HEATING

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 shall be installed to temper the water for those uses in order to reduce the scald hazard potential.

Please refer to the illustration for suggested piping arrangements.
