Amtrol Top Down, WH-7 Classic Series, WH-9 Classic Series, RTR Startup Procedure for ALL Models

Page 25

11. STARTUP PROCEDURE FOR ALL MODELS

1.PURGE HEAT EXCHANGER: The heat exchanger should be free of large air pockets to allow the circulator to operate properly. Using the diagram below as a guide, isolate the boiler return line and flush the loop until large air pockets are purged. After this, the air elimination equipment will collect smaller air bubbles to maximize efficiency.

2.FILL TANK: Open the hot water fixture furthest from the heater. Open the cold water supply and allow the water to run until air stops emerging. Until all air is purged from the hot water system, air pockets may appear at any hot water fixture. This is considered normal and will clear as hot water is used.

3.START HEATER: Turn power on to the unit. Smart Control™ models come pre-set at 120°F for safety. Dial units should have the knob rotated to the 120°F mark. The circulator and boiler should start momentarily.

If not, check wiring and consult the troubleshooting section in this manual.

4.CHECK OPERATION: The BoilerMate® will begin to heat. Depending upon the size of the BoilerMate, output of the boiler and the space heating load, the unit should typically reach set temperature within 15 to 60 minutes. If heating does not occur, consult the troubleshooting section in this manual. Note: Large heaters coupled with small boilers may exceed this time period upon initial startup.

5.SET TEMPERATURE: The BoilerMate® control should be set to the minimum temperature consistent with the user’s needs. This maximizes efficiency and reduces scald potential.
