INSTALLING THE NEW WATER HEATER

MOUNTING

MOUNTING - DRYWALL (HOLLOW WALL)

1.The selected wall or cabinet must be capable of supporting double the weight of the unit when completely full of water (77 Ibs).

2.The installation area must provide adequate clearances for removal of the front panel and servicing the unit.

3.Locate the wall studs in the area where the unit is to be mounted.

4.Cut two sections of 1/2 inch plywood or equivalent material 3 inches in height. The length of each section should be sufficient to span the width of the wall studs. See Figure 3A.

5.Use appropriately sized nails or wood screws to attach the two wall supports to the wall as show in Figure 3A.

6.Drill two 13/32 inch holes in the upper wall support NOTE: The holes must be level.

7.Insert the hollow wall anchors into the drilled holes. Place the wall bracket over the anchors and screw the two phillips head screws down tight against the bracket.

MOUNTING - MASONRY WALL (SOLID WALL)

1.The selected wall or cabinet must be capable of supporting double the weight of the unit when completely full of water (77 Ibs).

2.The installation area must provide adequate clearances for removal of the front panel and servicing the unit.

3.Drill two 13/32 inch holes in the masonry wall. NOTE: The holes must be level and at least 3-1/2 inches deep.

4.Insert the masonry wall anchors into the drilled holes. Place the wall bracket over the anchors and screw the two phillips head screws tight against the bracket.

MOUNTING - FLOOR

1.The floor selected must be capable of supporting double the weight of the unit when completely full of water (77 Ibs).

2.The installation area must provide adequate clearances for removal of the front panel and servicing the unit.

3.Place a suitable drain pan under the unit. The pan must limit the

water to a maximum depth of 2-1/2 inches and be 2 inches wider than the unit. The pan must also be piped to an adequate drain. See Figure 3B.

Water Piping

HOTTER WATER CAN SCALD:

Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, cleaning and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally disabled. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve should be used at the hot water taps used by these people or at the water heater. Valves for reducing point of use temperature by mixing cold and hot water are also available.

Consult a Qualified Installer or Service Agency. Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual.
