Operating Instructions
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.
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 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
Glass Removal and Glass Cleaning section.
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.
BLOWER SPEED (OPTIONAL):
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 4).
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.

BURNER LIGHTING:

Maintenance And Service
ROUTINE MAINTENANCE:
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. See Secondary Installation.
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
cold 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. Replace the logs and embers as in the Secondary Installation section.
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). 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.
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 discolored 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.
