Part No. 650-000-221/0298 AlumiPex Radiant Tubing AlumiPex Radiant Tubing Hazard Definitions Indicates presence of hazards that will cause severe personal injury, death or substantial property damage. Indicates presence of hazards that will or can cause minor personal injury or property damage. Codes and Standards • This guide is provided for general information only. The building or heating system designer is responsible for all design details and for compliance with all building codes, local and national. • Refer to AlumiPex Technical Information sheets for specific approvals and listings of AlumiPex Radiant Tubing. Indicates presence of hazards that can cause severe personal injury, death or substantial property damage. Indicates special instructions on installation, operation or maintenance that are important but not related to personal injury or property hazards. • AlumiPex Radiant Tubing is not approved for potable water applications. • Consult local requirements before installing a radiant heating system. Install AlumiPex tubing following all of the applicable codes and all specifications and methods prescribed by the building designer and heating system designer. Do not use AlumiPex Radiant Tubing to conduct natural gas. Such an application could result in severe personal injury, death or substantial property damage. Do not expose AlumiPex Radiant Tubing to petroleum products or solvents. Do not weld or glue AlumiPex. Do not secure AlumiPex tubing permanently with adhesive tape. The tubing could be damaged, resulting in risk of severe personal injury, death or substantial property damage. Finished Flooring: Use only finished flooring rated by the flooring manufacturer for use with heated floors. Failure to follow this guideline could result in substantial property damage. Do not use AlumiPex Radiant Tubing in potable water or combination space heating/ potable water heating applications. The tubing is not approved for domestic water use. In combination space heating/potable water heating applications, chemical or biological contamination in the system water is possible and could result in severe personal injury, death or substantial property damage. Use only AlumiPex Fittings with AlumiPex Tubing. Use of any other method can result in severe personal injury, death or substantial property damage. This installation guide covers both new construction and retrofit. For retrofit of a completed building review the Trade Guides with the building owner if there is no general contractor involved in the remodeling project.

Finish Flooring Part Number 650-000-221/0298 AlumiPex Radiant Tubing AlumiPex Radiant Tubing A. Tube Layouts for Radiant Heating 1. Radiant Floor Heatng a. Hot water flowing in the radiant tubing under the finished flooring heats the flooring and the heat emission plates. The heat emission plates help spread the heat evenly across the flooring. b. Heat must pass through the flooring and the coverings on the floor (low pile carpeting and thermal pads, for example). See Figure 1. • The more the flooring and coverings act as insulators, the higher the tube water temperature has to be to cause the floor surface to heat up. • Heavy carpeting and pads resist heat transfer and are not recommended for use in radiant floor heating. c. Heat will also try to move downward. • In suspended floor applications, heat will try to pass to the space underneath. So insulation is needed under the floor to prevent this...
