These logs are not secured to the assembly with screws.

4. The standard metal refractory will have to be removed
in order to access the valve assembly. This is done
by removing 8 screws (10 screws for CD4842IFTR/
CD4842IFTLR models). There are 4 screws per side
panel, Figure 4.6 shows the 2 screws on the bottom of
panels and Figure 4.7 shows the 2 screws on the top
of the panels. The 2 other screws for CD4842IFTR/
CD4842IFTLR models are located in back wall of firebox
as shown in Figure 4.8. One is up by exhaust baffle
and the other is behind logs and near fireplace bottom.
