CARE OF GLASS, AND PLATED PARTS
Do not use abrasive cleaners to clean glass. Buff lightly with a clean dry cloth. The glass is 3/16” tempered glass avail- able 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 fi replace 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.

VENTING
Note: If for any reason the vent air intake system is disas- sembled; reinstall per the instructions provided for the initial installations.
VENTING LENGTHS & AIR TERMINAL
LOCATIONS
For safe and proper operation of the fireplace follow the venting instuction exactly.
Deviation from the minimum vertical vent length can create diffi culty in burner
Provide a means for visually checking the vent connection to the fi replace after the fi replace is installed.
Vent lengths that pass through unheated spaces (attics, ga- rages, crawl spaces) should be insulated with the insulation wrapped in a protective sleeve to minimize condensation.
When using NAPOLEON® venting components, use only approved Wolf Steel Ltd. fl exible vent components with the following termination kits: WALL TERMINAL KIT GD622, or 1/12 TO 7/12 PITCH ROOF TERMINAL KIT GD610, 8/12 TO 12/12 ROOF TERMINAL KIT GD611, FLAT ROOF TERMINAL KIT GD612. With fl exible venting, in conjunction with the various terminations, use either the 5 foot vent kit GD620 or the 10 foot vent kit GD630. These vent kits allow for either horizontal or vertical venting of the fi replace.
The maximum allowable vertical vent length is 40 feet. The maximum number of allowable 8” vent connections is three horizontally or vertically (excluding the fi replace and the air terminal connections).
For optimum fl ame appearance and fi replace performance, keep the vent length and number of elbows to a minimum. The air terminal must remain unobstructed at all times. Ex- amine the air terminal at least once a year to verify that it is unobstructed and undamaged.
When venting, the horizontal run must be kept to a minimum of 16 inches or a maximum of 20 feet. If a 20 foot horizontal run is required, the fireplace must have a minimum vertical rise immediately off the fireplace of 57 inches. FIGURES

FIGURE 3
For optimum performance, it is recommended that all horizontal runs have a minimum ¼ inch rise per foot. Provide a means for visually checking the vent connec- tion 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 3/4” 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.
If vertical rises greater than 57 inches are necessary, the increased rise must be deducted from the horizontal run.
