8.2 Functional Trouble Shooting Procedures
The verification of proper operation of your Surefire 512 can be performed
using Procedure #1 or Procedure #2 described below.
Procedure #1
is recommended if the unit is connected to your wood pellet
stove or Coal stoker.
Procedure #2
is recommended if the Surefire 512 has been disconnected
from your wood pellet stove or stoker.
8.21 Procedure #1 - Surefire 512 connected to stove / heater
Make sure that the hookup connections in Section 5 have been made.
Then, with the stove/heater in operation (a fire in the box) and the fans of
the stove/heater turning, unplug the ac input cord to the Surefire 512. The
stove/heater should continue to function normally.
1. If the stove / heater fans intermittently turns on and off more than a few
times, it is a sign that either the battery is near the end of its discharge
or that a battery connection is loose. Tighten battery connections
if they are loose and plug the ac input cord back into the wall socket
and give the Surefire 512 a few hours to recharge the battery. If battery
connections were tight, change the battery.
2. If the fans in the stove / heater are off and remain so, make sure the on/
off rocker switch on the Surefire 512 is in the "on" position. If there is no
change, continue with the steps below.
