DIRECT-VENT FIREPLACE (NATURAL/PROPANE/LP)
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: For propane/LP units, never connect heater di- rectly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater 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)
•manual shutoff valve *
•test gauge connection *
•sediment trap
•tee joint
•pipe wrench
•approved flexible gas line with gas con- nector (if allowed by local codes) (not provided)
CAUTION: Use only new, black iron or steel pipe. Inter-
Installation must include a manual 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 35).

IMPORTANT: Install main gas valve (manual shutoff valve) in an accessible lo- cation. The main gas valve is for turning on or shutting off the gas to the appliance.
Check your building codes for any special requirements for locating manual 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.
We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 35. Locate sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sediment trap/drip leg where trapped matter is not likely to freeze. A sediment trap traps moisture and contami- nants. This keeps them from going into fireplace gas controls. If sediment trap/drip leg is not installed or is installed wrong, fireplace may not run properly.
*An A.G.A.
For propane/LP connections only, the in- staller must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of

3" Minimum 
Natural - From Gas Meter (5" W.C. to 10.5" W.C. Pressure )
Propane/LP - From External Regulator (11" W.C. to 14" W.C. Pressure)
water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 34. Pointing the vent down protects it from freezing rain or sleet.
