SHUTTING DOWN THE MAGNATHERM
It may sometimes be necessary to shut down the MagnaTherm. Here are the steps required to do this:
1. Switch off the main electrical disconnect switch.
2. Open the front access doors and close the main manual gas valve.
3. If freezing is anticipated, drain the MagnaTherm. (Also be sure to protect the piping in the building from
freezing.)
The steps listed above may require qualified service personnel.
RESTARTING THE MAGNATHERM
It may be necessary to restart the MagnaTherm – for example, after a power interruption. Here are the steps
required to do this:
1 Reset any errors using the user interface. See the section on “About Lockouts, Holds, and Alerts.”
2 Turn up the thermostat to call for heat.
3. In approximately 2 seconds, the blower will operate. Ignition should occur after 35-40 seconds. It may
take as long as 2-1/2 minutes.
4. If ignition does not occur, wait 5 minutes and then repeat steps 1 through 3.
5. If, after three attempts, the unit still does not light, shut down the boiler and call your service technician.
IN THE EVENT OF POWER FAILURE
The MagnaTherm will not operate during an electrical power outage. If there is an extended power outage
with danger of freezing, then the MagnaTherm (and all other water systems) should be completely drained.
Before draining the unit, turn off the gas and turn off the main power switch. When you replace the unit in
service, refer to the “Installation and Operation Manual” for instructions on filling and purging.
