Getting Started
A. Design and Installation Considerations
Heat & Glo 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.
CAUTION
Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building, fi re offi cials or
authorities having jurisdiction about restrictions, installation
inspection, and permits.
When planning an appliance installation, it’s necessary to
determine the following information before installing:
• Where the appliance is to be installed. See Section 3.
• Gas supply piping. See Section 6.
B. Tools and Supplies Needed
Before beginning the installation be sure that the following
tools and building supplies are available.
Reciprocating saw Framing material
Pliers Hi temp caulking material
Hammer Gloves
Phillips screwdriver Framing square
Flat blade screwdriver Electric drill and bits (1/4 in.)
Plumb line Safety glasses
Manometer Voltmeter
Tape measure Level
Non-corrosive leak check solution
1/2 - 3/4 inch length, #6 or #8 Self-drilling screws
One 1/4 inch female connection (for optional fan)
C. Inspect Appliance and Components
WARNING
Inspect appliance and components for damage.
Damaged parts may impair safe operation.
• Do NOT install damaged components.
• Do NOT install incomplete components.

C. After Appliance is Lit
Initial Break-in Procedure
When you light the appliance, you may notice that it produces heat which does have an associated odor or smell.
If you feel this odor is excessive it may require the initial
three to four hour continuous burn on high followed by a
second burn up to 12 hours to fully drive off any odor from
paint and lubricants used in the manufacturing process.
Condensation of the glass is normal.
NOTE: The appliance should be run three to four hours
on the initial start-up. Turn it off and let it cool completely.
Remove and clean the glass. Replace the glass and run
the appliance for an additional 12 hours. This will help to
cure the products used in the paint and logs.
During this break-in period it is recommended that some
windows in the house be opened for air circulation. This will
help avoid setting off smoke detectors, and help eliminate
any odors associated with the appliance’s initial burning.
WARNING
Fire Risk.
High Temperatures.
Keep combustible household items away from
appliance.
Do NOT obstruct combustion and ventilation air.
• Do NOT place combustible items on top of or
in front of appliance.
• Keep furniture, draperies away from
appliance.
CAUTION
• Prevent accidental appliance operation when not
attended.
• Unplug or remove batteries from remote control if absent
or if appliance will not be used for an extended period of
time.
• Property damage possible from elevated temperatures.
CAUTION
Smoke and odors released during initial operation.
• Open windows for air circulation.
• Leave room during initial operation.
• Smoke may set off smoke detectors.
Smoke and odors may be irritating to sensitive
individuals.
WARNING
Fire Hazard.
Keep combustible materials, gasoline and
other fl ammable vapors and liquids clear of
appliance.
• Do NOT store fl ammable materials in the
appliance’s vicinity.
• Do NOT use gasoline, lantern fuel, kerosene,

D. Frequently Asked Questions
ISSUE SOLUTIONS
Condensation of the glass
Blue fl ames
Odor from appliance
Film on the glass
Metallic noise
Is it normal to see the pilot fl ame burn
continually?
This is a result of gas combustion and temperature variations. As the appliance warms, this
condensation will disappear.
This is a result of normal operation and the fl ames will begin to yellow as the appliance is al-
lowed to burn for 20 to 40 minutes.
When fi rst operated, this appliance may release an odor for the fi 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 fi nishing materials and adhesives used around the
appliance.
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
process. A non-abrasive cleaner such as gas fi replace 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 appliance.
In an Intellifi re ignition system it is normal to see the pilot fl ame, but it should turn off when
ON/OFF is turned off. In a standing pilot system the pilot will always stay on.

Troubleshooting
With proper installation, operation, and maintenance your gas appliance will provide years of trouble-free service. If you do
experience a problem, this troubleshooting guide will assist a qualifi ed service person in the diagnosis of a problem and the
corrective action to be taken. This troubleshooting guide can only be used by a qualifi ed service technician.
A. Intellifi re Ignition System
Sympton Possible Cause Corrective Action
1. The ignitor/module
makes noise, but no
spark.
a. Incorrect wiring. Verify “S” wire (white) for sensor and “I” wire (orange) for ignitor are connected to
correct terminals on module and pilot assembly. Reversed wires at the module may
cause system to make sparking noise, but spark may not be present at pilot hood.
2. Pilot won’t light,
there is no noise or
spark.
3. Pilot lights but
continues to spark,
and main burner will
not ignite. (If the pilot
continues to spark
after the pilot fl ame
has been lit, fl ame
rectifi cation has not
occurred.)
b. Loose connections
or electrical shorts in
the wiring.
c. Ignitor gap is too
large.
d. Faulty module. Turn ON/OFF rocker switch or wall switch to OFF position. Remove ignitor wire
a. Transformer
installed correctly.
b. A shorted or loose
connection in wiring
confi guration or wiring
harness.
c. Improper wall switch
wiring.
d. Module not
grounded.
e. Faulty module. Turn ON/OFF rocker switch or wall switch to OFF position. Remove ignitor wire
a. A shorted or loose
connection in sensor
rod.
b. Poor fl ame rectifi -
cation or contaminated
sensor rod.
c. Module is not
grounded.
Verify no loose connections or electrical shorts in wiring from module to pilot assembly. Rod closest to pilot hood should be ignitor. Verify connections underneath pilot
assembly are tight; also verify connections are not grounding out to metal chassis,
pilot burner, pilot enclosure, mesh screen if present, or any other metal object.
Verify gap of igniter to pilot hood. The gap should be approximately .17 inch or 1/8
inch.
“I” from module. Place ON/OFF Rocker switch or wall switch in ON position. Hold
ground wire about 3/16 inch away from “I” terminal on module. 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.
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. Remove and verify continuity of each
wire in wiring harness.
Verify that 110/VAC power is “ON” to junction box.
Verify black ground wire from module wire harness is grounded to metal chassis of
appliance.
“I” from module. Place ON/OFF Rocker switch or wall switch in ON position. Hold
ground wire about 3/16 inch away from “I” terminal on module. 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.
Verify all connections to wiring diagram in manual. Verify connections underneath
pilot assembly are tight. Verify connections are not grounding out to metal chassis,
pilot burner, pilot enclosure or screen if present, or any other metal object.
Verify that fl ame is engulfi ng sensor rod. If the pilot assembly does not have a
ground strap, consider installing one to increase fl ame rectifi cation. Verify correct pi-
lot orifi ce is installed and inlet gas specifi cations. Flame carries rectifi cation current,
not the gas. If fl ame lifts from pilot hood, the circuit is broken. A wrong orifi ce or too
high an inlet pressure can cause pilot fl ame to lift. The sensor rod may be contami-
nated. Clean sensor rod with emery cloth.
Verify that module is securely grounded to metal chassis of appliance. Verify that
wire harness is fi rmly connected to module.
