Install the mixer module
1. Put the mixer module in the gas connect console.
2. Connect the mixer module-bracket assembly to the manifold:
a. Use a 5 mm, hexagonal-key wrench to install the 2 cap screws that attach the bracket to
the manifold. Do not fully tighten the screws.
b. Use a 4 mm, hexagonal-key wrench to install the 3 cap screws that attach the mixer
module to the bracket. Do not fully tighten the screws.
3. Put the mixer module and bracket on the manifold. Adjust the mixer module and bracket as
necessary for good alignment.
4. Tighten the following screws to 2.3 N·m (20 in∙lbf):
a. Use a 5 mm, hexagonal-key wrench to tighten the 2 cap screws that attach the bracket to
the manifold.
b. Use a 4 mm, hexagonal-key wrench to tighten the 3 cap screws that attach the mixer
module to the bracket.

If the 3 screws on top are tightened first, the seal between the 2 manifolds
can be bad. Make sure to tighten the 2 screws that use the 5 mm wrench
before the 3 screws that use the 4 mm wrench.
