Verifying Ground Connections:
Use a multimeter
to verify that fireplace metal surfaces are properly
grounded using the following procedure:
1. With the multimeter set to read Ohms on the
lowest range, short the probes together and
verify a reference reading for “0 Ohms” (or a
very low value) as shown in Figure 18.
2. Connect the multimeter between the copper
grounding bar and the green wire connection on
the fireplace’s AC input screw terminal as shown
in Figures 19a and 19b. Verify that the reading
is 0 Ohms (within 0.1 Ohms of the reference
value previously noted).
