C. DOMESTIC WATER PIPING
Domestic water connections must be installed in accordance with all local and national plumbing codes or
any applicable prevailing standards. The appliance is supplied with a rated mixing valve certified to ASSE
1017. You must completely follow the instructions included with the mixing valve for proper installation.
This mixing valve must be installed on the domestic outlet to assure that hot water temperature does not
vary more than +/– 5°F, as the unit adjusts its stored water automatic set point to meet the requirements
of the hydronic heating module. The valve MUST NOT be allowed to freeze. If the mixing valve is
installed in a potentially freezing situation, suitable insulation must be fitted to prevent damage. DO NOT
use excess thread sealant (in liquid, tape or other form) as this may cause the mixing valve to fail. Toxic
chemicals shall not be introduced into the mixing valve system.
Recommend to the user that the mixing valve be checked annually to ensure its continued
function.
D. HEATER PIPING
The domestic inlet and outlet ports on the heater are 1” NPT connections. We recommend the installation
of shut-off valves and unions on both the inlet and outlet ports to isolate the appliance for future service.
It is important that the connections on the inlet and outlet are brass or copper. Never use dielectric unions
or galvanized steel fittings. Teflon thread sealant must be used to seal all tank connections. An approved
ASSE 1017 mixing valve is provided with every appliance and must be installed on the outlet to protect
the user from scalding temperatures. This valve reduces the point of discharge temperature by mixing the
hot and cold water from the discharge outlet or mixed outlet port. This device alone will not protect the
user from scalding temperature. To install and set up the mixing valve, follow the pre-installation steps in
this manual and also follow the enclosed instructions included with the mixing valve.
E. MIXING VALVE INSTALLATION
The mixing valve provided with this appliance must be installed on the hot water outlet connection to
reduce the risk of scalding. This mixing valve only reduces the risk of scalding injury.
1. All installations must be carried out by licensed
professionals.
2. The installer must ensure compatibility of all
installations. Example: Temperature of hot water
– marked “H”, cold water inlet – marked “C”, and
mixed outlet – marked with directional arrow.
3. The mixing valve may be installed in any
position.
