Operating Instructions
For Your Safety, Read Safety Precautions And
Lighting Instructions Before Operating
WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY A FIRE OR EXPLOSION MAY
RESULT, CAUSING PROPERTY DAMAGE, PERSONAL INJURY OF LOSS OF LIFE.
A) Make sure the pilot is lit.
B) Turn gas control knob COUNTER CLOCKWISE to ON.
C) Flip the burner switch to ON.
D) Turn HI/LO knob to the desired ame height.
E) Turn on all electrical power to the unit.
NOTE: Check that all burner holes are lit.
TO TURN GAS FIREPLACE OFF
Flip switch to OFF to turn off burners only.
If the replace is to be turned off for the season, or for
servicing, turn the gas shut off valve to OFF. DO NOT
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 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 Envirogas dealer.
See page 23 for glass removal and page 8 for glass cleaning information.
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.
When the blower is on, the amount of air ow into the room can be ajusted
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 gure 4.
BLOWER SPEED:
The blower will come on only when the replace is up to temperature (approx 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 5).
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.
CLEANING THE GLASS:
When the replace is cool, remove the face of the replace along with the glass. See Secondary Installation.
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. Replace the logs and ember as in Secondary Installation.
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). 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 qualied service person. The glass must be purchased from an
ENVIRO dealer. No substitute materials are allowed.
CLEANING THE FACE:
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 unless it is cool. 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 renishing 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.
Warning: Clearances must be sufcient to allow access for maintenance and service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts specically
approved with this appliance may result in property damage or personal injury.

Initial Installation
QUALIFIED INSTALLERS ONLY
INTRODUCTION:
This section of the owner’s manual is for the use of qualied technicians only. Fireplace placement, hearths, facings,
mantles, and venting terminations will be covered, as well as the gas and electric systems. There are several
installation safety guidelines that must be adhered to. Please carefully read the safety precautions at the front of
this manual.
PLACEMENT:
The location for the replace can be along a wall, raised or at oor level, or in a corner. There are specic framing
measurements for each situation. The basic opening should have the dimensions shown below in Figure 6.
The replace must have a strong and level surface to be placed on. The surface should be made of wood or a non-
combustible material, not carpet.
The 19 7/16in (49.4cm) dimension takes into account the 1in (2.5cm) standoff on the back of the rebox. The
framing boards may touch the standoffs, but no insulating material can be placed between the frame and
the standoffs.
The gas line, 3/8in MPT, should be brought to the right side of the replace. If this set up is inconvenient, the
electrical wire and the gas line conguration can be reversed.
The location should be chosen so the replace will be at least 36in from drapes, doors and other combustibles. The
replace opening should also be at least 5in from the nearest perpendicular wall.

QUALIFIED INSTALLERS ONLY
CORNER INSTALLATION:
The dimensions for installing a replace in the corner of a room are given below in Fig 7.
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 3in (7.6cm) 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 41in
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.

FIREPLACE SURROUND:
If a hearth is to be installed, the protector pad (sheet metal) is placed directly on the oor or hearth framing, with
the cement board 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 12in (30cm) in front of the replace and 1in (2.5cm) on either side of the replace opening. 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” (2.5cm) the replace must
be raised to accommodate additional thickness. 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. NOTE: The Manor (the cast iron) face does NOT require any oor
protection even when installed at oor level.
board and the nishing materials should be a minimum
of 1in (2.5cm) to maximum of 1 in (3.5cm). The
replace front will be installed over top of the nishing
material.
SMOOTH FINISH: The replace will have to be
recessed by in (1.3cm) and 2 layer 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 recommened that the steel
template of the chosen face is used. See Parts List for
the face template part number.

NOTE: Any paint that is applied to the mantel or facing above the unit should be “heat resistance” or it may discolour.
TILED FINISH: Because of the amount of heat exuded by the replace, drywall cannot come directly up to
the replace. Figure 12 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

VENTING:
This replace has been tested and certied 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 1in (2.5cm) clearance to combustibles must be maintained around any vertical vent pipe. Around a horizontal
vent pipe, the clearance to combustibles should be 2in (5cm) above and 1 1/2in (3.75cm) on the sides and bottom.
When combustible materials are directly above a 90° elbow, 4in (10cm) of clearance are necessary. A 10in (25cm)
x 10in (25cm) frame 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. See Figure 17. 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 conguration 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 efciency of the replace, certain guidelines have been set.
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:
Fig 18 shows the range of venting options. Any layout that remains within the shaded area of Figure 18 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 necessitiate
greater restraint. Figure 18 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 18 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.

HORIZONTAL TERMINATION:
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
adapter.
Step 3. With the pipe in the correct position and attached
to the replace, mark the wall for a 10in x 10in
square hole. 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 7in hole is acceptable.
NOTE: For Simpson Duravent only, place a bead of Mil-Pac
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.
This method makes disassembly easy and reassembly can be done the way it was origianally assembled.
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 MilPac to seal joints. The vent pipe must extend
into the vent cap at least 1”. Secure the connection between the vent cap and the pipe by attaching the
two sheet metal straps, which extend from the vent cap assembly to the outerwall of the vent pipe. Bend
any remaining portion of the strap back towards the vent cap.
Step 5. Run a bead of non-hardening mastic around the edges of the vent cap, to make a seal with the wall.
Position the horizontal vent termination in the center of the 10in square hole and attach to the exterior wall
with the four screws provided. The arrow on the vent termination should be pointing up. Ensure the proper
clearances to combustibles have been maintained (see page 14).
See page 18 for important notes.

attic rafters. See end of this section. Do not pack air
spaces with insulation.
Step 2. Set the replace in the desired location. Drop a plumb
bob down from the ceiling to the ue exit. Mark the
location where the vent will penetrate the ceiling and
drill a small hole at this point. Next, drop a plumb
bob from the roof to the hole drilled in the ceiling.
Mark the spot where the vent will pass through the
roof. Determine if the ceiling joists, rafters or other
framing members will obstruct the venting system.
The replace may need to be relocated to avoid
cutting any load bearing members or an offset elbow
can be used.
Step 3. To install the wall thimble in a at ceiling, cut a 10in
(25.4cm) x 10in (25.4cm) x 10in square hole in the
ceiling. The previously drilled hole should be at the
center of the new hole. The square hole should be
framed. See Figure 17.
Step 4. Assemble the desired lengths of pipe and elbows
necessary to reach through the square hole from
the replace adapter. Ensure all the pipe and elbow
connections are fully twisted and locked together.
Step 5. Cut a 10in (25.4cm) x 10in (25.4cm) hole in the roof,
centered on the small hole cut previously. Continue to
assemble lengths of pipe necessary to reach from the
ceiling support box up through the roof line.
NOTES:
1. Horizontal pipes must not be level. For every 12in (30cm) of horizontal travel (away from the stove),
there should be at least 1/4in (6mm) 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 3ft. Plumber’s all round strap will sufce.
6. When running horizontal pipe, clearances to combustibles must be maintained (1in (3.8cm) sides, 1” (3.8cm)
bottom, and 2” (5.1cm) top)

Step 1. Check required clearances to combustibles when passing through ceilings, walls, roofs, enclosures, or

Step 6. Once the pipe sections have been joined and run up through the roof, slip a pipe support strap over the
exposed sections. Bend the support straps outwards and push the pipe support strap down to the roof level.
Use a level to make sure the pipe is vertical and tighten the clamp around the pipe section. With roong
nails, secure the support straps to the roof and seal the nail heads with non-hardening mastic. Trim the
excess length of the straps. If the installation is taking place in a nished house the pipe support straps can
be attached to the rafters in the attic. See gures 21 and 22.
Step 7. Slip the ashing over the pipe section protruding from the roof and secure the base of the ashing with
roong nails. Use a non-hardening sealant on the nail holes and the edges of the ashing. On a sloped
roof, make sure the shingles overlap the top edge of the ashing.
Step 8. Continue to add pipe sections until the height of the vent cap meets the minimum code requirements (see
Table 1). In high winds, nearby trees, adjoining roof lines, steep roof pitches, 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 ashing. Use the non-hardening
sealant around the joint between the pipe and the storm collar.
Step 10. Twist on the vent cap until it locks.

NOTES:
1. If an offset is necessary to avoid obstructions in the attic,
the vent pipe must be supported every 3ft (91.4cm) (see gure
22).
2. Whenever possible, use two 45° elbows rather than two
90° elbows, as the 90° elbows tend to restrict the ow of ue
gases.
3. For multi-story installations, a ceiling re stop is required
at the second oor and any subsequent oors. The opening
should be a framed 10in (25.4cm) x 10in (25.4cm) hole.
4. Any areas above the rst oor, including closets and storage
spaces which the vent passes through, must be enclosed.
The enclosure can be framed and sheet rocked with standard
building materials. All minimum clearances must be maintained.
Do not ll any of the 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 20ft (6.1m). There are four duct outlets that can be used, however, the blower puts out 200cfm
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 24in (61cm) of ducting, 1/2in (1.3cm) of clearance is required. After 24in (61cm), the duct
can be run with 0in clearance, though 1/2in (1.3cm) 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 efciency 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 6in (15.2cm) starter ring. Make sure to foil-
tape all seams to prevent leaking. Ensure all ducting meets local
building codes.
