Install Thermocouple or Thermopile
Push-in Design
1. Insert the thermocouple or thermopile tip into the hole
or barrel provided beneath the pilot burner. See Fig. 20
and 21.
2. Push in firmly until the thermocouple or thermopile is
locked into place.
Attachment Nut Design
1. Insert the thermocouple or thermopile tip into the hole
or barrel provided beneath the pilot burner. See Fig. 21.
2. Engage the attachment nut threads and tighten until the
thermocouple or thermopile is locked into place.

Install Bleed Gas Tubing (if used):
1. Route the bleed gas tubing from the bleed tapping on
the gas control to the pilot burner.
2. Push the clip into place as shown in Fig. 22.
3. Insert the bleed gas tubing until 3/8 inch (10 mm) of the
tubing is above the pilot burner bracket. The tip of the
bleed gas tubing must not extend into the pilot flame.
THIS DIMENSION SHOULD BE
MAXIMUM OF 3/8 INCH (10 MM)

Install Q314 “A” Mounting Bracket Adapter
To convert the mounting bracket on a Q314 from a “B”
mounting bracket to an “A” mounting bracket, install the “A”
mounting bracket adapter to the pilot burner mounting
bracket. Then install the pilot burner to the main burner. See
Fig. 16.
Change Insert Orifice (See Fig. 23)
1. Disconnect the pilot tubing from the pilot burner and
remove the insert orifice. Light force may be required to
remove the orifice.
2. Cut off the old compression fitting.
NOTE:
When replacing an orifice, cut off the old
compression fitting and replace with a new
compression fitting. Never use an old
compression fitting because it may not provide
a gas-tight seal. See Fig. 19.
3. Square off the end of the pilot tubing and remove all the
burrs.
4. Insert the new compression nut over the pilot tubing
and slide out of the way.
5. Insert the new orifice into the pilot burner and push the
pilot tubing into the pilot burner until it bottoms.
6. While holding the tubing all the way in, slide the
compression fitting into place and engage the threads.
Turn until finger tight.
7. Using a wrench, tighten the compression fitting one turn
beyond finger tight.
