II. Flue Systems
A good chimney is essential. This room heater must be connected to (1) a listed Type HT
(2100°F) chimney per UL 103 or ULC S629, or (2) a code-approved masonry chimney with a flue
liner.
Masonry Flue System:
It is important to make sure that the masonry chimney is structurally
sound and on a solid foundation. The masonry chimney must have a liner installed within the
chimney construction. An unlined chimney is not safe with solid fuel systems, and may result in a
house fire. The liner may be constructed with a structurally sound clay liner or a stainless steel
liner. If using an existing masonry chimney, be sure to have the chimney examined and cleaned
by a chimney professional. The structural foundation of the chimney and liner is important. If
existing clay liner is cracked or damaged, it is recommended to re-line the chimney with a
stainless steel liner. Be sure the masonry chimney is compatible with the local building codes and
requirements.
Factory Built System:
The factory built chimney must be a listed Type HT (2100°F) chimney per
UL 103 or ULC S629. If using an existing factory built Class A chimney it must be inspected and
cleaned by a certified chimney professional, before use. With Factory Built Chimneys the chimney
manufacturer’s clearances and distance requirements must be followed. It is also important to
abide by the rules and regulations of local jurisdictions upon chimney installation.
