K. Frequently Asked Questions
ISSUE SOLUTIONS
Condensation on the glass
Blue fl ames
Odor from fi replace
Film on the glass
Metallic noise
This is a result of gas combustion and temperature variations. As the fi replace warms, this
condensation will disappear.
This is a result of normal operation and the fl ames will begin to yellow as the fi replace is al-
lowed to burn for 20 to 40 minutes.
When fi rst operated, this fi replace may release an odor for the fi rst several hours. This is
caused by the curing of materials from manufacturing. Odor may also be released from fi nish-
ing materials and adhesives used near the fi replace. These circumstances may require ad-
ditional curing related to the installation environment.
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.
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 fi replace.

Getting Started
Installer Guide
A. Design and Installation Considerations
Heat & Glo LifeStyle direct vent gas appliances are designed to operate with all combustion air siphoned from
outside of the building and all exhaust gases expelled to
the outside. No additional outside air source is required.
The Twilight-II-B has been carefully engineered to provide a unique fi replace 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 fl ashing and sealing in-
structions.
2. In the cold northern climates pay attention to exposures 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
quality window system. T emperatures near the appliance 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, fi re offi cials 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 fi nishing details.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualifi ed
service technician, service agency or your dealer.
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).
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 benefi t.

mm) away from “I” terminal on module. Place ON/OFF rocker switch
or wall switch in ON position. If there is no spark at “I” terminal module
must be replaced. If there is a spark at “I” terminal, module is fi ne.
Inspect pilot assembly for shorted sparker wire or cracked insulator
around electrode. Replace pilot if necessary .
Verify that transformer is installed and plugged into module. Check
voltage of transformer under load at spade connection on module
with ON/OFF switch in ON position. Acceptable readings of a good
transformer are between 3.2 and 2.8 volts AC.
Remove and reinstall the wiring harness that plugs into module.
Verify there is a tight fi t. Verify pilot assembly wiring to module. Re-
move and verify continuity of each wire in wiring harness. Replace
any damaged components.
3. Pilot sparks, but
Pilot will not light.
C. Improper wall switch wiring. Verify that 110/VAC power is “ON” to junction box.
D. Module not grounded. Verify black ground wire from module wire harness is grounded to
metal chassis of appliance.
E. Module. Turn ON/OFF rocker switch or wall switch to OFF position. Remove
ignitor wire “I” from module. Place ON/OFF rocker switch or wall
switch in ON position. If there is no spark at “I” terminal module
must be replaced. If there is a spark at “I” terminal, module is fi ne.
Inspect pilot assembly for shorted sparker wire or cracked insulator
around electrode.
A. Gas supply. Verify that incoming gas line ball valve is “open”. Verify that inlet
pressure reading is within acceptable limits, inlet pressure must not
exceed 14 in. W.C.
B. Ignitor gap is too large. Verify gap of igniter to right side of pilot hood. The gap should be
approximately .17 in. or 1/8 in. (3 mm).
C. Module is not grounded. Verify module is securely grounded to metal chassis of appliance.
