With a roof vent pipe of 3" (8cm) in diameter, the collec-

tors can be positioned on either side of the vent. Two sys-

tem connector hoses (Part #60649-1/-2) can be employed

to couple the collectors together for vent pipes or other

obstacles up to 7" (17cm) in diameter. Mark your 51"

(1.3m) centers wherever the outlet header brackets 'fall'

on the upper chalk line. With obstructions of over 7"

(17cm), such as attic fans and skylights, lay out the col-

lectors on either side of the obstruction using a Row

Spacer Kit (Part #12017-1 for 1 1/2"; #12017-2 for 2").

System Piping

Refer to Figures 10 & 11, throughout this section. The

most common piping configurations use a pressure filter.

The pump draws the water from the skimmer and/or a

main drain, forcing it through the filter and sending it back

to the pool through the return lines.

If a fuel-fired heater is installed, it is located between the fil-

ter and the return line to the pool. The pipes to and from the

solar collectors are connected to the return line to the pool

before the water enters the fuel-fired heater, if one is used.

SCHEMATIC

Whenever there is more than 40 gpm (151.6

flow rate to the collectors or more than 100' (12m) of pip-

ing used in a system, install 2" (63mm) piping to and from

the collectors.

Piping to and from the collectors should be the same type of

plastic piping and fittings approved for use with swimming

pool filters and pumps. It is recommended to always use

Schedule 40 PVC pipe and fittings. Although PVC pipe is

generally white, black is also available but may be difficult to

find locally. If for aesthetics black pipe is desired it can

always be painted black. Use a PVC cutter or a PVC wide-

blade saw (not a hacksaw) for cutting pipe. It is important to

use both a quality cleaner/primer and solvent in gluing a PVC

joint. For more detailed information on PVC gluing refer to

Engineering Bulletin No. 8701. Finally, use a cloth while

either gluing or painting to keep the job a clean one. Piping

should also be supported at intervals of 5' (1.5m) for hori-

zontal pipe and 8' (2.5m) for vertical pipe. Use either galva-

nized or plastic pipe clamps. Aquatherm Industries outlet

header bracket assemblies (Part #10008-1/-2), which are

made of stainless steel, are also excellent pipe hangers.
