1. Shutting down the MagnaTherm
It may sometimes be necessary to shut down the MagnaTherm.
Here are the steps required to do this:
1. Disconnect Power at the main electrical disconnect switch.
2. Shut the main manual gas valve located at the back of the
unit. It has a yellow handle
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.
2. 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. See the Section 12 "Troubleshooting" of the Installation and Operating Manual.
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 unit and call your service technician.
