Operating Precautions
Although the following operation precautions may have
been discussed earlier in this manual, they are stated
here for emphasis and to provide a quick reference.
Fireplace Precautions
1. Make sure all passageways of the chimney system
are clear and unobstructed.
2. Always open the damper before lighting a fire and
keep it open while the fire is burning. Do not close
the damper until the fire is completely out.
3. Be sure fire is provided with sufficient air to pre-
vent smoking, sooting and the formation of harmful
gases.
4. Always use a grate to support the fire. If the basket
grate burns out, it must be replaced by an approved
grate from CFM Corporation. Refer to replacement
models on Page 11.
5. Never burn scrap lumber, pine branches, trash, plas-
tics, flame colorants, soot cleaners or other chemi-
cals or compounds.
6. Never use liquid fuels or liquid fire starters.
7. Build your fire within approximately 1/2 inch of the
back of the firebox for good burning.
8. Always use care when adding wood to the fire and
when using fireplace tools (shovels, tongs, pokers,
etc.).
9. The first few fires should be small.
10. Do not overfire your fireplace.
11. Always keep the fireplace screens completely
closed while the fire is burning.
12. Never place any combustible objects (furniture,
pillows, etc.), closer than 24 inches from fireplace
(28 inches for WMC36/WMC42 and 32 inches for
EWF36A, EWF30, SHR48, SHR52 and TSH52 ).
13. Never let anything obstruct the air inlet/outlet grilles.
Glass Door Precautions
1. Always start the fire with the doors open.
2. When the doors are open, the screens must be
closed.
3. If unit has an adjustable flue damper, open flue
damper fully before opening the doors to prevent
smoke from escaping into the dwelling.
4. Do not build extremely large fires as they could dam-
age the finish and tempered glass.
5. Never allow the flames from the fire to contact the
door glass.
6. Always keep the bottom air inlet channel free of
obstructions.
7. To prevent discoloration on brass finished doors,
check finish for a protective plastic coating and re-
move if applicable.
8. Do not use abrasive cleaners on glass doors.
9. Do not clean while hot.
Maintenance and Care of Your Fireplace
Your fireplace is built to operate trouble-free with little
need for extensive time-consuming maintenance. As
with any such piece of equipment, your fireplace will
operate better and provide longer service if a few basic
housekeeping procedures are followed.
In the Fall -
Before the First Seasonal Use of the Fireplace
1. Inspect the roof in the area of the chimney and
remove any obstructions or foreign material such as
hanging tree limbs, broken tree branches, leaves,
etc.
2. Inspect the chimney top housing, removing any
foreign obstructions from cooling air inlets and bird
guard screen.
3. Inspect the flue for obstructions and foreign material
and remove them if any are found.
4. Creosote - Formation and Need for Removal
When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled moisture
to form creosote. The creosote vapors condense in the
relatively cool chimney flue of the slow burning fire. As a
result, creosote residue accumulates on the flue lining.
When ignited this creosote makes an extremely hot
fire. Inspect the flue for creosote buildup. The chimney
should be inspected at least once every two (2) months
during the heating season. If 1/8” or more of creosote
has accumulated, it should be removed to reduce the
risk of a chimney fire. Special tools and expertise are
required to clean a flue. It is recommended that a quali-
fied chimney sweep provide this service. To gain access
to the flue for inspection, and/or cleaning, the chimney
cap or top housing need to be removed. Refer to Figure
10 to identify the style of the top housing. Remove
screws as indicated.
5. Inspect the firebox hearth and firebrick liner for any
unusual deterioration or erosion.
