BLDV7 Series Gas Fireplace pRE-INSTALLATION INFORMATION

Fireplace Location
Plan for the installation of your appliance. This includes determining where the unit is to
be installed, the vent configuration to be used, framing and finishing details, and whether
any optional accessories (i.e. blower, wall switch, or remote control) are desired. Consult
your local building code agency to ensure compliance with local codes, including permits
and inspections.
The following factors should be taken into consideration:
• Clearance to side-wall, ceiling, woodwork, and windows. Minimum clearances to com-
bustibles must be maintained.
• This fireplace may be installed along a wall, across a corner, or use an exterior chase.
Refer to Figure 3 for suggested locations.
• Location should be out of high traffic areas and away from furniture and draperies due
to heat from appliance.
• Never obstruct the front opening of the fireplace.
• Do not install in the vicinity where gasoline or other flammable liquids may be stored.
• Vent pipe routing. Refer to Venting section found in this manual for allowable venting
configurations.
• These units can be installed in a bedroom. Refer to National Fuel Gas Code ANSI
Z233.1/NFPA 54 — (current edition), the Uniform Mechanical Code — (current edition),
and Local Building Codes for specific installation requirements.
• These units can be installed in a bathroom.

Only noncombustible materials (i.e. brick, tile, slate, steel, or other materials with a UL fire rating
of Zero) may be used to cover the black painted face of the appliance. It is permissible to bring
combustible wall board to the top and side edges of the black painted face. A 300°F minimum
adhesive may be used to attach facing materials to the black surface. If joints between the finished

* A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA design-certified equipment shutoff valve from your dealer.
For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do not
reduce incoming gas pressure, burner system regulator damage could occur. Install external regulator with the vent
pointing down as shown in Figure 30. Pointing the vent down protects it from freezing rain or sleet.

IMPORTANT: Install main gas valve (equipment shutoff

turning on or shutting off the gas to the fireplace.
Check your building codes for any special requirements for locating equipment shutoff valve to
fireplaces.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe.
Excess sealant in pipe could result in clogged burner system valve.
We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 31. Locate
sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel
supply and burner system. Locate sediment trap/drip leg where trapped matter is not likely to freeze.
A sediment trap collects moisture and contaminants and keeps them from going into the burner

may not run properly.

for your safety read before lighting

WARNING
If you do not follow these instruction
exactly, a fire or explosion may result
causing property damage, personal injury
or loss of life.

A. This appliance is equipped with a pilot which must be lit with built-in piezo ignitor while
following these instructions exactly.
B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next
to the floor because some gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS:
• Turn off all gas to the appliance.
• Open windows.
• Do not attempt to light any appliance.
• Do not touch any electric switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's
instructions.
• If you cannot reach your gas supplier, call the fire department.
C. Use only your hand to push in, or turn the gas control knob. Never use tools. If the knob will
not push in or turn by hand, don't try to repair it. Call a qualified service technician. Force
or attempted repair may result in a fire or explosion.
D. Do not use this appliance if any part of it has been under water. Immediately call a qualified
service technician to inspect the appliance and to replace any part of the control system
and any gas control that has been under water.

cleaning and maintenance BLDV7 Series Gas Fireplace

Vent SysteM
The fireplace and venting system should be inspected before initial use and at least annually by a
qualified field service person. Inspect the external vent cap on a regular basis to make sure that no
debris is interfering with the airflow. Inspect entire venting system to ensure proper function.
Glass Door
Thoroughly clean the inside of the glass door after using the fireplace for ten hours. Periodically clean
the glass door as necessary.
When cleaning the glass, remember:
• Do not remove the glass when hot. Allow glass to cool before removal.
• NEVER use abrasive materials.
• Keep children and pets a safe distance away.
• Never operate the fireplace without the glass door properly secured.
• Never operate the fireplace if the glass is broken.
• Replace any glass that is chipped, cracked, or broken. Replacement glass door assemblies MUST
be supplied by the fireplace manufacturer ­– No substitute materials may be used.
• Handle glass door with care to avoid striking or scratching it on hard objects.
To clean glass door, follow “Glass Removal” procedure outlined in the Final Installation section. Film
deposit on the inside of the glass should be cleaned off using a nontoxic, non-corrosive, non-abrasive,
mild-cleaning solution. Simply apply an adequate amount to the glass and wipe off with a damp cloth.
After all maintenance has been completed, re-install glass door.
Logs
Leave logs installed in the fireplace for cleaning. Vacuum surface of the logs with a brush attach-
ment. If logs must be removed for cleaning, handle carefully by holding gently at each end. Gloves
are recommended to prevent skin irritation from ceramic fibers. If skin becomes irritated, wash gently
with soap and water. Vacuum surface of logs with brush attachment or brush logs with a soft bristle
brush (i.e. clean, dry paintbrush). To place logs back in the fireplace, see “Log Placement” found in
the Final Installation section.
NOTE: Do not use fluids to clean ceramic fiber logs.
Rock wool
Replace or add rock wool as required following installation instructions in the Final Installation sec-
tion of this manual.
