D. Wall and Mantel Temperatures
ANSI/CSA Standards
The American National Standards Institute (ANSI) and
Canadian Standards Association (CSA) write the safety
and performance standards to which all gas replaces
are tested. The following are the allowable temperatures
around and on a gas replace per the ANSI/CSA
standards:
Combustible Mantel and Surfaces around a Fireplace
The allowable temperature rise above ambient is
117°F for all exposed combustible surfaces around the
replace, including the mantel, when installed according
to the installation instructions. Non-combustible surfaces
and mantels do not have a maximum temperature limit;
however the installation instructions must still be followed
for any restrictions on placement of non-combustible
materials on or around the replace.
Example: The mantel above a replace in a room
that is 70°F is allowed to reach but not exceed
187°F (70°F+117°F = 187°F).
E. Good Faith Wall Surface/TV Guidelines
If installing a television (TV) above the appliance, see
appliance Installation Manual Section 2.B.
NOTICE: Surface temperatures listed above are taken with
a temperature measuring probe as prescribed by the test
standard used for appliance certication. Temperatures
on walls or mantels taken with an infrared thermometer
may yield increased temperatures of up to 30 °F (17 °C) or
more depending on the thermometer settings and material
characteristics being measured. Use appropriate nishing
materials that are able to withstand these conditions.
For additional nishing guidelines, see Section 8 in the
appliance installation manual.
F. Before Lighting Appliance
Before operating this replace for the rst time, it is rec-
ommended that a qualied service technician:
• Verify all shipping materials have been removed from

IFT-RC150 remote controls. The IFT-ECM switch
must be in this position to pair the IFT-ECM with the
IFT-ACM (if installed), and/or IFT-RC400 and IFT-
RC150 remote controls. See the IFT-RC400 or IFT-
RC150 installation manual for detailed instructions
on pairing the IFT-ECM with the remote controls.
After successfully pairing a IFT-RC400, all installed
accessories can be controlled by the IFT-RC400
(see IFT-RC400 user manual). The RC150 allows
the user to turn ON/OFF the ame in the appliance
and activate the Cold Climate mode if desired. The
IFT-ECM has a safety feature that will automatically
shut down the replace after 9 hours of continuous
operation without receiving a command from the
IFT-RC400 or IFT-RC150.

Frequently Asked Questions and Troubleshooting
A. Frequently Asked Questions
Contact your dealer for additional information regarding operation and troubleshooting. Visit www.hearthnhome.com to
locate a dealer.
ISSUE SOLUTIONS
Condensation on the glass
This is a result of gas combustion and temperature variations. Prior to appliance being turned
on, the inside of the glass has cooled below the dew point producing a byproduct of combus-
tion: water in the form of condensation. As the replace glass warms, the condensation will
disappear.
In the summer, the inside of your replace contains hot humid air from outdoors. When the air
from outdoors contacts glass cooled below the dew point by your air conditioning, moisture in
that air will condense.
Blue ames
This is a result of normal operation and the ames will begin to yellow as the replace is
allowed to burn for 20 to 40 minutes.
Erratic ames
Verify that the glass assembly is correctly installed and that all glass latches are engaged over
the tabs on the glass frame.
Vent bae/ue restrictor may be needed when long vertical vent runs are used. Refer to
Installation Manual Replace with Section 4 Vent Diagrams.
Odor from replace
When rst operated, this replace may release an odor for the rst several hours. This is caused
by the curing of the paint and the burning o of any oils remaining from manufacturing. Odor
may also be released from nishing materials and adhesives used around the replace. These
circumstances may require additional curing related to the installation environment.
Film on the glass
This is a normal result of the curing process of the paint and logs. Glass should be cleaned
within 3 to 4 hours of initial burning to remove deposits left by oils from the manufacturing pro-
cess. A non-abrasive cleaner such as gas replace glass cleaner may be necessary. Contact
your dealer.
Metallic noise
Noise is caused by metal expanding and contracting as it heats up and cools down, similar to
the sound produced by a furnace or heating duct. This noise does not aect the operation or
longevity of the replace.
Is it normal to see the pilot ame burn
continually?
In an intermittent pilot ignition system (IPI), the pilot ame should turn o when appliance is
turned o. Some optional control systems available with IPI models may allow pilot ame to
remain lit.
Power Outages
(battery backup)
This appliance can be operated on battery power in the event of a power outage. To access
the battery pack, the decorative barrier front, mesh and glass assembly must be removed.
Refer to Section 3 for more details.
Wall above appliance feels hot to
the touch.
No action necessary. This appliance ships with a non-combustible material attached. Speci-
cations of the attached non-combustible material are listed in the Installer’s Manual for this
appliance.
