10.2.2 Combustion Setup Procedure
See the detailed instructions in Section 9.10.
WARNING
Improper adjustment may lead to poor
combustion quality, increasing the amount of
carbon monoxide produced. Excessive carbon
monoxide levels may lead to personal injury or
death.
10.3 Shutting Down the MagnaTech
This step must be performed by a qualified
service person.
1. Turn off the main electrical disconnect
switch.
2. Close all manual gas valves.
3. If freezing is anticipated, drain the
MagnaTech and be sure to also protect
the building piping from freezing. All water
must be removed from the heat exchanger
or damage from freezing may occur.
10.4 Restarting the MagnaTech
If the system has been drained, see Section
10.1 for instructions on proper filling and
purging.
1. Turn off the main electrical disconnect
switch.
WARNING
Do not use this appliance if any part has
been under water. Immediately call a qualified
service technician to inspect the appliance
and to replace any part of the control system
and any gas control that may have been
under water.
10.2 Initial Operation
The initial setup must be checked before the
unit is put into operation. Problems such as
failure to start, rough ignition, strong exhaust
odors, etc. can be due to improper setup.
Damage to the boiler resulting from improper
setup is not covered by the limited warranty.
10.2.1 Initial Burner Operation
1. Using this manual, make sure the
installation is complete and in full
compliance with the instructions and all

filled with water and all air has been bled
from both. Open all valves.
3. Observe all warnings on the Operating
Instructions label and turn on gas and
electrical power to the unit.
4. The MagnaTech will enter the start
sequence. The blower and pump will
energize for pre-purge, then the ignition
sequence will start. After all safety
devices are verified, the gas valve will
open. If ignition doesn’t occur, turn off the
MagnaTech. Check that there is proper
supply of gas. Wait five minutes and start
the unit again.
5. If ignition starts normally, leave the
MagnaTech turned on.
6. After placing the unit in operation, the
Burner Safety Shutoff Device must be
tested:
(a) Close the gas shutoff valve with the
burner operating.
(b) The flame will go out, and the blower
will continue to run for the post purge
cycle. A few additional attempts to
