SECTION II
MASONRY INSERT INSTALLATION
INSTALLATION PRECAUTIONS
Extensive field and laboratory testing has shown that catalytic stoves perform best as fireplace inserts when:
1. A direct connect kit is used to connect the stove exhaust outlet directly to the masonry flue of the fireplace
when flue liner size is approximately the same size as the heater flue gas exit. A rain cap is also recommended
to keep flue dry thus allowing a hotter draft.
NFPA 211 CODE: The National Fire Protection Association code requires all fireplace insert heaters to be
positively connected from the heater to the flue liner (subject to State and Local codes in your area).
2. An equivalent sized flue liner is installed when the flue liner size is larger than the heater flue gas exit.
Connection must be from stove exhaust outlet extending the full height of the chimney and must include a rain
cap.
3. Location of chimney is interior (not on an outside wall).
Satisfactory results have been reported with installations other than as listed above. However, as all chimneys draw
differently, problems with performance may be encountered if steps are not taken to keep the chimney hot. A draft
between .03 and .06 inches of water is recommended for proper catalytic operation.
Use the following to complete the installation of the unit as an insert:
