THE FOLLOWING INSTRUCTIONS ARE FOR INSTALLATION
OF: GAS WATER HEATERS SUITABLE FOR WATER
(POTABLE) HEATING AND SPACE 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 ft.
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, 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 Figure 12 and Figure 13 for suggested piping arrangements.
