C. Logs/Grate and Valve Assembly Removal

It may become necessary to remove the logs/grate and valve assembly. This task should be performed by a quali- ﬁed service technician. The base pan does not need to be removed to service the burner assembly.

1.Remove the two top logs from the log/grate assembly. These logs are not secured to the assembly with screws. See Figure 3.2.

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 CD4842IR-C model). There are 4 screws per side panel, Figure 3.5 shows the 2 screws on the bottom of panels and Figure 3.6 shows the 2 screws on the top of the panels. The 2 other screws for CD4842IR-C models are located in back wall of ﬁrebox as shown in Figure 3.7. One is up by exhaust bafﬂe and the other is behind logs and near ﬁreplace bottom.
