Air Shutter:
The air shutter is controlled by
sliding the air shutter adjustment
screw (shown in Figure 5) either
forwards or backwards. The
adjustment screw, for the primary
air, is located on the bottom of the
firebox. The air shutter nut can be
accessed by removing the control
panel. This is best done during the
initial installation.
Sliding the shutter forwards
increases the primary air while
sliding the shutter backwards
decreases the primary air.
The air shutter allows the amount
of air coming into the fireplace to be
adjusted in order to accommodate
different climates and venting
arrangements. Start the pilot and
then the burner. Make sure the pilot
flame is burning normally and none
of the burner ports are plugged. Let
the fireplace burn for roughly fifteen
(15) minutes and then examine the
flames, compare the flames to
Figure 59 or the Front Cover.

Air Shutter Adjustment Nut

Figure 5: Air Shutter Adjustment.

Operating Instructions
For Your Safety, Read Safety Precautions
And Lighting Instructions Before Operating
The ideal flame will be blue at the base and light orange above. The flames should be of medium height.
If the flames look like this (refer to Figure 59 or the Front Cover), no adjustment is needed. If the flames
are fairly short and mostly blue, the fireplace is getting too much air. Therefore, the air shutter should be
closed slightly until the correct flames are achieved. Flames that are very orange, with tall, dark, stringy
tips, are not getting enough air. Open the air shutter until the flames clean up. If the shutter is opened, or
closed all the way, and the correct flames cannot be attained, turn off the gas and contact the dealer.
Warning: Incorrect air shutter adjustment may lead to improper combustion, which is a safety hazard.
Contact the dealer if there is any concern about the venturi adjustment.

This fireplace can use an optional remote control or an optional cordless wall thermostat. If either of
these are to be used to control the fireplace for the majority of the time, leave the ON/OFF switch (on the
rear of the unit) in the “ON” position. Consult the instructions included with the remote/wall thermostat
for operation guidelines. When insalling the Remote Control module, cut out the label along the dotted
line of the Cara Control Panel, and mount the module to the back of the panel using the two (2) provided
Torx T-20 screws and nuts.

Blower Speed:
For units equipped with blowers, the blower will come on only when the fireplace is up to temperature
(approximately 12 minutes with unit on high). The blower is equipped with a variable fan controller,
located in the front control panel. This manual control will adjust the fan speed from high to low or turn
the fan off. A remote control for the fan is available through your dealer.

• Check stove and flue system clearance requirements.
• Locate the stove where it can be accessed by a gas supply line.
• Locate the stove in a large and open room that is centrally located in the house. This will optimize heat
circulation and comfort.
• As the stove can be equipped with a convection fan, ensure that an electrical outlet is within 6 ft (1.8
m) of the stove.
• The flow of combustion and ventilation air must not be obstructed.

When planning your installation, it will be necessary to select the proper length of vent pipe for your
particular requirements. It is important to note when passing through a wall, the maximum allowable
wall thickness is 10 inches (25.4 cm); 1½ inches (3.8 cm) clearance to combustibles must be maintained.
Select the amount of vertical rise desired for “vertical-to-horizontal” type installations. To determine
the length of vent pipe required for vertical installations, measure the distance from the appliance flue
outlet to the ceiling, the ceiling thickness, the vertical rise through the attic or second story, and allow
for sufficient vent height above the roof line. For two story applications, a fire stop is required at each
floor level. If an offset is needed in the attic, additional pipe and elbows will be required. To connect the
venting system to the appliance flue outlet, a twist-lock adapter is built into the appliance at the factory.
Refer to Initial Installation - Vent Configuration and Restrictor Settings for venting parameters.
Your total vent pipe length must be within the grid area of Figures 28 and 29. If a 90° elbow is used in
the horizontal plane, 36” (91.4 cm) must be subtracted from the allowable horizontal run.
There are three (3) basic types of Direct Vent System installations. The three (3) types of installations are
shown in Figures 24 through 26.

Vent Configurations and Restrictor Settings:
Figure 28 and 29 shows the range of possible vent configurations if the unit is top vented, for vertical
and horizontal terminations, any layout that remains within the grid areas is acceptable. They also show
the vent restrictor required, relative to the length of vent pipe. Longer vertical vent lengths necessitate
greater restriction.
Having the fewest number of elbows is ideal, as they tend to disrupt air movement. Using 45˚ elbows is
preferable to using 90˚ elbows. Also, a shorter vent system will perform better than a longer one.
If the unit is rear vented it may have a maximum horizontal run of 36” (91.4 cm) and must be used with
a 36” (91.4 cm) snorkel termination.

Restrictor Installation:
The ENVIRO CARA has been designed for use with an add-in restrictor. The restrictor is designed to
maintain flame appearance when installing this unit with vertical chimneys as well as installations with
longer horizontal vent applications. It does this by controlling the amount of air moving through the vent
pipe.
1. Choose the appropriate restrictor for the installation (see Initial Installation - Vent Configurations and
Restrictor Settings). To avoid injury, install the restrictor when the fireplace is cool or use welder’s
gloves or oven mitts.
2. Remove the glass door (see Maintenance and Service - Glass Door Removal) and the firebox baffle (see
Maintenance and Service - Firebox Baffle Removal).
3. Remove two (2) ¼” hex head screws for the restrictor, place restrictor in the flue collar (see Figure
30) and fasten in place with the two (2) ¼” hex head screws.
4. Re-install the firebox baffle and the door.
5. Wait for the unit to warm up to operating temperature to ensure a proper and clean burning unit.

Figure 30: Flue Restrictor Installation.

Horizontal Installation:
1. Set the appliance in the desired location. Check to determine
if wall studs or roof rafters are in the way when the venting
system is attached. If this is the case, you may want to adjust
the location of the appliance.
2. Direct vent pipe and fittings are designed with special twist-lock
connections. Assemble the desired combination of black pipe
and elbows to the appliance adapter with pipe seams oriented
towards the wall or floor, as much out of view as possible.
Place a bead of Mil-Pac on the outer edge of the inner exhaust
pipe (non-flared end). Place a bead of high temperature
silicone on the male edge of the outer pipe. Push the pipe
sections completely together, then twist-lock one section
clockwise approximately ¼ turn, until the two sections are
fully locked. The female locking lugs will not be visible from

the outside, on black pipe. They may be located by examining the inside of the female ends as shown
in Figure 31.
Notes:
(a) Twist-lock procedure: four (4) indentations, located on the female end of the pipes and fittings, are
designed to slide straight onto the male ends of adjacent pipes and fittings, by orienting the four pipe
indentations so they match and slide into the four entry slots on the male end.
(b) Horizontal runs of vent pipe must be supported every 36” (915mm). Wall straps are available for this
purpose, also when running horizontal pipe minimum clearances to combustibles must be maintained;
2” (51mm) at top, 1½” (38mm) at sides, 1½” (38mm) at bottom.
3. With the pipe attached to the stove in the correct location,
mark the wall for a 10” (25.4cm) x 10” (25.4 cm) square hole
(refer to Figure 32). The center of the square hole should
match the center line of the horizontal pipe. Cut and frame the
10” (25.4cm) x 10” (25.4cm) hole in the exterior wall where
the vent will be terminated. Refer to Figure 23 and Table 7. If
the wall being penetrated is constructed of non-combustible
material i.e. masonry or concrete, a 7” (17.8cm) hole is
acceptable.
4. Position the horizontal vent termination in the center of the
10” (25.4cm) x 10” (25.4cm) hole, and attach to the exterior
wall with the four screws provided. Before attaching the vent
termination to the exterior wall, run a bead of non-hardening
mastic around the edges, so as to make a seal between the
termination and the wall. The arrow on the vent termination
should be pointing up, insure that the proper clearances to
combustible materials are maintained.

5. Before connecting the horizontal run of the vent pipe to the
vent termination, slide the black decorative wall thimble cover over the vent pipe.

6. Slide the appliance and vent assembly towards the wall, carefully inserting the vent pipe into the
cap assembly. It is important that the vent pipe extend into the vent cap a sufficient distance with a
minimum of 1¼” (3.2cm) overlap. Secure the connection between the vent cap pipe and the vent cap

7. Slide the decorative wall thimble up to the wall surface and attach with the screws provided. Apply
decorative brass or chrome trim if desired (see right image in Figure 33).
NOTES:
(a) The four (4) wood screws provided should be replaced with the appropriate fasteners for stucco,
brick, concrete, or other types of siding.
(b) For buildings with vinyl siding, a vinyl siding standoff, should be installed between the vent cap and
the exterior wall (see Figure 34). Attach the vinyl siding standoff to the horizontal termination. The vinyl
siding standoff prevents excessive heat from possibly melting the vinyl siding material. Note that the
horizontal vent termination bolts onto the flat portion of the vinyl siding standoff (shaded area in Figure
31), so that an air space will exist between the wall and the vent termination.
(c) The horizontal run of vent pipe must be level and should have a ¼ inch (6mm) rise for every
one foot (305mm) of run towards the termination. Never allow the vent to run downward. This
could cause high temperature and may present the possibility of a fire.
(d) The location of the horizontal vent termination on the exterior wall must not be easily blocked or
obstructed. Refer to Initial Installation - Vent Configurations and Restrictor Settings.
(e) When installing a vent pipe in a chase the minimum clearance to combustibles is 2” (51 mm).
(f) Maintain manufacturer’s clearances to combustibles with venting.

Vertical Installation:
1. Check the instructions for required clearances (air spaces) to combustibles when passing through
ceilings, walls, roofs, enclosures, attic rafters, or other nearby combustible surfaces. Do not pack air
spaces with insulation.
2. Set the gas appliance in the desired location. Drop a plumb bob down from the ceiling to the position
of the appliance flue exit, and mark the location where the vent will penetrate the ceiling. Drill a small
hole at this point. Next, drop a plumb bob from the roof to the hole previously drilled in the ceiling,
mark the spot where the vent will penetrate the roof. Determine if ceiling joists, roof rafters, or other
framing will obstruct the venting system. You may wish to relocate the appliance, or to offset, to avoid
cutting load bearing members.

box up through the roof line. Galvanized
pipe and elbows may be utilized in the
attic, as well as above the roof line. The galvanized finish is desirable above the roof line, due to the
higher corrosion resistance.
6. Once the pipe sections have been joined, and run up through the hole in the roof, slip an elbow strap
over the exposed sections, bend the support straps outwards, and push the elbow strap down to the
roof level, as shown in Figure 34. Tighten the clamp around the pipe section. Use a level to make sure

8. Continue to add pipe sections until the height of the vent cap meets the minimum code requirements.
Refer to Figure 38 and Table 6. Note that for steep roof pitches, the vent height must be increased. In
high wind conditions, nearby trees, adjoining roof lines, steep pitched roofs, and other similar factors
can result in poor draft, or down drafting. In these cases, increasing the vent height may solve the
problem.
9. Slip the storm collar over the pipe, and push it down to the top of the roof flashing as shown in Figure

NOTES:
(a) If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe
every 3 feet (91 cm), to avoid excessive stress on the elbows, and possible separation. Wall straps
are available for this purpose (see Figure 39).
(b) When ever possible, use 45° degree elbows instead of 90° degree elbows. The 45° degree elbow
offers less restriction to the flow of flue gases and intake air.
(c) For multi story installations. A ceiling firestop is required at the second floor, and any subsequent
floors (see Figure 40). The opening should be framed to 10” (25.4 cm) x 10” (25.4 cm) inside
dimensions, in the same manner as shown in Figure 36.
(d) Any occupied areas above the first floor, including closets and storage spaces, which the vertical vent
passes through, must be enclosed. The enclosure may be framed and sheet rocked with standard
building materials. However consult the appliance manufactures installation instructions for the
minimum allowable clearance between the outside of the vent pipe, and the combustible surfaces of
the enclosure. Do not fill any required air spaces with insulation.

CAUTION: NEVER OPERATE THIS APPLIANCE WITH THE GLASS DOOR REMOVED.

Important note: When the unit is
turned on for the first time, it should
be turned onto high without the fan
on for the first four (4) hours. This will
cure the paint, logs, gasket material
and the other products used in the
manufacturing process. It is advisable
to open a window or door, as the unit
will start to smoke and can irritate
some people. After the unit has gone
through the first burn turn the unit off
including the pilot, let the unit get cold
then remove the glass door and clean it
with a good gas fireplace glass cleaner,
available at your local ENVIRO dealer.

are broken due to handling or shipping, replace the rocks with new ones. Using the pictures provided,
carefully set the rocks in place.
NOTE: The rocks are fragile, particularly
after usage. Please handle with due care
during servicing.
1. Carefully remove rocks from box and check
there is no damage. It is very important to
install all rocks in their proper position to
ensure safe, optimum operating conditions.
2. Place the rock cluster onto the burner. There
are two (2) holes at the back corners of
the burner and two (2) aligning pins on the
bottom of the rock cluster (refer to Figures 60
& 61).

Secondary Installation

Figure 61: Rock Placement of Four Large Rocks.

Figure 62: Rock Placement of Two Medium Rocks.

3. The four (4) large rocks are placed across front
of burner (see Figures 61 & 62). These rocks
are all the same shape, but must be rotated
in different positions to fit in the cut-aways in
the burner base. When there installed correctly,
there should be no visible gaps between the
rocks and the burner base. The gaps between
the rock cluster and the four (4) large rocks
needs to be maintained as smaller gaps will lead
to carbon deposits and build up.
4. Place the two (2) medium rocks; one on either
side of the cluster as shown in Figures 62 & 63.
These rocks can not be placed down between
the others.

8. Light the unit to enure it has a good flame (see Front Cover).

CAUTION: NEVER OPERATE THIS APPLIANCE WITH THE GLASS DOOR REMOVED.

Figure 64: Rock Placement Complete.

NOTES:
a. Some sooting on the rocks is normal. The
sooting should just be a thin covering in some
places on the center three (3) rocks of the
rock cluster. There should not be continuous
build up.
b. Surface cracks may appear after prolonged
use. This is due to the expansion and
contraction of materials during heating
cycles. Surface cracks are not a problem as
long as the assemblies are maintaining there
positions, and operation does not appear to
be altered.
