Important: | Figure1: Minimum Clearance Locations | |
The water heater should be located in an area where |
|
|
leakage of the tank or connections will not result in dam- |
|
|
age to the area adjacent to the water heater or to lower |
|
|
floors of the structure. Due to the normal corrosive | Back | Sides |
action of the water, the tank will eventually leak after |
| |
an extended period of time. A suitable metal drain pan |
|
|
should be installed under the water heater as shown |
|
|
below, to help protect the property from damage which |
|
|
may occur from leaks in the piping connections or tank. |
|
|
The pan must limit the water level to a maximum depth of |
|
|
1 3/4 inches (45mm) and be 2 inches (51mm) wider than |
|
|
the water heater and piped to an adequate drain. The |
|
|
pan must not restrict combustion airflow. Locate the |
|
|
water heater near a suitable indoor drain. Outside drains |
|
|
are subject to freezing temperatures which can obstruct | Top View | Front 24” min. |
the drain line. The piping should be at least 3/4” (19mm) |
| for service |
ID and pitched for proper drainage. Under no circum- |
| Vent |
stances will the manufacturer or seller of this water heater |
|
|
be held liable for any water damage which is caused by |
|
|
your failure to follow these instructions. |

Clearances and Accessibility
Notice: Minimum clearances from combustible materials are stated on the data plate located on the front of the water heater.

|
|
|
|

|
|
|
|
|
|
|
|
the water heater to maintain 6 inches (150mm) |
