Approvals and
Codes
Installation Codes
Thefireplace installationmust conformto localcodes. Before
installing the fireplace, consult the local building code
agency to ensure that you are in compliance with all
applicable codes, including permits and inspections.
In the absence of local codes, the fireplace installation must
conform to the National Fuel Gas Code ANSI Z223.1 (in
the United States) or the CAN/CGA-B149 Installation Codes
(in Canada). The appliance must be electrically grounded
in accordance with local codes or, in the absence of local
codes with the National Electric Code ANSI/NFPA No. 70
(inthe UnitedStates), orto the CSAC22.1 Canadian Electric
Code (in Canada).
These models may be installed in a bedroom or bed-sitting
room in the U.S.A. and Canada.
High Altitude Installations
U.L. Listed gas appliances are tested and approved with-
out requiring changes for elevations from 0 to 2,000 feet in
the U. S. A. and in Canada.
When installing this appliance at an elevation above 2,000
feet, it may be necessary to decrease the input rating by
changing the existing burner orifice to a smaller size. Input
rate should be reduced by 4% for each 1000 feet above a
2000 foot elevation in the U.S.A. or 10% for elevations
between 2000 and 4500 feet in Canada. If the heating value
of the gas has been reduced, these rules do not apply. To
identify the proper orifice size, check with the local gas
utility.
If installing this appliance at an elevation above 4,500 feet
(in Canada), check with local authorities.
The Twilight 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 fireplace so that our customer does not
experience undesirable performance or conditions.
1. Install the fireplace according to this Installer’s Guide
paying particular attention to flashing and sealing
instructions.
2. In the cold northern climates pay attention to exposures
and prevailing wind conditions when locating the fireplace,
the same as you would for locating exterior windows
and doors.
The Twilight has the thermal characteristics of a high quality
window system. Temperatures near the fireplace will be
cooler than what is realized with a fully insulated wall.
Operation of the fireplace will eliminate any cool drafts and
will provide the room with a comfortable ambiance.

Getting Started
Introducing the Heat-N-Glo Lifestyle
Products Gas Fireplaces
Heat-N-Glo Lifestyle Products direct vent gas fireplaces are
designed to operate with all combustion air siphoned from
outside of the building and all exhaust gases expelled to
the outside.
The information contained in this Installers Guide, unless
noted otherwise, applies to all models and gas control
systems. Gas fireplace diagrams, including the dimensions,
are shown in this section.
Pre-install Preparation
This gas fireplace and its components are tested and safe
when installed in accordance with this Installers Guide.
Report to your dealer any parts damaged in shipment,
particularly the condition of the glass. Do not install any
unit with damaged, incomplete, or substitute parts.
Read all of the instructions before starting the
installation. Follow these instructions carefully during
the installation to ensure maximum safety and benefit.
Failure to follow these instructions will void the
owner’s warranty and may present a fire hazard.
The Heat-N-Glo Lifestyle Products Warranty will be voided
by, and Heat-N-Glo Lifestyle Products disclaims any
responsibility for, the following actions:
•Installation of any damaged fireplace.
•Modification of the fireplace vent system.
•Installation other than as instructed by Heat-N-Glo
Lifestyle Products.
•Improper positioning of the gas logs or the glass door.
•Installation and/or use of any component part not manu-
factured and approved by Heat-N-Glo Lifestyle Products,
not withstanding any independent testing laboratory or
other party approval of such component part or acces-
sory.
ANY SUCH ACTION MAY POSSIBLY CAUSE A FIRE
HAZARD.
When planning a fireplace installation, it’s necessary to
determine:
•Where the unit is to be installed.
•Gas supply piping.
•Electrical wiring.
•Framing and finishing details.
•Whether optional accessories—devices such as a wall
switch or remote control—are desired.
If the fireplace is to be installed on carpeting or tile, or on
any combustible material other than wood flooring, the
fireplace should be installed on a metal or wood panel that
extends the full width and depth of the fireplace.

Clearance Requirements
The top and sides of the fireplace are defined by stand-offs.
Theminimum clearanceforthe indoorsideto aperpendicular
wall extending past the face of the fireplace is one inch (25
mm). The metal ends of the fireplace mayNOT be recessed
into combustible construction.
WARNING: TO PREVENT CONTACT WITH
SAGGING OR LOOSE INSULATION, THE
FIREPLACE MUST NOT BE INSTALLED AGAINST
VAPOR BARRIERS OR EXPOSED INSULATION. LO-
CALIZED OVERHEATING COULD OCCUR AND A
FIRE COULD RESULT.
Step 2. Framing the Fireplace
Fireplace framing can be built before or after the fireplace is
set in place. Framing should be positioned to accommo-
date wall coverings and fireplace facing material. The dia-
gram below shows framing reference dimensions.
CAUTION: MEASURE FIREPLACE DIMENSIONS AND
VERIFY FRAMING METHODS AND WALL COVERING
DETAILS BEFORE FRAMING.
*The clearance to the ceiling is measured from the top
of the unit, excluding the standoffs (see Figure 9).
The distance from the unit to combustible construction is to
be measured from the unit outer wrap surface to the com-
bustible construction, NOT from the screw heads that se-
cure the unit together.

Step 3. Positioning, Leveling, and
Securing the Fireplace
Placing the Protective Metal Hearth Strip
Included with your fireplace you will find a metal flashing
strip measuring approximately 46” x 4”. This strip is used
to provide added protection where the fireplace and outer
structure meet.
•Place a generous bead of silicone caulk into the corner
of the protective hearth strip. Place the metal strip onto
the structure where the outer edge of the fireplace will sit
(see Figure 6).
•Place the fireplace into position. Make sure flashing edges
on the outdoor surround fit up tight to the framing.
The diagram below shows how to properly position, level,
and secure the fireplace. Before the framing or fireplace is
set in place, the cutout should be covered with tar paper or
similar material.
Theoutdoor sideofthe fireplacecontainsedges thatprotrude
beyond the normal envelope of the fireplace. Special care
should be taken to avoid damage to these parts.
Figure 5. Proper Positioning, Leveling, and
Securing of a Fireplace
Figure 6.
Positioning the Metal Strip
•Level the fireplace from side to side and front to back.
•Shim the fireplace with non-combustible material, such
as sheet metal, as necessary.
•Secure the fireplace to the framing byusing nails or screws
through the nailing tabs.
•See Figure 7 for placement of combustible housewrap or
building paper and non-combustible sheathing for the
outside wall. Combustible housewrap or building paper
may be brought over the fireplace flange, but not past
the bend in the flange (see Figure 8).
•Once the fireplace is in place, put protective flashing
corner cover pieces (found in manual bag assembly) over
top corners on outside of unit (see Figure 8). Use sili-
cone caulk to place these pieces over the corners and
secure into place. Make sure enough silicone caulk is
used to make a water tight seal between outdoor sur-
round and corner pieces.

must be tightened and checked for leaks with a commer-
cially-available,non-corrosiveleakchecksolution.Besure
to rinse off all leak check solution following testing.
Step 5. The Gas Supply Line
NOTE: Have the gas supply line installed in accordance
with local building codes by a qualified installer
approved and/or licensed as required by the locality.
(In the Commonwealth of Massachusetts installation
must be performed by a licensed plumber or gas fitter).
NOTE: Before the first firing of the fireplace, the gas
supply line should be purged of any trapped air.
NOTE: Consult local building codes to properly size
the gas supply line leading to the 1/2 inch
(13 mm) hook-up at the unit.
This gas fireplace is designed to accept a 1/2 inch
(13 mm) gas supply line. To install the gas supply line:
•A listed (and Commonwealth of Massachusetts approved)
1/2 inch (13mm) tee-handle manual shut-off valve and a
listed flexible gas connector are connected to the 1/2
inch (13mm) inlet of the control valve. NOTE: If substi-
!
tuting for these components, please consult local codes
for compliance.
•Locate the gas line access hole in the outer casing of
the fireplace.
•The gas line may be run from either side of the fireplace
provided the hole in the outer wrap does not exceed 2” in
diameter and it does not penetrate the actual firebox.
•Open the fireplace lower grille, insert the gas supply line
through the gas line hole, and connect it to the shut-off
valve.
•When attaching the pipe, support the control so that the
lines are not bent or torn.
•After the gas line installation is complete, use a soap
solution to carefully check all gas connections for leaks.
WARNING: DO NOT USE AN OPEN FLAME
TO CHECK FOR GAS LEAKS.

FOR INSIDE:
Combustible materials may be brought up to the specified
clearances on the side and top front edges of the fireplace,
but MUST NEVER overlap onto the front face. The joints
between the finished wall and the fireplace top and sides
can only be sealed with a 300° F. (149° C) minimum sealant.
Install optional marble and brass trim surround kits as
desired. Marble, brass, brick, tile, or other non-combustible
materials can be used to cover up the gap between the
sheet rock and the fireplace.
Do not obstruct or modify the air inlet/outlet grilles. When
overlapping on both sides, leave enough space so that the
bottom grille can be lowered and the trim door removed.
FOR OUTSIDE:
Marble, brick, tile, stone, or other non-combustible materials
can be used to cover up the gap between the facing material
and the fireplace. DO NOT obstruct or modify the air intake
or exhaust.
Positioning the Logs
If the gas logs have been factory installed they should not
need to be positioned. If the logs have been packaged
separately, refer to the instructions that accompany the
logs. Save the log instructions with this manual.
If sooting occurs, the logs might need to be repositioned
slightly to avoid excessive flame impingement.

Placing the Ember Material
Ember material is shipped with this gas fireplace. The bag
labeled Glowing Ember (050-721) is standard glowing em-
ber material.
To place the ember material:
•Remove the wing nuts and glass clips around the glass
door.
•Remove the glass door from the unit.
•Place dime size pieces of ember material about 1/2 inch
apart near port holes in burner top. Do NOT press em-
bers into burner ports. Cover the top of the burner with a
single layer of ember material. For best performance do
NOT place embers on the ports at the rear of the burner.
•Save the remaining ember materials for use during fire-
place servicing. The bag of embers provided is sufficient
for 3 to 5 applications.
•Replace the wing nut, glass clips, and screws.
•Replace the glass door and a front trim door on the unit.
•Hand tighten the wing nut.
Figure 14. Placement of the Ember Material
Step 10. Before Lighting the Fireplace
Before lighting the fireplace, be sure to do the following:
Remove all paperwork from underneath the fireplace.
Review safety warnings and cautions
•Read the Safety and Warning Information section at
the beginning of this Installers Guide.
Double-check for gas leaks
•Before lighting the fireplace, double-check the unit for
possible gas leaks.
Double-check vent terminations and front grilles for
obstructions.
•Before lighting the fireplace, double-check the unit for
possible obstructions that could be blocking the vent ter-
minations or the front grilles.
Double-check for faulty components
•Any component that is found to be faulty MUST BE re-
placed with an approved component. Tampering with the
fireplace components isDANGEROUS and voids all war-
ranties.
A small amount of air will be in the gas supply lines. When
first lighting the fireplace, it will take a few minutes for the
lines to purge themselves of this air. Once the purging is
complete, the fireplace will light and will operate normally.
Subsequent lightings of the fireplace will not require this
purging of air from the gas supply lines, unless the gas
valve has been turned to the OFF position, in which
case the air would have to be purged.
NOTE: The fireplace should be run 3 to 4 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 fireplace for
an additional 8 hours. This will help to cure the products
used in the paint and logs.

Indoor TEMPERED
Heat-N-Glo Lifestyle Products fireplaces manufactured with
tempered glass may be installed in hazardous locations
such as bathtub enclosures as defined by the CPSC. The
tempered glass has been tested and certified to the require-
ments of ANSI Z97.1-1984 and CPSC 16 CFR 1202. (Safety
Glazing Certification Council SGCC # 1595 and 1597. Ar-
chitectural Testing, Inc. Reports 02-31919.01 and 02-
31917.01.)
This statement is in compliance with SPCS 16 CFR Sec-
tion 1201.5 “Certification and labeling requirements” which
refers to 15 USC 2063 stating “…Such certificate shall ac-
company the product or shall otherwise be furnished to any
distributor or retailer to whom the product is delivered.”
Some local building codes require the use of tempered glass
with permanent marking in such locations. Glass meeting
this requirement is available from the factory. Please con-
tact your dealer or distributor to order.
Step 11. Lighting the Fireplace
You’ve reviewed all safety warnings, you’ve checked the
fireplace for gas leaks, you know the vent system is
unobstructed, and you’ve checked for faulty components.
Now you’re ready to light the fireplace.

4Maintaining and Servicing Your Fireplace
Fireplace Maintenance
Although the frequency of your fireplace servicing and main-
tenance will depend on use and the type of installation, you
should have a qualified service technician perform an appli-
ance check-up at the beginning of each heating season.
See the table below for specific guidelines regarding each
fireplace maintenance task.
IMPORTANT: TURN OFF THE GAS BEFORE SERVICING
YOUR FIREPLACE.
Replacing old ember material
Frequency: Once annually, during the checkup.
By: Qualified service technician.
Task: Brush away loose ember material near the burner.
Replace old ember material with new dime-size and shape
pieces of Glowing Ember (050-721). Save the remaining
ember material and repeat this procedure at your next
servicing. For more information, see Placing Ember
Material.
Cleaning Burner and Controls
Frequency: Once annually.
By: Qualified service technician.
Task: Brush or vacuum the control compartment, fireplace
logs and burner areas surrounding the logs.
Cleaning Flame Sensor Rod (IPI Systems)
Frequency: Annually.
By: Qualified service technician.
Task: Make a visual check of the straight flame sensor rod
(see Figure 9). Use emery cloth to carefully remove any
existing film or white deposits.
Checking Flame Patterns, Flame Height
Frequency: Periodically.
By: Qualified service technician/Home owner.
Task: Make a visual check of your fireplace’s flame patterns.
Make sure the flames are steady - not lifting or floating.
See Figure 15. The thermopile/thermocouple tips should
be covered with flame.
Checking Vent System
Frequency: Before initial use and at least annually
thereafter, more frequently if possible.
By: Qualified service technician/Home owner.
Task: Inspect the external vent on a regular basis to ensure
that no debris is interfering with the flow of air. Inspect entire
vent system for proper function.
Cleaning Glass Door
Frequency: After the first 3 to 4 hours of use. As neces-
sary after initial cleaning.
By: Home owner.
Task: Remove and clean glass after the first 3 to 4 hours of
use. After the initial cleaning, clean as necessary, particu-
larly after adding new ember (flame colorant) material. Film
deposits on the inside of the glass door should be cleaned
off using a household glass cleaner.NOTE: DO NOT handle
or attempt to clean the door when it is hot and DO
NOT use abrasive cleaners.
NOTE: Under certain weather conditions, some water may
accumulate inside the fireplace. This is normal and ex-
pected. The control compartment contains two removable
drip pans that may be cleaned as necessary (see Figure
16). Excess moisture can be eliminated by burning the fire-
place for a few hours.
