(in the United States), or to the CSA C22.1 Canadian Electric
Code (in Canada).
High Altitude Installations
U.L. Listed gas fireplaces are tested and approved for
elevations from 0 to 2,000 feet in the U.S.A. and from 0 to
4,500 feet in Canada.
When installing this fireplace at an elevation above 2,000
feet (in the United States), it may be necessary to decrease
the input rating by changing the existing burner orifice to a
smaller size. Input should be reduced four percent (4%) for
each 1,000 feet above sea level, unless the heating value of
the gas has been reduced, in which case this general rule
will not apply.
When installing this fireplace at an elevation between 2,000
and 4,500 feet (in Canada), the input rating must be reduced
by ten percent (10%).
When installing this fireplace at an elevation above 4,500

PIER-38HV
Constructing the Fireplace Chase
A chase is a vertical box-like structure built to enclose the
gas fireplace and/or its vent system. Vertical vents that run
on the outside of a building may be, but are not required to
be, installed inside a chase.
CAUTION: TREATMENT OF FIRESTOP SPACERS AND
CONSTRUCTION OF THE CHASE MAY VARY WITH THE
TYPE OF BUILDING. THESE INSTRUCTIONS ARE NOT
SUBSTITUTES FOR THE REQUIREMENTS OF LOCAL
BUILDING CODES. THEREFORE, YOUR LOCAL BUILDING CODES MUST BE CHECKED TO DETERMINE THE
REQUIREMENTS FOR THESE STEPS.
Factory-built fireplace chases should be constructed in the
manner of all outside walls of the home to prevent cold air
drafting problems. The chase should not break the outside
building envelope in any manner.
This means that the walls, ceiling, base plate and cantilever
floor of the chase should be insulated. Vapor and air infiltration barriers should be installed in the chase as per regional
codes for the rest of the home. Additionally, Heat-N-Glo recommends that the inside surfaces be sheetrocked and taped
for maximum air tightness.
To further prevent drafts, the firestops should be caulked to
seal gaps. Gas line holes and other openings should be
caulked or stuffed with insulation. If the unit is being installed on a cement slab, we recommend that a layer of
plywood be placed underneath to prevent conducting cold
up into the room. Be sure to include spark arrestors for
woodburning units if they are required.

Step 3. Installing the Vent System
A. Vent System Approvals
These models are approved to use SL-series direct
vent pipe components and terminations. Approved
vent system components are labeled for identification. This pipe is tested and listed as an approved
component of the fireplace. The pipe is tested to be
run inside an enclosed wall. There is no requirement
for inspection openings at each joint within the wall.
There is no required pitch for horizontal vent runs.
NO OTHER VENTING SYSTEMS OR COMPONENTS MAY BE USED.
Detailed installation instructions are included with each
vent termination kit and should be used in conjunction
with this Installers Guide. The drawing below shows
vent system components and terminations.

For Vertical Terminations - To locate the vent and
install the vent sections:
Locate and mark the vent centerpoint on the underside
of the roof, and drive a nail through the centerpoint.
Make the outline of the roof hole around the centerpoint
nail.
The size of the roof hole framing dimensions depend on the
pitch of the roof. There MUST BE a 1-inch (25.4mm) clearance from the vertical vent pipe to combustible materials.
Mark the roof hole accordingly.
Cover the opening of the installed vent pipes.
Cut and frame the roof hole.
To seal the roof hole, and to divert rain and snow from the
vent system:
Attach a flashing to the roof using nails, and use a non-
hardening mastic around the edges of the flashing base
where it meets the roof.
Attach a storm collar over the flashing joint to form a
water-tight seal. Place non-hardening mastic around the
joint, between the storm collar and the vertical pipe.
Slide the termination cap over the end of the vent pipe
and rotate the pipe clockwise 1/4 turn.
HORIZONTAL
OVERHANG
Use framing lumber the same size as the roof rafters
and install the frame securely. Flashing anchored to the
frame must withstand heavy winds.
Continue to install concentric vent sections up through
the roof hole (for inside vent installations) or up past the
roof line until you reach the appropriate distance above
the roof (for outside terminations).

Step 6. 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.
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 (13mm)
hook-up at the unit.
This gas fireplace is designed to accept a 1/2 inch (13mm)
gas supply line.
To install the gas supply line:
A listed (and State 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 substituting
for these components, please consult local codes for
compliance.
Locate the gas line access hole in the outer casing of
the fireplace.
The gap between the supply piping and gas access hole
can be plugged with non-combustible insulation to prevent cold air infiltration.
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.

Hearth Extensions
A hearth extension may be desirable for aesthetic reasons.
However, ANSI or CAN/CGA testing standards do not require
hearth extensions for gas fireplace appliances.
Step 10. Installing Trim, Logs & Ember Material
Installing the Trim
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 raised and the trim door removed.
Positioning the Logs
The gas logs have been factory installed and should not
need to be positioned. After removing the stretch wrapping,
reinstall the logs and grate (see Figure 37). Make sure the
end of the grate with the incomplete cross bar is on the
pilot end of the firebox.
If sooting occurs, the logs might need to be repositioned
slightly to avoid excessive flame impingement.

ST-38HV 34 X 20 N/A TEMPERED
Heat-N-Glo 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 requirements of ANSI
Z97.1-1984 and CPSC 16 CFR 1202. (Safety Glazing
Certification Council SGCC # 1595 and 1597. Architectural
Testing, Inc. Reports 02-31919.01 and 02-31917.01.)
This statement is in compliance with CPSC 16 CFR Section
1201.5 Certification and labeling requirements which refers
to 15 USC 2063 stating Such certificate shall accompany
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 contact
your dealer or distributor to order.
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 chemicals
used in the paint and logs.
Step 12. Lighting the Fireplace
Youve reviewed all safety warnings, youve checked the
fireplace for gas leaks, you know the vent system is
unobstructed, and youve checked for faulty components.
Now youre ready to light the fireplace.
Step 11. 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 terminations 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 is DANGEROUS and voids all warranties.

Fireplace Maintenance
Although the frequency of your fireplace servicing and maintenance will depend on use and the type of installation, you
should have a qualified service technician perform an appliance 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 Golden Ember (DE-93) and Glowing Ember (050-
721). New ember material should be placed alternately on
top of the burner - a layer of Golden Ember, a layer of
Glowing Ember, and so on. 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.
Checking Flame Patterns, Flame Height
Frequency: Periodically.
By: Qualified service technician/Home owner.
Task: Make a visual check of your fireplaces flame patterns.
Figure 39.
Burner Flame Patterns
Make sure the flames are steady - not lifting or floating.
See Figure 39. The flame sensor (DSI) or thermopile/
thermocouple (standing pilot) tips should be covered with
flame. See Figures 28 and 29.
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 cap 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, particularly 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.
