B VENT ONLY: This vent type is identied by the sufx BV. This appliance draws in room air for
combustion and vent dilution air.
This appliance has been tested and approved for installations from 0 feet to 2000 feet (810 m) above
sea level.
In the USA: The appliance may be installed at higher altitudes. Please refer to your American Gas
Association guidelines which state: the sea level rated input of Gas Designed Appliances installed at
elevations above 2000 (610 m) feet is to be reduced 4% for each 1000 feet (305 m) above sea level.
Refer also to local authorities or codes which have jurisdiction in your area regarding the de-rate
guidelines.
In Canada: When the appliance is installed at elevations above 4500 feet (1372 m), the certied high
altitude rating shall be reduced at the rate of 4% for each additional 1000 feet (305 m).
• This appliance has been tested by INTERTEK (Warnock Hersey) and found to comply with the
established VENTED GAS FIREPLACE HEATER standards in CANADA and the USA as follows:

factory built replace in order to allow the insert to t.
Sherwood Industries Ltd. Policy:
Intretek has approved listed factory-built replaces as a certied zero clearance kit, provided that the
following conditions have been met:
1. The removal of any part will not weaken the stuctural integrity of the factory-built replace.
2. The factory-built replace is in good condition.
3. There are no alterations in the form of cutting, bending, or breaking any parts.
4. Firebricks may be removed.
5. A permanent label must be supplied with the insert, with instructions to afx it to the rebox of the
factory-built replace. It will have wording to the effect:
WARNING - THIS FIREPLACE MUST ONLY BE OPERATED WITH A GAS INSERT ONLY -
REMOVAL OF THE INSERT AND THE USE OF SOLID FUEL IS PROHIBITED AND
MAY CAUSE A FIRE HAZARD.
REPLACEMENT PARTS INCLUDE:
Fire bricks, smoke shield, ue damper, glass doors, and rescreens.

Figure 2: Lighting Instruction Label.

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.
3. Place the tape joint in a bottom corner. Use high temperature silicone to ahere the tape to the door
frame.
4. Close door.
The glass must be purchased from an ENVIRO dealer. No substitute materials are allowed.
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.

10
REMOVING BURNER CONTROLS:
1. Shut off gas supply to appliance.
2. Remove surround panels by pulling up then out. Disconnect gas line from the valve. Disconnect
harness at connector on side of unit.
3. Open the door and gently remove the logs. Remove the brick panel as per instructions in “Secondary
Installation - Removing and Installing The Brick Panels”.
4. Remove the burner tray assembly by removing the two screws in the center of the tray. Pull tray up
from the left side, lift tray up and out towards the left.
5. Undo the three screws that hold the burner control tray onto the back rewall. Lift the control tray up
on the left side and pull out. Remove wire connector from rebox.
6. Installation is the reverse. When installing the log set refer to “Secondary Installation - Log Set and
Ember Installation”.
Caution: Bleed lines before lighting and light pilot with door open.
ADJUSTING VENTURI AIR SETTINGS
• There is one venturi and one air shutter on this
appliance. The venturi has been set for installation
at sea level. Some adjustment may be required.
• To adjust for high altitude: open the lower louvers.
Locate the venturi between the burner and
control trays. Loosen the setscrews with a long
screwdriver and rotate the air shutter until an
efcient ame is achieved (refer to Figure 3).
