Maximum output for natural gas is 36,900 BTU/hr at an efficiency of 82% with the fan on, 78.4% with the fan off; and 33,200 BTU/hr for propane at an efficiency of 83% with the fan on, 80% with the fan off. Minimum A.F.U.E. (Annual Fuel Utilization Efficiency) rating is 64%. Minimum inlet gas supply pressure is 4.5 inches water column for natural gas and 11 inches water column for propane. Maximum inlet gas pressure is 7 inches water column for natural gas and 13 inches water column for propane. Manifold pressure under flow conditions is 3.5 inches water column for natural gas and 10 inches water column for propane. This fireplace is approved for bathroom, bedroom and bedsitting room installations and is suitable for mobile home installation. No external electricity (110 volts or 24 volts) is required for the gas system operation. Expansion / contraction noises during heating up and cooling down cycles are normal and are to be expected. Change in flame appearance from "HI" to "LO" is more evident in natural gas than in propane. CARE OF GLASS, AND PLATED PARTS Do not use abrasive cleaners to clean plated parts. Buff lightly with a clean dry cloth. The glass is 3/16" ceramic glass available from your Napoleon / Wolf Steel Ltd. dealer. DO NOT SUBSTITUTE MATERIALS. Clean the glass after the first 10 hours of operation with a recommended gas fireplace glass cleaner. Thereafter clean as required. DO NOT CLEAN GLASS WHEN HOT! If the glass is not kept clean permanent discolouration and / or blemishes may result. Provide adequate ventilation and combustion air. Provide adequate accessibility clearance for servicing and operating the fireplace. Never obstruct the front opening of the fireplace. Objects placed in front of the fireplace must be kept a minimum of 48" away from the front face of the unit.

Minimum and maximum vent lengths, for both horizontal and vertical installations, and air terminal locations for either system are set out in this manual and must be adhered to. When using Napoleon venting components, use only the following vent kits: WALL TERMINAL KIT GD-222R, or 1/12 TO 7/12 PITCH ROOF TERMINAL KIT GD-110, 8/12 TO 12/ 12 ROOF TERMINAL KIT GD-111, FLAT ROOF TERMINAL KIT GD-112 or PERISCOPE KIT GD-201 (for wall penetration below grade) in conjunction with the various terminations, use either the 5 foot vent kit GD-220 or the 10 foot vent kit GD-330 For Simpson Dura-Vent, follow the installation procedure provided with the venting components. These vent kits allow for either horizontal or vertical venting of the fireplace. The maximum number of 4" flexible connections is four (excluding the fireplace and the air terminal connections). For optimum flame appearance and fireplace performance, keep the vent length and number of elbows to a minimum. The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify that it is unobstructed and undamaged. • All horizontal runs must have a 1 inch rise per foot in all cases using Napoleon flexible venting components. • Horizontal runs can have a 0 inch rise per foot using Simpson Dura-Vent or Napoleon rigid venting components. For optimum performance, it is recommended that all horizontal runs have a minimum . inch rise per foot using rigid venting. • Provide a means for visually checking the vent connection to the fireplace after the fireplace is installed. • Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1." air gap between the inner and outer liner all around is required for safe operation. • Use a firestop when penetrating interior walls, floor or ceiling. • For safe and proper operation of the fireplace follow the venting instruction exactly. • Deviation from the minimum vertical vent length can create difficulty in burner start-up and/or carboning. • Vent lengths that pass through unheated spaces (attics, garages, crawl space) should be insulated with the insulation wrapped in a protective sleeve to minimize condensation. • Purge all gas lines with the glass door of the fireplace open. Assure that a continuous gas flow is at the burner before closing the door. • Under extreme vent configurations, allow several minutes (5-15) for the flame to stabilize after ignition. • Eight (8") inches is the minimum bend radius allowed for the 7" diameter flexible air liner. When terminating vertically, the vertical rise is a minimum 36 inches and a maximum 40 feet above the fireplace. FIGURE 2 Do not radius vertical vent rises. FIGURES 4a When venting, the immediate horizontal run must be kept to a minimum of 10 inches or a maximum of 3 feet. FIGURES 4b W415-0100 / D / 01.13...
