NOTICE

Rinnai supplies specific Plumbing Kits with each boiler type, which must be fitted 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 filter to allow the filter to be cleaned.

-Position 3 (figure 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 (figure 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 fill, please see the

Rinnai Boiler Applications Manual.

Thoroughly flush 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 fittings, supplied with the boiler (fig. 5, pos. 4) first 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.
