WARNING
Fire or Explosion Hazard.
Can cause property damage, severe injury or
death.
Always change the main burner orifices when
converting from natural to LP gas or from LP to
natural gas. Follow appliance manufacturer
specifications and instructions.
CAUTION
Equipment Damage Hazard.
Improper wiring can damage equipment.
Never apply a jumper across or short the
thermostat, 24V hot or 24V common terminal in
the SV9510/SV9520 wiring harness. This can
burn out the heat anticipator in the thermostat or
damage the system transformer.
IMPORTANT
Ignition system controls with step-opening
regulators (SV9510P/SV9520P) CANNOT be
field-converted to LP or natural gas.
