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 feet.

2. Toxic chemicals, such as those used for boiler treatment,

must not

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 the suggested piping arrangement.
