INSTALLATION
Continued
We recommend that you install a sediment trap in
supply line as shown in Figure 20, page 16. Locate
sediment trap where it is within reach for cleaning.
Install in piping system between fuel supply and
heater. Locate sediment trap where trapped mat-
ter is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them from
going into fireplace controls. If sediment trap is
not installed or is installed wrong, fireplace may
not run properly.

is provided to allow accessibility
from the fireplace (see Figure 21).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
2. Route flexible gas line, included, from fire-
place control to equipment shutoff valve

3. Apply pipe joint sealant lightly to male
threads of gas connector attached to flex-
ible gas line/equipment shutoff valve (see
Figure 22).
CAUTION: Avoid damage to
gas control. Hold gas control
with wrench when connecting it

4. Check all gas connections for leaks (see
Checking Gas Connections). Feed lexible
gas line into fireplace. Make sure the entire
flexible gas line is in fireplace.
