INSTALLATION

A. Horizontal Termination

Refer to Chart A for horizontal venting recommendations. The
minimum vertical rise allowed for horizontal termination is 2' from
the top of the heater. The maximum horizontal run allowed for
venting is 15' with a minimum 4' rise.

CHART A

Note: A horizontal run of vent must have
a 1/4" rise for every 1 ft. of run towards
the termination. Never allow the vent to
run downward. This could cause high
temperatures and the possibility of a fire.

Fig. 3 - Horizontal Lenth

A single vertical to horizontal elbow is already calculated into the
allowable 15' run. Each additional elbow reduces the maximum
horizontal distance by three feet. Example: When using three
elbows, the maximum horizontal distance has been reduced to
9' (3 - 1 = 2 elbows x 3' = 6'; 15' max. - 6' of elbows = 9' of
horizontal run). Even with only these three elbows (the equivalent
of 6' additional horizontal feet) you now need a minimum of 4' of
vertical rise. See Chart A.

If a vertical-to-horizontal elbow is enclosed within a wall, floor or
ceiling, an air space clearance of 3" must be maintained.

Due to the many different combineations that can be used when
constructing venting, the number of vent sections required can
only be determined by the installer.

Horizontal venting must terminate within the shaded area shown in
Fig. 2. Chart A illustrates the figures included in that shaded area.
For example, if your vertical rise is the minimum two foot, venting
can terminate anywhere between 20 -1/2" (includes wall thickness
and assumes 4", and venting required to termination cap) and 10'.

Vent termination must not be recessed into the wall or siding.
Fig. 3 illustrates termination cap location and minimum dimensions
for each termination application. Or, follow ANSI Z223.1, latest
edition.

01-01 Page 9 29863C

Note: Horizontal runs will require the use of
one vent support for every 3' of vent.

1. Preparing the Wall for Horizontal Termination. A hole
measuring 10” wide and 10” high must be cut and framed in the
exterior wall where venting will be terminated.

The height of the hole must be located to meet all local and
national codes and not be easily blocked or obstructed. The

1

minimum height to the center of the horizontal vent is 59

/2''
from the base of the unit. This figure will increase by the length
of each vertically positioned vent section added to the venting
system. See Figure 4.

Figure 4 - Exterior Wall Hole

If the wall being penetrated is constructed of non-combustible
material (i.e.: masonry block or concrete) a 7 inch diameter
hole is acceptable. It is recommended that for masonry walls the
vent be wrapped with fiberglass insulation to prevent contact with
the masonry as the contact promotes premature deterioration of
the vent.

2. Assembling Venting Sections. Use only vent supplied or
listed for use with this Heater. To attach a straight section to
the top of the Heater, female end down, slide the pipe over the
outer Collar on the Heater while the inner flue will slip over the
Vent Inner.

MAINTAIN MINIMUM CLEARANCES OR GREATER AROUND
THE VENT SYSTEM. Do not pack air spaces with insulation or

other material.

Figure 5 - Twist-lock procedure

The Dura-Vent GS is unitized and twist-locks together. For the
twist-lock procedure, consult Figure 5 and do the following:

(1) Four indentations, located on the female ends of 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
ends. See Figure 5. Push the pipe sections completely together,
then twist-lock one section clockwise approximately one-quarter
turn, until the two sections are fully locked. The female locking
lugs will not be visible from the outside, on the Black Pipe or
fittings. They may be located by examining the inside of the
female ends.

(2) Horizontal runs of vent must be supported every three feet.
Wall Straps are available for this purpose.

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

When using the adjustable section, maintain a 1” overlap on
pipe sections and secure. It is also important that the vent pipe
extends a minimum of 1 1/2” into vent cap.

3. Termination Cap. Position the horizontal vent termination so
that 1 1/2” clearance is maintained on top of the vent sections
and 1 1/2” on sides.

Before attaching the Vent Termination to the exterior wall, run a
bead of non-hardening mastic around the outside edges to make
a seal between the Cap and the wall.

Attach Cap to exterior wall with four (4) wood screws, making
sure that arrow on Cap is pointing up. After Cap is attached,
make sure that a 1 1/2” is maintained from top of vent to combus­tibles.

Secure the connection between the vent pipe and the vent cap
by attaching the two sheet metal strips extending fromthe vent
cap assembly into the outer wall of the vent pipe. Use the two
sheet metal screws provided to connectthe strips to the pipe sec­tion. Bend any remaining portion of the sheet metal strip back
towards the vent cap, so it will be concealed by the decorative
wall thimble cover. See Fig.6.

Slide the Decorative Wall Thimble up the wall surface and attach
with the screws provided. Apply Decorative Brass or Chrome
Trim if desired. See Fig. 7.

4. Vertical Rise on the Exterior. For installations requiring
a vertical rise on the exterior of a building, 14” and 36” tall
Snorkel Terminations are available. Follow the same installation
procedures that are used for the standard horizontal termination
found in Step 3.

01-01 Page 11 29863C

NOTE: For buildings with vinyl siding, a Vinyl Siding
Standoff should be installed between the vent cap and
the exterior wall. Attach the Vinyl Siding Standoff
to the Horizontal Vent Termination. The Vinyl Siding
Standoff prevents excessive heat from possible melt­ing the vinyl siding material. NOTE: The HHW2 cap
incorporates it's own vinyl siding standoff. See Fig. 8.

B. Vertical Termination.

The following figures are the maximum distances from the top
of the unit, as well as the minimum air space clearances that
must be maintained: Maximum straight unsupported rise - 25';
Maximum height - 40' from the top of the unit. Maximum horizon­tal unsupported run - 3'; air space clearances around vertical
venting - 1" on all sides; air space clearances around horizontal
venting - 1
is being used in an enclosed wall, floor, or ceiling a top air space
clearance of 3" must be maintained. These clearances must be
maintained at all times.

1. Position the Heater.

Position the heater in its desired location. Maintain all clearances
to combustibles.

2. Preparing the Ceiling.

Drop a plumb bob down from the ceiling to the position of
the heater flue exit and mark the location where the vent will
penetrate the roof. Drill a small hole at this point. Next drop
a plumb bob from the roof to the hole previously drilled in the
ceiling and 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 or offset
the appliance to avoid cutting load bearing members.

To bypass any overhead obstructions the vent system may be
offset using a 45° elbow or a 90° elbow. Vent stabilizers have
straps for securing these parts to joists or rafters. lumbers tape
may be purchased locally and used in conjunction with vent
stabilizers. See Fig. 9

3. Assembling vent sections. Only use vent supplied and
listed for use with this Heater.

To attach a straight section to the top of the Heater, with
the female end down, slide that pipe over the outer Collar
on the Heater while the Vent Inner slips into the Flue of
the Heater. MAINTAIN MINIMUM 1" CLEARANCES OR

The Dura-Vent GS is unitized and twist-locks together. For the
twist-lock procedure, consult Figure 5 and do the following:

(1) Four indentations, located on the female ends of 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
ends. (Figure 5.) Push the pipe sections completely together,
then twist-lock one section clockwise approximately one-quarter
turn, until the two sections are fully locked. The female locking
lugs will not be visible from the outside, on the Black Pipe or
fittings. They may be located by examining the inside of the
female ends.

(2) Horizontal runs of vent must be supported every three feet.
Wall Straps are available for this purpose.

Assemble the desired lengths of black pipe and elbows. It is
necessary to reach from the Heater up through the round support
box. Ensure that all pipe and elbow connections are in their fully
twist lock position.

Using the mark from Step 2, drive a nail up through the roof to
mark the center. Measure to either side of the nail and mark
the opening required. This is measured on the horizontal; actual
length may be larger depending on the pitch of the roof. Cut out
and frame the opening. See chapter 25 of the Uniform Building
Code for Roof Framing details. A one inch minimum air space
clearance must be maintained between the vent system and the
roof.

Assemble lengths of pipe and elbows necessary to reach from
the ceiling support 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
its higher corrosion resistance.

4. Installing the Roof Flashing or Site-Produced Chase Top.
Position a Roof Flashing (or construct a Chase and Chase Top)
and secure in place with nails.

Continue to add Vent sections through the Roof Opening, main­taining at least 1” Air Space clearance. Major Building Codes
specify a minimum Vent (Chimney) height above the Roof top
depending on Roof Pitch. See Figure 10. Add Pipe sections
until the height of the Vent Cap meets the minimum Building Code
requirements described in Figure 10. Note that for steep roof
Pptches, the vent height must be increased.

These Vent System heights are necessary in the interest of
safety, however, they do not ensure draft-free operation. Trees,
buildings, adjoining Roof lines, adverse wind conditions, etc., may
create a ned for a taller Vent System should down drafting occur.

5. Termination Cap. Twist lock the Vent Cap.

C. Existing Masonry Chimney Installation
This installation is subject to local jurisdiction. Some codes

may require the use of another liner for intake air. If so, the
4” aluminum liner should be inside a 6” UL 181 listed liner.

This Heater can be vented through an existing Masonry Chimney
but the chimney must be lined with one UL 1777 listed 4” alumi­num flexible gas vent liner for exhaust. The existing Flue will
be used to supply the air intake to the galvanized steel Flue
system. See Figure 11. Before installing the liner system, the

chimney passageway should be cleaned and examined to
verify it is unobstructed and in good structural condition.

Measure and record the chimney dimensions to determine total
flexible liner requirements.

Follow the liner manufacturer’s instructions for installing the liner
in the chimney. Attach a flexible liner puller to the liner and secure
a rope to the puller. One person should feed the liner through
the chimney, and another person should pull the liner from the
bottom, with the rope, guiding the liner down the chimney. After
feeding the liner down the chimney, form a 90˚ angle and bring
the liner through the hole in the chimney wall. (If running two
liners, run the 6” liner first and then the 4” inside of it.) Extend the
liner through the wall of the chimney and attach it to the venting
system extending from the top of the Heater.

Construct a metal flashing large enough and strong enough
to cover the chimney opening and support the Heater Vertical
Termination Cap. The flashing needs to fold down over and
around the outside of the masonry chimney so that it can be
secured to the chimney by 4 screws. See Figure 12. The
flashing will require a hole at least 6 1/2'' in diameter. (If using a
6” liner, extend the 6'' flexible liner through the flashing and attach
it to the VTA (Vertical Termination Adapter) with screws provided.)
Secure the VTA to the flashing with the screws provided and seal
the VTA/Flashing joint with a silicone sealant to prevent moisture
from running down the liner into the chimney.

Attach the 4'' gas vent liner to the Vertical Termination Cap with
screws provided, then attach the Termination Cap to the VTA with
screws provided. See Figure 12.

D. Existing Class A Metal Chimney Termination

In many cases where a DOVRE DV450S is replacing a wood­stove, much of the existing Class A Metal Chimney can be
incorporated into the direct vent system.

The existing chimney must comply with NFPA-211 codes and any
local code requirements.

The chimney should be cleaned and examined to verify
it is unobstructed and in good structural condition. Any
structural weaknesses such as cracks, leaky joints, cor­roded or warped surfaces can have an adverse effect on
the performance of this Heater and should be replaced or
repaired.

Whenever an existing Class A Metal Chimney is on an outside
wall, removal of the chimney and the use of the minimum hori­zontal direct vent termination kit may be less expensive.

When using an existing Class A Metal Chimney the following
requirements are necessary:

Minimum size diameter is 6 inches.
Minimum height from the base of the stove to the top of termina-

tion cap is 9 feet.
The vent from the top of the Heater to the Chimney must be rigid

vent sections. A 4'' UL 1777 listed gas vent aluminum flexible
liner can be used inside the chimney. The flexible liner must
be secured to the last rigid section with three (3) sheet metal
screws. A minimum 3 inch overlap is required. Remove and
discard the existing chimney termination cap.

Determine the length of the 4'' UL 1777 listed gas vent flex liner
required to meet the vent sections at the top of the Heater.

Follow the liner manufacturer’s instructions for installing the liner
in the chimney. Attach a flexible liner puller to the liner and
secure a rope to the puller. One person should feed the liner
through the chimney, and another person should pull the liner
from the bottom, with the rope, guiding the liner down the chim­ney. Extend and run the 4'' gas vent liner down the chimney
leaving 10'' extending from the top of the chimney stack.

Install and secure the VTA (Vertical Termination Adapter) onto the
chimney with the brackets provided.

Place and secure the Termination Cap on the VTA with the
screws provided. See Figure 13.

D. Creating the Coal Bed Look.

Ember Chunks.

Randomly place the Ember Chunks on the Burner Pan between
and in line with the two front logs, creating a small wall of
embers. Do not allow the Chunks to cover the burner ports or air
holes in the Burner Pan as this may restrict air and/or gas flow,
creating a less than satisfactory performance. Too much restric­tion can cause improper combustion and sooting (especially with
an appliance using propane gas). It is not necessary to use all of
the Chunks supplied with the unit.

Once the Burner Pan has been correctly covered with Ember
Chunks, place a single row of ember Chunks on the ember tray
located at the front of the Log Assembly.

Once the Ember Chunks are in place, a thin layer of Mineral Wool
may be bridged over the Chunks for greater enhancement.

Lava Rock.

Distribute the lava rock over the surface of the hearth pan next
to the glass being careful not get lava rock down into the air
inlet slots or onto the surface of the Burner Pan. The lava rock
does not change the flame and does not have to be used. A
different look to to the front of the unit is to add a row of ember
Chunks.

DV450S DIRECT VENT ROOM HEATER

E. Adjustable Flue Restrictor

The DV450 has an adjustable flue restrictor for maximum per­formance for vertical installations. The unit is shipped with the
restrictor in the open position and should be left open with any
horizontal installations.

The adjustment screw can be accessed by reaching through
the center air outlet slot at the top of the front face. See Figure

25. The slot of the screw head indicates the position of the
restrictor. See Figure 25. Turn the screw with a straight blade
screwdriver to close the restrictor as necessary.

The amount to close the restrictor will depend on the vent
height. If the vertical height is 20 feet or more, the restrictor
can be closed all the way. Anything less will require some
setting less than closed. The setting will vary depending on
the installation.

Any offsets in a vertical installation will restrict the system and
the flue restrictor will not need to be closed as much.

LIGHTING INSTRUCTIONS

FOR YOUR SAFETY READ BEFORE LIGHTING

WARNING!

If you do not follow these instructions exactly, a fire or explosion may result

causing property damage, personal injury or loss of life.

A. This gas appliance has a manual ignition device that lights the pilot.
When lighting the pilot, follow these instructions exactly.

B. STOP! BEFORE READING FURTHER, smell around the appliance
area for gas. Be sure to smell next to the floor because some gas is
heavier than air and will settle to the floor.

WHAT TO DO IF YOU SMELL GAS:

*Do not try to light the appliance.
*Do not touch any electric switch; do not use any telephone
in your building.
*Immediately call your gas supplier from a neighbor’s
telephone. Follow the instructions of your utility.
*If you cannot reach your utility, call the fire department.

LIGHTING INSTRUCTIONS

1. STOP! Read the safety information above.

2. Turn off all electric power to the appliance. If your appliance has a
thermostat, set to lowest setting.

3. Open control access panel.

4. Find the pilot. The pilot is inside the combustion chamber next to the
main burner.

C. IF THE PILOT LIGHT AND BURNER WENT OUT DURING USE,
YOU MUST TAKE THE GLASS OFF THE APPLIANCE AND WAIT TO
CLEAR OUT ANY GAS. FOLLOW THE LIGHTING INSTRUCTIONS
BELOW.

D. Use only your hand to push in or turn the gas control knob to light
the pilot. Never use tools. If the knob will not push in or turn by hand,
do not try to repair it; call a qualified service technician. Using a tool
or attempting repairs may result in a fire or explosion.

E. Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the appli­ance and to replace any part of the control system and any gas
control that has been under water.

7. Smell for gas, including near the floor. If you don’t smell gas, go to
the next step. If you smell gas, wait another five (5) minutes or until
the gas odor is no longer present before continuing. If the odor of gas
does not disappear after fifteen (15) minutes, STOP! Follow “B” in the
safety information above.

8. Replace glass panel if it has been removed.

9. Turn gas control knob counterclockwise to the “PILOT”
position.

10. Push the gas control knob in all the way and hold. At the same time,
push in red ignition button repeatedly until the pilot lights. Never hold the
gas control knob in for more than ten (10) seconds if the pilot does not
light. Once the pilot lights, continue to hold the gas control knob in for 15
seconds. Release the gas control knob and it will pop back up. If pilot
does not remain lit, repeat steps 6 through 9.

5. If the gas control knob is at the “OFF” position, go to step 7. If the gas
control knob is at the “ON” position, go to step 6.

6. If the pilot light went out during normal use with the gas control knob at
the “ON” position, turn the gas control knob to the “OFF” position. REMOVE
THE FIXED GLASS PANEL. Wait ten (10) minutes to clear out any gas.

01-01 Page 22 29863C

*If gas control knob does not pop back up when released, turn the knob
to “OFF” and call your service technician or gas supplier.

*If the pilot will not stay on after two attempts, turn the gas control knob to
“OFF” and call your service technician or gas supplier.

11. Turn gas control knob counterclockwise to the
“ON” position. The knob can be turned to the “ON” position only if it
is popped out.

12. Close the access panel.

13. Turn on electrical power to the appliance. If equipped with a
thermostat, set to the desired setting.

3. Open control access panel.

4. Turn gas control clockwise to “OFF”.

5. Close control access panel.

DV450S DIRECT VENT ROOM HEATER

Upon completing the gas line connection, a small amount of air
will be in the lines. When first lighting the pilot light, it will take a
few minutes for the lines to purge themselves of this air. Once the
purging is complete, the pilot and burner will light and operate.

Subsequent lightings of the appliance will not require such
purging. When lit for the first time, the appliance will emit a slight
odor for an hour or two. This is due to paint and lubricants used in
the manufacturing process. Additionally, for the first few minutes
after each lighting, vapor may condense and fog the glass and
the flames may be blue. After a few minutes, this moisture will
disappear and within 15-30 minutes the flames should become
yellow.

CAUTION: During the initial purging and sub-

sequent lightings, NEVER allow the gas valve
control knob to remain depressed in the “pilot”
position without pushing the red ignitor button at
least once every second.

ON/OFF SWITCH FOR THE BURNER

The on/off switch for the burner is located at the rear of the unit.

The knob beside the switch controls the flame setting. Turning
clockwise increases the flame and counter-clockwise turns the
flame to low. See Figure 27.

Figure 27 Flame Adjustment

Figure 28

Air Shutter Adjustment

Note:

Allow the unit to cool before replacing the front face.

Allow the unit to operate about 15-20 minutes. This will give
the flame time to reach its height and color before making
adjustments to the air shutter. As the shutter is closed, the flame
should get taller and darker.

The appliance may produce a noise, caused from metal
expansion and contraction as it heats up and cools down. This
noise is similar to one that a furnace or heat duct may produce
and does not affect the operation or longevity of the the unit.

Keep the control compartment, logs, and burner area surrounding
the logs clean by vacuuming or brushing at least twice a year.

CAUTION: The Logs can get very hot -

handle only when cool.

SEASONAL SHUTDOWN

Turning the valve to off at the end of the season will prevent gas
from running to the appoiance while not in use in the off season.
However, leaving the pilot on does not consume a large amount
of gas and the pilot will help keep the moisture and insects out
of the system.

AIR SHUTTER ADJUSTMENT

The air shutter adjusts the amount of air that mixes with the gas
as it enters the Burner Pan. It is used to fine tune the flame as
necessary for differences in altitude and vent configuration. The
shutter is shipped in the open position.
It can be adjusted by removing the front face and turning the
adjustment screw. See Figure 28.
Turning the screw in will close the shutter; turning the screw out
will open the shutter.
The shutter can be adjusted while the unit is in operation.
However, the unit should be shut off and allowed to cool before
removing the front face.

01-01 Page 23 29863C

OPERATION PROCEDURE DURING REGULAR USE

Simply turn the switch/thermostat to the ON position. THis will
ignite the main burner.

SHUTDOWN DURING REGULAR USE

Simply turn the switch/thermostat to OFF. This will disengage the
burner and the falmes will extinguish.

Cleaning the burner and control compartment

Keep the burner compartment clean. Brush this area with a
clean, dry paint brush and vacuum at least once a year. Always
turn off the gas valve and ON/OFF switch before cleaning.

Checking flame patterns

Visually check the flame of the burner periodically, making sure
the flames are steady; not lifting or floating. The flame color
should be blue with yellow tips. The thermopile tip should be
covered with flame. See Figure 20.

NOTE: If the air shutter is open all the way and the
flames remain sooty, shut off gas to the appliance and
contact a qualified gas service technician.

If the vent configuration is installed incorrectly, the vent
may cause the flames inside the appliance to lift or
“ghost” - a dangerous situation. Inspect the flames after
installation to ensure proper performance. If the vent
configuration is correct, yet the flames are lifting or ghost­ing, shut off gas to the appliance and contact the dealer
for information on remedying the problem.

Venting system inspection

The heater and venting system should be inspected before use
each season, and at least annually, by a qualified field service
person, to ensure that the flow of combustion and ventilation
air is not obstructed.

Cleaning the glass

It is recommended to wear gloves while handling or removing
the glass. DO NOT REMOVE THE GLASS WHEN HOT.

WARNING!

Do not use this heater if any part has been under
water. Immediately call a qualified service techni­cian to inspect the heater and to replace any part of
the control system and any gas control which has
been under water.

Figure 20 - Standing Pilot

Note: Operation of a Direct Vent Heater may
be sporadic in high wind situations.

Note: When cleaning the glass, NEVER use abrasive
materials. NEVER clean glass when hot.

To clean the glass, use a non-abrasive, mild cleaning solution.
(For example, a glass cleaner for stubborn film, or an oven
cleaner.) Apply an adequate amount to the glass and wipe
off with a damp cloth. Be sure all cleaner is thoroughly rinsed
from the glass.

Never operate this heater without the glass properly secured in
place or if the glass is broken.

In the event of glass breakage, follow door removal instruc­tions. This will allow the removal of all glass fragments and
sheet metal edge protection strips. Vacuum all remaining glass
pieces with a shop vac. (DO NOT VACUUM IF PIECES ARE
HOT.) Replace glass ordered direct or through your local
distributor. Never use substitute material. Only ceramic glass
may be used on this heater.

Log cleaning

Carbon build-up can be removed with a vacuum cleaner.
