**Federal Tax Credit Information:

The purchase and installation of this energy-efficient product in your home qualifies you for the Federal Tax Credit for Consumer Energy Efficiency. The credit is worth 30% of the item's total cost, up to a maximum of $1,500 and is only applicable on products placed in service in an existing home and your principal residence starting January 1, 2009, through December 31, 2010.

Since this non-solar gas water heater has either an Energy Factor ≥ 0.82 or a thermal efficiency of at least 90%, it qualifies for the Federal Tax Credit. The tax credit also includes installation costs.

To apply for the tax credit, you must file and submit the relevant tax forms. For products "placed in service" in 2010, you would take the tax credit on your 2010 income taxes. Remember to save your receipts and the Manufacturer's Certification Statement for your records.
