Figure 3.3 Maximum Wall Surface Temperatures Above Appliance
E. Good Faith Wall Surface/TV Guidelines
Figure 3.3 shows the approximate wall surface temperatures
above the center of the appliance at various heights above
the appliance opening.
NOTICE: Surface temperatures listed above are taken with
a temperature measuring probe as prescribed by the test
standard used for appliance certication. 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.
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).

4. An IFT-ECM reset is required if the module is in a
lock-out condition. When this occurs, the appliance
is shut down and the IFT-ECM status indicator LED
will be blinking a RED/GREEN error code along with a
one-time audible double- beep. If the IFT-ECM is in a
lock-out condition, refer to the troubleshooting chart to
interpret the error code and take corrective action as
required. To reset the IFT-ECM after a lock-out error:
CAUTION! Risk of burns! Appliance surfaces are hot
when operating and during cool down. Use care and
wear gloves when opening the front and accessing com-
ponents inside the appliance.
- Be aware the appliance may be HOT, use
care in accessing the IFT-ECM.
- Set the IFT-ECM 3-position selector switch to
OFF position.
1. The Electronic Control Module (IFT-ECM) has a
three-position ON/OFF/REMOTE selector switch
that must be set for proper operation. See Figure
3.5. When changing switch positions, it is important
to pause in each position for 1-2 seconds.
OFF Position:
The appliance will not respond to any commands
from a wired wall switch, IFT-RC150 or IFT-RC400
remote controls. The unit should be in the OFF
position during service, fuel conversion, and to

55 Frequently Asked Questions and Troubleshooting
A. Frequently Asked Questions
Contact your dealer for additional information regarding operation and troubleshooting. Visit www.heatilator.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.
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 off 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 affect 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 off when appliance is
turned off. Some optional control systems available with IPI models may allow pilot ame to
remain lit.
Power Outages
(battery backup)
NBV-IFT appliances are not approved for use with battery backup. Do NOT operate
this appliance with battery backup. This appliance will not be protected by the high
temp limit switch if battery backup is installed. 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

the remote, the ame intensity will automatically decrease. Au-
tomatic ame modulation will result in more control of the tem-
perature, and will cause the appliance to cycle OFF/ON less.
The appliance turns OFF the ame
after extended periods of operation 9 hour safety shutdown timer
This is normal behavior. The appliance has a safety timer that
will automatically turn OFF the ame after nine hours of
uninterrupted operation.
The remote displays the following

Call dealer to have them program the remote with correct
branding. Remote is still fully functional and the appliance is
unaffected.
After turning ame ON using
remote, the ame does not turn
ON immediately and instead a two
minute timer is displayed.
Power vent is installed on the
appliance.
This is expected behavior and the two minute timer is called a
pre-purge timer. The ame will turn ON at the expiration of the
timer.
The remote displays the following
message on-screen:
“Remote Control Communication
Error.”
No power to appliance. Verify home circuit breaker is on and master reset is on (if
equipped).
The remote displays the following
message on -screen: Sorry your
appliance did not start. Try again
by pressing Flame On.
No power to appliance. No gas
to appliance. Accumulation
of air in gas line from extended
period of appliance inactivity.
