Recommended Installation Procedure
1. Frame the opening for the fireplace. Make sure to allow for vent installation.
2. If the facing is 1/2" or 7/8" thick (most common), secure the fireplace to the framing with
the nailing brackets (see "Nailing Brackets" for details).
NOTE: If the facing is not 1/2" or 7/8" thick, follow the directions below:
Place a strip of facing material to both sides of the fireplace opening (NOTE: the strips will
be removed after the fireplace is secured). The facing thickness must represent the total
thickness of the finished facing (e.g.: If tile is to be used, include the thickness of the
backboard, tile, and tile adhesive). Insert the fireplace into the framing. Slide it back until
the front edge of the nailing brackets are flush with the facing material. Secure the
fireplace using the plates located along the base of the fireplace.
3. Complete the gas line installation.
4. Complete the electrical hook-up.
5. Complete the vent installation.
6. Install the hearth (if applicable).
7. Install the facing.
8. Install the mantel (if applicable).

OTHER MASSACHUSETTS CODE REQUIREMENTS:
• Flexible connector must not be longer than 36 inches.
• Shutoff valve must be a “T” handle gas cock.
• Only direct vent sealed combustion products are approved for bedrooms or bathrooms.
• Fireplace dampers must be removed or welded in the open position prior to the installation of a fireplace insert or gas
log.
• The gas line must be installed in accordance with all local codes, if any; if not, follow ANSI
223.1 and the requirements listed below.
• The fireplace and gas control valve must be disconnected from the gas supply piping during
any pressure testing of that system at test pressures in excess of 1/2 psig. For pressures under 1/2
psig, isolate the gas supply piping by closing the manual shutoff valve.
• Leak test all gas line joints and the gas control valve prior to and after starting the fireplace.
Gas Line Location
• The gas inlet is located on the left side. It may be re-located to the base of the fireplace (see “Optional Gas
Line Location” on the following page).
The left side gas inlet is
located 2-7/8" above the
base of the fireplace.

Fuel
• This fireplace is designed either for natural gas or for propane (but not for both). Check the sticker on the top of
the gas control valve to make sure the correct fuel is used (see illustration on page 4).
Gas Line Connection
• Installation must be performed by a qualified installer, service agency or the gas supplier (In Massachusetts
a licensed plumber/gasfitter).
Gas Inlet Pressure Standard Input Pressure
Natural Gas 7" W.C. (1.74 kPA)
Propane 13" W.C. (2.73 kPA)
• If the pressure is not sufficient, make sure the piping used is large enough, the supply regulator is
adequately adjusted, and the total gas load for the residence does not exceed the amount supplied.
• The supply regulator (the regulator that attaches directly to the residence inlet or to the propane tank) should
supply gas at the suggested input pressure listed above. Contact the local gas supplier if the regulator is at
an improper pressure.

Vent Requirements
• The gas appliance and vent system must be vented directly to the outside of the building, and
never be attached to a chimney serving a separate solid fuel or gas-burning appliance. Each
direct vent gas appliance must use it's own separate vent system.
Vent Clearances
• The vent must maintain the required clearance to combustible materials to prevent a fire. Do
not fill air spaces with insulation.
Sides 1"
Above 3"
Below Horizontal or 45° Section 1"

ltitude Considerations
• This heater has been tested at altitudes ranging from sea level to 8, feet (2,4 M). In this testing we
have found that the heater, with its standard orifice, burns correctly with just an air shutter adjustment.
• Failure to adjust the air shutter properly may lead to improper combustion which can create a safety hazard.
Consult your dealer or installer if you suspect an improperly adjusted air shutter.
pproved Vent
• Use 8" diameter Model GS Direct Vent manufactured by Simpson Dura-Vent only. Follow the
installation instructions included with the vent. For the nearest Simpson Dura-Vent supplier,
call (8 ) 835-4429.
• Always use the high-wind termination (if applicable).

16 Installation (for qualified installers only)

Vent Installation
• Slide the vent sections together and turn 1/4 turn until the sections lock
in place.
• Screws are not required to secure the vent. However, three screws may
be used to secure vent sections together if desired.
• High temperature sealant is recommended at the appliance starter
section connection (use high-temperature silicone or Mill-Pac®).
• If disassembly is required, at time of re-assembly check to see if the vent
creates a tight fit. If it does not, apply high temperature sealant to the
joints of the affected sections.
• Horizontal sections require a 1/4" rise every 12" of travel
• Horizontal sections require non-combustible support every three feet (e.g.: plumbing tape)
• In addition to the requirements below, follow the requirements provided with the vent.
Vertical Termination
(use the "High Wind Terminatin"

Approved Vent Configurations
Restrictor Position
• A vent restrictor is built
into the appliance to
adjust the flow rate of
exhaust gases. This
ensures proper
combustion for all vent
configurations.
Depending upon the
vent configuration, you
may be required to
adjust the restrictor
position. The charts for
acceptable vent
configurations detail the
correct vent restrictor
position.
To Access the Restrictor:
Remove the face (with the stove
cool).

Determine the correct restrictor position (see the charts under "Approved
Vent Configurations" - the factory position is #1).
Lift up the adjustment plate and move it so the correct notch falls into the
slot on the adjustment bracket.
This restrictor is in position 1
(factory setting).
