12 Outdoor Lifestyles by Hearth & Home Technologies, Inc. • TWILIGHT-II-MOD • 2290-900 Rev. C • 7/12
Initial Break-in Procedure
• 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.F.
• Clean fixed glass assembly. See Section 3.
• Replace the fixed glass assembly and run continuously
on high an additional 12 hours.
This cures the materials used to manufacture the fire-
place.
NOTICE! Open windows for air circulation during fire-
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. 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.
Glass Rock Media Kit
There may be some “cracking” noise coming from the fireplace during the first few heating
and cooling cycles. This noise is associated with settling rock and some minor cracking of
larger pieces of rock. This will lessen over time as the glass rock is conditioned to the heat-
ing and cooling temperature changes.
It is expected that a few small pieces (approximately 10 pieces) of rock may fall through the
base pan and come to rest on the fireplace bottom. This has no affect on fireplace perfor-
mance.
Glass Rock Media Color Change It is normal for the glass rock media to change color slightly over the lifetime of the
appliance.
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-MOD has been carefully engineered to
provide 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-MOD has the thermal characteristics of a
high quality window system. Temperatures near the appli-
ance will 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 decorative doors and fronts may be shipped in
separate packages.
• 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.
Tape measure Framing material
Pliers High temperature caulking material
Hammer Phillips screwdriver
Gloves Framing square
Voltmeter Electric drill and bits (1/4 in.)
Plumb line Safety glasses
Level Reciprocating saw
Manometer Flat blade screwdriver
Non-corrosive leak check solution
1/2 - 3/4 in. length, #6 or #8 Self-drilling screws
One 1/4 in. female connection (for optional fan).
Hearth&HomeTechnologies disclaims any responsibilityfor,
and the warranty will be voided by, the following actions:
• Installation and use of any damaged appliance or vent
system component.
• Modification of the appliance or vent system.
• Installation other than as instructed by Hearth & Home
Technologies.
• Improper positioning of the gas logs or the glass door.
• Installationand/oruseofanycomponentpartnotapproved
by Hearth & Home Technologies.
Any such action may cause a fire hazard.
WARNING! Risk of Fire, Explosion or Electric Shock!
DO NOT use this appliance if any part has been under
water. Call a qualified service technician to inspect the
appliance and to replace any part of the control system
and/or gas control which has been under water.
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualified
service technician, service agency or your dealer.
