Operating Instructions
For Your Safety, Read Safety Precautions And
Lighting Instructions Before Operating
TURN OFF UNIT:
Flip switch to OFF to turn off burners only.
If the fireplace 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 first time, it should be turned onto high, with the fan OFF,
for the first 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 first 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 fireplace glass cleaner, available at your local Enviro dealer. See “DOOR REMOVAL” and “CLEANING THE
GLASS” sections.

BLOWER SPEED:
The blower will come on only when the fireplace 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.

Figure 7: Adjusting the venturi air setting.

Maintenance And Service
Warning: Failure to position the parts in accordance with this manual, or failure to use only parts
specifically 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 flame 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
qualified agency.

CLEANING THE GLASS:
When the fireplace is cool, remove the face of the fireplace along with the glass door. 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
fireplaces. However, this condensation can allow dust and lint to cling to the glass surface. Initial paint
curing of the appliance can leave a slight film behind the glass, a temporary problem. The glass will need
cleaning after the fireplace has cooled off from the first burn and about two weeks after first 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 firebox 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
SECONDARY INSTALLATION - 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 fireplace 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 qualified
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 finish, including
cleaners, polish and finger prints. It is important to note that fingerprints and other marks can leave
a permanent stain on plated finishes. To avoid this, give the face a quick wipe with denatured
alcohol on a soft cloth BEFORE lighting the fireplace. 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.

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 sufficient 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 flue 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 qualified service technician for possible
blockage or severe down draft conditions.
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 1⁄4” tube shown in Figure 18. 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 flex vent and/or certified Type B Gas Vent. The
flue collar of the appliance will fit 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.

Check draft with a match
or smoke in a 1⁄4" (6 mm)
tube located here.

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 flex vent leading into a co-linear to
co-axial vent adaptor and using a vertical termination cap. The flue collars of this model will fit inside of
standard 3” vent and may be fastened directly to the vent. The Exhaust vent is on the right of the flue
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.

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 flames 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 30
through 35).

Figure 30: The first log to
be placed is the back log.
It leans on the back of the
firebox, push it back as far
back as you can.

(2) locator pins pointed out in
Figure 30.

Figure 31. First Stage Log Set Installation.

Figure 32: 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
the back log, see Figure 31. The
center spot shown in Figure 31
is a knot in the back log for the
left/center log to rest against.
Ensure the log does not block
any burn ports.

chunks that can be ripped into
smaller pieces.
Figure 34. Fourth Stage Log Set Installation.

WARNINGS: DO NOT pack this
ember material as this could create
an unsafe condition. The pieces
should be lightly placed so they don’t
block any of the burner ports.
DO NOT allow any of the embers to
rest against the pilot assembly.

Figure 35. Fifth Stage Log Set Installation.

Caution: Use only the type of
ember material supplied with this
fireplace. 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.
