Page 3: General Safety
GENERAL SAFETY To 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. -

COLD WATER START 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. -
Page 5: Operation
1. CALL FOR HEAT LED on PCB illuminates GREEN. 2. START UP MODE LED on PCB illuminates YEL- LOW. Before 7 minutes it should go out if boiler inlet temperature is approaching the set point tem- perature. - Page 6 NOTE: The minimum return water temperature to the heater to prevent condensate is 105°F on stan- dard heaters and 120°F on 87% Efficiency heaters. Ensure that during operation the Set Point Pot is adjusted properly. Cold Start Sequence of Operation 1) 120VAC to heater sends 120VAC to Cold Start control on terminal block 1.

Page 12: Before Starting
Injection Pump Cover Installation Before Starting 1) Turn off power to the unit at the circuit breaker. 2) Turn off gas supply. 3) Shut off the water supply to the heater and, if nec- essary, drain water from the system. 4) Allow heater to cool down before attempting work. - Page 13 Fig 15: Reposition the pump body so that the electrical box points downward 3. Insert and tighten all eight (8) wrench bolts, secur- ing the pump body in place. 4. You will now be able to install the pump cover. See Fig.
