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 20).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
INSTALLATION

Figure 18 - Gas Connection
* Purchase the optional CSA design-certi-
fied equipment shutoff valve from your
dealer. See Accessories, pages 22 and 23.
Installation must include an equipment
shutoff valve, union, and plugged 1/8" NPT
tap. Locate NPT tap within reach for test
gauge hook up. NPT tap must be upstream
from fireplace (see Figure 17, page 10).
IMPORTANT: Install equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.
Check your building codes for any special
requirements for locating equipment shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged fireplace valves.
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 18.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and fireplace. Locate
sediment trap where trapped matter is not
likely to freeze. A sediment trap traps mois-
ture and contaminants. This keeps them
from going into fireplace gas controls. If
sediment trap is not installed or is installed
wrong, fireplace may not run properly.
