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
tubing. Do not bend tubing at control after compression nut
has been tightened, as this can result in gas leakage at
connection.
2. Square off and remove burrs from end of tubing.
3. Push tubing into compression nut clearance hole until
tubing bottoms.
NOTE: When replacing a pilot burner or orifice, cut off old
compression fitting and replace with new compression
fitting provided with new pilot burner. Never use old
compression fitting as it may not provide a gas-tight seal.
See Fig. 3.
4. While holding tubing all the way in, engage threads
and turn until finger tight.
5. Using a wrench, turn compression nut one turn beyond
finger tight. DO NOT OVERTIGHTEN.
6. Connect other end of tubing to gas control according to
gas control manufacturer instructions.

INSTALL THERMOCOUPLE OR THERMOPILE
PUSH-IN DESIGN
1. Insert thermocouple or thermopile tip into hole or
barrel provided beneath pilot burner. See Fig. 4.
2. Push in firmly until thermocouple or thermopile is
locked into place.
ATTACHMENT NUT DESIGN
1. Insert thermocouple or thermopile tip into hole or
barrel provided beneath pilot burner. See Figs. 4 and 5.
2. Engage attachment nut threads and tighten until ther-
mocouple or thermopile is locked into place.

INSTALL BLEED GAS TUBING (if used):
1. Route bleed gas tubing from bleed tapping on gas
control to the pilot burner.
2. Push clip into place. See Fig. 6.
3. Insert bleed gas tubing until 3/8 inch [10 mm] of tubing
is above pilot burner bracket. Tip of bleed gas tubing must not
extend into pilot flame.
INSTALL “A” MOUNTING BRACKET ADAPTER
(optional)
To convert mounting bracket from “B” mounting bracket
to “A” mounting bracket, install the “A” mounting bracket
adapter to the pilot burner mounting bracket. Then install
pilot burner to main burner.
