This is not necessary on systems utilizing a zone valve to control the BoilerMate® temperature. 4. After completing the boiler piping, slowly open the boiler fill valve and pressurize the BoilerMate® loop. Check for leaks and repair as necessary. Proceed to the appropriate wiring section in this manual. If installing on city water supply a properly sized THERM-X-TROL® is required with the BoilerMate® and should be installed as set forth in the THERM-X-TROL® product installation manual.

READY-TO-RUN RTR-SERIES PIPING INSTALLATION DOMESTIC WATER PIPING BOILER PIPING 1. Connect the cold water supply to the pipe labeled COLD WATER. 2. Connect the HOT WATER piping to the domestic hot water system. 3. Make an 8-inch “heat trap” on the HOT WATER outlet as shown in the diagram. This will reduce standby losses from heat migrating up the piping. 4. When all domestic water piping is complete, open the cold water supply and allow some water to enter the tank. Look and listen for signs of leaks and repair as necessary before continuing. Note: If installing on a city supply, ensure a dedicated Thermal Expansion tank (Therm-X-Trol® or equivalent) is used. 5. Install a blowdown tube on the T&P relief valve outlet. Plumb to within 6 inches above a floor drain or as directed by plumbing code. 1. Plumb the BOILER SUPPLY line. The circulator and flow check are factory installed 2. Pipe the BOILER RETURN connection to the boiler return line. Be sure the return line is NOT plumbed to the suction side of any heating circulators. This may require moving the heating circulator off the boiler tapping on packaged boilers. Failure to do so will result in overheating and tank damage when the heating system is in operation. 3. After completing the boiler piping, slowly open the boiler fill valve and pressurize the heat exchanger loop. Check for leaks and repair as necessary. Proceed to the appropriate wiring section in this manual. If installing on city water supply a properly sized THERM-X-TROL® is required with the BoilerMate® and should be installed as set forth in the THERM-X-TROL® product installation manual.

WHS PREMIER SERIES PIPING INSTALLATION DOMESTIC WATER PIPING 1. Thread the included brass tee onto the pipe marked COLD WATER. 2. Screw the drain valve into the opposite end of the brass tee 3. Connect the cold water supply to the remaining port on the brass tee 4. Thread the included T&P Safety Relief Valve into the offset 3/4” port on the top plate. Install a blowdown tube to within 6 inches of a floor drain or as directed by plumbing code. 5. Connect the center hot water outlet port on the top plate to the domestic hot water system. 6. Make an 8-inch “heat trap” as shown in the diagram. This will reduce standby losses from heat migrating up the piping. 7. When all domestic water piping is complete, open the cold water supply and allow some water to enter the tank. Look and listen for signs of leaks and repair as necessary before continuing. Note: If installing on a city supply, ensure a dedicated Thermal Expansion tank (Therm-X-Trol® or equivalent) is used. BOILER PIPING 1. Plumb the circulator or zone valve on the BOILER SUPPLY line. If using a separate circulator, the pump flange can be mounted directly to the threaded pipe marked BOILER SUPPLY. Alternately, the circulator can be placed anywhere on the boiler supply line. 2. Pipe the BOILER RETURN connection to the boiler return line. Be sure the return line is NOT plumbed to the suction side of any heating circulators. This may require moving the heating circulator off the boiler tapping on packaged boilers. Failure to do so will result in overheating and tank damage when the heating system is in operation. 3. Install a weighted flow check on the boiler return line. This is not necessary on systems utilizing a zone valve to control the BoilerMate® temperature. 4. After completing the boiler piping, slowly open the boiler fill valve and pressurize the BoilerMate® loop. Check for leaks and repair as necessary. Proceed to the appropriate wiring section in this manual.
