Urgent Product Service Notification – HC 33-160 & DC 33-160

HC 33-160 & DC 33-160 – Heat Exchanger Gasket Upgrade Program

Download printable PDF notice here 

It has come to our attention that a small number of HC 33-160 & DC 33-160 series boilers, manufactured before November 2016, have experienced a heat exchanger gasket failure.  The gasket seals the heat exchanger to the heat exchanger front cover.

In all known cases, the gasket deterioration and failure has been attributed to a lack of annual service in conjunction with a high number of burner operating hours.  In extreme cases, the heat exchanger cover may warp and cause a leak or jacket discoloration, resulting in boiler shut down.

All HC and DC series appliances must be maintained and serviced annually by a licensed technician to ensure the appliance remains in an optimal operational state. If there is any concern about the appliance’s operating condition, turn off electrical power and gas supply and contact your heating contractor to have the appliance inspected.

Identifying the Appliances:

The affected HC 33-160 & DC 33-160 appliances were produced between July 2014 and November 2016, and can be identified with the date code in the serial number on the rating plate.

The rating plate is located on the outer right side of the appliance.

Serial numbers affected include:

HC 33-160 – 051577-1410k00314 to 051577-1611k04482

DC 33-160 – 051537-1407k00001 to 051537-1611k04200

The serial number is located on the rating plate and includes the date of manufacture.
