The ideal ame will be blue at the base and light orange above. The ames should be of medium height.
If the ames look like this (refer to Figure 59 or the Front Cover), no adjustment is needed. If the ames
are fairly short and mostly blue, the replace is getting too much air. Therefore, the air shutter should be
closed slightly until the correct ames are achieved. Flames that are very orange, with tall, dark, stringy
tips, are not getting enough air. Open the air shutter until the ames clean up. If the shutter is opened, or
closed all the way, and the correct ames 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.

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 ue
outlet to the ceiling, the ceiling thickness, the vertical rise through the attic or second story, and allow
for sufcient vent height above the roof line. For two story applications, a re stop is required at each
oor level. If an offset is needed in the attic, additional pipe and elbows will be required. To connect the
venting system to the appliance ue 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.

Figure 28 and 29 shows the range of possible vent congurations 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 ame 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 replace is cool or use welder’s
gloves or oven mitts.
2. Remove the glass door (see Maintenance and service - gLass door reMovaL) and the rebox bafe (see
Maintenance and service - fireBox BaffLe reMovaL).
3. Remove two (2) ¼” hex head screws for the restrictor, place restrictor in the ue collar (see Figure
30) and fasten in place with the two (2) ¼” hex head screws.
4. Re-install the rebox bafe and the door.
5. Wait for the unit to warm up to operating temperature to ensure a proper and clean burning unit.

the location of the appliance.
2. Direct vent pipe and ttings 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 oor, as much out of view as possible.
Place a bead of Mil-Pac on the outer edge of the inner exhaust
pipe (non-ared 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

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 ttings, are
designed to slide straight onto the male ends of adjacent pipes and ttings, 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 sufcient 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 at 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 re.
(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 ue 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.

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
the pipe is truly vertical. With roong nails, secure the support straps to the roof. Seal the nails holes

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 ashing 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 ow of ue gases and intake air.
(c) For multi story installations. A ceiling restop is required at the second oor, and any subsequent
oors (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 rst oor, 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 ll any required air spaces with insulation.
