6) Install Extension Fitting (if applicable)
If pilot gas tube going into the valve already has an extension piece (short piece of
tubing plus 3/16” brass fitting), unscrew the shorter piece of tubing and proceed to
Step 13. Otherwise, follow these steps to install the proper fitting.
This step must be performed if a TS-11 valve was just removed.
If a Baso valve was uninstalled, cut off 2.5” of the free end of the incoming pilot gas tube
to remove the original ferrule and nut and a section of the tubing. If a TS-11 valve was
uninstalled, cut off just enough tubing to remove the ferrule.
Refer to the Assembly Drawing included in this manual:
i) Unscrew one end of the 3/16” fitting (Part 4, Assembly Drawing) to release the
nut and ferrule. Slide the nut and the ferrule onto the free end of the incoming
pilot gas tube.
ii) Insert the remaining portion of the fitting onto the end of the pilot gas tube. Screw
on the nut to firmly attach the fitting to the tube. See pictures below for details.
iii) Ensure all connections are leak-proof. Do not over-tighten.
