3.2 factory built fireplace
49.2
The following installation requirements must be observed when installing solid fuel burning inserts into factory
built fireplaces.
A.
The factory built fireplace must be listed per UL 127 or ULC S610.
B.
Clearances to any combustible material surrounding this insert as identified must be followed.
These clearance requirements supersede any pre-existing facing material clearances listed for the
factory built fireplace.
C.
Installation must include a full height listed chimney liner meeting HT requirements (2100°F/1149°C)
as required in UL 1777 (U.S.) or ULC S635 (Canada). The liner must be securely attached to the
insert flue collar and the chimney top.
D.
Means must be provided to prevent room air passage to the chimney cavity of the fireplace. This may
be accomplished by sealing the damper area around the chimney liner, or sealing the appliance front.
E.
The air flow within and around the appliance shall not be altered by the installation of the insert (i.e. no
louvres or cooling air inlet or outlet ports are blocked), unless specifically tested as such for each
factory built fireplace manufacturer and model line.
F.
Alteration of the appliance in any manner is not permitted with the following exceptions;
A. External trim pieces which do not affect the operation of the appliance may be removed providing
they can be stored on or within the fireplace for reassembly if the insert is removed.
B. The chimney damper may be removed to install the chimney liner.
G.
Circulating air chambers (i.e. in a steel fireplace liner or metal heat circulator) shall not be blocked.
H.
Means must be provided for removal of the insert to clean the chimney flue.
I.
Inserts that project in front of the fireplace must be supplied with appropriate support means.
J.
A permanent metal warning label must be attached to the back of the fireplace stating that the
fireplace must be restored to its original condition for safe use without the insert.
note:
Using a louvered face plate (surround) complies with this requirement.
