Water Piping
Indirect Water tank and floor Heating Installation
This procedure is provided for illustrative purposes and should be used for reference only. When installing the hydronic piping system, ad-
here to specifications, drawings, and details provided by the system designer. See Figure 19 below.
1. When selecting an indirect water storage tank, ALWAYS use an INDIRECT type tank where the Hydro Kit water circuit is isolated from the
domestic water system.
2. Use the pump (see (1) on diagram) with sufficient capacity to assure correct water pressure and to supply water to the Hydro Kit.
3. Install the shut-off valve (see (2) on diagram) on both sides of the pump to allow for cleaning and repair of the pump.
4. Install the flexible connectors (see (3) on diagram) to minimize noise and vibration transferred from the pump.
5. Optionally, install the pressure gauge (see (4) on diagram) to monitor the piping system water pressure.
6. Install the expansion tank (see (5) on diagram) to accommodate changes in system water pressure due to temperature difference.
7. When installing the indirect water tank, insert the water tank temperature sensor provided with the Hydro Kit.
