between door gasket and combustion chamber
shield, align the screws on the inner door with
the screw holes on the combustion chamber and
tighten with 1/4” nut driver or 1/4” socket & ratchet
(Figure 97). After tightening the inner door
screws, visually inspect area around door
gasket and skirt for spaces or gaps. The door

tighten nut with an 3/4” open end wrench or crescent
wrench (Figure 100).

of the gas control valve/thermostat, gently pushing
each connector up snapping into place (Figure 100).

22. As the burner is heating (view flames through
viewport), test the manifold tube connection at the gas
control valve/thermostat by brushing on an approved
noncorrosive leak detection solution (IMPORTANT:
Do Not splash any solution onto any electrical
connections) (Figure 100).
