CHIMNEY CLEARANCES
CHIMNEY
(REFER TO CHIMNEY AND CHIMNEY CONNECTOR MANUFACTURER’S INSTRUCTIONS)
Contact your local building authority for approved methods of installation
NOTE: Canadian installations require a full reline of the chimney.
1. This appliance requires a masonry or pre-manufactured chimney listed to ULCS629 (Canada) and UL 103 HT (USA)
sized correctly.
2. If a masonry chimney is used it is advisable to have your chimney inspected for cracks and check the general
condition before you install your unit. Re-lining may be required to reduce fl ue diameter to the appropriate functional
size.
3. The chimney should extend at least 3' (914 mm) above the highest point where it passes through the roof, and at least
2' (610 mm) higher than any portion of a building within 10' (3 m). Figure 14.
4. The chimney connector shall not pass through an attic, roof space, closet, concealed space, fl oor, ceiling, wall or any
partition of combustible construction.
5. The minimum overall height of your chimney should be 15' (5M) from the fl oor.
6. Do not use makeshift compromises during installation.
At the very least, inspect the chimney connector and chimney at least once every month during the heating season to
determine if a buildup of creosote or soot has occurred. If a signifi cant layer of creosote has accumulated (1/8" (3mm)
or more], or if soot has accumulated, either should be removed to reduce the risk of a chimney fi re. Failure to keep the
chimney and connector system clean can result in a serious chimney fi re.
The conditions for a chimney fi re develop as follows: 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 fl ue of a slow burning fi re. As a result creosote residue accumulates on the fl ue lining. Creosote is a fl ammable
and, when ignited, make an extremely hot fi re within the fl ue system which can damage the chimney and overheat
adjacent combustible material.
