DESIGN AND INSTALLATION CONSIDERATIONS FOR -VENTS
When selecting a location for your B-Vent appliance, it is important to evaluate a number of considerations. Modern
construction techniques can create conditions that may not allow your vent to draft properly. This may result in spillage
from your B-Vent appliance, as well as cause other combustion appliances to operate incorrectly.
Tightly sealed construction is important for energy efficiency. Unfortunately, a great deal of effort has been directed to
tightening up sidewall construction, while considerably less attention has been paid to tightening upper portions of the
warm air envelope (insulated ceilings). This has increased the Stack Effect, a condition that increases the negative
pressure generated by the structure. This negative pressure will directly affect the drafting performance of a B-Vent
appliance vent. To minimize the negative pressure generated by stack effect, make certain that all duct work installed in
the attic spaces is sealed airtight. Minimize the number of recessed light fixtures installed in the insulated ceiling and use
sealed recessed light fixtures. inally, make certain the whole house fans and attic access panels are tightly sealed.
These are important design considerations that must be observed during the design and construction stage of the home.
If you desire to put an appliance in your basement, we recommend that you consider a direct vent gas appliance. Basements
always have a significant negative air pressure that causes the B-Vent system to be more susceptible to spillage and cold
flue back drafting. Since direct vent gas appliances are sealed, they are not affected by the negative pressure that exists
in basements.
inally, a B-Vent appliance performs best when the vent (roof termination) is located on the upper half of the roof, especially
when cathedral ceilings are present. Vents that are located on the lower half of the roof realize what is known as lazy flue
and will not draft as well as a vent that is located in the upper portion of the roof. The reason for this is that the stack effect
generated by the overall height of the living spaces inside the house will exceed the draft generated by the vent system.
If you desire to place an appliance in a location where the termination cap would be located on the lower half of a roof;
such as on an outside wall at the base of a cathedral ceiling, we recommend that you consider using a direct vent gas
appliance. This will ensure an appliance that operates correctly.
These properties do not affect just your B-Vent appliance. They can cause any woodburning fireplace as well as any
conventionally vented (B-Vent) gas appliance to operate improperly. Careful planning at this stage of your project will
ensure satisfaction with the operation of your appliance once it is completed.

The G136 Series is a vented gas appliance. While a significant amount of heat is created by the G136, it is not intended
to be and should not be used as a heater.
Typical Vertical Installations
We strongly recommend that you DO NOT install B-
Vent Gas Appliances in strong negative air locations,
such as a basement or a public facility. Living rooms
with cathedral ceilings could be susceptible to a
negative air situation, but such installations can be
overcome through raising the termination,
depending on specific installations. This appliance
uses room air for normal operation and could have
problems establishing a positive draft in a negative
air location. In lieu, we recommend a Direct Vent Gas
Appliance.

E. STEP-BY-STEP INSTALLATION
WARNING!
Before starting, do the following:
. Wear gloves and safety glasses for protection.
2. Keep hand tools in good condition. Sharpen cutting edges and make sure tool handles are secure.
3. Always maintain the minimum air space required to the enclosure to prevent fire.
1. Positioning the as Appliance
This appliance may be placed on either a combustible
or noncombustible continuous, flat surface. If the appli-
ance is installed on combustible flooring other than wood,
a metal panel needs to be installed underneath the ap-
pliance extending its full width and depth. Slide the ap-
pliance into position and level from side-to-side and front-
to-back. Shim with noncombustible material, such as
sheet metal, as necessary.
Secure the appliance by bending out the nailing
flanges located on each side of the appliance and
nailing the appliance to the framing. See igure 4.
2. Termination
Common venting of this gas appliance with other gas
appliances is not allowed in multifamily dwellings.
Possible problems which may occur from common
venting are usually more costly and does not prevent
possible spillage of flue gas products into other
occupied spaces sharing the common vent. Noise is
easily transmitted from one area to another if common
venting is used.
Note: The 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 tempera-
tures and may present the possibility of a fire.
Figure 5
Venting Off The Top of Appliance
Figure 4 - Nailing Flanges
Note: This appliance requires the use of a 5 B-
vent for operation and must be terminated above
the roof line. Never downsize pipe. Follow all B-
vent requirements and installation instructions.
The minimum height of vent installation must be 9 from
the top or 12 from the base of the appliance. Horizontal
run must never exceed 50% of the height of the vent
system as shown in igure 5.
The following figures are the maximum distances
from the base of the appliance, as well as the
minimum air space clearances that must be
maintained during termination of this appliance.
Maximum straight unsupported rise - 25 feet;
maximum horizontal unsupported run - 3 feet; air
space clearances around vertical rise - 1 on all sides;
air space clearances around the horizontal run - 3
on top and 1 on sides and bottom; maximum
height-40 from the base of the appliance. Every 1
of horizontal run requires at least 2 of vertical rise.

12 20356 Rev R 08-03
G136 SERIES INSTALLATION INSTRUCTIONS
a. Assembling Vent Sections
Attach a straight vent section to the top of the
appliance. Elbows directly off the top of the
appliance are allowed but are strongly not
recommended. This may cause the appliance to
operate ineffectively. Secure the attached vent
section to the appliance with the three screws
supplied. Use only B-vent sections.
b. Using Elbows
Elbows exceeding 45 degrees from the vertical
shall be considered horizontal and therefore
adapt horizontal run limitations. Each such elbow
shall be considered the equivalent of 2 feet of
horizontal run. See igure 6.
c. Penetrating the Ceiling
Mark and cut out an opening in the ceiling for the
firestop spacer. rame the opening with the same
size lumber used in the ceiling joists.
d. Installing the Firestop Spacers
irestop spacers must be used whenever the
venting penetrates a ceiling/floor area.
In all situations, firestop spacers are to be nailed
to the ceiling joists from the bottom or appliance
side, EXCEPT when the space above is an
insulated ceiling or attic space. In this situation,
the firestop spacer must be nailed from the top
side to prevent loose insulation from falling into
the required one inch air space around the vent
system.
Install the firestop spacer by positioning and
nailing the four sides of the firestop spacer to the
joists using a minimum of three nails per side.
e. Securing Vent System
Continue assembling the vent sections up
through the firestop spacers as needed. Vent
sections must be locked into position. Elbows
and chimney stabilizers have straps for securing
these parts to joists or rafters.
f. Marking the Exit Point in the Roof
Locate the point where the venting will exit the
roof by plumbing down to the center of the vent
system. Drive a nail up through the roof to mark
the center. See igure 7.
Note: Be sure to provide intermediate support for the
vent during construction and check to be sure inadvert-
ent loading has not dislodged the vent from the appli-
ance or any vent joint.
WARNING!
When vent sections exceeding 3 feet in length are
installed between an offset and return, structural
support must be provided to reduce off-center load-
ing and prevent vent sections from separating at the
vent joints. Follow all B-Vent manufacturer guide-
lines.

Minimum Termination Height
g. Cutting Out the Hole in the Roof
Measure to either side of the nail and mark that
7 x 7 opening required (must meet minimum
clearances per venting requirements). 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 section and
the roof.
h. Install Roof Flashing or Site-Constructed
Chase Top
Position a roof flashing or a site-constructed
chase to and secure into place.
i. Assembling Vent Sections
Continue to add vent sections through the roof
opening, maintaining at least a one inch air space
clearance.
j. Termination Cap
Major building codes specify a minimum
termination height above the roof top depending
on the roof pitch. It is strongly recommended that
the cap should be at least 2 higher than anything
within 10 of it, and a minimum of 3 out of the
roof. This will help to ensure the best air flow.
) Unlisted Cap
If you are using an unlisted termination cap
and your vent section is at least 8 feet from
the vertical wall, follow igure 8 and Table 1
to determine the allowable termination
height and location.
Measure the roof pitch. Roof pitch is X/12 as
shown in igure 8. ind your roof pitch in
Table 1 to determine the minimum height the
termination cap must be located from the
point where the vent section penetrates the
roof (H in igure 8).
2) Listed Cap
If you are using a listed termination cap, you
must follow the manufacturers installation
instructions for minimum clearances to roof
and any obstructions.
These termination heights are necessary in the
interest of safety and do not guarantee proper
operation. Trees, buildings, adjoining roof lines,
adverse wind conditions, etc. may create a need
for a taller roof termination should down drafting
occur.
To install the termination cap, slide the cap vent
sections into the vent pipe. Secure the cap using
the screws provided.

G136 SERIES INSTALLATION INSTRUCTIONS
k. Checking the Vent System
Periodically the venting system should be tested
to assure proper operation. This can be done with
a match while the appliance is operating.
Hold a lighted match at the top edge of the
appliance opening. If the flames and smoke
remain upright, ventilation is acceptable. If the
flames and smoke are drawn into the appliance,
this means ventilation is good. If the flames and
smoke are forced away from the appliance, this
may indicate a ventilation blockage or down draft
resulting in gas spillage into your home. If this
occurs, turn off the appliance and do not burn it
until it has been inspected by a qualified service
person.
If you have installed optional doors, close the doors
and conduct the test following the same instructions
above. See igure 9.
3. Double Check Venting
When construction of the entire vent system has been
completed, double check to make sure all venting
pipes and termination caps are unobstructed.
4. as Line Installation
Install the gas line piping into the right side of the gas
appliance. A manual shutoff valve (supplied) should
always be used. See igure 10.
5. as Line Connection
The appliance is provided with a stainless steel flexible
connector and a listed (and Commonwealth of
Massachusetts approved) T-handle manual shutoff
valve. See igure 10. The incoming gas line should be
piped into the valve compartment and connected to
the 1/2 IP connection provided on the manual shutoff
valve. See igure 10 to connected the gas line.
Optional: Seal around the gas line to prevent cold air
leakage.
All connections must be tightened and checked for
leaks with a soap and water solution or a leak detector.
Bleed the gas line to extract any air that may have
been trapped inside the pipe.
Figure 9
Testing Ventilation
Note: Have the gas supply line installed in
accordance with building codes by a qualified
installer approved and/or licensed as required by
the locality. In the Commonwealth of Massachusetts,
installation must be performed by a licensed plumber
or gas fitter.

08-03 20356 Rev R 15
G136 SERIES INSTALLATION INSTRUCTIONS
Note: The appliance and its manual shutoff valve must
be disconnected from the gas supply piping system dur-
ing any pressure testing of that system at test pressures
in excess of 1/2 psi (3.5 kPa). The appliance must be
isolated from the gas supply piping system by closing
its manual shutoff valve during any pressure testing of
the gas supply piping system at test pressures equal to
or less than 1/2 psi (3.5 kPa).
Note: Although each appliance is leak tested in the fac-
tory, it is mandatory during the first burn for you to check
for leaks. These may occur due to handling, shipping,
installation and the like and are beyond the control of
Hearth & Home Technologies. Every joint, including the

9. Outside Air Kit Installation (strongly
recommended)
Many possible locations on either side of the appliance
are available for your outside air inlet. igure 16
demonstrates two possible locations. The outside air
kit can terminate at any level with the exception that it
must terminate at least one foot below the vent
termination cap. See igure 16. Be sure to check vent
height requirements for the appliance before attempting
any basement location. The outside air kit inlet thimble
should be positioned at least four feet above the ground
level in a manner that will not allow snow, leaves, etc.
to block the inlet. Ducting must be ordered separately.
The vent inlet must be connected to an air supply
outside of the building and must not exit higher than
the building soffit.
WARNING!
When locating the appliance in a space
projecting into a garage, the outside air
must not be taken from the garage space.
Exhaust products of gasoline engines are
hazardous. Do not install outside air ducts
such that the air may be drawn from attic
spaces, basements, or above the roofing
where other heating appliances or fans and
chimneys, exhaust or utilize air.
WARNING!
Significant cold air may infiltrate through
the duct or other parts of this system. To
guard against this, check for light leaks with
a flashlight and seal these with duct tape
and/or insulation.

10. Finishing
Install the hood by using the three screws provided. See
igure 19 for the position of the hood.
When finishing the face of the appliance, combustible
material may be brought up to the sides of the
appliance, but must never overlap onto the black metal.
The black metal may be covered with noncombustible
material only.
Note: The placement of the logs, lava rock and rock wool
is very critical to the looks of the appliance during its op-
eration. Please take time during this portion of the setup
to achieve the best appearance.
Note: You cannot cover any portion of the hood or
control access panel on this appliance, as this may
create a fire hazard. See igure 19 for hood and con-
trol access panel locations.
Check the operation of the air kit damper by pulling
the control arm out to a fully open position,
catching the last notch of the control arm to lock it
in place. Push the control arm inward to fully close
the damper. Intermediate notches in the control
arm can be used to adjust incoming air.
c. Cutting the Exterior Hole
Mark and cut out a 4 diameter hole in the exterior
wall for air entry. This hole should allow framing
(minimum of two sides) so the 4 tube assembly
may be nailed into position, flush with the exterior
wall of the building.
d. Attaching the Flexible Duct
Assemble the flexible duct between the damper
assembly and the tube assembly. Secure it into
position with the provided clamp bands and
screws.
After applying the finishing material, a noncombustible
sealant, one-half inch wide maximum, must be used
to close off any gaps at the top and sides between
the appliance and finishing to prevent cold air leaks.
See igure 19.
A combustible mantel may be installed at a minimum
of 42 inches above the base of the appliance.
11. Positioning the Logs
Place the medium sized log in the back log brackets
as shown in igure 20. Place the larger log in front.
The front log is shaped to cover the burner tube. or
this reason, it has an extra piece which protrudes from
one end of the log. Be sure this piece is positioned to
the left side of the firebox. See igure 21.
Lay the two smaller logs across the larger logs, as
shown in igure 22, making sure they are positioned
so they do not cover (come into direct contact with)
the flames. If the logs impinge the flame (set directly
over the flame) excessive carbon can occur.
12. Placing the Lava Rock
Spread the lava rock in the tray just in front of the logs,
covering the front burner tube. Depending on your
taste, additional lava rock may be placed on the floor
of the burn chamber around the tray.
