glycol HTF. A thorough cleaning is required

before charging the system with propylene gly-

col. Carefully review the cleaning procedures in

“Charging the System” outlined in section 4.14.
All vertical piping between the storage tank

and the collector shall be supported at each

story or at maximum intervals of ten feet (10’).

Horizontal pipe runs should be supported to

allow complete drainage of the system if nec-

essary, the recommended slope is ¼” per foot

sloped to drain.
Horizontal roof runs shall be secured and sup-

ported providing at least 1 ½ inches clearance

from the roof. Standard best piping practices

shall be followed as described in the Uniform

Plumbing Code, International Plumbing Code

or other recognized code or standard. Plumbers

tape or tube strap is required. The pipe insula-

tion should not be compressed or crimped by

the strapping material.
Only Solder Fluxes meeting the criteria of

ASTM B 813 should be utilized for joining by

soldering any copper and copper alloy tube and

fittings in the entire solar system.
Allowance should be made for expansion and

contraction of piping due to changes in tem-

perature of the HTF and piping. Use flexible

pipe supports and avoid long straight piping

runs. Soft copper coils or other flexible piping

is recommended, if hard copper is used include

bends and elbows to allow for expansion such

as swing joints at the collector inlet & outlet.
The installation of all horizontal and vertical

piping shall not reduce the performance or

rating of any structural member or fire rated

assembly. Adhere to all applicable local codes

and ordinances.

4.5 Pipe Insulation
WARNING: HOT PIPES MAY CAUSE

BURNS IF TOUCHED. ENSURE THAT

ALL PIPES AND FITTINGS ACCESSIBLE

TO THE PUBLIC ARE WELL INSULATED.

COMPONENTS ACCESSIBLE TO PUBLIC

TRAFFIC MUST BE KEPT BELOW 140ºF

OR CLEARLY LABELLED WITH AN

APPROPRIATE WARNING.
