include pregnant women, people with heart or

propane/LP gases are odorless. An odor-
making agent is added to the gas. The odor
helps you detect a gas leak. However, the
odor added to the gas 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 safe and proper operation of

Today’s homes are built more energy efcient
than ever. New materials, increased insulation,
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors to
keep the cold air out and the warm air in. Dur-
ing heating months, home owners want their
homes as airtight as possible.
While it is good to make your home energy
efcient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning ap-
pliances need fresh air for proper combustion
and ventilation.
Exhaust fans, replaces, clothes dryers, and
fuel burning appliances draw air from the house
to operate. You must provide adequate fresh
air for these appliances. This will insure proper
venting of vented fuel-burning appliances.

The following are excerpts from National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classications:
1. Unusually Tight Construction
2. Unconned Space
3. Conned Space
The information on pages 5 through 7 will help
you classify your space and provide adequate
ventilation.

The air that leaks around doors and windows
may provide enough fresh air for combustion
and ventilation. However, in buildings of un-
usually tight construction, you must provide
additional fresh air.

Example: Space size 20 ft. (length) x 16 ft.
(width) x 8 ft. (ceiling height) = 2,560 cu. ft.
(volume of space)
If additional ventilation to adjoining room
is supplied with grills or openings, add the
volume of these rooms to the total volume
of the space.
2. Multiply the space volume by 20 to determine
the maximum Btu/Hr the space can support.
________ (volume of space) x 20 = (Maxi-
mum Btu/Hr the space can support)
Example: 2,560 cu. ft. (volume of space) x
20 = 51,200 (maximum Btu/Hr the space can
support)
3. Add the Btu/Hr of all fuel burning appliances
in the space.
Vent-free replace _________ Btu/Hr
Gas water heater* _________ Btu/Hr
Gas furnace _________ Btu/Hr
Vented gas heater _________ Btu/Hr
Gas replace logs _________ Btu/Hr
Other gas appliances* +________ Btu/Hr
Total = ________ Btu/Hr
* Do not include direct-vent gas appliances.
Direct-vent draws combustion air from the
outdoors and vents to the outdoors.
Example:
Gas water heater _____________ Btu/Hr
Vent-free replace + ___________ Btu/Hr
Total =____________ Btu/Hr
4. Compare the maximum Btu/Hr the space
can support with the actual amount of
Btu/Hr used.
_______ Btu/Hr (maximum the space can
support)
_______ Btu/Hr (actual amount of Btu/Hr
used)
Example: 51,200 Btu/Hr (maximum the
space can support)
73,000 Btu/Hr (actual amount of
Btu/Hr used)
The space in the example is a conned space
because the actual Btu/Hr used is more than the
maximum Btu/Hr the space can support. You
must provide additional fresh air. Your options
are as follows:
A. Rework worksheet, adding the space of an
adjoining room. If the extra space provides an
unconned space, remove door to adjoining
room or add ventilation grills between rooms.
See Ventilation Air From Inside Building.
B. Vent room directly to the outdoors. See
Ventilation Air From Outdoors page 8.
C. Install a lower Btu/Hr replace, if lower Btu/Hr
size makes room unconned.

This fresh air would come from an adjoining
unconned space. When ventilating to an
adjoining unconned space, you must provide
two permanent openings: one within 12" of the
ceiling and one within 12" of the oor on the
wall connecting the two spaces (see options
1 and 2, Figure 3). You can also remove door
into adjoining room (see option 3, Figure 3).
Follow the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Air for Combustion and
Ventilation for required size of ventilation
grills or ducts.

Note: Your replace is designed to be used
in zero clearance installations. Wall or fram-
ing material can be placed directly against
any exterior surface on the rear, sides, or
top of your replace, except where standoff
spacers are integrally attached. If standoff
spacers are attached to your replace, these
spacers can be placed directly against wall
or framing materials.
Use the dimensions shown for rough openings
to create the easiest installation. See Built-In
Fireplace Installation, page 11.
IMPORTANT: Vent-free heaters add moisture
to the air. Although this is benecial, installing
replace in rooms without enough ventilation
air may cause mildew to form from too much
moisture. See Air for Combustion and Ventila-
tion, page 6.
IMPORTANT: Make sure the fireplace is
level. If replace is not level, log set will not
work properly.

Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 12" of the ceiling
and one within 12" of the oor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, Air for
Combustion and Ventilation for required size
of ventilation grills or ducts.
IMPORTANT: Do not provide openings for
inlet or outlet air into attic if attic has a thermo-
stat-controlled power vent. Heated air entering
the attic will activate the power vent.

2. When installing blower, install a properly
grounded, 120 volt three-prong electrical
outlet at replace location if an outlet is not
there. If possible, locate outlet so cabinet
mantel will cover it when installed (see
Figure 9).
3. Install gas piping to replace location. This
installation includes an approved exible
gas line (if allowed by local codes) after
the equipment shutoff valve. The exible
gas line must be the last item installed on
the gas piping. See Installing Gas Piping
to Fireplace Location, page 13.
4. Place hearth base accessory against wall at
installation location. Cut an access hole in
hearth top to run exible gas line to replace
(see Figure 9). Make sure to locate access
hole so cabinet mantel will cover it when
installed.
Note: You can secure base to oor using
wood screws. Countersink screw heads
and putty over.
5. Route exible gas line through access
hole in hearth base.
6. Center cabinet mantel on hearth base (see
Figure 10, page 11). Make sure mantel is
ush against wall.
7. Break off nailing anges (see Figure 11,
page 11) with hammer or pliers.
8. Place cardboard or other protective mate-
rial on top of hearth base. Carefully set
replace on protective material, with back
of replace inside mantel opening.
9. Attach exible gas line from replace gas
regulator to gas supply. See Connecting
Fireplace to Gas Supply, page 14.
