ELX Flue Grommet Upgrade


We at HTP have discovered a potential issue with a Grommet Seal in the select HTP Elite XL Commercial high efficiency condensing boilers and volume water heaters.

Specifically, a Grommet Seal affixed to the flue discharge pipe and temperature probe inside the product can degrade and crack as a result of prolonged exposure to corrosive flue gases. For the safe and efficient operation of the boilers, we have decided to issue an Important Safety Upgrade, whereby the Grommet Seal on all affected products will be replaced with a new Grommet Seal from a different material.

The Grommet Seal in question can be found inside the affected boilers (see Before picture) and the upgrade requires installation of a band to secure the grommet (see After picture).
