System Startup
Important! Before starting up the system,
make sure the system temperature settings
are correct. If extremely hot water circulates
through the loops, it may damage the
flooring. This is especially important with
hardwood or engineered hardwood floors.
Determine the following settings before
commencing the startup sequence.
Boiler Setpoint
1. Determine the temperature setting. The radiant
system design will calculate the supply water
temperature. For design assistance, contact
Uponor Design Services at:

Canada: 888.994.7726
2. On the boiler control, select the application icon
that offers the temperature range for the designed
supply water temperature.
3. Refer to Section 10: Boiler Control Settings
for additional information.
Warning: Do not set boiler setpoint
temperature above 185°F (85°C).
Pump Setting
To determine the pump operating speed, use flow
and pressure-loss data from the radiant design
or complete a pressure-loss calculation. Use the
calculated pressure-loss data in the Pump Curve chart
(see Figure 7-1) to select the proper pump speed.
If no pressure-loss calculation is available, use loop
lengths to gain a rough estimate. For assistance, refer
to the Uponor Complete Design Assistance Manual
(CDAM) or contact Uponor Design Services at:

Startup Sequence
1. Make sure all fittings are tightened down.
2. Check all wiring.
3. Ensure all loops are open and the drain hose from
the T&P relief valve is routed into a bucket or drain.
4. Turn on the unit (flip the switch or breaker).
5. Turn the temperature setting on the boiler down
to minimum (85°F/29°C). See Section 9: Boiler
Control Settings.
