7. 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.
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. Dial should
have the knob rotated to the 120°F mark for safety.
The circulator and boiler should start momentarily.
If not, check wiring and consult the troubleshooting
section in this manual.

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.

user's needs. This maximizes efficiency and reduces
scald potential.
