Plumbing Installation

!CAUTION: Plumbing must be installed so that the performance of any fire rated assembly is not reduced.

NOTICE: The location of the roof jack may vary depending on installation type.

NOTICE: The closed loop piping between the storage tank and solar collectors does not require insulation.

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

1.Review checklist sketches for roof- jack location.

2.Mark on the roof the exact location of roof-jack installation.

3.Install plumbing according to type of installation on page 17 & 18 and plumb lines to roof according to Key to Stub-Outs.

External Piping Insulation

•Where potable water piping is in an external location or attic space where the temperature can be as low as 19°F it must be insulated with a minimum ¾” Armaflex (or similar) flexible elastomeric closed cell thermal insulation. Where the temperature can fall to 12°F the insulation thickness must be increased to 1 ½”.

•It is recommended that electrical heat tracing be installed on potable water piping in areas where the temperature falls below 32°F for more than 4 hours with no hot water draw to protect against pipe freezing.

•Insulation in external locations can deteriorate through UV radiation. To prevent this, a layer of outdoor UV stable paint or other similar protective coating must be applied to the insulation.

The following may be performed in any order necessary:

• If water pressure exceeds 60 psi,

install optional Pressure Regulator on main supply to building.

•Connect the outlet of the T/P and pressure relief valve to a suitable open drain so that the discharge water cannot contact live electrical parts and to eliminate potential water damage.

!DANGER: Hotter water increases the potential for Hot Water SCALDS.

•Piping used should be of a type approved for hot water distribution.

•The discharge line must not be smaller than the outlet of the valve and must pitch downward from the valve to allow complete drainage (by gravity) of the relief valve and discharge line.

•The end of the discharge line should not be threaded or concealed, and should be protected from freezing.

•No valve of any type, restriction or reducer coupling should be installed in the discharge line.

NOTICE:

1.All plumbing installation must conform to local codes.

2.All piping must be adequately supported, supports must conform to local codes.

3.All piping must be adequately insulated, insulation must conform to local codes.

4.All piping must slope to drain.
