INSTALLATION REQUIREMENTS
WARNING : The X-62 Gas Log Insert must be installed in a vented, non-combustible fireplace with a working flue.
The fireplace must be approved for burning solid fuel. It cannot be installed in a bathroom, or in any
room where sleeping accommodations are provided.
FIREPLACE DIMENSIONS
The X-62 must be installed in a fireplace with dimensions equaling or exceeding each of those listed in the chart
below. (See Fig. 1.)
MINIMUM FIREPLACE DIMENSIONS
DIMENSION INCHES ( MM )
WIDTH 30 ½ (775)
HEIGHT 24 (610)
DEPTH 16 ½ (420)
NOTE: A Faceplate/Surround large enough to cover the gap between the X-62 and the existing fireplace also
should be purchased. (See Fig. 2.)
CHIMNEY OPENING
The X-62 must be installed in a fireplace with a chimney opening equaling or exceeding the minimum opening
listed in the chart below
—note that
shorter chimneys require larger openings.
NOTE:
Massachusetts requires that the existing fireplace flue damper must be removed or
permanently welded in the "open" position.

CAUTION : The X-62 should not be installed in any fireplace that is normally subject to severe downdrafts.
Downdraft conditions exist if, when starting a wood fire, it is difficult to establish a good upward draw
(i.e., smoke and cold air flow into the room rather than up the chimney), or if it is necessary to open a
door or window to get an upward flow of air established. For homes with downdraft conditions, we
recommend the installation of a ―lined‖ heater-rated fireplace insert (such as the Mendota DV-30 or DV-
40).
NOTE: High winds or severely cold temperatures can cause downdrafts in any fireplace,
especially those with large flues. These occasional downdrafts do not preclude the use of a X-62.
NOTE: Do not connect the X-62 to a chimney flue serving a second solid-fuel-burning appliance.
NOTE: A chimney cap must be used with the X-62 to prevent rain from damaging the appliance.
MANTEL CLEARANCE
Combustible mantels located above the X-62 must conform to the minimum clearance distances listed in the chart
below. A mantel that is 8‖ (203 mm) deep
or less
must be at least 15‖ (381 mm) above the top of the exhaust
opening of the appliance. For mantles deeper than 8‖ (203 mm), the minimum clearance increases by 2‖ (51 mm)
for every 1‖ (25 mm) increase in mantle depth. (See Fig. 3.)

Round Chimney Area Reference:
6‖ dia. = 28.7 sq. in.
7‖ dia. = 38.5 sq. in.
8‖ dia. = 50.3 sq. in.
10‖ dia. = 78.5 sq. in.
For Masonry flues, multiply width
by depth of flue opening.
