Anleitung Zusammenfassung
Close the tap gently but securely after completing the check. The manifold (outlet) tap is to the right of the inlet tap. To check manifold pressure (with the fireplace burning at the high burn setting) insert a small flat bladed screwdriver into the tap and turn a half turn counterclockwise. Cover the tap with the line from the manometer and check the pressure. Again close the tap gently but securely after completing the check. Check the taps for gas leaks with a gas leak test solution (retighten if necessary). If the pressure is not sufficient, make sure the gas supply line is large enough, the supply regulator is properly adjusted and the total gas load for the residence does not exceed the amount supplied. Propane tanks are at pressures that will cause damage to valve components. Verify that the tanks have step down regulators to reduce the pressure to safe levels. These appliances must be isolated from the gas supply piping system (by closing their individual manual shut-off valve) during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa). These appliances and their individual shut-off valves must be disconnected from the gas supply piping system during any pressure testing of that system at pressures greater than 1/2 psig (3.5 kPa). Note: Theapplianceanditsindividualshut-offvalvemustbedisconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig. The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. Check with your gas supplier or plumber.

This appliance can only be operated using propane gas (LP) if a certified fuel conversion kit provided by Lennox Hearth Products is installed by a qualified service technician. Also check the orifice size on the label on the igniter bracket. It must be the correct size for the fuel and altitude. Do not run propane tank dry. Running the tank dry may cause a hazardous condition due to pressure drop in empty tank. Solid fuel is NOT to be used with this unit. NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE. Increasing Efficiency and Hot Air Movement Increasing Efficiency and Hot Air Movement e the heat output and air movement to different rooms in the house. Grills: If your Ravelle™ 42 gas fireplace is installed in a cabinet or a chase, heat can be drawn from these enclosures and circulated into the living area by cutting one or two openings covered by a register or Grill. Opening and Grill into Figure 34 Possible Opening and Grill Locations on Cabinet Whole Home Comfort System: The Whole Home Comfort System is a very inexpensive and efficient way to move air into and heat other areas of the house. In the bottom of the Ravelle™ 42 gas fireplace are four inch and Six inch (152 mm) diameter knock-out plates. Four inch (102 mm) or six inch (152 mm) diameter return air ducting may be fastened to the bottom of the fireplace, run into another room in the house and terminated with a grill. When the fireplace is burning, with or without the fireplace fan running, air is drawn from a distant room (lowering the pressure in that room) through the return air duct into the bottom of the fireplace. The air then passes through the outer shell and heat exchanger of the fireplace and into the room in which the fireplace is located. The hot air in the fireplace room moves through an open doorway or hall into the low pressure room from which the air was drawn. This system functions well by convection even without the use of the fireplace fan. Six inch (152 mm) diameter ducting moves more air than four inch diameter ducting. Figure 33 Adjoining Room Ducting in uninsulated areas of a house (for example in the crawl space) should be wrapped in insulation to ensure maximum heat retention. Check local building codes - some areas may require firestops when the duct passes from room to room. Figure 35 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
