6.1.1 Plumbing Kit installation
Rinnai supplies specic 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 result in the void of 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 house 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. 5, pos. 4) rst to the
Plumbing Kit and then to the boiler.
- Connect the expansion tank to the system. See chapter 6.2.
- Connect the pipes so that they are free from strain.
