or service this insert.
• Any change to this insert or its controls can be dangerous.
• Improper installation or use of this insert can cause serious injury or death from fire,
burns, explosions, electrical shock and carbon monoxide poisoning.
• Improper installation, adjustment, alteration, services or maintenance can cause injury
or property damage. Refer to this manual. For assistance or additional information
consult a qualified installer, service agency or the gas supplier.
• DUE TO HIGH TEMPERATURES, THE APPLIANCE SHOULD BE LOCATED OUT OF
TRAFFIC AND AWAY FROM FURNITURE AND DRAPERIES.
• CHILDREN AND ADULTS SHOULD BE ALERTED TO THE HAZARDS OF HIGH
WARNINGS
SURFACE TEMPERATURE AND SHOULD STAY AWAY TO AVOID BURNS OR CLOTHING

This insert is a vented product. This insert must be properly
installed by a qualified service person. The glass door must be
properly seated and sealed. If this unit is not properly installed
by a qualified service person with glass door properly seated
and sealed, combustion leakage can occur.
CARBON MONOXIDE POISONING: Early signs of
carbon monoxide poisoning are similar to the flu with headaches, dizziness and/or nausea. If you have these signs, the
insert may not have been installed properly. Get fresh air at
once! Have the insert inspected and serviced by a qualified
service person. Some people are more affected by carbon
monoxide than others. These include pregnant women, people
with heart or lung disease or anemia, those under the influence
of alcohol, and those at high altitudes.
Propane/LP gas and natural gas are both odorless. An odormaking agent is added to each of these gases. The odor helps
you detect a gas leak. However, the odor added to these gases
can fade. Gas may be present even though no odor exists.
Make certain you read and understand all warnings. Keep this
manual for reference. It is your guide to the safe and proper
operation of this insert.

2. For propane/LP insert, do not place propane/LP supply
tank(s) inside any structure. Locate propane/LP supply
tank(s) outdoors. To prevent performance problems, do not
use propane/LP fuel tank of less than 100 lbs. capacity.
3. If you smell gas
• shut off gas supply.
• do not try to light any appliance.
• do not touch any electrical switch; do not use any
phone in your building .

The following factors should be taken into consideration:
• This insert should have sufficient access for its safe operation and maintenance.
• The flow of combustion and ventilation air must not be obstructed.
• Minimum clearances to combustibles, such as mantels,
• Never obstruct the front opening of the insert.
• Do
• These units can be installed in a bedroom. See National Fuel Gas Code ANSI Z233.1/NFPA 54 (current edition), the

not install in the vicinity where gasoline or other flammable liquids may be stored.
Uniform Mechanical Code (current edition), and Local Building Codes for specific installation requirements.
The location and clearances are subject to local building codes.
INSERT APPLICATIONS
Before installing the gas fireplace insert, consider the functioning needs of the fireplace. Confirm the size of the fireplace
cavity, the design of the chimney, and the availablility of the gas supply and electricity for the insert fan.
IMPORTANT: Your direct vent insert is designed to be only vented vertically with a minimum height of
10 feet.
When the unit is installed into a woodburning fireplace, the minimum distance the mantel can be placed above the fireplace is
governed by local building codes applicable to woodburning fireplaces. Consult local authorities having jurisdiction for these
clearances. The underside of the mantel will become warm. Use only finishes which are heat resistant and do not discolor.
must be maintained. See Figures 3 and 4, pages 9 and 10.
CLEARANCES
MINIMUM FIREPLACE SIZE/CLEARANCES TO COMBUSTIBLES
The dimensions shown in Figures 4 and 5, pages 9 and 10, are minimum clearances to
maintain when installing this heater. Follow these instructions carefully to ensure safe
installation. Failure to follow instructions exactly can create a fire hazard.
WARNING
Maintain the following minimum clearances for service and maintenance. See pages 9 and 10.

INSERT CLEARANCES
No combustibles (ie: drapes, doors) may be within, or swing within, 36" of the front of the inset.
INSTALLATION
Figure 3 - Mantel Clearances
MANTEL CLEARANCES
NOTE: The combustible area above the facing must not protrude more than 3/4" from the facing. If it
does, it is considered a mantel and must meet the mantel requirements shown above.
HEARTH REQUIREMENTS
The insert must be installed on a non-combustible hearth extending a minimum of 12" from the fireplace opening (local
codes may require a larger hearth). The hearth must also extend to both sides of the face (see the table on page 7).
57D0016 9
INSTALLATION
INSERT PLACEMENT
• Insert must be placed within a code-conforming masonry fireplace or a tested and listed zero-clearance (UL-127, solid
fuel) fireplace. Repair any fireplace damage prior to installation.
• Because the insert uses a circulation blower, clean the fireplace, smoke shelf, and chimney before installing.
• This heater may be placed in a bedroom. Please be aware of the large amount of heat this appliance produces when
determining a location.
For tight fits you may remove the manifold.
See “Removing the Mainfold,” page 16.

INSTALLATION
ZERO-CLEARANCE (METAL) FIREPLACE REQUIREMENTS
• The damper and grate must be removed.
• The smoke shelf, internal baffles, screen, refractory, and metal or glass doors may be removed (if applicable).
• Installer must attach red warning plate to the inside of the firebox of fireplace with
screws supplied.
• Do not cut any sheet metal parts of the fireplace in which this gas fireplace insert is
installed. THIS IS STRICTLY PROHIBITED!
• If factory-built fireplace has no gas access hole(s) provided, drill a 1.5" (37.5mm) or
less through lower sides or bottom of firebox. You must plug the access hole with
WARNING
noncombustible insulation after gas supply line has been installed.
• If your factory-built fireplace has air passages on the face for zero capabilities, DO
NOT BLOCK THESE PASSAGES!
• Do not remove or alter the insulation or any structured rigid frame members (metal sides, floor, door frame, face of the
fireplace, etc.).
Figure 5 - Metal Fireplace Zero-Clearance Requirements
IMPORTANT:Please review the following carefully.
It is normal for inserts fabricated of steel to give off some expansion and/or contraction noises during the start up or cool
down cycle. Similar noises are found with your furnace heat exchanger or car engine.
It is not unusual for your insert to give off some odor the first time it is burned. This is due to the curing of the paint and any
undetected oil from the manufacturing process.
Please ensure that your room is well-ventilated. OPEN ALL WINDOWS DURING INITIAL BURN OFF/
CURING PHASE.
Burn your insert for a least six (6) hours on “HIGH” the first time you use it. Place fan in the “OFF” position during
this time.
57D0016 11
VENT INSTALLATION
Read all instructions completely and thoroughly before attempting installation. Failure
to do so could result in serious injury, property damage or loss of life. Operation of
improperly installed and maintained venting systems could result in serious injury,
property damage or loss of life.
WARNING
Failure to follow these instructions will
void the warranty.
NOTICE
INSTALLATION PRECAUTIONS
Consult local building codes before beginning the installation. The installer must make sure to select the proper vent system
for installation. Before installing vent kit, the installer must read this insert manual and vent kit instructions.
Only a qualified installer/service person should install venting system. The installer must follow these safety rules:
• Wear gloves and safety glasses for protection.
• Use extreme caution when using ladders or when on rooftops.
• Be aware of electrical wiring locations in walls and ceilings.
The following actions will void the warranty on your venting system:
• Installation of any damaged venting component.
• Unauthorized modification of the venting system.
• Installation of any component part not manufactured or approved by Monessen.
• Installation other than permitted by these instructions.
This insert must be vented to the outside. The venting system must NEVER be attached
to a chimney serving a separate solid fuel burning appliance. Each gas appliance must
use a separate vent system. Do not use common vent systems.
