• The fireplace should be run three to four hours continu-
ously on high.
• Turn the fireplace off and allow it to completely cool.
• Remove fixed glass assembly. See Section 11.G.
• Clean fixed glass assembly. See Section 3.
• Replace the fixed glass assembly and run continuously
on high an additional 12 hours.

place break-in.
• Some people may be sensitive to smoke and odors.
• Smoke detectors may activate.
J. After Fireplace is Lit
K. Frequently Asked Questions
ISSUE SOLUTIONS
Condensation on the glass This is a result of gas combustion and temperature variations. As the fireplace warms, this
condensation will disappear.
Blue flames This is a result of normal operation and the flames will begin to yellow as the fireplace is al-
lowed to burn for 20 to 40 minutes.
Odor from fireplace
When first operated, this fireplace may release an odor for the first several hours. This is
caused by the curing of materials from manufacturing. Odor may also be released from finish-
ing materials and adhesives used near the fireplace. These circumstances may require ad-
ditional 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. A non-abrasive cleaner such as gas appliance glass
cleaner may be necessary. See 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 fireplace.
Is it normal to see the pilot flame burn
continually?
In an intermittent pilot ignition system (IPI), the pilot flame should turn off when appliance is
turned off. Some optional control systems available with IPI models may allow pilot flame to
remain lit.

A. Design and Installation Considerations
Hearth & Home Technologies direct vent gas appliances
are designed to operate with all combustion air siphoned
from outside of the building and all exhaust gases ex-
pelled to the outside. No additional outside air source is
required.
The Twilight-II-B has been carefully engineered to pro-
vide a unique fireplace experience. Since it is different
than any other product on the market, care must be taken
when installing this appliance so that our customer does
not experience undesirable performance or conditions.
1. Install the appliance according to this Owner’s Guide
paying particular attention to flashing and sealing in-
structions.
2. In the cold northern climates pay attention to expo-
sures and prevailing wind conditions when locating the
appliance, the same as you would for locating exterior
windows and doors.
The Twilight-II-B has the thermal characteristics of a high
qualitywindowsystem.Temperaturesneartheappliancewill
be cooler than what is realized with a fully insulated wall.
Operation of the appliance will eliminate any cool drafts
and will provide the room with a comfortable ambiance.
Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector, fire officials or authorities having
jurisdiction over restrictions, installation inspection and
permits.
Before installing, determine the following:
• Where the appliance is to be installed.
• Gas supply piping requirements.
• Electrical wiring requirements.
• Framing and finishing details.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
C. Inspect Appliance and Components
• Carefully remove the appliance and components from
the packaging.
• The vent system components and decorative doors and
fronts may be shipped in separate packages.
• If packaged separately, the log set and appliance grate
must be installed.
• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
•Read all of the instructions before starting the instal-
lation. Follow these instructions carefully during the
installation to ensure maximum safety and benefit.
WARNING! Risk of Fire or Explosion! Damaged parts
could impair safe operation. DO NOT install damaged, in-
complete or substitute components. Keep appliance dry.
B. Tools and Supplies Needed
Before beginning the installation be sure that the following
tools and building supplies are available.
