different climates and venting arrangements. Start
the pilot and then the burner. Make sure the pilot flame is burning normally and none of the burner ports
are plugged. Let the fireplace burn for roughly fifteen9minutes and then examine the flames, compare
the flames to Figure 16.
The ideal flame will be blue at the base and light orange above. The flames should be of medium height.
If the flames look like this, no venturi adjustment is needed. If the flames are fairly short and mostly blue,
the fireplace is getting too much air. Therefore, the venturies should be closed slightly until the correct
flames are achieved. Flames that are very orange, with tall, dark, stringy tips, are not getting enough air.
Open the venturi until the flames clean up. If the venturi is opened, or closed all the way, and the correct
flames cannot be attained, turn off the gas and contact the dealer.
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.

pins out of the hinges (see figure 5).
4. Ensure the door is properly fastened after cleaning before
attempting to re-light the appliance.
Push up
and remove door.
Figure 5: Removing the Door.
Cleaning The Glass:
Allow the glass to cool before cleaning. It will be necessary to clean the ceramic glass periodically.
During a cold start up, condensation will sometimes form on the glass. This is a normal condition with
all gas fireplaces and stoves. However, this condensation can allow dust and lint to cling to the glass
surface. Initial paint curing of the appliance can leave behind a slight film on the glass. This is a temporary
problem. Depending upon the amount of use, cleaning should be required no more than two or three
times per season.
To clean the door, use a mild glass cleaner and a soft cloth or a glass cleaner available from your Enviro
dealer. Abrasive cleaners will damage the glass.
Important note: When the unit is turned on for the first time, It should be turned onto high without
the fan on for the first 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 first 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 fireplace glass
cleaner.
To Replace Door:
The glass in this appliance is an integral part of the door assembly. If the glass is damaged or broken a
replacement inner door with glass assembly must be purchased.
The glass in this appliance is ceramic. Remove the door with glass, a new door assembly must be
purchased from an ENVIRO dealer (part # EC-063). Do not use a substitute materials; it will void
the warranty.
Cleaning The Firebox:
1. Turn off the unit and allow it to cool down completely.
2. Remove the logs carefully from the firebox. Gently remove the embers and place on a piece of paper
towel, until ready to replace.

Maintenance and Service
3. Vacuum the bottom of the firebox thoroughly. Carefully clean off any dust on the logs and remove any
lint from the main burner and pilot burner.
4. After carefully replacing the log and embers in their correct positions (see Secondary Installation Installation of Log Set and Embers), and the door has been resealed, re-light the pilot, following the
instructions on the lighting label attached to the unit.
Cleaning Plated Surfaces:
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 not cool. Do not use other cleaners as they may leave a
residue, which can become permanently etched into the surface.
Burner Removal:
The burner may need to be removed for a few reasons, including cleaning under the burner, converting
the unit to a different gas type, or to replace the burner altogether. Proceed only when the unit has
completely cooled down.
1.Remove the door as shown in the Maintenance

This basic venting configuration shown are rough
guidelines only. Follow national and local codes for other
installation options.
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 locked permanently
in the open position.
• The chimney must be clean, in good working order and
constructed out of non-combustible materials.
• Make sure that all chimney clean-outs are tightly fitting
and will not permit air to leak into the chimney.
• Make all gas connections and check for leaks.
See vent manufacturer’s instructions for vent system
clearances to combustibles and vent terminal clearance
from roof.

Straight Vertical Installation:
This basic venting configuration shown are rough
guidelines only. Follow national and local codes for
other installation options.
For the best venting performance, we recommend a
total vent height in the range of 10 ft (3.0 m) to 30
ft (9.1 m). The total horizontal length depends on the
number of elbows used; a 90° elbow accounts for 5 ft
(1.5 m) of the horizontal run.
The venting should never slope down, a minimum ¼
inch (0.6 cm) rise is needed for every 2 ft (61 cm) of
horizontal is recommended.
If practical, it is best to locate the appliance to permit
the use of shorter horizontals and fewer elbows.

Note: Using two (2) 45° elbows is equivalent to using
one (1) 90° elbow.
The venting rise should be a minimum of 1 ft (31 cm)
from the top of the unit before any horizontal run are
used.

Log Set and Embers Installation:
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 come with five (5) locator pins, and the rear log has one (1)
ledge, which make alignment easier. Using the pictures provided, carefully set the logs in place.
NOTE: The logs are fragile and should be handled gently.
CAUTION: Use only the type of
ember material supplied with this
appliance. Due to the irregular
size of the ember material there
may be more than required. The
use of other foreign materials on
the burners may create dangerous
conditions.
If over time, through cleaning and
servicing, these embers require
replacement, contact the nearest
ENVIRO dealer for replacement
embers.
Figure 19: Step 1 of Log Placement.
Pins for Rear Log
The embers can be place before or
after the logs are placed. A bag of
ceramic fiber embers and rock wool
embers is provided gently remove
the ember material from the plastic
bag. Spread a layer loosely in a
random manner across the burner
tray. Do not allow any embers to
rest against pilot assembly. (See
Figure 20 or 23 for proper ember
placement.)
DO NOT pack this ember material
as this could create an unsafe
condition, leave embers loose
