UNVENTED PROPANE/LP GAS FIREPLACE
INSTALLATION
Continued
INSTALLING GAS PIPING TO FIREPLACE LOCATION
WARNING: A qualified ser- vice person must connect fire- place to gas supply. Follow all local codes.
CAUTION: Never connect fire- place directly to the propane/LP supply. This fireplace requires an external regulator (not supplied). Install the external regulator be- tween the fireplace and propane/ LP supply.
Installation Items Needed
Before installing fireplace, make sure you have the items listed below.
•external regulator (supplied by installer)
•piping (check local codes)
•sealant (resistant to propane/LP gas)
•equipment shutoff valve *
•test gauge connection *
•sediment trap
•tee joint
•pipe wrench
•approved flexible gas line with gas connec- tor (if allowed by local codes) (not provided)
*A CSA
The installer must supply an external regu- lator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incom- ing gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure
24.Pointing the vent down protects it from freezing rain or sleet.
CAUTION: Use only new, black iron or steel pipe.
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 25).
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 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.

Vent Pointing Down
Figure 24 - External Regulator with Vent Pointing Down
We recommend that you install a sediment trap in supply line as shown in Figure 25. 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.
