AlumiPex Radiant Tubing

I.Install the Tubing

Always wear safety glasses for eye protection when handling AlumiPex tubing. The tubing can spring back when pulled. Failure to follow this guideline could result in serious personal injury.

1.

Install the sleepers.

 

• Beginning from one side of each room, use your

 

floor markings and the tube layout drawing to

 

place the sleepers.

 

• Glue and nail each sleeper in place as shown in

 

Figure 10.

 

• Bend routing sleepers can be made using a router

 

and fixture as shown or using a saber saw to cut

 

semicircles.

2.

Drill tube penetration holes.

 

• If the tubing will penetrate the floor in the room,

 

drill a 1½” hole at a 45 degree angle for each

 

penetration as shown in Figure 9.

 

• Make sure the tube can be routed through the hole

 

from below and provide a minimum 6 inch bend

 

diameter (3 inch bend radius) for 1/2” tubing.

3.

Install heat emission plates.

 

• Install AlumiPex Heat Emission Plates in the

 

sleeper spaces, centered in the 1” gap.

 

• Secure heat emission plates on one side only to the

 

sleeper below using 5/8” staples.

 

• Leave the other side of the heat emission plates

 

free to move so the plates can conform to the floor

7.Attach tube fitting to manifold SUPPLY connection (bottom manifold).

8.Feed the tubing to the room as shown on the heating system designer’s tube layout drawing, feeding the outer (SUPPLY) tubing first.

9.Complete the layout for the circuit and route the tubing back to the return manifold as shown on the tube layout drawing.

10.Carefully cut the tubing to the correct height at the return manifold. Apply an AlumiPex fitting for attachment to the manifold.

11.Then attach the fitting to the RETURN (top) manifold.

12.Continue the process for each circuit.

13.See Figure 11, page 16, for an above floor construction example.

4.

Place tube roll on uncoiler.

5.

Route free end of tubing to manifold.

 

• Feed the free end of the tubing through any

 

penetration holes to the manifold.
