2. Attach the heat exchanger lid and burner assembly onto the new heat exchanger with the six hex nuts
and perform the following:
a. Tighten nuts by hand in a cross pattern, similar to how the burner was tightened

Over-tightening will warp the heat exchanger lid and lid gasket, allowing fumes or
flames to leak.

a. Position the ignitor gasket on the heat exchanger lid, aligning it with the screw holes.
b. Carefully insert the ignitor into the heat exchanger assembly by sliding it straight down.
c. Tighten the two #2 Phillips screws screws by hand, then an extra ⅛ turn.
4. Reconnect the following cables:
The ignitor cable
The gas valve cable
The two electrical connectors to the fan.
