Operation of improperly installed and maintained venting system could result in
serious injury, property damage or loss of life.
INSTALLATION PRECAUTIONS
INSTALLATION PLANNING
Consult local building codes before beginning the
installation. The installer must make sure to select the
proper vent system for installation. Before installing vent
kit, the installer must read this stove manual and vent
kit instructions.
There are two basic types of direct-vent installation:
Only a qualified installer/service person should install venting system. The installer must follow these safety rules:
• Wear gloves and safety glasses for protection.
• Use extreme caution when using ladders or when
•
on rooftops.
Be aware of electrical wiring locations in walls and
ceilings.
The following actions will void the warranty on your venting system:
• Installation of any damaged venting component.
• Unauthorized modification of the venting system.
• Installation of any component part not manufactured
WARNING
Failure to follow these instructions will
void the warranty.
This stove must be vented to the outside.
The venting system must NEVER be
attached to a chimney serving a separate
solid fuel burning appliance. Each gas
appliance must use a separate vent system.
Do not use common vent systems.
WARNING
NOTICE
•
or approved by MHSC.
Installation other than permitted by these instructions.
Horizontal sections of this vent system
require a minimum clearance of 2" from
the top of the pipe and 1" minimum to the
sides and bottom. Vertical sections of this
system require a minimum of 1" clearance to
combustible materials on all sides of the pipe.
Only a 1" clearance is required where the vent
passes through the nearest vertical wall.
203000245
It is important to select the proper length of vent pipe for
the type of termination you choose. It is also important to
note the wall thickness.
FOR HORIZONTAL TERMINATION
Select the amount of vertical rise desired. The horizontal
run of venting must have 1/4" rise for every 12" of run
towards the termination.
You may use up to three 90° elbows in this vent configuration. Refer to Horizontal Termination Configurations on
Page 13.
WARNING
Use only approved 4" x 6B\," MHSC or Simpson DuraVent
venting components with this appliance. Refer to Page 37
for approved venting component part numbers.
• Horizontal Termination
• Vertical Termination
Never run the vent pipe level or downward.
This may cause excessive temperatures
which could cause a fire.
For vertical termination
Measure the distance from the stove flue outlet to the ceiling. Add the ceiling thickness, the vertical rise in an attic or
second story, and allow for sufficient vent height above the
roof line. You may use one or two 90° elbows in this vent
configuration. Refer to Vertical Termination Configurations
on Page 16.
NOTE: You may use two 45° elbows in place of a 90° elbow.
You must follow rise to run ratios when using 45° elbows.
The appliance is approved for use with three 90° elbows
maximum or a combination of 90° and 45° elbows up to
a maximum of 270°.
For two-story applications, firestops are required at each
floor level. If an offset is needed in the attic, additional pipe
and elbows will be required.
You may use a chase with a vent termination with exposed
pipe on the exterior of the house. Refer to Installing Vent
System in a Chase.
It is very important that the venting system maintain its balance between the combustion air intake and the flue gas
exhaust. Certain limitations apply to vent configurations
and must be strictly followed.
VS38 Direct Vent Gas Stove
VENTING INSTALLATION INFORMATION
Installing a vent system in an
outside chase
WARNING
A chase is a vertical boxlike structure built to enclose
venting that runs along the outside of a building. A chase
is required for such venting.
Treatment of firestops and construction of
the chase may vary from building type to
building type. These instructions are not
substitutes for the requirements of local
building codes. You must follow all local
building codes.
WARNING
NOTE: When installing in a chase, you should insulate the
chase as you would the outside walls of your home. This
is especially important in cold climates. Insulation should
be considered a combustible material. Maintain proper
clearances to all combustible materials.
10
Always maintain minimum clearances around vent systems. The minimum
clearances to combustibles for horizontal vent pipe are 2" at the top and 1" at
the sides and bottom of the vent system until the pipe penetrates the nearest
vertical wall. A 1" minimum clearance all around the pipe must be maintained.
Do not pack the open air spaces with insulation or other materials. This could
cause high temperatures and may present a fire hazard.

WARNING
INSTALLATION FOR HORIZONTAL TERMINATION
1. Determine the route your horizontal venting will take.
Note: The location of the horizontal vent termination on
the exterior wall must meet all local and national building
codes.
Snorkel terminations are available for terminations requiring a vertical rise on the exterior of the building. Figures
8 and 9. Follow the same installation procedures used for
standard horizontal terminations. If installing the snorkel
termination below grade (basement applications), you must
provide proper drainage to prevent water from entering the
snorkel termination. Figure 9. Do not back fill around the
snorkel termination.
Snorkel
Do not recess vent terminal into a wall or
siding.
2. Rigid vent pipes and fittings have special twist-lock
connections. Assemble the desired combination of pipe
and elbows to the appliance adaptor with pipe seams
oriented towards the wall or floor.
Twist-lock Procedure: The female ends of the pipes
and fittings have three locking lugs (indentations).
These lugs will slide straight into matching slots on
the male end of adjacent pipes and fittings. Push the
pipe sections together and twist one section clockwise
approximately one-quarter turn until the sections are
fully locked. Figure 10

Note: Horizontal runs of vent must be supported every
three (3) feet (914 mm). Use wall straps for this purpose.
3. Attach vent pipeFP1953
assembly to the stove. Set stove in
front of its permanent
rigidlocation
pipe to insure minimum clearances. Mark the wall for a 9Z\x" (241 mm) square hole
(for noncombustible material such as masonry block or
concrete, a 7Z\x" [190 mm] diameter hole is acceptable).
Figure 11. The center of the hole should line up with
the center line of the horizontal rigid vent pipe end. Be
sure to allow for minimum rise. Cut a 9Z\x"x9Z\x" (241

INSTALLATION FOR VERTICAL TERMINATION
1. Determine the route your vertical venting will take. If
ceiling joist, roof rafters or other framing will obstruct the
venting system, consider an offset. Figure 18 to avoid
cutting load bearing members.
NOTE: Pay special attention to these installation instructions
for required clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, etc. Do not pack air spaces with insulation. Also
note maximum vertical rise of the venting system and any
maximum horizontal offset limitations. Offsets must fall
within the parameters shows in Figure 7 on page 12.
2. Set stove in desired location. Drop a plumb line down
from the ceiling to the position of the burner system exit
flue. Mark the center point where the vent will penetrate
the ceiling. Drill a small locating hole a this point.
Drop a plumb line from the inside of the roof to the locating hole in the ceiling. Mark the center point where the
vent will penetrate the roof. Drill a small locating hole
at this point.

VENTING INSTALLATION
FLAT CEILING INSTALLATION
1. Cut a 9Z\x" (241 mm) square hole in the ceiling using the
locating hole as a center point The opening should be
framed to 9Z\x" x 9Z\x" (241 x 241 mm) inside dimensions
as shown in Figure 20 using framing lumber the same
size as the ceiling joist. If the area above the ceiling is
an insulated ceiling or a room, nail firestop from the top
side. This prevents loose insulation from falling into the
required clearance space. Figure 19. Otherwise, install
firestop below the framed hole. The firestop should be
installed with no less than three nails per side. Figure
20.
2. Assemble the desired lengths of pipe and elbows necessary to reach from the burner system flue up through
the firestop. Be sure pipe and elbow connections are
fully twist-locked. Page 13, Figure 10
3. Cut a hole in the roof using the locating hole as a center
point. (Cover any exposed open vent pipes before cutting hole in roof). The 9Z\x" x 9Z\x" (241 x 241 mm) hole
must be measured on the horizontal. Actual length may
be larger depending on the pitch of the roof. There must
be a 1" minimum clearance from the vent pipe to combustible materials. (Insulation should be considered a
combustible material) Frame the opening as shown in
Figure 11 on Page 14.
Nails
4. Connect a section of pipe and extend up through the
hole.
NOTE: If an offset is needed to avoid obstructions, you
must support the vent pipe every three (3) feet. Use wall
straps for this purpose. See Figure 18, page 17. Whenever
possible, use 45° elbows instead of 90° elbows. The 45°
elbow offers less restriction to the flow of the flue gases
and intake air.
5. Place the flashing over the pipe section(s) extending
through the roof. Secure the base of the flashing to
the roof and framing with roofing nails. Be sure roofing
material overlaps the top edge of the flashing as shown
in Figure 18, page 17. There must be a 1" clearance
from the vent pipe to combustible materials.
6. Continue to add pipe sections until the height of the vent
cap meets the minimum building code requirements.
NOTE: You must increase vent height for steep roof
pitches. Nearby trees, adjoining roof lines, steep pitched
roofs, and other similar factors may cause poor draft or
down-drafting in high winds. Increasing the vent height
may solve this problem.
NOTE: If the vent pipe passes through any occupied areas
above the first floor, including storage spaces and closets,
you must enclose pipe. You may frame and sheetrock the
enclosure with standard construction material. Make sure
to meet the minimum allowable clearances to combustibles.
Do not fill any of the required air spaces with insulation. CATHEDRAL CEILING INSTALLATION

IMPORTANT: Review all information on previous page
before planning this installation. Cathedral ceiling
installations can be very tricky.
1. Remove shingles or other roof covering as necessary
to cut the rectangular hole for the support box. Mark the
outline of the cathedral ceiling support box on the roof
sheathing using the locating hole as a center point.
2. Cut the hole 1/­­8" larger than the support box outline.
Figure 21
3. Lower the support box through the hole in the roof until
the bottom of the box extends at least 2" ( mm) below
the ceiling. Figure 21. Align the support box vertically
and horizontally using a level. Temporarily tack the support box in place through the inside walls and into the
roof sheeting.
4. Using tin snips, cut the support box from the top corners
down to the roofline and fold the resulting flaps over the
roof sheeting. Figure 22. Apply a bead of non-hardening
mastic around the top edges of the support box to make
a seal between the box and the roof. Nail in place with
roofing nails. Remove any combustible material that
might be inside the support box.
5. Complete the cathedral ceiling installation by following
the same procedures outlines in Steps 2 through 6 for
Flat Ceiling Installation, Page 17 and above.

CAUTION
For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do not
reduce incoming gas pressure, burner system regulator damage could occur. Install external regulator with the vent
pointing down as shown in Figure 27. Pointing the vent down protects it from freezing rain or sleet.
Use only new black iron or steel pipe.
Internally tinned copper or copper tubing
can be used per National Fuel Code, Section
2.6.3, providing gas meets hydrogen sulfide
limits, and where permitted by local codes.
Gas piping system must be sized to provide
minimum inlet pressure (listed on data
plate) at the maximum flow rate (BTU/hr).
Undue pressure loss will occur if the pipe
is too small.
When using copper of flex connectors use only fittings
approved for gas connections. The gas control inlet is
3/8" NPT.

Figure 28
IMPORTANT: Install main gas valve (equipment shutoff valve)
in an accessible location. The main gas valve is for turning on
or shutting off the gas to the stove.
CAUTION
NOTE : The gas line connection may be made using 1/2" rigid tubing or an approved flex connector.
Since some municipalities have additional local codes it is always best to consult your local
authorities and the current edition of the National Fuel Gas Code ANSI.Z223.1, NFPA54. In Canada
CSA-B149 (1 or 2) Installation Code.
Use pipe joint sealant that is resistant to
liquid petroleum (LP) gas.
Check your building codes for any special requirements for locating equipment shutoff valve to
stoves.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe.
Excess sealant in pipe could result in clogged burner system valves.
We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 28. Locate
sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply
and burner system. Locate sediment trap/drip leg where trapped matter is not likely to freeze. A sediment
trap collects moisture and contaminants and keeps them from going into the burner system gas controls.
If sediment trap/drip leg is not installed or is installed wrong, burner system may not run properly.

clean glass when it is hot. Damage could
occur.
Make sure the gas valve knob is in the “OFF” position. Wait at
least five (5) minutes before start­­-ing maintenance.
Venting system
A qualified agency should examine the venting system annually.
Cleaning glass
Clean the ceramic glass periodically. Condensation will sometimes form on the glass during a cold startup. This is normal
for all gas stoves and stoves. This condensation often attracts
dust and lint to the surface of the glass. The initial paint curing
of the appliance can also leave a slight film on the glass. This
is a temporary problem.
Your should clean the glass after the first two weeks of use. After
that, you should clean the glass no more than two or three times
a season. Use a mild glass cleaner to clean the door. Do not
use abrasive cleaners. They will damage the glass surface.
