2.01 MATERIALS |
| |
| |
A. Infloor High Capacity components: Furnish and install snowmelt distribution
manifolds that include 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
Infloor Sales & Service Center.
|
| |
| |
B. Infloor tubing: Radiant tubing shall be _______________ (Choose one of the
following: Infloor barrier cross-linked polyethylene [BPEX], orInfloor cross-linked
polyethylene [PEX]. Tubing to be furnished by Infloor Sales & Service
Center and is to
be installed in complete accord to manufacturer's instructions.
|
| |
| |
|
1. Infloor barrier cross-linked polyethylene (BPEX) as provided: nominal 3/4" (inch) [19 mm] inside diameter with an nominal 1" (inch) [25 mm]
outside diameter with a wall thickness of 0.118 " (inch) [3 mm], rated for 100 psig
(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).
|
| |
| |
|
2. Infloor cross-linked polyethylene (PEX) as provided: nominal 3/4" (inch) [19 mm] inside diameter with an nominal 1" (inch) [25 mm]
outside diameter with a wall thickness of 0.118 " (inch) [3 mm], rated for 100 psig
(689.5 kPa) at 180 degrees F (82.2 degrees C).
|
| |
| |
C. Primary boiler loop, circulating pump, snowmelt and system controls: Primary
circulating loop and controls 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 and up to 130 degrees F (54.4 degrees
C) to the snowmelt distribution manifolds.
|
| |
| |
D. System Treatment: Install Infloor system treatment, a borate-nitrite corrosion
inhibitor in concentration of 1400 ppm (one [1] quart {0.95 liter} treatment per
twenty-five [25] gallons {95 liters}water) as provided. Snowmelt applications require the addition of propylene glycol for freeze protection.
Consult propylene glycol supplier's information for proper concentration for local conditions.
