INSTALLATIONS SUITABLE FOR WATER (POTABLE) HEATING AND
SPACE HEATING.
Instructions are as follows:
1. All piping components connected to this water heater for space
heating applications must be suitable for use with potable water. In
Massachusetts, space heating piping length must not exceed 50 feet.
2. Toxic chemicals, such as those used for boiler treatment, must not
be introduced into potable water used for space heating.
3. This water heater must not be connected to an existing heating system
or component(s) previously used with a non-potable water heating
appliance.
4. When the system requires water for space heating at temperatures
higher than required for other uses, a means such as an ASSE approved
mixing valve shall be installed to temper the water for those uses in order
to reduce scald hazard potential.
Please refer to the illustration below for suggested piping arrangement.
