• If this boiler is being installed at an elevation of 2,000
ft. (610m) or higher, disconnect the connector labeled
"High Elevation Disconnect" as illustrated on the right.
This connector is located inside the unit.
• Disconnect power to the boiler before disconnecting
this connector. Failure to perform this step will result in
a "733" code displayed on the boiler control panel and
a cease in operation. If this occurs, disconnect, then
reconnect power to the boiler to reset the system.

Check
• Make sure the boiler is installed securely so that it
will not fall or move due to vibrations or earth-
quakes.
1. Drill a single screw hole, making sure to hit a stud.
2. Insert and tighten the screw and hang the boiler by
the upper wall mounting bracket.
3. Determine the positions for the remaining four screws
(two for the top bracket and two for the bottom), and
remove the boiler.
• The weight of the device will be applied to the wall. If the strength of the wall is not suffi-
cient, reinforcement must be done to prevent the transfer of vibration.
• Do not drop or apply unnecessary force to the device when installing. Internal parts may
be damaged and may become highly dangerous.
• Install the boiler on a vertical wall and ensure that it is level.
