Vent Pipe Maintenance

Conduct an inspection of the venting system semiannually.
Recommended areas to inspect are as follows:
1. Check areas of the venting system which are exposed to
the elements for corrosion. These will appear as rust spots,
streaks, or, in extreme cases, holes. These components
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 fittings. It may be caused by
having excessive lateral runs, too many elbows, or 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 supports such as wall straps or plumbers'
tape for rigidity.

Opening and Removing Door

CAUTION: Do not open the glass door when the stove is
burning. Let the unit cool before opening the door.
Swing the front door open to access the two 5/32 screws
at the top of the glass frame and remove the two screws.
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 bot-
tom of the firebox.


Glass Door Cleaning and Maintenance

Cleaning: When cool, the glass may be cleaned with a clean,
soft cloth and glass cleaner. For cleaning white condensation
from the interior glass use KEL KEM 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 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: If the glass in your door is damaged
or broken, the complete door assembly (including gaskets)
must be replaced using part #H5991. The replacement door
assembly is available from your Lennox Hearth Products
dealer. The glass is neo-ceramic and alternative types must
not be used. See Page 22 for door removal instructions.
WARNING: Do not operate appliance with the glass panel
