Figure 19 - Attaching Gas Lines Together
NOTICE: Most building codes do
not permit concealed gas con-
nections. A flexible gas line is
provided to allow accessibility
from the fireplace (see Figure 19).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
3. Route gas line (provided by installer)
from equipment shutoff valve to fire-
place. Route flexible gas supply line
through one of the access holes.
Figure 17 - Gas Connection
* Purchase the optional CSA design-certi-
fied equipment shutoff valve from your
dealer. See Accessories, pages 24 and 25.

CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
We recommend that you install a sediment
trap in supply line as shown in Figure 17.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and heater. Locate sedi-
ment trap where trapped matter is not likely
to freeze. A sediment trap traps moisture
and contaminants. This keeps them from
going into fireplace gas controls. If sedi-
ment trap is not installed or is installed
wrong, fireplace may not run properly.
4. Attach the flexible gas line to gas sup-
ply (see Figure 19). Check tightness of
flexible gas line attached to gas regu-
lator of fireplace (see Figure 19).
5. Check all gas connections for leaks. See
Checking Gas Connections, page 12.
6. Replace log base assembly back into
fireplace. Feed flexible gas line into fire-
place base area while replacing log base
assembly. Make sure the entire flexible
gas line is in fireplace base area. Reat-
tach log base assembly to fireplace with
screws removed in step 2.
Check your building codes for any special
requirements for locating equipment shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged fireplace valves.
