To install on carpeted area you must install a metal or wood panel under the water heater
that extends at least 3 inches beyond the width and depth of the unit. If water leakage can
result in damage to the adjacent area, install a drain pan that can be drained to outside of
the vehicle, under the water heater.
Verify that a clearance of 1 inch will remain after installation between the top surface of the
water heater and any combustible material. 0 inch clearance is acceptable for the sides.
Make sure that the front edge of the opening is surrounded by a solid frame to firmly
anchor the water heater; if needed, build an appropriate frame using 2" X 2" elements
(Figure 1)
The rough opening for the GSWH-1M should be 12.75" X 12.75" with right angle corners.
The exterior wall opening must be the same dimensions with no radius corners.
