This list contains replaceable parts used in your heater. When ordering parts, follow the

instructions listed under Replacement Parts on page 44 of this manual.

Each log includes reference numbers formed in the bottom or back of the log. The circled

number indicates the order it is placed on the burner system. The remaining numbers indicate

the size burner system the logs are designed to fit. For example, the first log for a 24 inch

burner system will include a circled 1 and also a 24. The circled 1 indicates this is the first log

to be installed. The 24 indicates this log belongs to a 24 inch log set.
