DOOR/FLANGE ASSEMBLY - Part #1GWHDA6

The existing cut out for a 6 gal Atwood water heater measures 16 1/4” (W) by 12 5/8” (H).

The cut out needed for your GSWH-1 is only 12 ¾” by 12 ¾” and its flange MUST be supported on all
sides by a wooden frame so that it may be mounted rigidly with #8 ¾” flat head screws.

The flange will fit vertically into the existing opening, but a horizontal gap of 3 ½” will be left between
the new flange and the side of the opening.

A properly cut piece of 2” by 2” must be added as a vertical brace located at 12 ¾” from the right edge
of the cut out. (See Fig. 1)

Please refer to the Owner’s Manual for information on how to complete the installation.
