shall remain
with the appliance and/or equipment at the completion of the installation.
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 efficiency. 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.
