Tee fitting for vertical hot water supply lines Combination Potable and Space Heating Application Tee fitting must be installed as shown. This ensures that any air in the water lines will be purged through the domestic water faucets and showers. DANGER: When this system requires water for space heating at elevated temperatures (above 125°F [52°C]), a mixing or tempering valve must be installed in the hot water supply line to the house in order to reduce the scald hazard potential. DANGER: Any piping or components used in the installation of this water heater in a combination potable and space heating application must be suitable for use with drinking water. DANGER: If this water heater is installed in an application intended to supply domestic hot water needs and hot water for space heating purposes, do not connect the heater to an existing heating unit or components of a heating system that have previously been used with a non drinking water system. Toxic chemicals such as those used for boiler treatment may be present and will contaminate the drinking water supply causing possible health risks. Never introduce toxic chemicals, such as those used for boiler treatment, into this system. ! ! !
