Recommended Grounding Practices
Use an Earth ground or a signal ground as described below.
Earth ground (Base, Rectification Flame Amp
Module, other modules optional)
1. Use to provide a connection between the base and the
control panel of the equipment. Earth ground must be capable
of conducting enough current to blow the breaker in the event
of an internal short circuit.
2. Use wide straps or brackets to provide minimum length,
maximum surface area ground conductors. If a leadwire is
required, use 14 AWG copper wire.
3.
Make sure that mechanically tightened joints along the ground
path are free of nonconductive coatings and protected against
corrosion on mating surfaces.
Signal ground
Note the 18V system ground is not electrically connected to earth
ground. Follow local codes and appliance recommendations to
determine if this should be connected to earth ground.
