WinterWarm Small Insert
2000888
  When the insert is installed in a factory-built fire-
place:
• 
The factory-built chimney must meet type HT  
requirements of UL 103, ULC S629M or UL 127- 
1988, or be re-lined from the insert to the    
chimney top.
General Considerations / U.S.
• 
While not required in most jurisdictions in the 
U.S., CFM Corporation strongly recommends a 
full stainless steel chimney liner be installed for-
mthe insert to the chimney top to increase overall 
performance and reduce yearly maintenance.
• 
A masonry chimney must be well-constructed 
and must meet minimum code requirements.  
The chimney flue should have a code-approved 
liner made of masonry or pre-cast refractory 
tiles, straight or flexible stainless steel pipe, or a 
poured-in-place liner. An unlined chimney must 
be relined professionally.
• 
The chimney must have a nominal flue size of 6” 
(150mm) diameter, but no greater than 3 times  
larger.  A chimney larger than this must be re-
lined. 
Be aware that a chimney originally designed for fire-
place use may perform differently when used to vent 
an air-controlled appliance such as your WinterWarm 
Small Insert - even if the flue is less than 3 times larger 
than the flue collar. For example, a chimney on an 
outside wall may not heat up enough to sustain an 
adequate draft. Such a flue can often be improved if it 
is relined to reduce its size and/or insulated to keep it 
warmer.
• 
A positive flue connection must be made be-
tween the Insert and the first masonry tile or 
prefabricated metal chimney section. A positive 
flue connection consists of a plate that seals or 
replaces the fireplace damper and a section of 
chimney connector that passes through the plate 
into the chimney. The chimney connector must be 
a minimum equivalent to a 6” (150 mm) diameter 
opening and must be 24 gauge or heavier stain-
less steel.
Chimney Connection systems are available from a 
variety of manufacturers. Your Vermont Castings dealer 
can recommend a system that will best meet the re-
quirements of your particular installation.
Sealing Requirements / U.S.
• 
The chimney must be sealed off from room air, 
either by a plate at the damper level or by sealing 
the fireplace opening.
• 
Unused openings to the flue must be sealed with 
masonry to the thickness of the chimney wall.  
Openings sealed with pie plates or wallpaper are 
a hazard. In the event of a chimney fire, flames 
and smoke may be forced from the openings. 
Canada
In Canada (CAN/CSA-B365-M91, Section 5),  wheth-
er installed in a m or factory built  fireplace:
• 
A full chimney liner meeting ULC S635, Class III 
(stainless steel) must be installed from the insert 
to the chimney top, and securely attached to 
both. The damper may be removed to accommo-
date the liner.  
• 
The opening of the fireplace around the insert 
must be sealed to prevent room air passing to the 
fireplace cavity.
• 
Existing air-circulation chambers in a fireplace 
with a steel liner may not be blocked.
• 
Provision must be made for removal of the insert 
to clean the chimney flue.
• 
A permanent metal warning label must be affixed 
to the back of the fireplace stating the fireplace 
may have been altered to accommodate the in-
sert, and may be unsafe to use as a conventional 
fireplace. (A Fireplace Modification Tag is includ-
ed in the hardware bag inside the WinterWarm 
Small Insert.)
Minimum Fireplace Dimensions
The WinterWarm Small Insert will fit most masonry and 
factory-built fireplaces. To confirm that it will fit yours, 
measure the lintel depth, plus the height, width, and 
depth of your fireplace and hearth. Compare them to 
the measurements in the accompanying chart.  If you 
choose to install a new hearth over an existing fireplace 
hearth, be sure to take its thickness into consideration 
when measuring both front and back height of the 
fireplace.  
The unit can be installed virtually flush with the fireplace 
opening or it can extend up to 6³⁄₄” (172mm) onto the 
hearth. Figure 3 gives minimum and maximum dimen-
sions for fireplaces which will accommodate the Winter-
Warm Small Insert.  
NOTE:  The clearance between the WinterWarm Small 
Insert and the mantel, top trim and side trim cannot be 
reduced by installing shields.
Another requirement to consider is the clearance for 
movable items such as tables, bookcases, rugs, fur-
nishings, and your woodbox.  All combustible materials 
of this type should be a minimum of 48” (1220mm) from 
the front surface of the WinterWarm Small Insert.  Be 
sure that family members are aware of this requirement 
as well, so they too will keep objects a safe distance 
from the WinterWarm Small Insert.
