Operating Instructions
For Your Safety, Read Safety Precautions And Lighting Instructions Before Operating.

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.
NEVER USE AN OPEN FLAME FOR LEAK TESTING
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 5.
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.
Thermopile Thermocouple
Figure 3. Pilot ame.
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.
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 49). 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.

Operating Instructions
buRneR Lighting:
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 (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.
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.
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.

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 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.
The venting system must be periodically examined; it is recommended the examination is done by a
qualied 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 the door assembly
with the damaged glass 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.

Maintenance And Service
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 discoloured 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.
gLass DooR RemovaL:
glass
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

QUALIFIED INSTALLERS ONLY
intRoDuction:
This section of the owner’s manual is for the use of qualied technicians only. Fireplace placement,
hearths, facings, mantels, 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 15.
Warning: Clearances must be sufcient
to allow access for maintenance and
service.
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 19½ inches (494 mm) dimension
takes into account the 1 inch (25 mm)
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, 3/8” NPT, 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 36 inches (914
mm) from drapes, doors and other
combustibles. The replace opening
should also be at least 5 inches (127
mm) from the nearest perpendicular wall
(sidewall to the edge of the opening).

coRneR instaLLation:
The dimensions for installing a replace in the corner of a room are given below in Figure 11.
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 3 inches (76 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 41 inches (1041 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.

trim can be combustible as long as the hearth extends at least 12” (305 mm) in front of the replace
and 1” (25 mm) 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” (25 mm) the replace must be raised to
accommodate additional thickness. NOTE: The Manor (the cast iron) face does NOT require any
oor protection even when installed at oor level.
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 self-drilling 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 (metric version: 13
W/m × K) and a R-value of 0.13 (metric version: 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 21 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 1⅜” (35 cm). The replace front will be installed over top of the nishing material.
SMOOTH FINISH: The replace will have to be
recessed by ½” (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.

sealant to the new Ø4” (10 cm) by
5” (12.5 cm) provided ue collar
adaptor. Press the ue collar into
the ue outlet of the replace so
that the Mill-Pac seals the ue
collar to the ue outlet.
7. Stretch both the Ø4” (10 cm) ex
vent and the Ø6⅝” (16.25 cm) ex
intake liner to the length needed
to ensure the ex can be easily
connected to the vent terminal.
8. Slide the Ø6⅝” (16.25 cm) ex
intake liner over the ex vent.
Install four (4) wire spacers
around the ex pipe. Ensure the
wire spacers are positioned at
either end of the pipes, and at
each end of any elbows in the
liners (refer to Figure 25 and 26).

9. Install the ex pipe assembly through the wall thimble, ensure that this portion of pipe slides through
the outside wall far enough to connect onto the vent termination cap.
10. Apply a bead of Mill-Pac Black sealant to the top section of the Ø4” (10 cm) by 5” (12.5 cm) ue collar
adaptor previously installed into the replace ue outlet. Slide the Ø4” (10 cm) ex vent over the ue
collar and secure with three (3) sheet metal screws evenly spaced.
11. Place a bead of high temperature silicone on the intake collar of the replace, slide the Ø6⅝” (16.25
cm) ex intake liner over the collar, secure the ex liner with three (3) sheet metal screws evenly
spaced.
12. On the outside of the exterior wall, apply a bead of Mill-Pac Black sealant to the Ø4” (10 cm) pipe of
the vent terminal. Slide the ex liner onto the vent terminal and secure with three (3) sheet metal
screws evenly spaced.
13. Place a bead of high temperature silicone on the intake collar of the vent terminal, slide the Ø6⅝”
(16.25 cm) ex intake liner over the collar, secure the ex liner with three (3) sheet metal screws
evenly spaced.
