4. Push tubing into pilot gas tapping on outlet end of
the control until it bottoms. While holding tubing all the
way in, slide fitting into place and engage threads. Turn
until finger tight. Then tighten one more turn with wrench.
Do not overtighten.

CONNECT THERMOCOUPLE (24V, 10OV, 120V, and
220/240V models)
The thermocouple connection to the power unit or
ECO connector (Figs. 6 and 7) is an electrical connection
and must be clean and dry. Never use pipe compound.
Tighten only 1/4 turn beyond finger tight to give good
electrical continuity.
CONNECT ECO (Standard capacity 24V, 10OV, 120V,
and 220/240 models)
If the
ECO is provided, the leadwires must be
equipped with insulated 1/4 in. female quick-connect ter-
minals. Leadwire lengths must not exceed the lengths
shown in Tables 5 and 6. Connect the high-limit or ECO
Ieadwires to the two terminals on the ECO
If ECO is not provided, connect a
Q313B thermopile
generator in place of the thermocouple to act as the high-
Iimit for the system.
