THE RECOMMENDED CONFIGURATION
The Surere 512 and its associated battery bank should be near to one
another. However liquid batteries should not be located in living quarters
or near sources of heat e.g. the pellet stove. Ideally the back up system with
its associated battery should be installed in a dry garage, crawl space or
basement. The 120 VAC utility power should be transmitted to the pellet
stove through electrical cabling or extension cords which are deemed
appropriate by the regional electrical code. Other recommendations for the
installation location are listed in section 6.2 of this manual.

2 Introduction
The Surere 512 Stove Sentry is an innovative power station specically
designed to operate wood pellet stoves and coal stoker heaters. When
properly installed, it will provide the user many years of service, and will
render the user's heating appliance immune to power failures. To ensure
that the Surere 512 is optimally used and properly connected, the user
should take time to read this instruction manual and follow its directions.
Read this manual thoroughly. Failure to follow its instructions can lead to
serious injury.
Here Is How It Works
The Surere 512 interfaces between a wood pellet stove or coal stoker and
the AC electrical supply.
When electricity is present, the Surere 512 charges a battery and surveys
the power line. At the instant that a power failure occurs, the Surere 512
converts the energy stored in the battery to AC power.This assures operation
of the pellet stove or Coal stoker without interruption, during the absence
of electricity.
When AC utility power is restored, the Surere 512 reinstates AC utility
power as the prime energy source to operate the pellet stove or coal
stoker. Simultaneously and automatically, the Surere 512 commences the
recharging of the battery, to return it to full capacity in preparation for the
next power failure.
3 Inspection
Upon removal of the Surere 512 from its packaging, the user should
examine it for any signs of physical damage sustained in shipment. If
damage has occurred, it should be returned to vendor for replacement.
4 Applications
The Surere 512 is designed to operate certain models of wood pellet or
coal stoker stoves. User should verify that the electrical power consumption
of the heating appliance intended for connection to the SF 512 is rated
less than 450 Watts continuous. Should it exceed 450 Watts, the SF 512 is
unsuitable for the application.

5 Battery Considerations
Battery Selection
Given a xed output power requirement, the operating time that the
Surere 512 will provide in the absence of electricity, is determined only by
the size and condition of the battery. It is important for the user to select
a deep cycle, sealed, and maintenance free type, such as a marine battery.
Automotive batteries are unsuitable and therefore not recommended.
The condition of a battery is determined by its ability to attain and maintain
a 100% state of charge. In order to measure the state of charge the user
should use a digital voltmeter that can display hundredths of a volt when
measuring 12 Volts. The user should measure battery voltage at the battery
posts, with the battery disconnected. For deep cycle batteries, the following
table relates the State of Charge to Battery Voltage.
6 Installation
6.1 Items Required
Tools: Philips screw driver, Small slip-joint pliers
Battery: The user should select a battery with wing nut connections if
possible. (If the user wishes to use a battery with conventional posts, he
should install wing nut adapters.)
6.2 Location
The Surere 512 can be mounted vertically or horizontally on a at smooth
surface - wall or oor location
A) Close to 3-prong AC outlet - within 5 feet.
State of Charge Battery Voltage
100% 12.7-12.9
80% 12.5-12.6
60% 12.3-12.4
40% 12.1-12.2
20% 11.9-12.0

Page 4
B) Dry - In a location where no liquids, (water or other chemicals) can drip
or splash onto the unit.
C) Safe- Do not install the Surere 512 in the same compartment as batteries
or any ammable liquids such as gasoline or kerosene. (Some batteries,
while being charged, can emit small amounts of hydrogen gas requiring
the battery to have some ventilation.)
D) Ventilated - Do not block either the fan or the exit air ports of the
Surere 512. For example, do not mount the unit to a carpeted oor or
wall, the carpet bers will block air leaving their exit ports. The mounting
surface should be at and smooth. Do not place objects on top of the unit.
Allow at least 2 inches of air clearance for both the sides and top of the
unit. Any compartment containing the Surere 512 system must have some
ventilation - it should not be airtight.
E) Close to battery - The Surere 512 comes with battery cables that are
four feet in length. Do not use additional wire to increase this distance. It is
recommended that the battery be in its own box and at least 2 feet from the
Surere 512 in a space that has some ventilation.
F) Cool - Room air temperature should be between 30 and 105 degrees F.
(0 to 40 degrees Centigrade).
Caution! Do not block or obstruct either the fan or the exit air ports of
the unit. Do not place objects on top or against the unit. Overheating
and damage to the unit may result.
Warning! The Surere 512 has several components with electrical
contacts that switch electrical currents. Opening or closing any of these
electrical contacts can produce a spark that could ignite an explosive
air mixture. To prevent re or explosion, do not install the Surere 512
in a compartment that contains a ammable liquid such as gasoline or
in the same box as a battery -which under some conditions can emit
small quantities of hydrogen gas.
6.3 Mounting
Attach the Surere 512 to a at surface using four #10 screws or bolts. The
ange on the bottom of unit has cutouts for the screws / bolts.

7 Connections (See Above)
7.1 Initial hookup procedure
After having properly secured the Surere 512 to its mounting surface,
follow the procedure below to connect the unit to the stove / heater and to
the battery.
Step 1
Turn the on/o rocker switch to the o position.
Step 2
Connect the battery cables to the battery. The red cable must be connected to
the positive (+) terminal of the battery. The black cable must be connected to
the negative (-) terminal of the battery. Do not reverse! A reverse connection
will cause fuses (factory replaceable only) inside the unit to blow and possibly
cause other damage. A reversal also voids your warranty.
Step 3
Connect the stove / heater to the Surere 512 by plugging the input ac
power cord of the stove / heater into the AC outlet of the Surere 512.
Step 4
Plug the AC input power cord of the Surere 512 into an ordinary 120 VAC
wall outlet. If the wall outlet is controlled by a switch then the switch should
be turned on.
Step 5
Turn the on/o rocker switch of the Surere 512 to the "on" position unless
it is summer time and the stove is not in use.

Page 6
7.2 Installation Test
Energize the stove. After allowing it about 15 minutes to heat up, extract
the Surere 512's power cord from the AC wall receptacle to simulate power
failure. The stove should continue to operate normally. The fan on the
Surere 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 dierences 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 o instead of pulling the plug
above). The stove should continue to operate. Check to see if the internal
fan of the Surere 512 has stopped. This is normal and indicates that the
Surere 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 Surere 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 Surere 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 Surere 512.
Step 1
Turn the on/o rocker switch of the Surere 512 to the o position.
Step 2
Unplug the input power cord of the Surere 512 from the wall outlet.
Step 3
Unplug the input power cord of the stove / heater from the AC outlet of the
Surere 512.

Page 7
Step 4
Disconnect the battery cables. Caution: Make sure that step 2 has been
done prior to disconnecting the cables.
Step 5
Replace battery. To reconnect the Surere 512, follow steps 1 thru 6 of 6.1
the initial wiring hookup procedure.
8 Trouble Shooting Guide
8.1 Symptoms and suspected causes are listed below.
Symptom #1
Stove/heater does not run when AC is present.
Suspected Causes:
• Stove control turned o.
• Thermostat setting below room temperature.
• Input ac cord to stove not connected to AC outlet of Surere 512.
• Input cord of Surere 512 not connected to AC outlet in wall.

8.2 Functional Trouble Shooting Procedures
The verication of proper operation of your Surere 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 Surere 512 has been disconnected
from your wood pellet stove or stoker.
8.21 Procedure #1 - Surere 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 re in the box) and the fans of
the stove/heater turning, unplug the ac input cord to the Surere 512. The
stove/heater should continue to function normally.
1. If the stove / heater fans intermittently turns on and o 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 Surere 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 o and remain so, make sure the on/
o rocker switch on the Surere 512 is in the "on" position. If there is no
change, continue with the steps below.

Page 9
3. Turn thermostat for stove/heater up a few degrees to ensure that the
stove controls did not shut down the stove at about the same time the
AC cord was unplugged.
If the fan on the Surere 512 is not turning, then perform the following steps:
1. Check the battery connections.
2. Check the battery voltage with a voltmeter. If battery voltage is less
than 11 volts, the battery is dead. If the battery reads 12 Volts or more,
the Surere 512 may be defective.
8.22 Procedure #2.
This procedure is performed on a work bench. Perform the steps below in
order given.
Step 1.
1. Place the on/o rocker switch of the Surere 512 into the o position.
2. Unplug the Surere input power cord from the AC wall socket.
3. Unplug the stove / heater from the Surere 512.
4. Disconnect the battery cables then move the Surere 512 to a workbench.
Step 2.
At the workbench, make sure that no connections to the Surere 512 have
been made. If so then remove connections.
Step 3.
Connect the battery cables to the battery making sure that the ring terminals
do not touch each other. (Red cable to the positive(+) battery terminal and
the black cable to the (-) terminal).
Step 4.
Plug an AC line cord of ordinary lamp with a 100 watt bulb or less into a 120
VAC wall socket. Turn on the lamp.
Step 5.
Leave the lamp switch on. Unplug the lamp and plug the ac line cord of the
Surere 512 into the same wall outlet. Then plug the lamp cord into the AC
outlet of the Surere 512. The lamp should turn on. If the lamp does not turn
on then the Surere 512 is defective. If the lamp does turn on then leave the
lamp switch in the "on" position and proceed to step 6.

Page 10
Step 6.
With the lamp on, turn the on/o switch of the Surere 512 to the on
position. Unplug the Surere 512 from the wall socket but leave the lamp
plugged into the Surere 512. If the lamp stays on then the Surere 512 is
functioning normally and is in the battery back up mode. If the lamp goes
o then either the battery is dead or the Surere 512 is defective.
Step 7.
If the lamp went o, ensure that the battery cables are well and properly
connected. Ensure that the Surere 512 "on/o" switch is in the on position.
With a voltmeter set to read DC volts measure the battery voltage. If the
meter reads 12.5 volts or more then the Surere 512 is presumed to be
defective.
If procedure #2 above indicates that your Surere 512 has been damaged
and your unit is still under warranty then follow the steps outlined in the
warranty section. If the warranty period has expired or if the warranty has
been violated due to operator error or misuse, then call : Alternative Heating
and Supplies at [phone] or fax [phone] to receive authorization
for shipment back to distributor for an estimate and possible repair.
