blue, the replace is getting too much
air. Therefore, the air shutter should be
closed (push in) slightly until the correct
ames are achieved. Flames that are
very orange, with tall, dark, stringy tips,
are not getting enough air. Open (pull
out) the venturi until the ames clean
up. If the venturi is opened, or closed all
the way, and the correct ames cannot
be attained, turn off the gas and contact
the dealer.
Warning: Incorrect venturi adjustment
may lead to improper combustion, which
is a safety hazard. Contact the dealer if
there is any concern about the venturi
adjustment.

Operating Instructions
For Your Safety, Read Safety Precautions And
Lighting Instructions Before Operating
E) Turn on all electrical power to the unit.
NOTE: Check that all burner holes are lit.
TO TURN GAS FIREPLACE OFF:
Flip switch to OFF to turn off burners only.
If the replace is to be turned off for the season,
or for servicing, turn the gas shut off valve to
OFF. DO NOT FORCE IT. If the unit is going to
be serviced, turn off the electrical power to the
unit as well.
NOTE: When the unit is turned on for the rst time, it should be turned onto high, with the fan OFF,
for the rst two to four hours. This will cure the paint, logs, gasket material, and other products used
in the manufacturing process. It is advised that a door or window be opened as the unit will start to
smoke, which can irritate some people. After the unit has gone through the rst burn, turn the unit OFF,
including the pilot, and let the unit get completely cold. Then remove the glass and clean it with a good
gas replace glass cleaner, available at your local Enviro dealer. See “MAINTENANCE AND SERVICE; GLASS
DOOR REMOVAL” and “MAINTENANCE AND SERVICE; CLEANING THE GLASS.”
REMOTE CONTROLS:
This replace can use an optional remote control or an optional cordless wall thermostat. If either of
these are to be used to control the replace for the majority of the time, leave the ON/OFF switch (on the
control panel) in the remote/thermostat position. Consult the instructions included with the remote/wall
thermostat for operation guidelines.

BURNER LIGHTING:
A) Make sure the pilot is lit.
B) Turn gas control knob COUNTER CLOCKWISE to ON.
C) Flip the burner switch to ON.
D) Turn HI/LO knob to the desired ame height.
The blower will come on only when the replace is up to temperature
(approximately 20 minutes). The speed of the fan can be changed by turning the
fan control knob. To turn the blower off, turn the knob COUNTER CLOCKWISE
until it “clicks” off (Figure 6).
It is advisable not to operate the blower below 1/3 speed as it puts a strain on the
windings of the blower and running the blower at lower speeds could also cause
premature fan failure.

Maintenance And Service
ROUTINE MAINTENANCE:
At least once a year, run through the following procedures to ensure the system is clean and working
properly. Check the burner to see if all the ports are clear and clean. Check the pilot to make sure it is not
blocked by anything. The pilot ame should be blue with little or no yellow on the tips.
Warning: Clearances must be sufcient to allow access for maintenance and service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts
specically approved with this appliance may result in property damage or personal injury.
The venting system must be periodically examined; it is recommended the examination is done by a
qualied agency.
CLEANING THE GLASS:
When the replace has cooled, remove the face of the replace along with the glass. See MAINTENANCE
AND SERVICE - GLASS DOOR REMOVAL. Check the gasket material on the back of the glass, making sure that
it is attached and intact.
During a cold start up, condensation will sometimes form on the glass. This is a normal condition with all
replaces. However, this condensation can allow dust and lint to cling to the glass surface. Initial paint
curing of the appliance can leave a slight lm behind the glass, a temporary problem. The glass will need
cleaning about two weeks after installation. Use a mild glass cleaner and a soft cloth; abrasive
cleaners will damage the glass and plated surfaces. Depending on the amount of use, the glass
should require cleaning no more than two or three times a season. Do not clean the glass when it is
hot.
CLEANING THE FIREBOX:
Remove the logs carefully, as they are very fragile. Gently remove all the embers and rock wool and place
on a paper towel. Vacuum the bottom of the rebox thoroughly. Carefully clean any dust off the logs and
remove any lint from the burner and pilot. At this time, inspect the burner pan for cracking or severe
warping. If a problem is suspected, contact the dealer. Check the logs for deterioration or large amounts
of soot; a small amount on the bottom side of the logs is normal. Replace the logs and embers as in the
LOG SET AND EMBER INSTALLATION section. If new/more embers and rock wool are required, contact your
nearest ENVIRO dealer.
REPLACING THE GLASS:
The glass in the replace is a high temperature ceramic. If the glass is damaged in any way, a factory
replacement is required (see PARTS LIST - COMPONENTS). Wear gloves when handling damaged glass door
assembly to prevent personal injury. When the glass door assembly is being transported, it must be
wrapped in newsprint and tape and/or a strong plastic bag. Do not operate with the glass front removed,
cracked or broken. Removal and replacement of the glass from the door must be done by a licensed or
qualied service person. The glass must be purchased from an ENVIRO dealer. No substitute
materials are allowed.

Maintenance And Service
CLEANING DECORATIVE SURFACES:
Painted and porcelain faces should be wiped with a damp cloth periodically. If a plated face has been
purchased, it should be unpacked/unwrapped carefully to avoid getting anything on the surface of the
nish, including cleaners, polish and nger prints. It is important to note that ngerprints and other
marks can leave a permanent stain on plated nishes. To avoid this, give the face a quick wipe with
denatured alcohol on a soft cloth BEFORE lighting the replace. Never clean the face when it is
hot. Do not use other cleaners as they may leave a residue, which can become permanently etched into
the surface.
If your ngers come into contact with the antique copper nish, the oils left as ngerprints on the copper
can cause discoloration, which will eventually turn green in that area. You can clean the patina or discolored
areas of the antique copper nish with “OO” 3M green sanding pads. These can be purchased from most
hardware stores. On the areas with discoloration, use the sanding pads to sand in the same direction as
the brushed nish, then blend the nish by feathering in the surrounding area. This renishing procedure
has been approved by the manufacturer and will not harm the nish. Please note: ANTIQUE COPPER IS
THE ONLY FINISH THAT CAN BE SANDED, DO NOT SAND PEWTER, GOLD OR NICKEL FINISHES.
GLASS DOOR REMOVAL:
In order to install the log set, and
for regular cleaning, the glass door
must be removed. There are two
(2) door latch mechanisms under
the glass door shown in Figure
7. Each latch has two (2) nger
grooves, use these to pull the
mechanisms straight out. When
the bottom latches are unhooked,
lift the door straight up over the
placement pins at the top of the
door, shown in Figure 8.
To replace the glass door, simply
reverse the above procedure.
Warning: Do not touch or attempt
to remove the glass if the replace
is not completely cold.
WARNING: Never operate
the replace with the glass
removed.

INTRODUCTION:
This section of the owner’s manual is for the use of qualied technicians only. Fireplace placement,
hearths, facing, mantles, and venting terminations will be covered, as well as the gas and electric
systems. There are several installation safety guidelines that must be adhered to. Please carefully read
the safety precautions at the front of this manual.
Warning: Clearances must be sufcient to allow access for maintenance and service.

The location for the replace can be along a
wall, raised or at oor level, or in a corner.
There are specic framing measurements for
each situation. The basic opening should have
the dimensions shown in Figure 6.
The replace must have a strong and level
surface to be placed on. The surface should be
made of wood or a non-combustible material,
not carpet.
The framing boards may touch the top and
back standoffs, but no insulating material
can be placed between the frame and the
standoffs.
The gas line,  inch NPT, should be brought
to the right side of the replace. If this set up
is inconvenient, the electrical wire and the gas

line conguration can be reversed.
The location should be chosen so the replace will be at least 36 inches (91.4 cm) from drapes, doors
and other combustibles. The framed opening should also be a minimum of 1 inches (2.5 cm) from the
nearest perpendicular wall (sidewall to the edge of the opening).
The DV36 is designed so it can be installed at oor level without a required hearth.

Mount the two framing mount brackets on each side and secure the replace
to framing with screws or nails (refer to Figure 7). The brackets will allow
for a ” (13 mm), ” (16 mm), ” (19 mm) thick nishing wall. The wall
may be nished up to the replace facing with combustible material.

VENT PARTS AND TERMINAL CLEARANCES:
The Sherwood Home Collection of replaces have been tested and certied for use with SIMPSON
DURAVENT TYPE GS PIPE FOR GAS STOVES. SECURITY CHIMNEY’S “SECURE VENT DIRECT VENT
SYSTEM” and SELKIRK “METALBESTOS MDV VENT SYSTEM” kits are available for horizontal venting.
When using Simpson Duravent, it is recommended that, before installation, a bead of RTV High
Temperature Silicone should be applied to each outer vent joint, and Mil-Pac to each inner joint. When
planning an installation, it will be necessary to select the proper length of vent pipe for the particular
requirements.

A 1 inch (2.5 cm) clearance to combustibles must be maintained around any vertical vent pipe. Around
a horizontal vent pipe, the clearance to combustibles should be 2 inches (5 cm) above and 1 inches (4
cm) on the sides and bottom. When combustible materials are directly above a 90° elbow, 3 inches (7.6
cm) of clearance are necessary. A 10 inches (25 cm) x 10 inches (25 cm) frame will assure the proper
support and spacing for the vent pipe as it passes through the wall. Installations in Canada require that a
wall thimble be used for passing through walls and ceilings, see Figure 21. All sealing and vapour barriers
must comply with local building codes.

When planning an installation, it is necessary to select the
proper length of vent pipe for the particular requirements. The
conguration of the venting pipes depends on the locations
of walls, ceilings and studs. However, the pipes cannot be
of arbitrary length and arrangement. Because the length of
the vertical and horizontal sections dramatically affects the
burning efciency of the replace, certain guidelines have
been set in the Vent Congurations section.

VENT CONFIGURATIONS AND RESTRICTOR SETTINGS:
Figures 23 shows the range of venting options, it shows possible vent congurations if the unit is top
vented, for vertical and horizontal terminations, any layout that remains within the shaded area is
acceptable. 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.
The vent restrictor controls the amount of air moving through the vent pipe. Longer vertical vent lengths
necessitate greater restriction; position 1 is open and position 5 is maximum restriction. Figure 23
NOTE: The total length of the vent pipes can
not exceed 32 feet (15.12 m). Any combination
of rise and run can be used as long as it lays
within the shaded area (a total of three (3) 90°
elbows or six (6) 45° elbows can be used).
In addition to what is shown, if a 90°
elbow is used in the horizontal plane,
3 feet (91.4 cm) must be subtracted
from the allowable horizontal run
(for each 45° elbow, 1 feet
must be subtracted from the
allowable horizontal run).
shows the vent restrictor position required,
relative to the length of vent pipe. The vent
restrictor is located in the center of the
replace, above the glass. Figure 24 shows
the vent restrictor dial and the holes that
indicate the different levels. To avoid injury,
it is best to make this adjustment when the
replace is cool or use welder’s gloves or
oven mitts.
Note: 0,0 in Figure 23 represents a 90˚
bend directly off the outlet of the unit, 41
inches (106 cm) from oor, in all horizontal
instances except when using Selkirk and
having less than a 4 feet (1.22 m) rise and
8 feet (2.44 m) horizontal offset. In this
case, a 1 foot (30.5 cm) rise must be added
below the 90˚ bend.
Note for rear vented: At 29 inches (75
cm) up, the maximum horizontal rear exit
vent length is 17 inches (43 cm) with a 45°
elbow (see Figure 12).

HORIZONTAL TERMINATION:
NOTES:
1. Horizontal pipes must not be level. For every 12 inches (305 mm) of horizontal travel
(away from the stove), there should be at least  inch (6.4 mm) of vertical travel. Never
allow the vent to run downward, as this could cause high temperatures or even present
the possibility of a re.
2. The exterior of the horizontal
vent termination must not be
blocked or obstructed.
3. If the vent termination is not
being attached to wood, the
four wood screws provided
should be replaced with
material appropriate fasteners.
4. For buildings with vinyl siding,
a vinyl standoff should be
installed between the vent cap
and the exterior wall. Attach
the vinyl siding standoff to
the horizontal termination.
Note that the termination
bolts onto the at portion of
the standoff, providing an air
space between the wall and
the vent termination. The air
gap prevents excessive heat
from possibly melting the vinyl
siding.
5. Horizontal pipes must be
supported every 3 feet (914
mm). Plumber’s all round strap will sufce.
6. When running horizontal pipe, clearances to combustibles must be maintained 1 inches (38 mm)
sides, 1 inches (38 mm) bottom, and 2 inches (51 mm) top.
Step 1. Set the replace in the desired location. Check to determine if wall studs will be in the way when
the venting system is attached. If this is the case, the location of the replace may have to be
adjusted or the venting may have to be offset.
Step 2. Direct vent pipe sections are designed with special twist-lock connections. Dry t the desired
combination of pipe and elbows to the appliance adaptor.
Step 3. With the pipe in the correct position and attached to the replace, mark the wall for a 10 inches
(25.4 cm) x 10 inches (25.4 cm) square hole (see Figure 21). The center of the hole should
match the center line of the horizontal pipe. Cut and frame the hole in the exterior wall where
the vent will be terminated. If the wall being penetrated is made of a non-combustible material
(i.e. masonry or concrete) a 7 inches (17.8 cm) hole is acceptable.

Step 3. To install the Round
Support Box/Wall Thimble
in a at ceiling, cut a 10
inch (25.4 cm) square hole
in the ceiling, centered in
the hole drilled in Step 2.
Frame the hole as shown
in Figure 21.
Step 4. Assemble the desired
lengths of black pipe
and elbows necessary to
reach from the appliance
adapter up through the
Round Support Box.
Insure that all pipe and
elbow connections are
in their fully twist-locked
position. Figure 26. Vertical Vent Termination
NOTE: For Simpson Duravent only, place a bead of Mil-Pac or Rutland No 78 Stove and Gasket Cement
on the outer edge of the inner exhaust pipe (non-ared end). Push the pipe sections together, then twist
about  turn, making sure the two sections are fully locked. Wrap all seams with foil ducting tape.
Step 4. With the hole now framed, the wall thimble installed, and the pipe extending into the wall,
proceed to the outside. Attach the termination to the pipe using RTV and Mil-Pac or Rutland No
78 Stove and Gasket Cement to seal joints. The vent pipe must extend into the vent cap at least
1 inches (3.2 cm). Secure the connection between the vent cap and the pipe by attaching the
two (2) sheet metal straps, which extend from the vent cap assembly to the outer wall of the
vent pipe. Bend any remaining portion of the strap back towards the vent cap. Security Secure
Vent uses a twist lock cap.
Step 5. Position the horizontal vent termination in the center of the 10 inches (25.4 cm) square hole
and attach to the exterior wall with the four screws provided. The arrow on the vent termination
should be pointing up. Run a bead of non-hardening mastic around the edges of the vent
cap, to make a seal with the wall. Ensure the proper clearances to combustibles have been
maintained.
VERTICAL TERMINATION:
Step 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.
Step 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.
