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 means, such as an ASSE approved mixing
valve must be installed to temper the water for those uses in order to
reduce the scald hazard potential.
