Washington — Ny Thermal Inc. continues to recall select models of its Trinity gas-fired hot water boilers due to potential risk that a condensate fitting in the boiler may prematurely deteriorate, causing a leak and presenting a risk of carbon monoxide exposure to consumers.

The urgent and mandatory safety recall affects only Trinity “Ti” models manufactured between Nov. 28, 2005, and Jan. 8, 2007, or with a serial number greater than 16,000. The manufactured date is located on the white quality control sticker on the back of the cover.

NTI is providing free upgrade kits for all affected units, together with a reimbursement to perform the work. Upgrade kits are available at the company from which the boiler unit was purchased or by calling 800/688-2575.

Individuals who are unsure if a unit falls between the specified dates are asked to contact NTI and provide the serial number displayed on the silver decal on the boiler's outer casing (Example: 06T-16001). Typically, all units that have serial numbers greater than 16,000 are included in the recall.
