Z21.10.3 – latest edition.

Before locating the water heater, check:

1. Check for nearby connection to:

• Water piping

• Venting connections

• Gas supply piping

• Electrical power

2. Locate the appliance so that if water connections should

leak, water damage will not occur. When such locations

cannot be avoided, it is recommended that a suitable

drain pan, adequately drained, be installed under the

appliance. The pan must not restrict combustion air

Closet and alcove installations

A closet is any room the water heater is installed in which is less than 86 cubic feet for AWN151 models, 106 cubic feet for AWN200models, 120 cubic feet for AWN286 models, 165 cubic feet for AWN400 models, 191 cubic feet for AWN501 models, 223 cubic feet for AWN601 models, 247 cubic feet for AWN701 models and 278 cubic feet for AWN801 models.

An alcove is any room which meets the criteria for a closet with the exception that it does not have a door.

Example: Room dimensions = 4 feet long, 5 feet wide, and 9 foot ceiling = 4 x 5 x 9 = 180 cubic feet.
