Step 6. If electrical power has not been provided to the unit’s junction
box receptacle - Route a 3-wire, 120Vac power line to the unit’s junction
box. Remove the receptacle by removing the two securing screws. Con-
nect the supply wires to the receptacle as shown in Figure 4. Reinstall
the receptacle.
Step 7. Reinstall all removed components in reverse order of Step 5.
Reconnect the gas flex line, if it was disconnected for blower installation.
Check any gas connections that were broken for leakage.
IMPORTANT: Ground lead must be connected to the green screw
located on the junction box. Failure to do so will prevent the ap-
pliance from operating. The appliance must be electrically grounded
in accordance with local codes or, in the absence of local codes, the
National Electrical Code, ANSI/NFPA 70-(latest edition). (In Canada,
the current CSA C22-1 Canadian Electrical Code.)
