Rinnai America Corporation is providing this guidance to our distributors, installing contractors and consumers who have products that were impacted by the high gas pressure incident in the Merrimack Valley, Massachusetts area.  Although this incident was in no way caused by or related to Rinnai’s product quality, it is Rinnai America Corporation’s policy to put our customer first and be proactive in providing any information that could potentially impact the performance of the products we manufacture and distribute.
