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 engineered 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 ef ciency. The condensate, which has
no effect on the heat exchanger and the function of the boiler, is drained through a
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.

6 Connecting the boiler
The boiler has the following connection pipes;
- The central heating circuit pipes.
These must connected to the plumbing kit by means of adapter ttings.
See further chapter 6.1;
- The gas supply pipe.
It is provided with a 3/4" male thread into which the tail piece of the gas valve can
be screwed. See further chapter 6.4;
- Cold and hot water pipes for domestic hot water (DHW).
These consist of 3/4" (15 mm) copper pipe and can be connected to the installation
by means of 3/4" M-NPT adapter ttings. See further chapter 6.5;
- The condensation drain pipe.
It consists of an oval 1" (22 mm) plastic pipe. The drain pipe can be connected to
this by means of an open connection. If the open connection is tted in a different
location, then the pipe can be lengthened by means of a 1 1/4" (32 mm) PVC
sleeve. See further chapter 6.6;
- The vent system and air supply system.
It consists of a concentric connection 3"/5" (80/125 mm). The boiler can be converted
to a twin pipe connection that will accept 80mm ue and intake air or with the use
of the included adapters 3” PVC/CPVC ue and intake. See further chapter 6.7.
The pipes to be connected to the boiler must be cleaned before connecting in
order to prevent dirt from entering and damaging the boiler.
6.1 Central heating system
Connect the central heating system according to its instructions.
The boiler pipes can be connected to the installation by means of compression ttings.
Reducers should be used for connecting to thick-walled pipe (welded or threaded).
When removing the plastic sealing caps from the pipes, dirty testing water
may drain from the boiler.
A Plumbing Kit must be tted to the boiler.
The boiler, when used in connection with a refrigeration system, must
be installed so the chilled medium is piped in parallel with the boiler with
appropriate valves to prevent the chilled medium from entering the boiler.
The boiler piping system of a hot water boiler connected to heating coils
located in air handling units where they may be exposed to refrigerated air
circulation must be equipped with ow control valves or other automatic
means to prevent gravity circulation of the boiler water during the cooling
cycle.

6.1.1 Plumbing Kit installation
Rinnai supplies speci c Plumbing Kits with each boiler type, which must be tted
directly underneath the boiler on the supply and return pipe. Use of the Rinnai boiler
without the plumbing kit will void the warranty.
To protect the entire heating system we recommend installing a dirt particle
trap in the return circuit. When the boiler is installed to an existing heating
system this trap is required. Use of a Y strainer is not permitted as substitute
for a dirt trap.
- Install shut-off valves immediately before and after the dirt particle lter to allow
the lter to be cleaned.
- Position 3 ( gure 6) is a garden hose thread boiler drain, that can be used to drain
the boiler or add water tratment additives to the system, such as inhibitors or glycol.
- Position 4 ( gure 6) is the supply connectionfor an idirect tank when used with the
optinal 3-way valve kit.
- For information on locating the expansion tank and system ll, please see the
Rinnai Boiler Applications Manual.
Thoroughly ush all pipes and radiators. We recommend the use of a Rinnai
approved system cleaner. Refer to the Rinnai Boiler Applications Manual for
an approved list of Rinnai system cleaners.
- Refer to the installation template and chapter 5.3 for the pipe connection
dimensions.
- Fit the bronze adapter ttings, supplied with the boiler ( g. 6, pos. 4) rst to the
Plumbing Kit and then to the boiler.
The plumbing kit is not intended to support the weight of the piping. Appropriate
piping supports should be used to support all attached piping to the boiler and
plumbing kit.
