For Your Safety, Read Safety Precautions And
Lighting Instructions Before Operating
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.
TURN OFF UNIT:
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. 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 two to 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 Enviro dealer. See “DOOR REMOVAL” and “CLEANING THE
GLASS” sections.
REMOTE CONTROLS - OPTIONAL:
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.
BLOWER SPEED:
The blower will come on only when the replace is up to temperature (approximately
20 minutes). Turning the fan control knob will change the speed of the fan. To turn
the blower off, turn the knob COUNTER-CLOCKWISE until it “clicks” off (Figure 6).
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
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.
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.
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 is cool, remove the face of the replace along with the glass door. See “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 after the replace has cooled off from the rst burn and about two weeks after rst burn. 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 THE 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 PLATED SURFACES:
Painted 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.

FUEL CONVERSION:
Warning: This conversion kit shall be installed by a qualied service agency in accordance with the
manufacturer’s instructions and all applicable codes and requirements of the authority having

B-VENT MODEL:
WARNING: This appliance has been designed to operate by drawing combustion air and dilution air
from the room. It is also designed to draw room air for proper heat circulation from the sides of the
unit. Blocking or modifying the louvers in any way can create hazardous situations, either through poor
venting or by overheating. It is important that this unit has sufcient air circulation for proper venting
and combustion. Provisions must be made for the supply of adequate combustion and ventilation air.
These openings must not be blocked. The appliance must not be connected to a chimney ue servicing
a separate solid fuel-burning appliance.
AUTOMATIC FLUE GAS SPILL SWITCH - B-VENT MODEL ONLY:
NOTE: This heater must be properly connected to a venting system. This heater is equipped
with a vent safety shutoff system designed to protect against improper venting of combustion
products. This safety switch is located on the rear of the appliance. If the switch trips more
than once, the venting should be inspected by a qualied service technician for possible
blockage or severe down draft conditions.
WARNING: Operation of this heater when not connected to a properly installed and maintained
venting system can result in carbon monoxide (CO) poisoning and possible death.
The draft hood must be in the same pressure zone as
the air inlet. Inspect for draft from the front of the unit
at the ” tube shown in Figure 10. Check for a draft
using smoke; a vacuum or suction into the tube will
indicate proper drafting. If air is blowing out of the tube
the problem must be corrected before the unit can be
started.
This model can be vented with 4” aluminum or stainless
steel ex vent and/or certied Type B Gas Vent. The
ue collar of the appliance will t inside of a standard
4” vent and may be fastened directly to the vent. Check
periodically that the vent is unrestricted and an adequate
draft is present when the unit is in operation. Figure 10: Draft check.

DIRECT VENT MODEL:
WARNING: This appliance has been designed to draw room air for proper heat circulation
from the sides of the unit. Blocking or modifying the louvers in any way can create hazardous
situations.
This model is vented with two (2) 3” aluminum or stainless steel ex vent leading into a co-linear to
co-axial vent adaptor and using a vertical termination cap. The ue collars of this model will t inside of
standard 3” vent and may be fastened directly to the vent. The Exhaust vent is on the right of the ue
connector. The Air Intake is on the left side of the vent collar plate (this outlet is not in the center, it is off
to one side of the vent collar plate.)
Check periodically that the vents are unrestricted. Also ensure that all direct vent pipes have been
properly sealed and installed after routine inspection or cleaning. The air intake and exhaust pipes must
be installed in the correct locations on the removable connector.
PREPARING YOUR SIENNA FOR INSTALLATION:
• Remove the packaging from the appliance and surround panels; check to make sure there is no
damage. Carefully check the glass door. Do not use the unit if it is damaged. In the event damage is
found, please report it to both the courier and your dealer as soon as possible.
• Carefully clean the replace and ue before installing the stove. Failure to do so may result in fumes
or dirt being blown into the room and may cause a re leading to death or serious injury.
1. Remove the unit from the box and remove all packaging material from the appliance.
2. Remove door. See “DOOR REMOVAL”.
3. Remove log and ember set and all wrapping material from the stove. Remove wrapping material from
log and embers and check for any damage. If damage is observed, do not use unit and contact your
local dealer.
4. Remove the vent collar plate from the top of the stove by unscrewing the two (2) T-20 Torx screws
located on the center top of the stove. Slide the collar plate backwards. If the replace that the unit
is to be installed into is high, the collar plate does not need to be removed. Properly secure the vent
collar plate to the exible vent pipe liner(s) previously installed in the chimney. Be careful not to over-
stretch the liner(s).
5. Place the unit part way into the replace. Connect the replace insert’s exible gas line to the
household gas supply, using locally approved methods. Place the electric cable so it can be connected
to the power supply.

Install sealed throat connector or
flashing to prevent leakage of room air
up through chimney.
DV Only: Before installing vent
liners, mark each liner on both ends
to designate which is the intake and
the exhaust.
Measure the height of the chimney
beforehand and purchase the
appropriate kit. Never attempt to over-
stretch a flexible liner to accommodate
the height of the chimney.
Any flue damper must be removed or
blocked permanently in the open
position.
The chimney must be clean, in good
working order and constructed of non-

LOG SET AND EMBER INSTALLATION:
NOTE: The logs are fragile and should be handled gently.
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, and a few of the logs come with locator pins, notches and ledges,
which make alignment easier. Using the pictures provided, carefully set the logs in place (see Figures 24
through 29).
Figure 24. Empty rebox with grate and locator pins.

Figure 25: The left log and
the right log both have two
(2) holes in them that will rest
over their corresponding two
(2) locator pins pointed out in
Figure 24.
Figure 26: The bottom of the
left/center log will rest over
the locator pin on the burner
and against the grate. The top
half of the log must rest against
