Installing the water heater | Rheem RS47-21BP, RS80-42BP specification

Installing the water heater.

The location chosen for the water heater must take into consideration the following:

Local Installation Regulations

This water heater must be installed in accordance with these instructions, local codes, utility codes, utility company requirements or, in the absence of local codes, the latest edition of the National Electrical Code.

It is available from some local libraries or can be purchased from the National Fire Protection Association, Batterymarch park, Quincy, MA 02269 as booklet ANSI/NFPA 70.

!WARNING: Heat trace will not protect against pipe freezing in the event of power loss.

!WARNING: Extended periods of cold weather, including ambient air temperatures below the limits specified on the right, may cause freezing in exposed parts of the system. It is the owner’s responsibility to protect the system in accordance with these instructions if the air temperature is anticipated to approach the specified limits.

Location

Minimum Air Temperature

Rheem Thermosiphon systems must not be installed in areas where the outside air temperature can fall below 41°F continuously for more than 18 hours. Where outside air temperature falls lower than 41°F Rheem closed loop models must be installed. The collector closed loop fluid is freeze protected to -40°F.

If the outside air temperature is to fall below 32°F for more than 4

hours on the Rheem closed loop models, it is suggested that all potable water plumbing is installed with heat trace and insulated to protect against pipe freezing. In the event of a power failure, open a hot water faucet and allow a slow trickle of water to flow until power is restored.

Please contact your service technician for assistance and advice with protection against pipe freezing.

Inspect Shipment

Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain the power supply (Solar Electric Only) corresponds to the water heater requirements. Make sure all parts included with the solar water heater system are accounted for by comparing to the following list of parts.
