General Vent Pipe Maintenance

Conduct an inspection of the venting system semi-annually. Recommended areas to inspect are as follows:

1.Check areas of the venting system which are exposed to the ele- ments for corrosion. These will appear as rust spots or streaks and in extreme cases, holes. These component should immediately be replaced.

2.Remove the cap and shine a flashlight down the vent. Remove any bird nests or other foreign material.

3.Check for evidence of excessive condensate, such as water droplets forming in the inner liner and subsequently dripping out at joints. Continuous condensate can cause corrosion of caps, pipe and fit- tings. It may be caused by having excessive lateral runs, too many elbows and exterior portions of the system being exposed to cold weather.

4.Inspect joints to verify that no pipe sections or fittings have been disturbed and consequently loosened. Also check mechanical sup- ports such as wall straps or plumbers’ tape for rigidity.

Opening and Removing Glass Door

The doors on the stove may be opened to provide an unobstructed view of the fire or to provide greater access to the firebox. To open the doors, when the stove is cool, simply pull on the right door and it will swing open. The left door can then also be swung open.

CAUTION: Do not open the glass door when the stove is burning. Let the unit cool before opening the door.

Lift off the stove top to access the glass door. At the top of the glass door are two spring-loaded “I” (looped) bolts. Pull each loop forward while rotating at 90 degrees, releasing the top of the glass door. To remove the door, grasp it firmly with both hands and lift it up. The glass door is fragile so it is important to place it in a secure spot until reinstalled. To reinstall the door, the bottom of the door must be inserted in the slot at the bottom of the firebox. The loops on the spring loaded “I” bolts must be pulled forward and down into the receiving bracket on the door to apply pressure against the door. The latches need pulled forward and rotated at 90 degrees. Once the loops are in the receiving bracket you will then rotate them back 90 degrees so they are at the angle shown in Figure 36.

Glass/Door Maintenance

Cleaning: When cooled, the glass may be cleaned with a clean, soft cloth and a household glass cleaner. For cleaning white condensation from the interior glass use a gas stove glass cleaner available from your stove dealer. Use of caustic or abrasive cleaners may damage glass. Gold or nickel plated trim must be cleaned with a household glass cleaner or denatured alcohol and a soft cloth before firing or fingerprints and stains will remain permanently. Never use abrasive polish to clean the gold or nickel as it will ruin the finish. DO NOT operate stove with broken glass. DO NOT clean door or glass when hot. DO NOT abuse glass door by striking or slamming shut. DO NOT use substitute materials if replacing glass. DO NOT spray commercial glass cleaner with ammonia on the door and glass gasket as it may dissolve the gasket glue.

WARNING: Do not operate appliance with the glass panel removed, cracked, or broken. Do not remove glass door while the stove is hot. Replacement of the glass door should be done by a qualified service technician.

Glass Replacement: Should the glass be damaged, both the glass and the gasket should be replaced. The replacement glass and gasket are available from your Lennox Hearth Products dealer. The glass is neo-ceramic and alternative types must not be used. To install the new glass and gasket: Remove the old glass and gasket. The glass is held in place by two metal tabs located on the sides of the glass door frame. Using a flat-bladed screwdriver or pliers, bend the tabs up to release the old glass from the frame. Should the old glass be broken, care should be used in removing and discarding the glass so as not to injure yourself. Install the new glass and gasket by positioning the frame with the bent lips up and set the glass on the frame. (The glass is square so there is no top or bottom). Slide the glass so the gasket is down against the 1/8” lip. Using pliers, bend the metal tabs firmly down onto the gasket on the glass. The tabs must be bent into the gasket to ensure a tight seal of the glass to the stove. Install the glass frame on the stove. See instructions on this page for removing and replacing the glass door.
