MANTEL CLEARANCES
In addition to meeting noncombustible mate-
rial clearances, you must also meet required
clearances between fireplace openings and
mantel shelf on each side of the fireplace. If
you do not meet the clearances listed below,
you will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between man-
tel shelf and top of fireplace opening, a hood
is not required (see Figure 6, page 11).
Determining Minimum Mantel Clearance
When using a Hood
If minimum clearances in Figure 6 are not
met, you must have a hood. When using a
hood there are still certain minimum mantel
clearances required. Follow minimum clear-
ances shown in Figure 7, page 11, when
using hood.
NOTICE: Surface temperatures
of adjacent walls and mantels be-
come hot during operation. Walls
and mantels above the firebox
may become hot to the touch.
If installed properly, these tem-
peratures meet the requirement
of the national product standard.
Follow all minimum clearances
shown in this manual.
NOTICE: If your installation does
not meet the minimum clear-
ances shown, you must do one
of the following:
• operate the logs only with the
flue damper open
• raise the mantel to an accept-
able height
• remove the mantel
FLOOR CLEARANCES
A. If installing appliance on the floor level,
you must maintain the minimum distance
of 14" to combustibles (see Figure 8).
B. If combustible materials are less than 14"
to the fireplace, you must install appliance
at least 5" above the combustible flooring
(see Figure 9).

ACCESSORY FOR VENTED
OpERATION
Note: When used as a vented heater, ap-
pliance must be installed only in a solid-fuel
burning fireplace with a working flue and con-
structed of noncombustible material.
For Massachusetts Residents Only: Instal-
lation of this vented gas log set in the Com-
monwealth of Massachusetts requires the
damper be permanently removed or welded
in the fully open position.
If your heater is a manually controlled model,
you may use this heater as a vented product.
There are three reasons for operating your
heater in the vented mode:
1. The fireplace does not meet the clearance
to combustibles requirements for vent-
free operation
2. State or local codes do not permit vent-
free operation
3. You prefer vented operation
If reasons number 1 or 2 above apply to you,
you must permanently open chimney flue
damper. You must install the damper clamp
accessory (to order, see Accessories, page
29). This will insure vented operation (see
Figure 10, page 13). The damper clamp will
keep damper open. Installation instructions
are included with clamp accessory.
