Improper configuration can cause fuel buildup and
explosion. Improper user operation may result in
property loss, severe physical injury, or death.
Any changes to safety-related configuration
parameters must only be done by experienced and/
or licensed burner/boiler operators and mechanics.
If any odor of gas is detected, or if the gas burner
does not appear to be functioning in a normal
manner,
close the main gas shutoff valve
. Do not
shut off the power switch. Contact your heating
contractor, gas company, or factory representative.
The MagnaTherm Appliance is protected against over-
