Heater placement and clearances

WARNING:
▶ The water heater with recess box accessory is
intended for an outdoor installation only.
The water heater is approved for installation on a combustible wall (see
chapter 5.4 Mounting installation) provided the floor covering below the
heater is noncombustible. For installations in an alcove or closet,
maintain the minimum clearances to combustible and non-combustible
materials. See chapter 3.5, page 10.
Do not install the Recess box:
• Under a deck or patio.
• Side of the building with prevailing winter winds.
• Close to plants or trees.
• In areas where people or animals can accidentally touch louvered
exhaust openings.
• Maintain a clean area in front of the appliance of 4 feet (1,2m).
The Recess box should be installed so the discharge vent maintains the
minimum allowable clearances as required by the local authority. Where
no local requirement exists, maintain the following minimum suggested
clearances from builing openings as shown in fig. 16.

outdoors. Do not install the recess box in another
configuration. Damages resulting from an improper
installation will not be covered by Bosch limited
warranty.
