Maintenance And Service
ROUTINE MAINTENANCE:
IMPORTANT NOTE REGARDING FIRST FIRE UP: When the unit is turned on for the rst time, it
should be turned onto high without the fan on for the rst 4 hours. This will cure the paint, logs, gasket
material and the other products used in the manufacturing process. It is advisable to open a window or
door, as the unit will start to smoke and can irritate some people. After the unit has gone through the
rst burn turn the unit off including the pilot, let the unit get cold then remove the glass door and clean
it with a good gas replace glass cleaner, available at your local ENVIRO dealer.
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. Depending upon the amount of use, cleaning should be required no more than two or three
times per season.
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.
OPENING THE DOOR
1. Turn unit off and wait until the appliance has cooled down.
2. Open the lower louver panel.
3. Use a 5/16” socket to undo the two bolts at the bottom corners of the door.
4. Swing door out, then lift up and out to remove.
5. Ensure the door is properly fastened after cleaning before attempting to re-light the appliance.
CLEANING THE GLASS:
When the replace is cool, remove the face of the replace along with the glass. 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 on the glass, a temporary problem. The glass will
need cleaning after the replace has gone through 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.

Maintenance And Service
REPLACING THE DOOR GLASS:
The glass in the replace is a high temperature 5 mm 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.
It is highly recommended that the removal and replacement of the glass from the door be done by a
licensed or qualied service person.
To Replace:
1. Open the door and remove the glass carefully.
2. Install the new piece of glass with the large bulb in the gasket tape against the unit.

CLEANING THE INSIDE OF THE FIREBOX:
1. Remove door.
2. Remove the logs carefully, as they are very fragile. Gently remove all the embers and rock wool and
place on a paper towel.
3. Vacuum the bottom of the rebox thoroughly. Carefully clean any dust off the logs and brick panels and
remove any lint from the burner and pilot. A clean 2” (5 cm) paint brush will work too. At this time,
inspect the burner pan for cracking or severe warping. If a problem is suspected, contact the dealer.
4. Replace the logs and embers carefully as in the “Secondary Installation - Log Set and Ember
Installation” section.
5. Reseal the door.
6. Re-light the pilot following the instructions on the attached label.
CLEANING 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.

VENTING:
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.
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 close to the draft hood relief opening. 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.
NOTE: The draft hood must be in the same pressure zone as the air inlet. To inspect draft from the
front of the unit, locate the ” tube between the louvers and check for a draft using smoke. A vacuum
or suction into the tube will indicate proper drafting.
This model can be vented with 3” aluminum or stainless steel ex vent and/or certied Type B Gas Vent.
The ue collar of the appliance will t inside a standard 3” 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.
VENTING FIREPLACE INSERTS:
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 Enviro ACCENT 20 may be installed and vented into any solid fuel replace
that has been installed in accordance with the National, Provincial/State and
local building codes and has been constructed of non-combustible materials.
An approved full length of chimney liner and rain cap must be used. A
throat connector or ashing must be installed to ensure a tight seal for
top performance, safety and efciency. Carefully follow the manufacturers
instructions that accompany the chimney liner kit.
Install sealed throat connector or ashing to prevent leakage of room air up
through chimney.
Measure the height of the chimney beforehand and purchase the appropriate
kit. Never attempt to over stretch a exible liner to accommodate the height
of the chimney.
Make sure that all chimney clean outs are tightly tting and will not permit air
to leak into the chimney.
The chimney must be clean, in good working order and constructed out of
non-combustible materials. Any ue damper must be removed or blocked
permanently in the open position.

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 (shown in Figure 11), and a few of the
Figure 11. Empty rebox with grate and locator pins.
Placement pins for Back Log
Figure 11: This is how the re
box looks with only the brick
panels in place. This points out
the two (2) placement pins for
the back log on the burner.
Figure 12: The rst log to be
placed is the back log, it has
two (2) placement pins.
Note: The back log may t
tight against the back of the
rebox.

logs come with placement pins,
notches and ledges, which make
alignment easier. Using the
pictures provided, carefully set
the logs in place (see Figures 12
through 16).
NOTE: The logs are fragile
and should be handled
gently.

create a realistic look. Bags of
ceramic ber embers. Place the
embers irregularly around the
burner.
Figure 16. Complete log set-up with embers.
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.
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.

Figure 17. Accent 20 complete log set-up with embers burning.
Figure 17: The Accent 20 burning with a good ame.
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.
IMPORTANT NOTE RE FIRST FIRE UP: When the unit is turned on for the rst time, it should be
turned to high without the fan for the rst 4 hours. This will cure the paint, logs, gasket material and
the other products used in the manufacturing process. It is advisable to open a window or door, as the
unit will start to smoke and can irritate some people. After the unit has gone through the rst burn, turn
the unit off including the pilot, let the unit cool then remove the glass door and clean it with a good gas
replace glass cleaner, available at your local ENVIRO dealer
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 above. If new/more embers and rock wool is required, contact your nearest
ENVIRO dealer.
Never operate the replace with the glass door removed.
