If you have a gas direct vent fireplace that you believe may require the retrofit, the following information will help confirm whether your gas fireplace is one of the installations requiring the retrofit.

The safety concern and retrofit only applies to specific models of Marco gas fireplaces. You will need to attain the specific model number on your fireplace. This information can be found on the silver 3" x 5" metal or foil identification plate that is located inside the lower grille or access panel at the right side bottom of the fireplace as you face the fireplace. The grille or panel is hinged at the bottom and can usually be opened with your fingertips. In some cases, it may be necessary to use a flat blade screwdriver or key to open and lower the panel.

The six-digit model number required starts with either a 794 or 797 as the first three numbers. It can be found near the top of the label and may require a flashlight to see the numbers. Please write down all six-digits of the model number including any letter following after the last number. This information is NECESSARY in order to properly identify your fireplace.

Please select your fireplace model.
