EARTHQUAKE ZONES

When installing the heater, consideration must be given to proper location. Location selected should be as close to the wall as practicable and as centralized with the water piping system as possible.

FIGURE 5

Minimum clearances between the water heater and combustible construction are 0 in. at the sides and rear, 0 in. (0cm) from the front and 2 in. (5.08cm) from the top (see Figure 5). If clearances stated on the heater differ from these distances, install water heater according to clearances stated on the heater.

Adequate top clearance of 24 in. (61cm) for servicing this appliance, such as changing the anodes etc., should be considered before installation.

A minimum front clearance of 20 in. (51cm) and 10 in. (26cm) of side clearance must be allowed for access to replaceable parts.

EARTHQUAKE ZONES

In Earthquake Zones the water heater must be braced, anchored, or strapped to avoid moving during an earthquake. Contact local utilities for code requirements in your area. The Spacemaker® TSE25 Bear Claw™ Water Heater Strap is suitable for bracing the Hybrid water heater. Follow the manufacturer’s instructions for installing the braces. Be sure to wear protective goggles and gloves when handling any kind of sheet metal product.

Tabs have been provided on each side of the rear portion of the shroud. The top and bottom of each tab must be cut and gently bent “inwards” thus allowing the straps to exit the shroud (see Figure 9).

In order to access the tabs and install the earthquake straps it is necessary to remove the top, front and side panels of the shroud as follows (see Figures 6 - 8):
