monoxide. These may include pregnant women, people with
heart or lung disease, are anemic, anyone under the infl uence
of alcohol, and those at high altitude.

IMPORTANT: Read this owners manual carefully

and completely before trying to assemble, operate,
or service this fi replace. Improper use of this
fi replace can cause serious injury or death from
burns, fi re, explosion, electrical shock, and carbon
monoxide poisoning.

General Safety Concerns

1. If you smell gas

O Shut off gas supply.
O Do not try to light any appliance.
O Do not touch any electrical switch; do not use any

phone in your building.

O immediately call your gas supplier from a neighbor’s

phone. Follow the gas supplier’s instructions.

O If you cannot reach your gas supplier, call the fi re

department.

2. This fi replace shall not be installed in a bedroom or

bathroom.

3. Never install the fi replace

O In a recreational vehicle.
O Where curtains, furniture, clothing, or other fl ammable

objects are less than 36 inches from the front, top, or
sides of the fi replace.

to smoke, turn off fi replace and call a qualifi ed service
person.

7. Avoid any drafts that alter burner fl ame patterns. Do not

allow fans to blow directly into the fi replace. Do not place
a blower inside burn area of the fi rebox. Ceiling fans may
create drafts that alter burner fl ame patterns. Soot build-up
and improper burning will occur. Soot build-up can settle on
household surfaces outside the fi replace.

8. This fi replace needs fresh air ventilation to run properly.

The Vent free decorative gas log set must have an
oxygen depletion sensor (ODS) pilot light safety system.
The ODS shuts down the fi replace if not enough fresh
air is available. See Air for Combustion and Ventilation,
page 8. If the fi replace keeps shutting off, see appliance
manufacturers’ troubleshooting instructions.

9. Do not run fi replace

O Where fl ammable liquids or vapors are used or stored.
O Under dusty conditions.

10. Do not use this fi replace to cook food or burn paper or
other objects.

11. Never place any objects in the fi replace or on logs.

12. Fireplace screens must be provided and are to be closed
before operating the decorative room heater. If doors are
installed, they must be open during operation. Fireplace
front and screen become very hot when running fi replace.
Keep children and adults away from hot surfaces to avoid
burns or clothing ignition. The fi replace will remain hot
for a time after shut down. Allow surfaces to cool before
touching.

13. Carefully supervise young children when they are in the
room with the fi replace.

14. Do not use fi replace if any part has been exposed to or
under water. Immediately call a qualifi ed service technician
to inspect the fi replace and to replace any part of the control
system and gas control which has been under water.

Location

Location

Note: You may need to provide combustion and ventilation air

from an outside source to adequately satisfy local codes so
avoid installing a combustion air inlet where the opening could
be blocked by snow, bushes or other obstacles. Note that the
access for outside air inlet is located on the right hand side of
the fi replace.

Figure 3

Projected installations can extend any distance into the room.

A projection may be ideal for a new addition on an existing,
fi nished wall.

Corner installations make use of space that may not normally
be used and provides a wider and more effi cient range for heat
disbursement.

An internal wall installation provides a discreet option for
room separation and can also be ideal as an addition to an
existing wall.

IMPORTANT: Vent-free heaters add moisture to the air. Installing
a fi replace in rooms without enough ventilation air may cause
mildew to form from too much moisture.

IMPORTANT: Make sure the fi replace is level. If the fi replace is
not level, the log set will not work properly.

Attention: You will need a building permit to install a Burntech
fireplace. Check with the local jurisdiction before you get
started.

Supporting Floor Systems

Floor Framing

It is important to take into consideration that the load for the
Burntech Fireplace is considerable, but, more important, that it
is a dead load that will have to be absorbed by a relatively
small amount of existing fl oor space.

It is the ultimate responsibility of the installer to ensure that
proper concrete slab supports are used.

WARNING to the licensed design professional and/or building
contractor: It is your responsibility to be certain that the
Burntech can be properly supported by the combustible fl oor
system on which the fi replace will rest.

For fi replace support foundations installed on concrete refer to
Appendix I and II (pages 17 & 18) for specifi c instructions.

Rebar locations

Lay-out the position of the fi replace and drill holes where
the rebar will be located. Secure the #3 rebar 4 inches into the
concrete foundation with ITW Epoxy or Simpson Epoxy. Follow
manufacturer’s instructions for installation of rebar into slab.

Wood Floor

Anchorage of fi replace to wood fl oor construction is required.
Refer to Figure 8 for anchorage dimensions. Four anchors are
required to attach to the sub-fl ooring framing.

Crawl Space or Upper Floor:

For installation of fi rebox over combustible crawl spaces or
upper fl oors, anchorage of the fi rebox is required. Illustrations
of examples of possible anchorage methods are shown in
Figures 5 thru 7 depending upon the type of fl oor framing. Final
method of anchorage is to be determined by licensed design
professional.

6

For conventional framing, where the fl oor joists are parallel
with the sides of the fi rebox, the addition of fl oor joists to align
with the anchor brackets allows the brackets to be directly
connected to the fl oor joists.

Note that additional fl oor joists may be required to support
the weight of the fi rebox and chimney. Where the fl oor joists run
parallel to the front of the fi rebox, anchorage can be accomplished
in like manner as shown in Figure 5 using blocking between the
fl oor joist.

For fl oors supported by I-Joists, the method of anchorage is
illustrated in Figures 6 and 7. Figure 10 illustrates the general
arrangement of anchorage to fl oor framing.

The Importance of Clearances

Warning to the structural engineer and/or building contractor: It
is your responsibility to be certain that the Burntech can be
properly supported by the combustible fl

oor system on which
the fi replace will rest. Be advised that this engineering
equation will be in addition to any live or dead weights that the
fl oor has to carry.

Clearances to Combustibles

Nothing is more important than paying strict attention to
giving clearance between fi replace surfaces and surrounding
“combustibles” the most common of which are:

ODrywall

OWood fl ooring

OPlywood sub-fl ooring

OFraming materials

OParticle board

OMill board

OPlywood paneling

Required Clearances are:

Unit front, sides, rear: .......................................... 0"

Combustible Floor: .............................................0"

Combustible Sheathing above opening top: ....... 8" (200 mm)

Sheathing or trim to opening sides: ....................8" (200 mm)

Clearance to combustible trim are those distances required
to ensure that combustible mantle and facing material will not
be exposed to excessive heat while the unit is operating.

These clearances should be adequate to prevent
discoloration or warping of trim facings due to heat. However,
circumstances unique to each installation create variables that
may be beyond the scope of this manual. Therefore be sure
to follow gas log appliance manufacturer’s explicit installation
instructions regarding all minimum trim facing, mantle height
and side wall clearance requirements.

Figure 13

The Burntech Vent-Free fi replace may be installed at “zero

clearance” to plywood sheathing and to uninsulated wood
framing members at the unit bottom, sides, rear and top when
used for enclosing any listed vent-free gas-fi red log set with
maximum heat input ratings up to 40,000 Btu/hr. However,
when a Vent-Free fi replace is to be installed on carpeting,
wood fl ooring, or any combustible material other than tile or
concrete, the Vent-Free fi replace shall then be installed on a

metal or wood platform extending the full width and depth of
the Vent-Free fi replace.

Clearance to Combustible Trim:

Burntech Vent-Free Fireplaces are designed to be custom fi
nished with facing trim and mantle to be an owner option.
However, all such trim material must meet standard fi replace
code requirements.

Non-combustible facing material must be applied to a
minimum of eight inches (8”) beyond the sides of the fi nished
opening of the Vent-Free fi replace and non-combustible facing
material must cover a minimum of twelve inches (12”) above
the fi nished opening of the installed unit.

Parts of the combustible mantle assembly located above
and projecting more than one and one-half inches (1-1/2”)
inches from the fi rebox opening shall be kept at least twelve
inches (12”) from the top of the opening.

Mantle shelves with horizontal projection of ten inches (10”)
from the face of the fi replace must be held to a minimum vertical

distance of twenty inches (20”) from the top of the fi nished
fi replace opening.

Note: Mantle height clearances may vary among gas log
appliance manufacturers or with the use of fi rebox canopies.

Be sure to follow the gas log appliance manufacturer’s
explicit installation instructions for mantle height clearance
requirements.

9

Interior Wall Materials:

Air for Combustion and Ventilation

Wall materials, such as drywall, should be set fl ush with
the rough front face of the Vent-Free fi replace. This will allow
for placement of required non-combustible surround material in
such a way that the surround material can lay fl at against the

fi nished wall surface and also align with the leading edge of the
fi re brick interior of the Vent-Free fi replace (see Figure 15).

Trim Facings:

Parts of the combustible mantle assembly located along
the sides of the fi rebox opening, which project more than one
and one-half inches (1-1/2”) from the face of the fi replace, shall
be kept at least eight inches (8”) from the fi rebox opening.

Adjoining Room Walls:

Interior wall surfaces of adjoining room walls must be at a
minimum horizontal measure of twenty four inches (24”) away
from the fi nished opening of the Vent-Free fi replace.

Air for Combustion and Ventilation

Energy effi cient homes require homes to be airtight but at the
same time provide suffi cient fresh air to breathe. Fresh air
enters the home through air conditioning duct vents, around
doors and windows but also must provide enough fresh air for
proper combustion on all fuel-burning appliances in the home.
Exhaust fans, fi replaces, clothes dryers, and fuel-burning
appliances draw air from the house to operate. You must provide
adequate fresh air for these appliances. This will insure proper
venting of vented fuel-burning appliances.

Providing Adequate Ventilation

In accordance with the National Fuel Gas Code NFPA 54/ANSI
Z223.1, Section 5.3, Air for Combustion and Ventilation, all
spaces in homes fall into one of the three following ventilation
classifi cations:

1. Unusually Tight Construction

2. Unconfi ned Space

3. Confi ned Space

The following information will help you classify your space and
provide adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and windows may provide
enough fresh air for combustion and ventilation. However,
in homes of unusually tight construction, you must provide
additional fresh air. Unusually tight construction is defi ned as
construction where:

a. Walls and ceilings exposed to the outside atmosphere have

a continuous water vapor retarder with a rating of one perm*
or less with openings gasketed or sealed and...

b. Weather stripping has been added on openable windows and

doors and...

c. Caulking or sealants are applied to areas such as joints

around window and door frames, between sole plates and
fl oors, between wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas lines, and
other openings.

* A perm is a unit of permeance or water vapor transmission,
the US perm-inch is defi ned as the passage of 1 grain of vapor
through 1 square foot of 1 inch thick material in 1 hour under a
pressure difference of 1 inch of mercury.

If your home meets all the three criteria above, you must provide
additional fresh air.

10

Unconfi ned Space

An unconfi ned space has a minimum total air volume of
50 cu.ft. (cubic feet) for each 1,000 Btu/Hr input rating of all
appliances in the total space (cu.ft. = length x width x height
of space). Include adjoining rooms only if there are doorless
passageways or ventilation grills between the rooms. If the Btu
per 50 cu.ft. is less than 1,000 Btu/Hr, then fresh air will be
provided by the natural air fl ow into the house.

Confi ned Space

A confi ned space has an air volume of less than 50 cu.ft. for
each 1,000 Btu/Hr input rating of all appliances in the space (cu.
ft. = length x width x height of space). Include adjoining rooms
only if there are door less passageways or ventilation grills
between the rooms.

Determining Total Air Volume

Use this work sheet to determine if you have a confi ned
or unconfi ned space. The space to be considered includes not
only the room in which you will install the fi replace but also any
adjoining rooms with ventilation grills between them or door
less passageways.

1. Determine the total volume of your space

L x W x H = _______ cu.ft.
Example: Space size = 20 ft. long x 20 ft. wide x 8 ft. high
(ceiling height) = 3,200 cu.ft.
If adjoining ventilation to adjoining room is supplied with
grills or openings, add the volume of these rooms to the total
volume of the space.

2. Divide the space volume by 50 cu.ft. to determine the

maximum Btu/Hr the space can support.
_______ cu.ft. (volume of space)
50 cu ft. = (Maximum Btu/Hr the space can support)
Example: 3200 cu ft. (Volume of space) / 50 cu. Ft. = 64.0 or
64,000 (maximum Btu/Hr the space can support.)

3. Add the Btu/Hr of all fuel burning appliances in the space.

Vent-free fi replace _______ Btu/hr
Gas water heater* _______ Btu/hr
Gas furnace _______ Btu/hr
Vented gas heater _______ Btu/hr
Gas fi replace logs _______ Btu/hr
Other gas appliances* _______ Btu/hr

Total = _______ Btu/hr

4. Compare the maximum Btu/Hr the space can support with
the actual amount of Btu/Hr used.

_________ Btu/Hr (maximum the space can support)
_________ Btu/Hr (actual amount of Btu/Hr used)

Example:
64,000 Btu/Hr (maximum the space can support)
76,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the previous example was a confi ned space
because the actual Btu/Hr used was more than the maximum
Btu/Hr the space could support. If you fi nd you have a Confi ned
Space, you must provide additional fresh air. Your options are
as follows:

a) Re-work worksheet, adding the space of an adjoining room

that may not have qualifi ed for the extra volume. If the extra
space provides enough volume to convert the area to an
unconfi ned space, remove door to adjoining room or add
ventilation grills between rooms.

b) Vent room directly to the outdoors.

c) Install a lower Btu/Hr gas log (if lower Btu/Hr size makes

room unconfi ned).

If the actual Btu/Hr used is less than the maximum Btu/Hr the
space can support, the space is an unconfi ned space. You will
need no additional fresh air ventilation.

WARNING: If the area in which the heater may be operated
is smaller than that defi ned as an unconfi ned space, provide
adequate combustion and ventilation air by one of the methods
described in the National Fuel Gas Code, ANSI Z223.1 Section

5.3 or applicable local codes.

Local codes may have stricter defi nitions for confi ned space
and/or for unusually tight construction. Installing our optional
outside air kit may allow the space to be classifi ed as not being
unusually tight or being an unconfi ned space. Check you local
codes.

IMPORTANT: Do not provide openings for inlet or outlet air
into an attic if the attic has a thermostat-controlled power vent.
Heated air entering the attic will activate the power vent.

Example: Gas water heater 40,000 Btu/hr

Vent-free fi replace +36,000 Btu/hr

Total = 76,000 Btu/hr

* Do not include direct-vented gas appliances. Direct vent draws
combustion air from the outdoors and vents to the outdoors.

Important Pre-installation Information

Important Pre-installation Information

Overview

You will find that the Burntech Fireplace is designed for
complete assembly at your construction site with all necessary
items delivered consisting of interlocking precast parts, 50 lbs.
of Burntech mortar and rebar.

The parts of the fi replace are made of Burntech’s incredibly
strong blend of specialty cement and a lightweight aggregate.

The design of the fi replace calls for the installation of a refractory
fi re brick liner. This should be a minimum of 1-1/8” thick. The
liner will be applied within the walls of the fi rebox. Modular fi
rebrick panels are also available from Burntech.

Additional Materials Required:

1) Ready-Mix concrete - 2 cu.ft.

SURFACE CRACKS - The Burntech FIREPLACES are
manufactured using high quality materials. During the drying

process, surface cracking may occur. These small cracks
(under 1/16” will not affect the fi replace safety or
performance). During the assembly process, fi ll surface
cracks with thin-set mortar and brush when drying for a
smooth surface fi nish.

Leveling and Aligning Components:

It is important to assemble all Vent-Free fi replace components
fl ush, level and square. Since it is not intended that mortar

be used to lay a mortar joint of any measurable thickness as
is typical when laying brick or concrete block, adjustments in
component height and level alignments are accomplished with
the use of small shims. These shims can be tapped into
place to level and align components. Once the Burntech
Mortar is set, the shims must be removed completely.
Be sure to re-grout any and all gaps where shims have been
inserted and then removed or where contact surfaces have
been separated by shim leveling.

Field Assembly Procedures

1) Mixing the BURNTECH mortar – You will require a 50 lb.
bucket of BURNTECH mortar which will be more than
enough to adequately affi x all the fi replace components,
one to the next. The mortar is premixed and dry and is to
be used to adhere all the fi replace components. Be sure to
use clean water and work it up into a mixture that is pasty
but not lumpy. If it is too thin, the components will not
adhere. Some trial and error may be necessary. You will
want to apply the mixture with a standard grout bag.

2) Moisten all surfaces which will have grout applied prior
to assembly. This will minimize shrinkage and cracks
developing in the joint areas. Best way to accomplish this is
with a bucket of water and a large sponge. Dip sponge into
water and apply a liberal amount of water to the grout joint
surface several minutes before the part is to be assembled.
The water will absorb into the surface allowing the grout to
properly cure.

3) Assembly of the Components – Once you have found the
proper consistency of the mixture, load it into the grout bag

and then place the components together applying the mixture
directly to the components where they come together. As a
rule, you can fi gure that you should lay down about ½” (one-
half inch) of a thread of mortar. The line of mortar should be
approximately ½” (one-half inch) away from all the edges of
each separate component.

The mortar has a considerable amount of holding power so
do not overload the components with too much mortar.

4) You will notice that some mortar will “ooze out” when you
place the next component on top of or next to the component
you previously place. This is to be expected – it means the
two pieces have properly bonded -- and you will want to
swipe the excess away with a trowel. It is never intended
that the surfaces of the Burntech components are to be
completely covered with mortar.

5) Do not apply the mortar in thick bands even if the component
you are working with is larger than the rest. You will want to
apply “stripes” of mortar in these situations.

6) Making Sure Components Are Level – It is extremely
important that you pay careful attention to how you are
assembling the Burntech. Since every component builds on
the next, it is critical, that from the beginning, you are
checking that the components are fi tting together to be
level and fl ush. If you have to make any kind of an
adjustment, do not try to do it “by loading an opening” with
mortar. That is completely unacceptable, resulting in a fi
replace that will not be plumb or level. What you are
advised to do is make use of shims. You will fi nd these
supplied with the Burntech and you can nudge them in
between openings to achieve the precision you need in
making component adjustments.

Once you have removed the shims, you will want to cover

7)
any gaps that may have resulted with the grout.

Warning: All surfaces where grout is applied must
have water sponged on several minutes prior to
assembly. This will minimize cracking of grout joint
and provide maximum strength.

Note - Wipe excess water from surface prior to applying grout.

This will help grout to adhere to surface during assembly.

Warning: All surfaces where grout is applied must have water
sponged on several minutes prior to assembly. This will minimize
cracking of grout joint and provide maximum strength.

Place the Burntech Fireplace hearth base on top of your non­combustible fl oor. For concrete slabs, supporting fl oor needs to
be rated at ASTM 90.

and you are working on the top rear fi rebox, check that
your work is level. If you need to, you can make some
adjustments in the top surface of the box assembly
simply by using shims. Once you are satisfi ed with the
degree of levelness, you can address any gap that may
have occurred with an appropriate amount of mortar.

Although you are cautioned to use Burntech mortar
sparingly because it does have such holding power, you
should look over the fi

rebox assembly at the end and fi ll
any gaps with mortar especially at joint connections.
Adjustments must be made to ensure the fi replace is level
and square while the mortar is still wet.

If you would prefer to have a raised hearth, the Vent-Free box
can be raised to the desired height using wood studs or concrete
blocks.

Gas Piping Installation

The provision for installation of a gas pipe is only for
connection to a Vent free decorative gas log sets meeting
standard ANSI Z21.11.2

Figure 26

Concrete Block

Familiarize yourself with requirements for installation as
outlined by the National Fuel Gas Code, ANSI Z223.1.
This gas pipe provision must only be connected to an
approved vent-free gas log heater certifi ed to ANSI Z21.11.2
heater standard. Check local building codes for specifi c pipe
and material requirements.

1) Gas piping can be routed from the fl oor, rear or side walls.
With a masonry drill, follow the instructions from the gas
appliance manufacturer. Any wires must be routed through
separate conduit. Make sure provisions are made for access
to manual shut-off valve.

For a “fl ush hearth” (fi replace fl oor fl ush with the room’s

fl oor) the base plate can be omitted from the assembly and the
fi rebox walls built directly on the concrete support slab. The
fi re brick fl oor of the fi rebox is then set directly to the concrete

support slab. This makes the fi replace fi nished fi re brick fl oor
approximately one and one-half inches (1-1/2”) above the top
of the concrete support slab.

2) After routing piping, fi ll hole around pipe with BURNTECH
mortar.

Electrical Line Feed

Electrical line feed can be routed through the Standard
fi rebox back wall, side walls or fl oor by drilling an appropriately
sized hole using a masonry drill bit. Be sure to follow the
Vent free decorative gas log Manufacturer’s explicit electrical
line connection instructions for vented masonry fi replace
installations.

NOTE: Gas line and electric line must be routed through
separate access holes.

Initial Fireplace Operation

It is required that the interior sides, rear and bottom be lined
with minimum 1-1/8” thick fi rebrick.
firebrick liner walls can make the installation easier.

All required through-wall accesses (gas and electrical
line feeds and combustion air supply access holes) should be
drilled before the required fi re brick lining is installed.

Modular Firebrick Lining

If using our Burntech Firebrick Liners, simply use an extra
bucket of mortar. Install Hearth Liner fi rst, rear next and sides
last. Consider if brackets for grates will be required, also if pre­drilling is required for gas lines, electrical or if the outside
combustion air kit is to be installed.

The following Firebrick Patterns are available from Burntech:

Follow the gas appliance manufacturers’ requirements
for lighting and operating your vent free log. When fi rst operating
the fi replace, open a window in the room to allow smells created
from the heater and fi replace curing.

We suggest operating the heater for several 30 minute
intervals allowing the fi replace to cool for an hour in between.
This will allow any moisture in the brick and fi replace to
escape.

Keep in mind that it may require several operations
to completely remove any smell from the operation of a vent­free heater and fi replace. If this condition continues, contact
your gas appliance dealer to inspect the gas heater for proper
operation.
