WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY A FIRE OR EXPLOSION
MAY RESULT, CAUSING PROPERTY DAMAGE, PERSONAL INJURY OF LOSS OF LIFE.
PILOT LIGHTING INSTRUCTIONS:
6
Figure 2. Lighting instruction label.
Operating Instructions
PILOT LIGHT:
1. Turn off the gas to the replace. If not recently done, remove the glass and let the unit air out
for at least ve (5) minutes to clear out any gas. Turn on gas to the heater. Leak test all joints
with soapy water. NEVER USE AN OPEN FLAME FOR LEAK TESTING.
2. Start the pilot by pressing the gas control knob and turning it to PILOT.
While holding the gas control knob in, press the piezo ignitor several
times until the pilot light starts. Hold the gas control knob in for thirty
(30) seconds. Check that the pilot has fully engulfed the thermocouple
assembly (see Figure 3).
3. Start the main burner by turning the gas control knob to ON and then turn
the rocker switch to ON. Check that all burner ports have ame.
4. Leak test all gas joints again.
Figure 3. Pilot ame.
VENTURI ADJUSTMENT:
The venturi adjustment lever is centered above the control panel.
The venturi allows the amount of air coming into the replace to be adjusted in order to accommodate
different climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot
ame is burning normally and none of the burner ports are plugged. Let the replace burn for roughly
fteen (15) minutes and then examine the ames.
The ideal ame will be blue at the base and
light orange above (see Figure 42). The ames
should be of medium height. If the ames look
like this, no venturi adjustment is needed. If
the ames are fairly short and mostly blue, the
replace is getting too much air. Therefore, the
air shutter should be closed (push in) slightly
until the correct ames are achieved. Flames
that are very orange, with tall dark stringy tips
are not getting enough air. Open (pull out) the
venturi until the ames clean up. If the venturi is
opened, then closed all the way, and the correct
ames cannot be attained, turn off the gas and
contact the dealer.
Figure 4. Venturi Adjustment Lever
Warning: Incorrect venturi adjustment may lead to improper combustion, which is a safety hazard.
Contact the dealer if there is any concern about the venturi adjustment.

Figure 5. Control Panel
FORCE IT. If the unit is going to be serviced, turn off the electrical power to the unit as well.
NOTE: When the unit is turned on for the rst time, it should be turned onto high, with the fan OFF, for
the rst four (4) hours. This will cure the paint, logs, gasket material, and other products used in the
manufacturing process. It is advised that a door or window be opened as the unit will start to smoke,
which can irritate some people. After the unit has gone through the rst burn, turn the unit OFF, including
the pilot, and let the unit get completely cold. Then remove the glass and clean it with a good gas
replace glass cleaner, available at your local Enviro dealer. See MAINTENANCE AND SERVICE - CLEANING THE
GLASS and MAINTENANCE AND SERVICE - GLASS DOOR REMOVAL.
REMOTE CONTROLS:
This replace can use an optional remote control or an optional cordless wall thermostat. If either of
these are to be used to control the replace for the majority of the time, leave the ON/OFF switch (on the
control panel) in the remote/thermostat position. Consult the instructions included with the remote/wall
thermostat for operation guidelines.
AIR DIVERTER CONTROL:
When the blower is on, the amount of air ow into the room can be adjusted
with the air diverter. When the lever is to the far left the room receives the
air, when the lever is to the far right the air goes out the duct and when
the lever in the middle the air goes to both the duct and the room. Lever is
found above the right end of the control panel, see Figure 6.
Figure 6. Air Diverter
BLOWER SPEED:
The blower will come on only when the replace is up to temperature (approximately
20 minutes). The speed of the fan can be changed by turning the fan control knob.
To turn the blower off, turn the knob COUNTER CLOCKWISE until it “clicks” off
(Figure 7).
It is advisable not to operate the blower below 1/3 speed as it puts a strain on the
windings of the blower and running the blower at lower speeds could also cause
premature fan failure.

Maintenance And Service
ROUTINE MAINTENANCE:
At least once a year, run through the following procedures to ensure the system is clean and working
properly. Check the burner to see if all the ports are clear and clean. Check the pilot to make sure it is not
blocked by anything. The pilot ame should be blue with little or no yellow on the tips.
Warning: Clearances must be sufcient to allow access for maintenance and service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts
specically approved with this appliance may result in property damage or personal injury.
The venting system must be periodically examined; it is recommended the examination is done by a
qualied agency.
CLEANING THE GLASS:
When the replace has cooled, remove the face of the replace along with the glass. See MAINTENANCE
AND SERVICE - GLASS DOOR REMOVAL. Check the gasket material on the back of the glass, making sure that
it is attached and intact.
During a cold start up, condensation will sometimes form on the glass. This is a normal condition with all
replaces. However, this condensation can allow dust and lint to cling to the glass surface. Initial paint
curing of the appliance can leave a slight lm behind the glass, a temporary problem. The glass will need
cleaning about two weeks after installation. Use a mild glass cleaner and a soft cloth; abrasive
cleaners will damage the glass and plated surfaces. Depending on the amount of use, the glass
should require cleaning no more than two or three times a season. Do not clean the glass when it is
hot.
CLEANING THE FIREBOX:
Remove the logs carefully, as they are very fragile. Gently remove all the embers and rock wool and place
on a paper towel. Vacuum the bottom of the rebox thoroughly. Carefully clean any dust off the logs and
remove any lint from the burner and pilot. At this time, inspect the burner pan for cracking or severe
warping. If a problem is suspected, contact the dealer. Check the logs for deterioration or large amounts
of soot; a small amount on the bottom side of the logs is normal. Replace the logs and embers as in the
LOG SET AND EMBER INSTALLATION section. If new/more embers and rock wool are required, contact your
nearest ENVIRO dealer.
REPLACING GLASS:
The glass in the replace is a high temperature ceramic. If the glass is damaged in any way, a factory
replacement is required (see PARTS LIST - COMPONENTS). Wear gloves when handling damaged glass door
assembly to prevent personal injury. When the glass door assembly is being transported, it must be
wrapped in newsprint and tape and/or a strong plastic bag. Do not operate with the glass front removed,
cracked or broken. Removal and replacement of the glass from the door must be done by a licensed or
qualied service person. The glass must be purchased from an ENVIRO dealer. No substitute
materials are allowed.

Maintenance And Service
glass
CLEANING DECORATIVE SURFACES:
Painted and porcelain faces should be wiped with a damp cloth periodically. If a plated face has been
purchased, it should be unpacked/unwrapped carefully to avoid getting anything on the surface of the
nish, including cleaners, polish and nger prints. It is important to note that ngerprints and other
marks can leave a permanent stain on plated nishes. To avoid this, give the face a quick wipe with
denatured alcohol on a soft cloth BEFORE lighting the replace. Never clean the face when it is
hot. Do not use other cleaners as they may leave a residue, which can become permanently etched into
the surface.
If your ngers come into contact with the antique copper nish, the oils left as ngerprints on the copper
can cause discoloration, which will eventually turn green in that area. You can clean the patina or discolored
areas of the antique copper nish with “OO” 3M green sanding pads. These can be purchased from most
hardware stores. On the areas with discoloration, use the sanding pads to sand in the same direction as
the brushed nish, then blend the nish by feathering in the surrounding area. This renishing procedure
has been approved by the manufacturer and will not harm the nish. Please note: ANTIQUE COPPER IS
THE ONLY FINISH THAT CAN BE SANDED, DO NOT SAND PEWTER, GOLD OR NICKEL FINISHES.
GLASS DOOR REMOVAL:
In order to install the log set, and for regular
cleaning, the glass door will need to be
removed. With the face off, there are two
(2) handles on either side of the glass. They
rotate 90° until parallel with the oor (see
Figure 8). The top of the glass will move
away from the rebox and then the glass
door can be lifted off the resting points.
To replace the glass door, simply reverse the
above procedure.
Warning: Do not touch or attempt to
remove the glass if the replace is not
completely cold.
WARNING: Never operate the replace
with the glass removed.

CORNER INSTALLATION:
The dimensions for installing a replace in the corner of a room are given below in Figure 11.
Figure 11. Dimensions for a corner installation.
RAISED FIREPLACES AND HEARTHS:
There are a few options with raised replaces: raised with no hearth, raised with a raised hearth, or raised
with a oor level hearth. If the replace is 4 inches (101 mm) or more above the oor, a hearth is not
required. This measurement should be taken from the top of the ooring, i.e. the top of the carpet. The
replace cannot be placed within 37 inches (940 mm) of the ceiling. When installing a raised replace, it
is imperative that the support stand is strong enough to hold the weight of the replace and venting.

If the unit is raised 4” (102mm) or less it is mandatory to have a hearth installed with a protector pad
(sheet metal) placed directly on the oor or hearth framing, with the cement board (see specs below) on
top of it. Tile, or another non-combustible material forms the top layer of the hearth. A decorative trim
may be added to the edge of the hearth. The trim can be
combustible as long as the hearth extends at least 16”
(406 mm) in front of the replace and 1” (25 mm) on
either side of the replace opening (see Figure 15). To
install the face, it is necessary for the bottom ange of the
replace opening to overlap or be ush with the tile. If the
total thickness of the protector pad, cement board, and
nished tile is more than 1” (38 mm) the replace must
be raised to accommodate additional thickness.
Figure 14. Raised Fireplace with Raised Hearth
FIREPLACE SURROUND:
NOTE: Any paint that is applied to the mantel or facing above the unit should be “heat resistance” or it
may discolour.
CEMENT BOARD: The cement board can
be fastened to the front of the unit with selfdrilling metal screws. It is safe to screw to the
outer border of the replace. Cement board for
the hearth can be purchased at a local building
material store. The board must have a k-value
of 7.69 Btu/(ft² × h × °F) [13 W/m × K] and a
R-value of 0.13 ft² × h × °F/Btu [0.023 m² ×
K/W] or better.
TILED FINISH: Because of the amount of
heat exuded by the replace, drywall cannot
come directly up to the replace. Figure
15 shows the minimum dimensions for the
cement board. Tile or other non-combustible
materials cover the cement board, but do not
overlap into the replace opening. The total
depth of the cement board and the nishing
materials should be a minimum of 1” (25 mm)
to maximum of 1” (35 mm). The replace
front will be installed over top of the nishing
material.
SMOOTH FINISH: The replace will have to
be recessed by ” (12 mm) and two (2) layers
of cement board must be used if the area
around the replace will be nished ush with the rest of the wall.
ROCK OR BRICK FINISH: If the face of the replace is to be recessed, the face option chosen will
determine the size and shape of the surrounding material (i.e. brickwork). Since the dimensions provided
on the face option instruction sheet are only approximations, it is recommended that the steel template
of the chosen face is used. See PARTS LIST - OPTIONS for the face template part number.

VENTING:
This replace has been tested and certied for use with SIMPSON DURAVENT DIRECT VENT TYPE “GS”
PIPE FOR GAS STOVES, SECURITY CHIMNEY’S SECURE VENT DIRECT VENT SYSTEM kits, and MDV
SELKIRK METALBESTOS.
A 1” (25 mm) clearance to combustibles must be maintained
around any vertical vent pipe. Around a horizontal vent
pipe, the clearance to combustibles should be 2” (51 mm)
above and 1” (38 mm) on the sides and bottom. When
combustible materials are directly above a 90° elbow, 5” (127
mm) of clearance are necessary. See Figure 18
A 10” (254 mm) x 10” (254 mm) frame (see Figure 19) will
assure the proper support and spacing for the vent pipe as it
passes through the wall. Installations in Canada require that
a wall thimble be used for passing through walls and ceilings.
All sealing and vapour barriers must comply with local building
codes.
When planning an installation, it is necessary to select the
proper length of vent pipe for the particular requirements. The
conguration of the venting pipes depends on the locations
of walls, ceilings and studs. However, the pipes cannot be
of arbitrary length and arrangement. Because the length of
the vertical and horizontal sections dramatically affects the
burning efciency of the replace, certain guidelines have
been set in INITIAL INSTALLATION - VENT CONFIGURATIONS AND
RESTRICTOR SETTINGS.
Venting terminals can not be recessed into
a wall or siding.
WARNING: This gas appliance must
not be connected to a chimney ue
serving a separate solid-burning
appliances.

VENT CONFIGURATIONS AND RESTRICTOR SETTINGS:
Figures 20 shows the range of venting options, it shows possible vent congurations if the unit is top
vented, for vertical and horizontal terminations, any layout that remains within the shaded area is
acceptable. Having the fewest number of elbows is ideal, as they tend to disrupt air movement. Using
45˚ elbows is preferable to using 90˚ elbows. Also, a shorter vent system will perform better than a
longer one.
The vent restrictor controls the amount of air
moving through the vent pipe. Longer vertical
vent lengths necessitate greater restriction;
position 1 is open and position 5 is maximum
restriction. Figure 20 shows the vent restrictor
settings required, relative to the length of vent
pipe. The vent restrictor is located on the right
side of the replace, above the glass. Figure
21 shows the vent restrictor handle and the
holes that indicate the different levels. To avoid
injury, it is best to make this adjustment when
the replace is cool or use welder’s gloves or
oven mitts.
Note: 0,0 in Figure 20 represents a 90˚ bend
directly off the outlet of the unit, 46” (1169 mm)
from oor. This is for all horizontal instances
except when using Selkirk and having less
than a 4 feet (1.22 m) rise and 8 feet (2.44 m)
horizontal offset. In this case, a 1 foot rise must
be added below the 90˚ bend.

HORIZONTAL TERMINATION:
NOTES:
1. Horizontal pipes must not be level. For every 12 inches (305 mm) of horizontal travel
(away from the stove), there should be at least inch (6.4 mm) of vertical travel. Never
allow the vent to run downward, as this could cause high temperatures or even present
the possibility of a re.
2. The exterior of the horizontal
vent termination must not be
blocked or obstructed.
3. If the vent termination is not
being attached to wood, the
four wood screws provided
should be replaced with
material appropriate fasteners.
4. For buildings with vinyl siding,
a vinyl standoff should be
installed between the vent cap
and the exterior wall. Attach
the vinyl siding standoff to
the horizontal termination.
Note that the termination
bolts onto the at portion of
the standoff, providing an air
space between the wall and
the vent termination. The air
gap prevents excessive heat
from possibly melting the vinyl
siding.
5. Horizontal pipes must be
supported every 3 feet (914
Figure 22. Horizontal Vent Termination
mm). Plumber’s all round strap will sufce.
6. When running horizontal pipe, clearances to combustibles must be maintained 1 inches (38 mm)
sides, 1 inches (38 mm) bottom, and 2 inches (51 mm) top.
Step 1. Set the replace in the desired location. Check to determine if wall studs will be in the way when
the venting system is attached. If this is the case, the location of the replace may have to be
adjusted or the venting may have to be offset.
Step 2. Direct vent pipe sections are designed with special twist-lock connections. Dry t the desired
combination of pipe and elbows to the appliance adaptor.
Step 3. With the pipe in the correct position and attached to the replace, mark the wall for a 10 inches
(25.4 cm) x 10 inches (25.4 cm) square hole (see Figure 19). The center of the hole should
match the center line of the horizontal pipe. Cut and frame the hole in the exterior wall where
the vent will be terminated. If the wall being penetrated is made of a non-combustible material
(i.e. masonry or concrete) a 7 inches (17.8 cm) hole is acceptable.

NOTE: For Simpson Duravent only, place a bead of Mil-Pac or Rutland No 78 Stove and Gasket Cement
on the outer edge of the inner exhaust pipe (non-ared end). Push the pipe sections together, then twist
about turn, making sure the two sections are fully locked. Wrap all seams with foil ducting tape.
Step 4. With the hole now framed, the wall thimble installed, and the pipe extending into the wall,
proceed to the outside. Attach the termination to the pipe using RTV and Mil-Pac or Rutland No
78 Stove and Gasket Cement to seal joints. The vent pipe must extend into the vent cap at least
1 inches (3.2 cm). Secure the connection between the vent cap and the pipe by attaching the
two (2) sheet metal straps, which extend from the vent cap assembly to the outer wall of the
vent pipe. Bend any remaining portion of the strap back towards the vent cap. Security Secure
Vent uses a twist lock cap.
Step 5. Position the horizontal vent termination in the center of the 10 inches (25.4 cm) square hole
and attach to the exterior wall with the four screws provided. The arrow on the vent termination
should be pointing up. Run a bead of non-hardening mastic around the edges of the vent
cap, to make a seal with the wall. Ensure the proper clearances to combustibles have been
maintained.
VERTICAL TERMINATION:
Step 1. Check the instructions for required clearances (air spaces) to combustibles when passing
through ceilings, walls, roofs, enclosures, attic rafters, or other nearby combustible surfaces.
Do not pack air spaces with insulation.
Step 2. Set the gas appliance in the desired location. Drop a plumb bob down from the ceiling to
the position of the appliance ue exit, and mark the location where the vent will penetrate
the ceiling. Drill a small hole at this point. Next, drop a plumb bob from the roof to the hole
previously drilled in the ceiling, mark the spot where the vent will penetrate the roof. Determine
if ceiling joists, roof rafters, or other framing will obstruct the venting system. You may wish to
relocate the appliance, or to offset, to avoid cutting load bearing members.
Step 3. To install the Round
Support Box/Wall Thimble
in a at ceiling, cut a 10
inch (25.4 cm) square hole
in the ceiling, centered in
the hole drilled in Step 2.
Frame the hole as shown
in Figure 19.
Step 4. Assemble the desired
lengths of black pipe
and elbows necessary to
reach from the appliance
adapter up through the
Round Support Box.
Insure that all pipe and
elbow connections are
in their fully twist-locked
position.

STEP 5. Cut hole in the roof centered on the small hole placed in the roof from Step 2. The hole should
be of sufcient size to meet minimum requirements for Clearance to Combustibles, as specied.
Continue to assemble lengths of pipe and elbows necessary to reach from the ceiling support
box up through the roof line. Galvanized pipe and elbows may be utilized in the attic, as well
as above the roof line. The galvanized nish is desirable above the roof line, due to the higher
corrosion resistance.
STEP 6. Once the pipe sections have been joined, and run up through the hole in the roof, slip an elbow
strap over the exposed sections, bend the support straps outwards, and push the elbow strap
down to the roof level, as shown in Figure 23. Tighten the clamp around the pipe section. Use
a level to make sure the pipe is truly vertical. With roong nails, secure the support straps to
the roof. Seal the nails holes heads with non-hardening mastic. Trim the excess length of the
support straps that extend out beyond the edge of the ashing.
STEP 7. Slip the ashing over the pipe section protruding through the roof. Secure the base of the
ashing to the roof with roong nails. Use a non-hardening sealant between the uphill edge
of the ashing and the roof. Insure the roong material overlaps the top edge of the ashing.
Verify that you have at least the minimum clearance to combustibles at the roof line.
STEP 8. Continue to add pipe sections until the height of the vent cap meets the minimum code
requirements. Refer to Figure 24 and Table 3. Note that for steep roof pitches, the vent height
must be increased. In high wind conditions, nearby trees, adjoining roof lines, steep pitched
roofs, and other similar factors can result in poor draft, or down drafting. In these cases,
increasing the vent height may solve the problem.
STEP 9. Slip the storm collar over the pipe, and push it down to the top of the roof ashing as shown
in Figure 23. Use the non-hardening sealant around the joint between the pipe and the storm
collar.
STEP 10. Twist-lock the vent cap.

NOTES:
(1) If an offset is necessary in the attic to avoid
obstructions, it is important to support the vent
pipe every 3 feet (914 mm), to avoid excessive
stress on the elbows, and possible separation. Wall
straps are available for this purpose (see Figure
25).
(2) When ever possible, use 45° degree elbows instead
of 90° degree elbows. The 45° degree elbow offers
less restriction to the ow of ue gases and intake
air.
(3) For multi story installations; a ceiling restop is
required at the second oor, and any subsequent
oors (see Figure 26). The opening should be
framed to 10” (254 mm) x 10” (254 mm) inside
dimensions, in the same manner as shown in
Figure 19.
Figure 25: Use of Wall Straps.
(4) Any occupied areas above the rst oor,
including closets and storage spaces,
which the vertical vent passes through,
must be enclosed. The enclosure may be
framed and sheet-rocked with standard
building materials. However consult
the appliance manufactures installation
instructions for the minimum allowable
clearance between the outside of the vent
pipe, and the combustible surfaces of
the enclosure. Do not ll any required air
spaces with insulation.

DUCTING:
The option of ducting allows heat from the replace to be transferred to a different area. The maximum
total length for the ducting is 20 feet (6.1 m). There are four (4) duct outlets that can be used (see Figure
27), however, the blower puts out 200 cfm no matter how many ducts are used. Therefore, the more
ducts there are, the less air goes through each one. A short, straight duct maximizes its heating ability
as air in the ducts is restricted by the length and number of bends in the pipe.
For the rst 24 inches (610 mm) of
ducting, inch (13 mm) of clearance
is required. After 24 inches (610 mm),
the duct can be run with 0 inch (0 mm)
clearance, though inch (13 mm) is
preferred. To avoid heat loss, insulate
the duct whenever it passes through an
unheated area (i.e. crawl space). Insulating
the ducts elsewhere helps the efciency of
the ducting system.
Standard galvanized ducting and heat
registers are to be used. Simply remove
the desired cover plate from the outside of
the rebox and attach a 6 inches (152 mm)
starter ring. Make sure to foil-tape all seams
to prevent leaking. Ensure all ducting meets
local building codes.

during any pressure testing where the pressure
exceeds PSIG (3.45 KPa) or damage will occur
to the valve.
The appliance must be isolated from the gas supply
piping system by closing its individual manual
shutoff valve during any pressure testing of the gas
supply piping system at test pressures equal to or
less than psig (3.45 KPa).
Always check for gas leaks with a soap
and water solution after completing the
required pressure test.
TO TEST VALVE PRESSURES
The pressure taps are located on the left side of the valve
• Turn set screw 1 turn counter clockwise to loosen,
• Place 5/16” (8 mm) I.D. hose over pressure tap system.
• Check pressures using a manometer.
• When nished, release pressure, remove hose & tighten set screw.

CERAMIC BRICK LINER REMOVAL:
WARNING: DO NOT INSTALL LINER IF UNIT IS HOT.
1. Remove glass door (see MAINTENANCE AND SERVICE - GLASS DOOR REMOVAL)
2. Carefully remove the log set if it was installed.
3. Remove both side brick liners by sliding them out the front. Be careful not to scrape the liners on the
bafe tabs at the top.
4. Hold the back of the top liner up while lifting the back liner off the air deector ledge then out. Slide
the top liner out from the lip on the bafe then remove it from the unit.
5. If the bafe needs to be removed use a T-20
screwdriver to loosen off but not remove the
two (2) screws at the back of the bafe and
remove the two (2) screws at the front of the
bafe. Slide the bafe up over the back screws
then out.
To install the liners follow steps 1 to 5 in reverse.
Important installation notes:
Ensuring the side brick liners are behind the bafe
tabs and are ush against the rebox walls.
When sliding the bafe into place making sure
to hook the back into place on the two loosened
screws.
To install the log set follow the instruction in LOG
SET AND EMBER INSTALLATION.
Figure 33: Cast Iron Brick Liner Installation.
LOG SET AND EMBER INSTALLATION:
The placement of the logs is not arbitrary. If they are positioned incorrectly, the ames can be “pinched”
and will not burn correctly. The burner (Figure 34) and a few of the logs come with locator pins, notches,
and ledges which make alignment easier. The andirons and grate must be installed for the logs to be
placed properly. Using the pictures provided, carefully set the logs in place (see Figures 35 through 41).
NOTE: The logs are fragile and should be handled gently.
Maintenance: Once a year the logs should be removed and checked for deterioration or large amounts
of soot. A small amount on the bottom side of the
logs is normal. Remove and replace the logs in the
same manner described in this section.
If new/more embers and rock wool is required,
contact your nearest ENVIRO dealer.
Never operate the replace with the glass
door removed.

Figure 35: The rst log to be placed
is the front right log. The back
end has a hole that sits on the right
burner pin (see Figure 34) and the
front has a notch that helps it rest on
the center of the grate against one of
the vertical bars. Second to be placed
is the bottom log. The bottom log
rests on the center and right ledge in
the rebox (see Figure 34) and the
large end must be at against the
right brick liner.
Figure 36. Second Stage Log Set Installation
Figure 36: The back left log rests
on the left ledge in the rebox (see
Figure 34) and the left ledge on the
bottom log (see Figure 35). The large
end must be at against the left brick
liner.
Figure 37: The top of the far left
log has a hole that rests on the pin
and ledge of the back left log (see
Figure 36). The bottom of the far left
log rests against the base of the left
andiron. The top of the far right
log has a hole that rests on the right
pin and ledge of the bottom log (see
Figure 35) and the bottom of the far
right log rests against the base of the
right andiron.

Secondary Installation
Figure 41: Once the logs are in place the embers can be placed onto and around the burner to create
a realistic look. Bags of ceramic ber embers and rock wool are provided. The ceramic ber comes in
chunks that are about 2” (51 mm) long. Place them irregularly around the burner. When there is a
sparse but even layer of embers, spread the rock wool in the same manner. DO NOT pack this ember
material as this could create an
unsafe condition. The pieces
should be lightly placed so they
don’t completely block any of
the small burner ports. DO NOT
allow any of the embers to rest
against the pilot assembly.
Caution: Use only the type of
ember material supplied with this
replace. Due to the irregular
size of the ember material, there
may be more than required. Use
of other foreign materials on the
burners may create dangerous
conditions.

NOTE: While the glass is still
removed, it is recommended
that the gas line be purged
by lighting the pilot.
When lighting the replace
for the rst time since the
log set and embers have
been installed/replaced,
watch for ignition at ALL
the burner ports. If a long
delay is noticed, turn the
appliance off and wait for it
to cool down. Then remove
the glass and rearrange the
ember material, making
sure none of the burner
ports are blocked.
