Purchase theCSA design-certified equipment shutoff valve from your retailer.For propane/LP connection only, the installer must supply anexternal regulator. The external regulator will reduce incoming gaspressure. You must reduce incoming gas pressure to between 11 and14 inches of water. If you do not reduce incoming gas pressure,fireplace regulator damage could occur. Install external regulatorwith the vent pointing down as shown in Figure 30. Pointing the ventdown protects it from freezing rain or sleet.WARNING: A qualified service person must con-nect fireplace to gas supply. Follow all local codes.CAUTION: For propane/LP units, never connectfireplace directly to the propane/LP supply. Thisheater requires an external regulator (not supplied).Install the external regulator between the fireplaceand propane/LP supply.Figure 30 - External Regulator with Vent Pointing Down(Propane/LP Only)Propane/LPSupply TankExternalRegulatorVentPointingDownFIREPLACE INSTALLATIONInstalling Optional Blower Accessories (Cont.)Installing Gas Piping to Fireplace LocationFIREPLACE INSTALLATIONContinued5.
