Required Gas Pressure
The minimum inlet gas supply pressure for the purpose of
input adjustment is 5” of water column (w.c.) for natural gas.
The maximum inlet gas supply pressure is 10.5” w.c. for
natural gas. The minimum inlet gas supply pressure for the
purpose of input adjustment is 11” of water column (w.c.) for
propane gas. The maximum inlet gas supply pressure is 13”
w.c. for propane gas.
Testing the Gas Supply System
The gas replace and its required individual shut-off valve
must be disconnected from the gas supply piping system
while performing any tests of the piping system at pressures in
excess of 1/2 psig.
The gas replace must be isolated from the gas supply
piping system by closing its individual manual shut-off valve
during any pressure testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig.
This is accomplished by closing the gas supply line valve
required by NFPA 54.
A replace screen must be replaced after service and be
in place when the appliance is in operation and, unless other
provisions are provided, the screen shall have an opening for
introduction of combustion air.
When glass replace doors are used, operate the gas
replace with the doors open. Use only doors rated for this
appliance.

Clearance to Combustibles
Burntech® Fireplace & Chimney Systems
The distance to be maintained from the surfaces of the
replace to combustibles must be observed. Below is a list of
the most common combustible materials to name a few:
Drywall Wood ooring Plywood
Sub-ooring Wood Framing Particle board
Mill board Plywood paneling
Maintain the following minimum clearances:
Unit front, sides, rear 0” 0
Combustible oor 0” 0
Sheathing or trim to opening sides
Combustible sheathing above opening top
Mantel above opening
Opening to side wall
Insulation from rebox
Due to high temperatures, never install this replace in a
recreational vehicle, in high trafc areas, drafty areas, or
where curtains, furniture, clothing, or other ammable objects
are less than 36” from the front or side and 42” from the top of
the replace.
CAUTION: This gas replace attains high temperatures. Keep
children and adults away from hot surfaces to avoid ignition of
clothing and/or burns. Even after the replace is shutdown it
will remain hot for a time afterward. Allow the surface to cool
before touching it.
Carefully supervise young children when they are in the room
with the replace.
All replace openings for both combustion air and exhaust
must remain open and unobstructed at all times when the
replace is in operation.
The Burntech® replace has been designed, tested and
approved for zero clearance to combustible oors.
Be certain that the Burntech® replace is installed with the
nished re brick oor of the replace so that it is at least 4-1/2”
(four and a half inches) above the combustible oor system.
Warning to the structural engineer and/or building contractor:
It is your responsibility to be certain that the replace can be
properly supported by the combustible oor system on which
the replace will rest. Be advised that this engineering equation
will be in addition to any live or dead weights that the oor has
to carry.

Before Getting Started…
Even if you consider yourself an expert in the field of
fireplace installation, we at Burntech® caution you to take the
time to totally familiarize yourself with the instructions to
follow.
We can assure you that there will be information that will
make the installation go smoother and, above all, safer, for
everyone concerned. At the least, reading these procedures will
save you time and, at the most, it will prevent any malfunction
that could result in property damage or serious injury.
Do not start the installation until you have checked out all
the local, regional, state and national rulings, laws and codes
as they apply to replaces and replace installations. Every
community is different so do not assume that because you
know the requirements for one locality, it will be the same in
the next. Avoid bureaucratic hassles and do your homework
WELL BEFORE you start your project!
The Burntech® gas fireplace is designed to be installed
1)
with properly sized B-vent metal chimney or "Class A" UL
103 chimney. BVent chimney or “Class A” chimney
systems must be used on all Burntech BVent Fireplace
systems. Note that the chimney system must always vent
to the outside of the building.
This Burntech® replace is intended as a supplemental heat
2)
source only. It is not intended as a primary heat source.
It is the responsibility of the contractor installer (not the
3)
manufacturer) to ensure that adequate combustion air is
provided for proper function of this replace. Fireplaces
take up a large volume of replacement air from outside the
house and if the house is of airtight construction,
dangerous gas spillage may occur if proper draft is not
achieved.
There are many conditions beyond a manufacturer’s
4)
control when it comes to the operation of the fireplace.
The manufacturer cannot be responsible for spillage free
operation, nor can the manufacturer take on the
responsibility for problems with surrounding construction;
chimneys that have not been built at the right heights;
system drafts caused by faulty mechanical systems;
adverse weather conditions or any other inclement
environmental situations.
Inspect all replace & chimney components for evidence
5)
of damage prior to starting installation. Consult your local
distributor for replacement parts if necessary.
Under no circumstances should you make any adjustments
6)
or modications to the chimney system during the
installation procedure. If you do, you are not only liable
for negating the warranty, but you could very well cause a
serious malfunction of the replace. You must follow these
chimney instructions.
Chimney System Heights
When installed, the maximum overall height of the Fireplace is
40’-0” (forty feet). The minimum installed height of the
completed replace is 14’ 0” (fourteen feet), given that the
chimney is straight. If the chimney includes one or more offset
sections, the measurement is 17’ 0” (seventeen feet).

Supporting Floor Systems
I-Joist
I-JOISTS
Anchor
Brackets
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 oor
system on which the replace will rest.
For replace support foundations installed on concrete refer to
Appendix I and II (pages 31 & 32) for specic instructions.
Rebar locations
Lay-out the position of the 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 replace to wood oor construction is required.
Refer to Figure 9 for anchorage dimensions. Four anchors are
required to attach to the sub-ooring framing.
Crawl Space or Upper Floor:
For installation of rebox over combustible crawl spaces or
upper oors, anchorage of the rebox is required. Illustrations
of examples of possible anchorage methods are shown in
Figures 6 thru 8 depending upon the type of oor framing. Final
method of anchorage is to be determined by licensed design
professional.
For conventional framing, where the oor joists are parallel
with the sides of the rebox, the addition of oor joists to align
with the anchor brackets allows the brackets to be directly
connected to the oor joists.

Note that additional oor joists may be required to support
the weight of the rebox and chimney. Where the oor joists
run parallel to the front of the rebox, anchorage can be
accomplished in like manner as shown in Figure 6 using
blocking between the oor joist.
For oors supported by I-Joists, the method of anchorage is
illustrated in Figures 7 and 8. Figure 11 illustrates the general
arrangement of anchorage to oor framing.
It is important to take into consideration that the load for
the Burntech® Fireplace must be considered as additional
dead load that will have to be supported by the oor framing.
Additional oor joists or I-joists may be required as determined
by the licensed design professional.
The dead weights for the replace are noted in Table I. It is
the task and responsibility of the general contractor/installer
to see that the proper reinforcement for weight loads are
made by a licensed design professional prior to the replace
installation.
As stated above, it is desirable to place additional framing
for alignment of anchor rods. Refer to Figure 9 for anchor rod
locations.

What You Will Need
You will nd that the Burntech® Fireplace is designed to be
completely assembled on-site, consisting of interlocking
precast parts. The parts of the replace are made of
Burntech®’s incredibly strong blend of specialty cement and a
light weight aggregate.
IMPORTANT! When applying mortar, it is imperative that the
concrete blocks be maintained moist (not soaking) so they don’t
absorb the water out of the mortar and cause adhesion to fail.
Frequently run a damp sponge to the parts before mortar is
applied!
The installation of an anchor plate/damper is required but not
supplied. You may purchase it from any chimney manufacturer
or Burntech®. Also, an optional combustion air inlet BFP4-AK
can be obtained from Burntech®.
Refractory Firebrick Liners also need to be installed. These
should be a minimum of 1-1/8” (one and one-eight inches) thick.
The liner will be applied within the walls and hearth area of the
rebox. These are available from Burntech®. See page 27.
SURFACE CRACKS - The Burntech® replaces are
manufactured using high quality materials. During the
drying process, surface cracking may occur. These small
cracks (under 1/16” will not affect the replace safety or
performance). During the assembly process, ll surface
cracks with thin-set mortar and brush when drying for a
smooth surface nish.
Field Assembly Procedures
Mixing the Burntech® mortar – The mortar comes premixed
a)
and should be dry. Be sure to use clean water and work it
up into a mixture that is pasty but not lumpy. If it’s too thin
and the surfaces don’t stay moist, the components will not
adhere. Load the mixture into a standard grout bag.
Apply about ½” (one-half inch) thread of mortar. The mortar
b)
bead should be approximately ½” (one-half inch) away from
all edges. The mortar has a considerable amount of holding
power so do not overload the components with too much
mortar. Keep the components moist at all times!
Tools needed for installations:
●
One 4’ level
●
Roto-hammer with ½” drill bit (needed for concrete slab
install only)
●
Drill motor with mixer blade (to mix Burntech® Mortar)
●
Two empty 5 gallon buckets (to mix Burntech® Mortar)
●
One wheelbarrow and shovel to mix concrete.
●
Grout bag
●
Triangular masonry trowel
●
Rubber hammer
●
Sponge and water bucket to wipe down and moisten parts
prior to applying mortar.
Materials needed for concrete slab installations
GBVS39:
Six (6) pieces 3/8” rebar x 36” long (included with unit)
Six (6) pieces of rebar x 12” long (included with unit)
GBVS44/49:
Eight (8) pieces 3/8” rebar x 36” long (included with unit)
Eight (8) pieces of rebar x 12” long (included with unit)
ALL UNITS:
●
Epoxy for securing rebar in footing / foundation.
●
Three (3) - 90 lb. bags of Ready-Mix Concrete with 1/4” or
smaller aggregate.
Some mortar will “ooze out” when placing components
c)
together, this is normal. Wipe excess away with a trowel. Do
not cover component surfaces completely with mortar. 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.
Make sure components are level. It’s extremely important
d)
that you pay careful attention to how you are assembling
the Burntech® Fireplace since every component builds on
the next. If you have to make any kind of an adjustment,
do not try to do it “by loading an opening” with mortar, this
will only result in a replace that will not be plumb or level.
Use wood shims instead. You will nd these small wood
shims supplied with the Burntech® Fireplace and
you can nudge them in between openings to achieve the
precision you need in making component adjustments.
Once you have removed any shims, you will want to cover
any gaps that may have resulted with the mortar.

Fireplace Assembly Procedures
Place the Burntech® replace hearth on the oor where the
1.
replace is to be installed. For concrete slabs, supporting
oor needs to be rated at ASTM 90.
Draw an outline of the hearth area based on the dimensions
2.
shown in Figure 12. Position Hearth slabs and mark rebar
center locations. Drill 4 inches into concrete slab and secure
the 8 pieces of 12 inch rebar with epoxy. For other than
concrete slabs, draw an outline of the hearth area based on
the dimensions in Figure 5 taking special consideration on
the position of where the all-thread studs will be located in
relation to the anchoring locations. All-thread rods should
stick up through the holes on the hearth slabs.

Burntech® Firebrick Liner
The rebrick lining is not supplied as part of your Burntech®
replace but can be purchased from Burntech®. They are
available in split herringbone and full running bond patterns.
(see Figures 24 and 25)
You also have the option to have custom rebrick installed,
but it must be at least 1-1/8” thick.
Before you install the lining, you will need to drill all the
required gas and electrical line feeds and the combustion air
supply access holes.
Disclaimer: Burntech® cannot be held liable for the way
firebrick or firebrick mortar performs. It is not unusual for heat
stress cracks to appear on the firebrick or firebrick mortar
during the life of the fireplace.

heat replaces, all Burntech® Fireplaces must comply with
building code safety clearances, per units that have
openings of 6 sq. ft. (six square feet) or greater. You must
keep combustibles such as trim 8” away from the rebox
opening (for mantel clearances, see Figure 26).

Attention: The manufacturer suggests that when building
out a replace, that the owner and installer opt for complete
safety. Burntech®, therefore, advises that combustible
mantel shelves feature clearances that are more than the
12” (twelve inch) minimum equal to the projection of the
shelf. As a guide, gure that a 10” (ten inch) wide shelf
should be 20” (twenty inches) above the replace opening.
Walls That Adjoin – Safety codes and all practical outlooks
2.
insist that your replace cannot be installed closer than 2 ft.
(two feet) to any walls in the room the replace is housed in
or to any walls of adjoining rooms.
13
Caution in Regards to Combustibles – If any part of the
3.
replace or objects in the room (curtains, rugs, paint,
cushions, etc.) start to show warping or discoloration due to
heat from the replace, it is time to take immediate action.
Each installation requires a different set of circumstances
to deal with the problem, but one thing is certain: do not
use the replace until you have gured out how to address
the problem. You are facing a potential re hazard. The
manufacturer of the Burntech® gas replace cannot be
responsible for the make-up of material on the exterior
of the replace you have chosen, nor can Burntech® be
held responsible for the materials in a room that may be
responding negatively to heat. However, in almost all
cases, there is a solution to the problem, either by making
adjustments to airow or the room itself.
Installing Outside Air
Note that the most important aspect of the installation is the
maintenance of minimum required clearances to combustible
materials. Those specic installation requirements must
be followed with great precision as you are dealing with the
potential of re hazard if the correct combustible limit is not met
and maintained. When you look at the drawings provided in this
section, you will see that actual installations may vary due to
individual design preferences. That is to be expected.
Design and framing specics may vary from the drawing
to installationy. Clearances to combustibles is a stringent
requirement.
WARNING:
If you do not use chimney manufacturer’s parts and/or if you
do not follow exact instructions for installation of chimney
components, you may be responsible for replace malfunction,
an accident or a re hazard.
Be mindful that outside, fresh air is not required for the
1.
operation of the Burntech® Fireplace. However, local
building codes may require combustion air and it is an
excellent choice in some situations, especially in weather
conditions where homes are very well insulated and
tightly sealed. Check local building codes for specic
requirements.
Install Outside Air Kit - BFP4-AK into the Burntech®
2.
Firebox either through the side wall opening provided. The
tubing that goes out of the rebox wall must feed into a
exible metal conduit as the source for outside combustible
air. It can go straight out through an outside wall or into a
ventilated crawl space. If crawl space is used, check codes
for proper termination.
Be sure that you carefully check the source of the outside
3.
air before you choose the site for your air intake. You don’t
want a place where snow will collect, where bushes or trees
will be growing or a location that is too close to any other
structure.
The suggested maximum height for the air intake tubing
4.
is 50 ft. (fty feet) above the hearth. That height is if the
intake nishes off at a minimum of 3 ft. (three feet) below
the chimney cap level.
Install a screened termination cap to keep out animals.
5.
Burntech® Chimney Systems
Overview
This Burntech® gas replace may be installed with an approved
10” B-vent chimney system. A metal chimney adapter is required
to attach the chimney to the top of the rebox. This can be
purchased from Burntech, part number TFS-DD.
Attention: Be advised that your choice of Chimney System
meets the following standards and requirements:
Designed for installation in accordance with National Fire
●
Protection Standard
Meets requirements of NFPA 211
●
Designed in accordance with BOCA Basic National Codes
●
Meets Uniform Building Codes.
●
General Chimney Requirements for Height and Clearance
When installed, the maximum overall height of the chimney
system from bottom of replace to the top/termination chimney
is 40 feet. The minimum installed height of the completed
Chimney System is 14 feet with a straight ue stack, 17 feet if
the chimney includes one or two offset sections.
Throughout the length of the chimney – along the outer
periphery of the ue you must have at least 1” (one inch) of
clearance all around the circumference. When the chimney is
passing through a living space, it must be completely closed off.
A “live” chimney is never allowed to be within reach of humans;
the chimney must be completely designed to be hidden from
view and protected, away from human interaction.
Note that it is acceptable for the chimney’s restop space and
roof ashing to come in direct contact with common construction
materials, such as drywall, ooring, paneling, plywood, millboard,
particle board and a variety of normal framing materials. Always
follow the specic installation requirements of your selected
chimney manufacturer.
Determining Finished Height for Fireplace
Installers are cautioned to put the chimney system together
exactly as instructed and shown in chimney manufacturer’s
guide. Any variations may have serious consequences resulting
in an accident or malfunction. If instructions are not followed,
the warranty on the product will become null and void.
Determine the number of chimney sections and the chimney
components that will be required for the installation. Bear
in mind that the minimum height of the Burntech® Fireplace
System once installed is 14’-0” (fourteen feet) and that it is
higher if offsets are used. Here is how to calculate the height of
the completed replace:
14
First, ascertain the height of the chimney. This includes the
1.
distance from the very top of the smoke dome to where the
top of the ue ends. That is where the smoke leaves the
ue.
Aside from the chimney sections, include all the components
2.
that you will be using in your installation - anchor plate
damper, restop spacers, stabilizers, and offsets.
Create a Component Height Chart by measuring each
3.
component and completing the following:
Anchor Plate = 4 ”
Firestop Spacers = _ _ _ _ _ _
Support box = _ _ _ _ _ _
Stabilizers = _ _ _ _ _ _
Offsets = _ _ _ _ _ _
Pipe Sections = _ _ _ _ _ _
(Stabilizer – Must be present on vertical chimneys every
30 feet and on offset chimneys every 10 feet.)
Take the total height of every component that will be included
4.
in your installation and then subtract that from the desired
total height you wish the nished replace system to be.
You will need to refer to the chimney manufacturer’s
5.
information in order to gure out the available lengths and
the quantity of the sections that you will need.
The Special Case of Offset Installation
Special instructions are given for proper handling of offsets for
the chimney system.
One elbow begins the installation procedure and the second
elbow is used to nish off each section. In all likelihood, a 30
degree offset elbow will probably be the rst hardware used off
the top of the anchor plate damper.
Note: Under no circumstances should you use an offset
elbow in place of a return elbow. They have distinct purposes
in the conguration of the offset installation and they cannot
be interchanged, part for part.
Depending on the conguration you are contending with,
2.
you may either attach the elbows and offset piping together
or you may need to insert sections of the vertical chimney.
Whatever the scenario, you cannot allow sections of the
chimney to measure more than 20’ (twenty feet) between
the elbows.
Assuming you have sections of vertical pipe that are more
3.
than 10’ (ten feet) measuring between elbows, you must
insert – at midpoint – a chimney stabilizer. When installing
the stabilizer, pull out the support straps with a good amount
of tension and hammer to the frame.
If your offset sections go over 6’ (six feet) in length, you
4.
will need to give added support using a sheet metal screw
– a # 8 x ½” is recommended. The screw will be fastened
underneath the joint.
To ensure a tight t for the screw, drill a hole that is 1/8”
5.
(one-eighth inch) in diameter right at the chimney joint’s
underside. Be sure that you position the drill at the very
center of where the joint overlaps. Be very careful not to
drill through the inner casting; drill only through the outer
chimney.
Maximum offset is 30 degrees off of vertical and there
•
should be no more than one offset sequence per chimney
system.
Under no circumstances should two offsets be attached to
•
comprise a 60 degree offset conguration.
Always maintain at least 2” (two inches) of clearance around
•
all offset installation for air space and necessary clearance
from combustibles.
Working with Floors and Ceilings
If your offset chimney installation passes through a oor or
ceiling, you will have to use a 30 degree angle offset in which
case you are advised to use a restop spacer.
Should the length of the chimney below the oor or ceiling be
less than 10’ (ten feet), support the chimney at the juncture of
the oor/ceiling with a stabilizer.
As in all phases of chimney component installation, you will
want to be sure you are making allowances at every juncture for
the 2” (two inch) clearance space from combustibles.
Background Information on Offset Installation
Installing Vent Plate and Chimney System
Before installing your B-Vent to the Burntech® Firebox you
must install a steel vent plate. The vent plate mudt be installed
in the vertical (open) position on the outside of the vent pipe
and is designed to close-off the chimney in the event the pipe
is removed or fails, thus alerting the operator of a problem.
Next, attach the masonry anchor plate (supplied). The
anchor plate is pre-drilled with holes for four (4) cement wedgeanchors.
Place the plate and mark the top of the rebox. Then remove
1.
the plate to carefully pre-drill holes for the wedge anchors.
Using the supplied vent plate, apply a 1/4” (one quarter
2.
inch) bead of gasket cement around the base damper lead
pipe. Apply ceramic rope gasket on to the gasket cement.
Apply balance of gasket cement in a 1/4” (one quarter
3.
inch) bead on top of smoke dome top approx. 3” (3 inches)
outside of outlet hole. Install damper on top of unit pressing
damper into cement. Attach using four (4) #8 cement
wedge-anchors.
When obstructions are present, it will be necessary to
1.
offset sections of the chimney using the 30 degree offset
component and, for every offset component, two elbow
components.
15
Venting Installation
A “B-type” venting system must be connected to the appliance
for venting to outside of building. The following section is
provided as a guide to a standard B-type vent installation.
Standing codes requirements concerning B-type vent
installations may vary within your state, province or local codes
jurisdiction. Therefore, it is recommended that you check with
your local building codes for specic requirements or in absence
of local codes, follow Section 7.0 of the current National Fuel
Gas Code ANSI Z223.1/NFPA 54 for Category I systems using
double wall B-1 vent pipe.
This gas appliance must be vented to the outdoors only
and may not be terminated into an attic space or into a chimney
ue servicing a solid fuel burning appliance.
This appliance may be vented through a manufactured
chimney system or a masonry chimney using a B-vent adapter
or a chimney liner system if the system is listed, inspected
and approved by local codes and/or building authorities. The
examples shown in Fig. 2 are typical of most B-vent installations
and codes practices.
Example 1: Shows the minimum allowable system height and
lateral offset for an inclination of 60° or greater.
Code species that offsets of 60° or greater are considered
horizontal and must follow the 75% rule for lateral to total vertical
system height.
Codes also allows only one offset in the total system when
at 60° or greater.
The total vertical height in this example represents the
minimum height of 8 ft. and therefore the allowable lateral is 6
ft. when the 75% rule applies.
If the lateral length must exceed 75% then the system must
be sized in accordance with the Category I venting tables.
Example 2: Shows a multiple offset each at a 45° inclination.
Multiple offsets are permitted if they do not exceed a 45°
inclination. The total lengths of the two offsets are not required
to meet the 75% allowable rule.
Example 3: Shows a single offset at 45° of inclination and
therefore the lateral length at 10 ft. of offset does not have to
meet the 75% rule.
In each case the offsets must be supported and restops
must be positioned wherever the vent must pass through a suboor, ceiling joist or an attic overhang.
The vent pipe must terminate vertically into a listed type
vent cap and extend a sufcient height through an approved
roof ashing, roof jack or a roof thimble. At all points the listed
clearances must be maintained.
Vent terminations must be located in accordance with
height and proximity rules of NFPA No. 54.
These rules apply to vents at 12” diameter or less and
require a minimum height in accordance with the roof pitch and
a minimum of 8 ft. distance from a vertical wall or obstruction
(see Fig. 3).
If venting horizontally through a side wall becomes
necessary, a listed thimble approved for use with B-type vent
must be used. Check with your local codes before venting
through a side wall.
Some codes areas allow the use of existing B-type vent
systems if the system is at or above the recommended diameter
of the ue.
The ue connection must be made using listed B-type
connectors and the existing system must be code inspected for
damage and proper installation.
It is not recommended that this appliance be common
vented with an existing gas burning appliance. However, if it
becomes necessary to common vent this appliance, the venting
system must be sized and congured in accordance with the
common venting guides Appendix G of the current National
Fuel Gas Code NFPA No. 54/ANSI Z223.1.
Note: Before connecting this appliance to an existing vent
system or a common venting system, consult with your local
architect, planner, or building ofcial.
Figure 2
16
Specifying Chimney Heights
If the horizontal distance from the mid-point of the chimney
to the peak of the roof ridge is less than 10 feet, the top of the
chimney must be at least 2 feet above the roof ridge. This is
called the “2 foot in 10 foot” rule.
If the horizontal distance from the chimney’s center
measured across to the ridge of the roof is more than 10 feet,
the top of the chimney still needs to be at least 2 feet above a
point measured from a distance of 10 feet horizontally along
the roof.
Figure 3
Chimney Termination Units
You will be installing at or possibly near the top of the
chimney chase ashing. A top termination unit is the essential
piece of equipment in keeping sparks out of the atmosphere.
Before installing this important piece of equipment, you will have
to make a judgment call as to whether or not the termination
unit – like all the other exterior exposed chimney components,
for that matter – should be painted in order to protect it/them
from rusting and weathering. Particularly if you are installing
the replace and chimney near water or in a high humidity area,
the manufacturer recommends a top quality, rust-proof paint
especially formulated for metal. Follow the paint manufacturer’s
directions, applying the paint well before you are scheduled to
install the round top termination unit or any of the ashings or
ues that will be exposed to outside weather conditions.
Venting terminals shall not be recessed into walls or siding.
This appliance, when installed, must be electrically grounded
in accordance with local codes and in the absence of local
codes, with the National Electrical Code, ANSI NFPA 70, or the
Canadian Electrical Code, CSA C22.1.
Important Pre-installation Information
Before you begin, review the information and safeguards
below regarding the installation and operation of the gas
Fireplace.
This replace may only be connected to the gas supply
listed on the label. Never use propane gas in a gas replace
designed for natural gas or natural gas in a gas replace
designed for use with propane gas.
Though there are many congurations in meeting these
requirements, chimney height cannot be less than 3 feet above
the roof at the edge of the chimney.
If the roof is at, the chimney must extend no less than 3
feet from where it intersects the roof. If the chimney is entering
the roof at an angle, measure the shorter angle where the
chimney intersects the roof which should be at least 3 feet.
Note: The previous guidelines do not take into consideration
outside conditions which may require a higher chimney due
to foliage, other buildings, power lines and weather conditions
in your area. Follow the chimney manufacturer’s installation
guide for further information.
*Nominal BTU based on gas inlet pressure. Nominal gas inlet
pressure for natural gas is 5” W.C.
The gas replace must be installed by an BURNTECH
Certied or other qualied professional installer. The installation,
including provisions for combustion and ventilation air, must
conform
with the latest edition of the National Fuel Gas Code, ANSI

completed, all elements of the replace and chimney system
must be completely dry. This means that the unit must stand
without any ring for a minimum of 28 days. Only after that
period of time can a rst lighting take place. Do not let the re
burn for more than one hour. After this rst lighting – when
the replace has started to “cure” Do not set another re for
at least 24 hours.
Second Lighting – With the second lighting you can let the
2.
re burn two hours – no more.
After First and Second Lighting – When the replace has
3.
been properly cured with careful “maiden” rings, you will be
able to run the burner for as long as you like.
Attaching the Burner and the Grate (Burntech Burner Only)
Unpack the burner assembly and place the rear legs of
1.
the burner into the brackets in the back of the rebox (see
Figure 23).
Thread the pilot lines from the burner pilot assembly and
2.
through the hole in the lower side of the rewall to the valve/
control box assembly and attach to the valve.
Connect the supplied ex connector from the output of the
3.
valve, through the hole and to the burner.
Connect the second ex connector from the input of the
4.
valve to the gas stub down stream from the required
manual shut-off valve.
Note: The required 1/8” NPT up stream pressure tap is built
into the valve (Figure 33).
CAUTION: CHECK ALL CONNECTIONS FOR GAS LEAKS
USING A HALF-AND-HALF SOAPY WATER SOLUTION.
IF A LEAK IS DETECTED TIGHTEN CONNECTIONS AND
TEST AGAIN.
NEVER USE AN OPEN FLAME TO CHECK FOR GAS
LEAKS.
Keep the fireplace area clear and free from combustible
materials, gasoline, and other flammable vapors and liquids.
Insert a one-way screw into the hole in the front of each
5.
bracket and tighten with a long (min. 12”) screw driver until
contact is made with the grate leg and the grate is permanently
locked in place (see Figure 23).
IMPORTANT: Once installed the burner cannot be
removed.
Fill in the holes you have drilled around the gas piping with
6.
the regular Burntech® mortar.
Checking and Adjusting the Pilot (Burntech burner only)
Follow the lighting instructions to light the pilot. The pilot
1.
ame should encircle the generator tip which is preset at the
factory (Figure 32). Ordinarily, the pilot will not require eld
adjustment.
If adjustment is necessary, remove the cap screw (Figure
2.
32) and turn the smaller gas adjustment screw inside
counterclockwise to increase the pilot ame and clockwise
to decrease the pilot ame. Replace cap screw.

Placing the Decorative Lava Rock
If desired, open the bag of lava rock and pour its contents around
the base of the grating in an attractive pattern. Do not place the
Lava Rock on the logs or grate.
Adjusting Air Mixers
Burners are equipped with air mixers for the top and front burners.
Adjust the size and color of the ame by opening (turn outward)
or closing (turn inward) as shown in Figure 33, 34.

Lighting and Operating Instructions (Burntech supplied burner only)
FOR YOUR SAFETY, READ BEFORE LIGHTING
WARNING: If you do not follow these instructions exactly, a re or explosion may result causing property
damage, personal injury or loss of life.
Do not use this gas replace if any part has been underwater. Immediately call for a qualied professional service technician to
inspect the replace and to replace any part of the control system and any gas control which has been under water.
The Burntech® burner system has a pilot which can be lit by hand using a match or lighter. When lighting the pilot, follow these
instructions exactly.
BEFORE LIGHTING, smell all around the burner area for gas. Be sure to smell next to the oor as some gas is heavier than air
and will settle on the oor. IF YOU SMELL GAS, FOLLOW THE INSTRUCTIONS ON THE COVER (P. 1).
TO LIGHT THE FIREPLACE WITH THE WALL
SWITCH
Move the ON-REMOTE-OFF wall switch to the ON position
(Figure 41). This transmits a rapid series of sparks at the pilot
head and will ignite the gas.
TO SHUT DOWN THE GAS FIREPLACE USING THE WALL
SWITCH
Move the switch to the OFF position (Figure 41). The gas ow
will cease, and all ames (main burner and pilot) will go out (see
important note below).
OPERATING THE BURNER USING THE REMOTE
Move the wall switch to the REMOTE position and follow the
instructions included in the remote kit for lighting and shutting
down the attached burner.
IMPORTANT: Do not allow the replace opening to be
blocked in any way while operating the replace. The
replace may be operated with a Burntech® screen installed
and drawn.
MAINTAINING THE PILOT
Your gas replace is equipped with a safety pilot that will shut
off the gas supply in case the pilot is not burning or functioning
properly. Regularly verify that the pilot is adjusted properly with
the pilot ame hitting the electrodes as shown in Figure 42. If the
pilot will not stay lit, call your local gas utility or gas supplier.
TO CHECK UPSTREAM GAS PRESSURE
Unscrew the four (4) screws above and below the control panel
face, then pull the control panel out far enough to expose the
test ports on the valve (Figure 41). Unscrew the port marked IN
part way and test.
CAUTION: Do not kink the ex connectors coming from the
valve while accessing it.

Maintenance and Service
Maintenance
Once installed and operating properly, the Burntech® gas
replace requires very little maintenance.
You should inspect the replace, chimney, burner and control
annually for the following:
Excessive Sooting - Some sooting of the logs is normal
1.
and adds to the natural appearance of burned wood. If soot
accumulates, you may brush the soot off with a stiff brush.
Logs may also be cleaned by allowing them to heat up, then
spraying them with water where soot has accumulated.
Debris around the control - Inspect the control and pilot to
2.
be sure it is free of any dirt or debris.
Insects and burner blockage - Check the burner ports
3.
and the air-mixer, if present, to make sure they are free
from debris. Blocked burner ports and orices may
result in poor ame distribution or ame at air mixer (if
equipped). Reference SOLUTION, to symptoms 2-4, of
