Flooring
The Shield water heater is approved for installation on combustible flooring, but must never be installed on carpeting.
WARNING Do not install the water heater on carpeting even if foundation is used. Fire can result,
causing severe personal injury, death, or substantial property damage.
When local codes require compliance with NSF 5, the heater must be sealed to the floor with a food grade silicone to prevent debris and harborage of vermin under the heater.
If flooding is possible, elevate the water heater sufficiently to prevent water from reaching the water heater.

1.Remove the sides and the top of the crate.
2.Remove the blocks on the base of the crate to allow for easier removal.
3.The water heater can then be slid off the base of the crate for installation.
