Part 3 - Installation Instructions
A. Wall Mounting the Water Heater
1. Remove the two (2) screws attaching the water heater front cover. Remove the front cover. (Figure 1.)
• Do not install the unit above electrical boxes or junctions.
• The mounting surface must be solid and secure.
2. Position the unit on the mounting surface. Ensure the unit is level. Mount the unit to the wall with four (4)
screws of at least one (1) inch (25.4mm) in length at the marked points. See Figure 2.
Use screws suitable for the wall material and the weight of the water heater. Failure to do so could result in
property damages and damage to the water heater. Such damages ARE NOT covered by product warranty.
• The appliance must be mounted horizontally, with water inlets and outlets at the bottom. See Figure 3.
This water heater must be installed upright in the vertical position as described in this manual. DO NOT attempt
to install this water heater in any other orientation. Doing so will result in improper water heater operation and
property damage, and could result in serious personal injury or death.
