Part 3 Execution

3.1 PIPING APPLICATIONS

.1 Drawing plans, schematics, and diagrams indicate general location and arrangement of

piping. Indicated locations and arrangements are used to size pipe and calculate friction




loss, expansion, and other design considerations. Install piping as indicated unless

deviations to layout are approved on coordination drawings.

.2 Installers shall be trained and certified to install the pipe according to the manufacturer’s

guidelines. Contact your local Aquatherm representative for training.

.3 Install listed pipe materials and joining methods below in the following

applications:

.1 Underground Piping: Polypropylene (PP-R) piping in SDR 7.4, 11, or 17.6 per

manufacturer’s instructions and ASTM D2774.

.2 Aboveground: Polypropylene (PP-R) piping in SDR 7.4, 11, or 17.6 based on the

required minimum pressure rating and use temperature, in accordance with

manufacturer’s instructions and ASTM F2389.

.4 Installation must be accomplished with the proper tools for installing Aquatherm piping

following manufacturer’s instructions. Installation tools are available from your local

Aquatherm representative. Tools may be purchased or rented.

.5 Install hydronic piping level and plumb.

.6 Install piping indicated to be exposed and piping in equipment rooms and service areas at

right angles or parallel to building walls. Diagonal runs are prohibited unless specifically

indicated otherwise.

3.2 FUSION WELDING OF JOINTS

.1 Install fittings and joints using socket-fusion, elecrofusion, or butt-fusion as applicable for

the fitting or joint type. All fusion-weld joints shall be made in accordance with the pipe

and fitting manufacturer’s specifications and product standards.

.2 Fusion-weld tooling, welding machines, and electrofusion devices shall be as specified by

the pipe and fittings manufacturer.

.3 Prior to joining, the pipe and fittings shall be prepared in accordance with ASTM F 2389

and the manufacturer’s specifications.

.4 Joint preparation, setting and alignment, fusion process, cooling times and working

pressure shall be in accordance with the pipe and fitting manufacturer’s

specifications.

3.3 VALVE APPLICATIONS

.1 Install gate valves close to the main on each branch and riser serving 2 or more equipment

connections and where indicated.

.2 Install gate or ball valves on the inlet to each equipment item and elsewhere as indicated.

.3 Install drain valve at the base of each riser, at low points of horizontal runs, and where

required to drain hydronic piping system.

.4 Install swing check valve on the discharge side of each pump and elsewhere as indicated.

.5 Install ball valves in each hot-water circulating loop and the discharge side of each

pump.



3.4 PIPING INSTALLATIONS

.1 Fire stopping shall be provided to both be compatible with the Aquatherm Piping and

meet the requirements of ASTM E 814 or ULC S115 , “Fire Tests of Through-Penetration

Firestops”. Pipe insulations or fire resistive coating shall be removed where the pipe

passes through a fire stop and, if required by the firestop manufacturer, for 3 inches

beyond the firestop outside of the fire barrier.

.2 When installed in systems with pumps in excess of 7.5 HP, piping shall be protected from

excessive heat generated by operating the pump at shut-off conditions. Where the

possibility exists that the pump will operate with no flow, the protection method shall be a

temperature relief valve or comparable level of protection, set to a maximum temperature

of 185°F.

.3 If heat tracing or freeze protection is specified for the piping, it should be installed

on the pipe interior or exterior. It must be suitable for use with plastic piping and

be self-regulating to ensure that the surface temperature of the pipe and fittings

will not exceed 70°C (158°F).

3.5 HANGER AND SUPPORT INSTALLATION

.1 Comply with requirements for seismic-restraint devices in Section 13 48 00 and

Section 13 48 01.

.2 Comply with requirements for pipe hanger, support products, and installation in

Section 23 05 29 "Hangers and Supports for Plumbing Piping and Equipment."

.1 Vertical Piping: MSS Type 8 or 42, clamps.

.2 Individual, Straight, Horizontal Piping Runs:

.1 Adjustable, steel clevis hangers.

.2 Clamps on strut trapeze.

.3 Clamps on strut attached to structure.

.4 Clamps attached directly to the structure.

.3 Base of Vertical Piping: MSS Type 52, spring hangers.

.4 Support vertical piping and tubing at base and at each floor. For piping 2” (63mm)

or smaller, install mid-story guides.

.5 Install hangers and supports at intervals specified in the applicable Plumbing Code and/or

as recommended by pipe manufacturer.

.6 For hot water piping, provide clamps and supports that are felt or rubber/vinyl coated or

lined.

.7 For cold water piping supports and clamps may be bare metal. Ensure that the clamp or

support does not have sharp edges that may scrape or gouge the piping.



.8 Use care when installing riser clamps to not over tighten the clamps to cause indentation

of the pipe. Riser clamps shall be isolated from the building structure by placing felt or

rubber pads between the clamp and the structure.

.9 All piping support materials shall be new and manufactured for the specific purpose of

supporting systems, equipment, pipes and accessories. No improvised pipe support

solutions shall be allowed.

.10 Piping systems shall not have direct contact with the building structure. Provide

isolation at tub and shower valves and pipes passing through studs, joists or

plates. Use iron pipe sizes to fit Aquatherm pipe. Acceptable manufacturers for

pipe/structure isolation:

a. Holdrite

b. Oatey

c. Sioux Chief

3.6 EXPANSION AND CONTRACTION

.1 Provide expansion and contraction controls, guides and anchors to take into account the

expansion and contraction of the pipe. Provide expansion loops or offsets as required and

as indicated in the manufacturer’s literature.

.2 While Aquatherm MF (faser) piping can absorb most of their own expansion stresses, this

can cause the pipe to bow or bend.

.3 Install anchor points at least every 120 feet.

.4 Install expansion loop or offset between each anchor point. Expansion device must be able

to absorb all of the stresses between the two anchor points. Refer to manufacturer’s

published instructions, formulas and calculations at www.aquatherm.com.

.5 Non-MF pipes used for hot applications shall have expansion controls every 30 feet of

straight runs.

.6 Vertical risers of MF piping shall be anchored at each floor.

.7 Provide anchor point at branch take-off in vertical riser of MF piping.

3.7 PRESSURE TESTING

.1 While still accessible all piping shall be pressure/leak tested to the manufacturer’s

standards.

.2 Tests shall be carried out using water, compressed air or a mixture of the two. The test

pressure shall be as indicated in the pressure leak testing procedures required by the

manufacturer.

.3 Any leaks detected shall be repaired at the contractor’s expense by removing the leaking

part and replacing with new parts welded per the pipe manufacturer’s guidelines. See

www.aquatherm.com for additional details and forms.



3.8 INSPECTING AND CLEANING

.1 The pipes shall be flushed with cold water after finishing the installation. Flush the system

until the water runs clear of debris and dirt.

.2 Inspect and test piping systems following procedures of authorities having jurisdiction and

as specified by the piping system manufacturer.

.3 Clean and disinfect water distribution piping following procedures of the manufacturer

and/or the authority having jurisdiction.

3.9 CIRCUIT BALANCING VALVES

.1 Install flow balancing valves where indicated.

.2 Remove handwheel after installation and when TAB is complete.

.3 Tape joints in prefabricated insulation on valves installed in chilled water mains.
