Connect Pilot Gas Tubing
1. Cut tubing to desired length and bend as necessary
for routing to pilot burner. Do not make sharp bends or
deform the tubing. Do not bend tubing at gas control or
pilot burner after compression fitting has been tightened,
as this may result in gas leakage at the connection.
2. Square off and remove burrs from end of tubing.
3. Unscrew compression fitting from the pilot outlet
(Fig. 2). Slip the compression fitting over the tubing and
slide out of the way.
NOTE: When replacing a gas control, cut off old compres-
sion fitting and replace with the new compression
fitting provided on the gas control. Never use the old
compression fitting as it may not provide a gas-tight
seal.
4. Push tubing into the pilot gas tapping on the outlet
end of the control until it bottoms. While holding tubing all
the way in, slide compression fitting into place and engage
threads—turn until finger tight. Then tighten one more
turn with wrench. Do not overtighten. Refer to Fig. 9.
5. Connect the other end of tubing to pilot burner
according to pilot burner manufacturer instructions.

5. Remove seals over gas control inlet and outlet if
necessary.
6. Connect pipe to gas control inlet and outlet. Use
wrench on the square ends of the gas control. If an adapter
is used, place wrench on adapter rather than on gas control.
Refer to Figs. 2, 3 and 8.
Install Thermocouple
The Q340A Thermocouple (with adapters) is pro-
vided with SUPER TRADELINE models of the
VR8200A. Install the Q340A as follows:
1. Determine if the pilot burner requires a thermo-
couple with a push-in clip or attachment nut, and attach the
correct adapter to the Q340.
2. a. For push-in clip type pilot burners: From beneath,
insert the tip of the Q340 into the hole or barrel of the
pilot burner. Push in firmly to lock in place.
b. For attachment nut type pilot burners: From be-
neath, insert the tip of the Q340 into the hole or
barrel in the pilot burner. Engage the threads of the
attachment nut and tighten securely.
