they are in the same room as the appliance. Toddlers,
young children and others may be susceptible to
accidental contact burns. A physical barrier is recom-
mended if there are at risk individuals in the house. To
restrict access to a replace or stove, install an adjust-
able safety gate to keep toddlers, young children and
other at risk individuals out of the room and away from
hot surfaces.
7. Do not modify insert under any circumstances. Any
parts removed for servicing must be replaced prior to
operating insert.
8. Turn insert off and let cool before servicing, installing,
or repairing. Only a qualied service person should
install, service, or repair the insert. Have burner system
inspected annually by a qualied service person.
9. You must keep control compartments, burners, and

be properly seated and sealed. If this unit is not properly
installed by a qualied 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 u 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 qualied
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 inuence of alcohol, and those at high altitudes.
Propane/LP gas and natural gas are both odorless. An
odor-making agent is added to each of these gases. The

BEFORE YOU START
Read this homeowner manual thoroughly and follow all
instructions carefully. Inspect all contents for shipping
damage and immediately inform your dealer if any damage
is found. Do not install any unit with damaged, incomplete,
or substitute parts. Check your packing list to verify that all
listed parts have been received.
INSTALLATION PLANNING
Plan for the installation of your insert. This includes deter-
mining the size of replace in which unit is to be installed,
length of venting to be used and nishing details, and
whether any optional accessories (i.e. wall switch, or
remote control) are desired. Consult your local building
code agency to ensure compliance with local codes,
including permits and inspections.
The following factors should be taken into consideration:
• This insert should have sufcient access for its safe
operation and maintenance.
•The ow of combustion and ventilation air must not be
obstructed.
•Minimum clearances to combustibles, such as mantels,
must be maintained. Refer to Pages 8 and 9, Figures 4
and 5.
•Never obstruct the front opening of the insert.
•Do not install in the vicinity where gasoline or other
ammable liquids may be stored.
•These units can be installed in a bedroom. Refer to
National Fuel Gas Code ANSI Z233.1/NFPA 54 (current
edition), the Uniform Mechanical Code (current edi-
tion), and Local Building Codes for specic installation
requirements.
IMPORTANT: Your direct vent insert was designed to
be installed in an existing wood burning replace. The
location and clearances are subject to local building
codes.
PRE-INSTALLATION INFORMATION
INSERT APPLICATIONS
Before installing the gas replace insert, consider the
functioning needs of the replace. Conrm the size of the
replace cavity, the design of the chimney, and the avail-
ability 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 wood burning replace,
the minimum distance the mantel can be placed above the
replace is governed by local building codes applicable to
wood burning replaces. Consult local authorities having
jurisdiction for these clearances. The underside of the
mantel will become warm. Use only nishes which are heat
resistant and do not discolor.

INSTALLATION ITEMS NEEDED
Make sure you have the items listed below before install-
ing appliance.
•External regulator (supplied by installer)
•Piping (check local codes)
•Test gauge connection*
•Sealant (resistant to propane/LP gas)
•Sediment trap (optional but recommended)
•Tee joint
•Pipe wrench
• Approved exible gas line with gas connector (if al-
lowed by local codes — not provided)
* A CSA design-certied equipment shutoff valve with 1/8"
NPT tap is an acceptable alternative to test gauge connec-
tion. Purchase the CSA design-certied equipment shutoff
valve from your dealer.
For propane/LP connections only, the installer must supply
an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas
pressure to between 11 and 13 inches of water. If you do
not reduce incoming gas pressure, burner system regula-
tor damage could occur. Install external regulator with the
vent pointing down as shown in Figure 14. Pointing the
vent down protects it from freezing rain or sleet.

CAUTION
Use only new black iron or steel pipe. Inter-
nally tinned copper or copper tubing can be
used per National Fuel Gas Code, Section
2.6.3, providing gas meets hydrogen sulde
limits, and where permitted by local codes.
Gas piping system must be sized to provide
minimum inlet pressure (listed on data plate)
at the maximum ow rate (BTU/hr). Undue
pressure loss will occur if the pipe is too
small.
CHECK GAS TYPE
Use proper gas type for the replace you are installing.
If you have conicting gas type, do not install replace.
See dealer where you purchased the replace for proper
replace according to your gas type.

LOCATION
WARNING
A qualied installer or service person must
connect appliance to gas supply. Follow
all local codes.
CAUTION
For propane/LP units, never connect
replace directly to the propane/LP supply.
This burner system requires an external
regulator (not supplied). Install the external
regulator between the burner system and
propane/LP supply.
When using copper or ex connectors use only ttings
approved for gas connections. The gas control inlet is
3/8" NPT.

NOTE : The gas line connection may be made using
1/2" rigid tubing or an approved ex connector. Since
some municipalities have additional local codes it
is always best to consult your local authorities and
the current edition of the National Fuel Gas Code
ANSI.Z223.1, NFPA54. In Canada CSA-B149 (1 or 2)
Installation Code.
A listed manual shutoff is factory installed upstream of
appliance. Union tee and plugged 1/8" NPT pressure tap-
ping point should be installed upstream of the appliance.
Figure 15
IMPORTANT: The main gas valve is for turning on or
shutting off the gas to the insert.
Check your building codes for any special requirements
for locating equipment shutoff valve to inserts.
Apply pipe joint sealant lightly to threads. This will prevent
excess sealant from going into pipe. Excess sealant in pipe
could result in clogged burner system valves.

Only persons licensed to work with gas
piping may make the necessary gas con-
nections to this appliance.
WARNING
A manual shut-off valve is factory installed
upstream of the appliance. Union tee and
plugged 1/8" NPT pressure tapping point
should be installed upstream of the appli-
ance. Figure 15
CAUTION
Use pipe joint sealant that is resistant to
liquid petroleum (LP) gas.
CAUTION
We recommend that you install a sediment trap/drip leg
in supply line as shown in Figure 15. Locate sediment
trap/drip leg where it is within reach for cleaning. Install
in piping system between fuel supply and burner system.
Locate sediment trap/drip leg where trapped matter is not
likely to freeze. A sediment trap traps moisture and contami-
nants. This keeps them from going into the burner system
gas controls. If sediment trap/drip leg is not installed or is
installed wrong, burner system may not run properly.

CHECK GAS PRESSURE
1. Check gas type. The gas supply must be the same as
stated on the appliance’s rating decal. If the gas supply
is different from the replace, STOP! Do not install the
appliance. Contact your dealer immediately.
2. Install and attach ex line provided on this appliance to
1/2" gas line.
3. After completing gas line connection, purge air from
gas line and test all gas joints from the gas meter to the
replace for leaks. Use a soap and water solution or a
gas sniffer.
4. To adjust ame height, turn HI/LO knob to HI to get
maximum pressure to burner. Turn HI/LO knob to LO to
get minimum pressure.
5. To check gas pressures at valve, turn captured screw
counter clockwise 2 or 3 turns and then place tubing to
pressure gauge over test point. Turn unit to high. Fig-
ure 16. After taking pressure reading, be sure and turn
captured screw clockwise rmly to reseal. Do not over
torque. Check test points for gas leaks with a soap and
water solution or an electronic gas leak detector.
