5.1.2 Top Shell (Continued)
Installation
1.
Check that the Top Shell is fitted with two gaskets, one on each end. Inspect the end gaskets and replace if
damaged.
Note: The gasket around the square hole should stay fixed to the Top Housing.
Inspect the gasket and replace if damaged.
2.
Check the condition of the side seam gaskets on the bottom shell. Replace if damaged.
3.
Check that the spring washer is installed on the Igniter electrical post.
4.
Check that the Igniter electrical connection is in place on the Igniter. Place the Top Shell over the Top Housing,
and ensure that the holes in the Top Shell line up with the holes in the Bottom Shell.
Note: Ensure that the Wiring Harness is properly tucked inside the Top Housing
and the Top Shell does not put pressure on any components or other wires.
Note: The Top Shell has seam tabs which fit inside the mating tabs on the Bottom
Shell.
Tip: Make sure the locking tabs fit together properly, then gently push the Top
Shell onto the Bottom Shell to compress the gaskets.
5.
Using a 1/4" nut driver or socket, install the nine (9) self tapping screws and two (2) machine screws. Ensure
that the seals between the two shells are properly in place.
Note: The gaskets and the seals along the edges of the Top and Bottom Shells
prevent air leakage during operation.
6.
Check that the Igniter electrical connection is in place on the Igniter. Screw the Igniter Hatch into place. DO
NOT over tighten. Ensure that the Hatch is fitting properly to the shape of the Top Shell.
Note: The Igniter Hatch must be properly in place to prevent air leakage during
operation and to ensure a good electrical connection for the Igniter.
7.
Place the Heater on the Test Stand and check for operation (ref. 3.1).
