GENERAL SAFETY T o meet commercial hot water use needs, the high limit safety control on this water heater is adjustable up to 210°F . However , water temperatures over 125°F can cause instant severe burns or death from scalds. When supplying general purpose hot water , the rec- ommended initial setting for the temperature control is 125°F . Saf[...]

4 COLD WA TER ST AR T Before arriving at the job site to begin the installation, it's important to first inspect the system and determine what materials you will need. Some parts are includ- ed with the controller while others you will need to provide. 1 Control Box 1 T emperature Sensor 1 V alve assembly with actuator (Shipped separately) Wir[...]

10 COLD WA TER R UN Pur pose The Cold W ater Run system utilizes a variable-speed pump to inject the proper amount of water from the main system loop into the boiler to maintain the opti- mum inlet temperature. This approach allows the full capacity of the boiler to be utilized to meet the system load, while at the same time continuously maintainin[...]
