PART 2 PRODUCTS

2.01 MATERIALS

A. Infloor High Capacity components: Furnish and install a complete radiant heating panel distribution system that includes temperature gauges on supply and return manifold modules, contaminant screen and flow indicators on supply modules, 1" stainless steel isolation ball valve on supply and return modules with balancing adjustment for each circuit, and a module CV rating of 14.4 or greater. Balance each circuit to maintain even temperature drop in loops. Infloor High Capacity components to be furnished by MAXXON Corporation, Hamel, MN.

B. Infloor tubing: Radiant tubing shall be _____________________. Tubing to be furnished by MAXXON Corporation, Hamel, MN, and is to be installed in complete accord to manufacturer's instructions. Choose one of the following:

1. Infloor barrier cross-linked polyethylene (BPEX) as provided by MAXXON Corporation, Hamel, MN: nominal 1/2" (inch) [13 mm] inside diameter with a nominal 5/8" (inch) [16 mm] outside diameter with a wall thickness of 0.059" (inch) [1.5 mm], rated for 100 psi (689.5 kPa) at 180 degrees F (82.2 degrees C) with an external ethylene vinyl alcohol (EVOH) oxygen diffusion barrier allowing no more than 0.1 gram per cubic meter per day (0.1g/m³/d). Individual circuit length to be up to 450' (feet) [137.2 m] maximum.
2. Infloor barrier cross-linked polyethylene (BPEX) as provided by MAXXON Corporation, Hamel, MN: nominal 3/4" (inch) [19 mm] inside diameter with a nominal 1" (inch) [25 mm] outside diameter with a wall thickness of 0.059" (inch) [1.5 mm], rated for 100 psi (689.5 kPa) at 180 degrees F (82.2 degrees C) with an external ethylene vinyl alcohol (EVOH) oxygen diffusion barrier allowing no more than 0.1 gram per cubic meter per day (o.1g/m³/d). Individual circuit length to be up to 1000' (feet) [304.8 m] maximum.
3. Infloor cross-linked polyethylene (PEX) as provided by MAXXON Corporation, Hamel, MN: nominal 1/2" (inch) [13 mm] inside diameter with a nominal 5/8" (inch) [16 mm] outside diameter with a wall thickness of 0.059" (inch) [1.5 mm], rated for 100 psi (689.5 kPa) at 180 degrees F (82.2 degrees C). Individual circuit length to be up to 450' (feet) [137.2 m] maximum.
4. Infloor cross-linked polyethylene (PEX) as provided by MAXXON Corporation, Hamel, MN: nominal 3/4" (inch) [19mm] inside diameter with a nominal 3/4" (inch) [19 mm] inside diameter with a nominal 1" (inch) [25 mm] outside diameter with a wall thickness of 0.118" (inch) [3.0 mm], rated for 100 psi (689.5 kPa) at 180 degrees F (82.2 degrees C). Individual circuit length to be up to 1000' (feet) [304.8 m] maximum.

C. System Controls: space temperature to be maintained by using floor sensor and outdoor sensor connected to reset controller. Reset controller shall operate circulating pump(s) and boiler to maintain slab temperature in relation to changes in outdoor temperature. When used with a non-condensing boiler, a tempering valve shall be used to maintain the secondary loop delivery water temperature. Consult the Infloor Design and Installation Guide as provided by MAXXON Corporation, Hamel, MN.

D. Primary boiler loop and circulating pump: Primary circulating loop shall be supplied by others with sufficient system water flow to provide boiler supply temperature between 140 degrees F (60.0 degrees C) to 180 degrees F (82.2 degrees C) with a 20 degree F (11 degree C) maximum temperature drop between primary loop supply and return piping for non-condensing boilers, or design delivery water temperature for condensing boilers.

E. System Treatment: Install _________________________ (Choose one of the following: Formula 10�, or Infloor System Treatment.)
