WIRING
Follow the wiring instructions furnished by the appli-
ance manufacturer, if available, or use the general instruc-
tions provided below. Where these instructions differ from
the appliance manufacturer, follow the appliance manufac-
turer instructions.
All wiring must comply with applicable electrical codes
and ordinances.
Disconnect power supply before making wiring connec-
tions to prevent electrical shock or equipment damage.
1. Check the power supply rating on the gas control and
make sure it matches the available supply. Install thermo-
stat and other controls as required.
2. For VR4204, when the gas control is installed exter-
nal to the appliance, install the conduit cover on the conduit
fitting. Do not secure conduit cover at this time.
3. Connect control circuit to gas control terminals. See
Figs. 5, 8 and 9.
NOTE: Use leadwires with insulated terminals.
4. For VR4204, make sure the conduit cover is in
position and secured to the gas valve with the screw pro-
vided. See Fig. 2.
5. Adjust thermostat heat anticipator as instructed in the
appliance manual (i.e., usually 0.1A for VR4204; 0.5A for
VR8204).
