VR8245 AND VR8345 UNIVERSAL ELECTRONIC IGNITION GAS CONTROLS

69-2013

Fig. 3. Top view of gas control.

Fig. 4. Proper use of wrench on gas control.

Connect Pilot Gas Tubing (Intermittent

Pilot Ignition Only)

Remove the pilot gas seal (plug).

Cut tubing to desired length and bend as necessary
for routing to pilot burner.

CAUTION

Do not kink tubing.

1. Do not make sharp bends or deform the tubing.
2. Do not bend tubing at the gas control or pilot

burner after compression fitting has been
tightened because this can result in gas
leakage at the connection.

Square off and remove burrs from end of tubing.

Use the compression fitting supplied with this gas
control. Slip the fitting over the tubing and slide out
of the way.

NOTE: When replacing a gas control, cut off old com-

pression fitting and replace with the new com-
pression fitting provided on the gas control.
Never use the old compression fitting because it
may not provide a gas-tight seal.

Push tubing into the pilot gas tapping on the outlet
end of the control until it bottoms. While holding tub-
ing all the way in, slide compression fitting into
place, engage threads and turn until finger tight.
Then tighten one more turn with wrench. Do not
overtighten. Refer to Fig. 5 and 6.

Connect other end of tubing to pilot burner accord-
ing to pilot burner manufacturer instructions.

Fig. 5. Always use new compression fitting.

Fig. 6. Remove pilot gas seal (plug) and install pilot

gas tube for intermittent pilot application on VR8345.
