7.2 Installation Test
Energize the stove. After allowing it about 15 minutes to heat up, extract
the Surefire 512's power cord from the AC wall receptacle to simulate power
failure. The stove should continue to operate normally. The fan on the
Surefire 512 should be turning and free of air blockage.
In certain pellet stove models, when blowers are operated at very low speed
there may be small discernible differences in fan motor speeds between
modes when the AC cord is plugged into the wall and when there is back
up operation.
Plug the AC power cord back into the wall outlet (or turn switch controlling
wall outlet back on if it has been turned off instead of pulling the plug
above). The stove should continue to operate. Check to see if the internal
fan of the Surefire 512 has stopped. This is normal and indicates that the
Surefire 512 has recognized the return of AC. It is now out of the "battery
back up" mode and has returned to its normal state of charging the battery.
Once properly connected, the Surefire 512 system requires no
maintenance.
When AC power disappears, it will automatically convert
battery power to AC power for stove or Coal stoker operation. It will
automatically replenish the battery when AC power returns. During all of
these times and power transitions, the Surefire 512 leaves the supply of
power to the heating appliance completely uninterrupted and requires no
manual adjustments.
7.3 Changing the battery.
If for any reason the battery needs changing, it is important to follow the
steps below in the order shown to avoid possible damage to the Surefire 512.
Step 1
Turn the on/off rocker switch of the Surefire 512 to the off position.
Step 2
Unplug the input power cord of the Surefire 512 from the wall outlet.
Step 3
Unplug the input power cord of the stove / heater from the AC outlet of the
Surefire 512.
