Twice A Year Check-Up - Lennox MP-420D Homeowner's Care And Operation Instructions Manual

Before Each Use
1. Clean the fi rebox of excessive ashes. Some
owners prefer to leave a small layer to insulate
the cold refractory below the grate which
helps fi re starting.
This fi replace has a factory supplied grate
attached, it is permissible to remove the
grate for cleaning; however, the grate must
be re-attached to the fi replace before the
next burn.
2. Keep the fi replace screens clean so combus-
tion air fl ows freely.
3. Spot check the brick-like refractory for small
cracks. Heat from the fi re expands it slightly.
When it cools, it contracts.

TWICE A YEAR CHECK-UP

Normally, twice a year, you should inspect your
fi replace following this list:
1. Inspect the opening in your chimney top and
remove any debris that could clog it. The cap
is usually held in place by four (4) screws,
which remove easily for checking or cleaning
the full length of the fl ue from above. Remove
the chimney top while wearing gloves to
guard against any sharp metal edges.
2. Inspect the entire fl ue from the top down
for obstructions such as birds nests, leaves,
etc. This may be done by using a fl exible
handled chimney cleaning brush. If the
chimney contains offset/return elbows; a
soft brush cleaning from the top down to any
elbow and then from the fi rebox up to the
offset/return section is the proper method.
The beam from a powerful fl ashlight will help
in this inspection.
3. Look up from inside the fi replace (damper
open) to see any obstructions in the lower
fl ue area. If present, shut the damper and
glass doors (if installed) to seal the fi rebox
and contain any soot that might fall.
4. Check the metal fl ashing and seals around
your chimney. Seal any cracks or loose
nailhead openings to prevent roof leaks.
5. Clean the fi rebox thoroughly by using a soft
brush or equivalent.
6. Check outside air inlet and free from any
obstructions.
7. Exposed stainless steel face may be cleaned
with a solution of baking soda and water:
Mix a tablespoon of baking soda in a cup of
water and spray on the exposed stainless
steel face. Wipe with a clean cloth. For
tough stains like smoke and soot stains, use
lubricant oil and steel wool (common spray
lubricants found where automotive supplies
are sold, work well).
Care and Cleaning of Your Glass Doors
Never clean the glass when the doors are hot.
Do not use ammonia or ammonia based glass
or household cleaner to clean the glass or the
door frame. An ammonia based cleaner will
damage the fi nish of the glass door.
Clean the glass doors by wiping with a damp
towel followed by a clean dry towel to remove
streaks.
Remove stubborn stains from the glass with a
mild soap solution and a towel dampened with
clean water. Dry with a clean dry towel.
• Never slam the glass door since it could
cause the glass to break.
• Extreme temperature changes can cause
glass breakage — do not build a hot fi re
and close the glass doors if the doors are
cold.
• If the tempered glass pane becomes
scratched or chipped, it creates a weakness
in the glass which can cause the glass to
break when heated. Replace the pane of
glass by contacting your nearest dealer.
If your fi replace does not have glass doors
installed, a damp sheet covering the fi replace
opening and sealed with masking tape will do.
Then clean the fl ue from the top down (if an
offset system, clean per Step 2) using a proper
size chimney brush with fl exible pole sections.
Don't open the doors or remove the sheet until
all soot has settled. Vacuum, don't sweep.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
CAUTION
Glass, metal frames, handles
and other components of the fi re-
place get hot. Use handles and
wear thermal insulating gloves
or other effective protection or
tool to open and close the doors
or screens.
ATTENTION
Les armatures en métal et le
verre deviennent très chauds.
Veillez à toujours utiliser les
poignées pour ouvrir et fermer
les portes.
WARNING
Be aware that safety glass is
unpredictable when hot and
may break, expelling hot glass
into the room. Advise all family
members to remain well away
from the fi replace when operat-
ing with doors closed to avoid any
possible personal injury.
AVERTISSEMENT

de verre chaudes sont impre-
visibles et peuvent se casser,
en projetant des morceaux
de verre tres chauds dans la
piece. Avisez tous les membres
de votre famille de demeurer
