the thermocouple, if equipped on standing pilot
models) to the gas valve. Be careful not to kink the
aluminum tubing.

on the crossovers of the first 2 burners on the side of
manifold where valve is now mounted (Fig. 10).

models, be sure the ignition cable or sensing lead
is not pinched under the burners).
