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 10).
Determining Minimum Mantel Clearance
When using a Hood
If minimum clearances in Figure 6, page 10
are not met, you must have a hood. When
using a hood there are still certain minimum
mantel clearances required. Follow minimum
clearances shown in Figure 7, page 10 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

INSTALLING HEATER ASSEMBLY
CAUTION: Do not remove the
data plates attached to the heater
base assembly. The data plates
contain important warranty and
safety information.
WARNING: If installing in a
sunken fireplace, special care
is needed. You must raise the
fireplace floor to allow access to
heater control panel. This will in-
sure adequate air flow and guard
against sooting and controls be-
ing damaged. Raise fireplace floor
with noncombustible material.
Make sure material is secure.
CAUTION: Do not pick up
heater assembly by the logs. This
could damage heater. Only han-
dle base assembly by grates.
IMPORTANT: Make sure the heater burner is
level. If heater is not level, heater will not work
properly.
IMPORTANT: Remote receiver module is at-
tached to the valve by a velcro strap. This module
needs to remain where installed. If removed and
wires cross, this can cause the remote to fail.
