INSTALLATION
Continued
We recommend that you install a sediment trap in supply line as
shown in Figure 20, page 14. Locate sediment trap where it is within
reach for cleaning. Install in piping system between fuel supply and
heater. Locate sediment trap where trapped matter 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.
CONNECTING EQUIPMENT SHUTOFF VALVE
TO HEATER CONTROL
Installation Items Needed
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not provided)
1. Open lower louver (see Figure 21).
NOTICE: Most building codes do not permit con-
cealed gas connections. A flexible gas line is pro-
vided to allow accessibility from the fireplace (see
Figure 31). The flexible gas supply line connection to
the equipment shutoff valve should be accessible.
2. Route flexible gas line, included, from fireplace control to equip-
ment shutoff valve through side access holes in outer casing.
3. Apply pipe joint sealant lightly to male threads of gas connec-
tor attached to flexible gas line/equipment shutoff valve (see
Figure 22).
CAUTION: Avoid damage to regulator. Hold gas
regulator with wrench when connecting it to gas piping
and/or fittings (Thermostat-Controlled Models Only).
CAUTION: Avoid damage to gas control. Hold gas
control with wrench when connecting it to gas piping
and/or fittings (Remote-Ready Models Only).
4. Check all gas connections for leaks. See Checking Gas Con-
nections, page 16. Feed flexible gas line into fireplace. Make
sure the entire flexible gas line is in fireplace.
