15. Reconnect the thermostat leads, the sensing probe lead, and the high
voltage cable according to the labels on the wires. Do not connect
the electrical supply at this time.
a. On grounded versions (part numbers ending with the
letters H, L, G, or J
[e.g., G60QBG or G60QBJ]), connect the
black lead wire to one of the ground terminals on the ignition
control. Four ground spade terminals are located just below the
terminal board on terminal board models (see Figure 2) or in a
square arrangement on the end of the plug-in Heyco models
(see Figure 3).
On ungrounded versions (part numbers ending with a K
[e.g., G60QBK]), connect the black lead wire to Terminal 5 on
the ignition control.
On systems using G600 ignition controls, connect the black lead
wire to a ground terminal on the ignition control.
b. Connect the blue lead wire to Terminal 1 on the ignition control.
IMPORTANT: To permit verification of pilot operation, do not connect
the red lead wire to any terminal at this time.
16. Check for leakage.
a. Open the pressure connection between the manual shutoff valve
and the VLV valve.
b. Connect air tubing with a maximum pressure of 1-1/2 times the
valve’s maximum operating pressure (as indicated on the valve)
to the opened pressure connection.
c. Paint all valve body connections with a rich soap and water
solution.
If bubbles occur, this is an indication of a leak. To stop a leak,
tighten joints and connections. Replace the part if the leak
cannot be stopped.
If bubbles do not occur, remove the air tubing and close the
pressure connection.
