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
