The heater has a unitized base, a front log and
a top twig. It is important to follow the
instructions to place the logs properly over the
burner assembly.
1. Place the front log as shown in Figure 9 (A) .
Position the front log so it fits between the
burner and the front grate bars, resting com-
pletely on the grate base.
2. Place the unitized log set over the burner
assembly as shown in Figure 9 (B) . Be sure
the unitized log set is against the sides of the
burner and is resting down completely over
the grate.
3. When placing the unitized log set over
the burner assembly and resting it against
the sides of the burner, make sure the bot-
tom of the log set sits down completely over
the grate as shown in Figure 9 (C) .
4. Place and lock the top twig over the twig
pins as shown in Figure 9 (D) .
5. For an optimum flame, be sure that the
unitized log set rests against the burner at the
two places shown in Figure 9 (E) .
