SECTION IV: INSTALLATION
WATER (POTABLE) HEATING AND SPACE HEATING CONNECTIONS
If this heater is used for water (potable) heating and space heating, the following
requirements apply:
- Piping and components to the water heater for the space heating application must be
suitable for use with potable water.
- Toxic chemicals, such as used for boiler treatment, shall not be introduced into the
potable water used for space heating.
- A water heater which will be used to supply potable water shall not be connected to
any heating system or component(s) previously used with a non-potable water heating
appliance.
- If the space heating requires water at a temperature higher than required for other uses,
a tempering valve shall be installed to reduce the water temperature for those uses in
order to lessen scald hazard potential.
- This water heater cannot be used for space heating applications only.
- Space heating piping connections shall be made to the free Hot/Cold connections on
the water heater. Two sets of Hot/Cold connections are supplied.
A piping diagram for water (potable) heating and space heating is shown in
Figure 30.
