Note
The SFT 199 maximum water temperature is 149°F (65°C ). Ensure that this is hot enough to
meet the heating requirements of the space being heated.
If piped correctly, DHW takes priority over space heating. When the appliance detects reduced water
temperature (that is, a call for DHW), the system will reduce the fan speed.
