K. After Fireplace is Lit
Initial Break-in Procedure
• The fireplace should be run three to four hours
continuously on high.
• Turn the fi replace off and allow it to completely cool.
• Remove fi xed glass assembly. See Section 14.I.
• Clean fi xed glass assembly. See Section 3.
• Replace the fi xed glass assembly and run continuously
on high an additional 12 hours.
This cures the materials used to manufacture the fi re-
place.
NOTICE! Open windows for air circulation during fi replace
break-in.
• Some people may be sensitive to smoke and
odors.
• Smoke detectors may activate.
L. Frequently Asked Questions
ISSUE SOLUTIONS
Condensation on the glass
Blue fl ames
Odor from fi replace
Film on the glass
Metallic noise
This is a result of gas combustion and temperature variations. As the fi replace warms, this
condensation will disappear.
This is a result of normal operation and the fl ames will begin to yellow as the fi replace is al-
lowed to burn for 20 to 40 minutes.
When fi rst operated, this fi replace may release an odor for the fi rst several hours. This is
caused by the curing of materials from manufacturing. Odor may also be released from
fi nishing materials and adhesives used near the fi replace. These circumstances may require
additional curing related to the installation environment.
This is a normal result of the curing process of the paint and logs. Glass should be cleaned
within 3 to 4 hours of initial burning. A non-abrasive cleaner such as gas appliance glass
cleaner may be necessary. See your dealer.
Noise is caused by metal expanding and contracting as it heats up and cools down, similar to
the sound produced by a furnace or heating duct. This noise does not affect the operation or
longevity of the fi replace.

B. Design and Installation Considerations
Heatilator B-type vent gas appliances are designed to
operate with all exhaust gases expelled to the outside of
the building, and combustion air pulled from the room.
Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector, fi re offi cials or authorities having
jurisdiction over restrictions, installation inspection and
permits.
Before installing, determine the following:
• Where the appliance is to be installed.
• The vent system confi guration to be used.
• Gas supply piping.
• Electrical wiring requirements.
• Framing and fi nishing details.
• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualifi ed
service technician, service agency or your dealer.
C. Tools and Supplies Needed
Before beginning the installation be sure that the following tools and building supplies are available.
Gloves Safety glasses
Tape measure Framing material
Pliers Flat blade screwdriver
Hammer Phillips screwdriver
Voltmeter Electric drill and bits (1/4 in.)
Plumb line Framing square
Level Reciprocating saw

D. Inspect Appliance and Components
The following B-vent components are needed for installation.
• Fireplace Box
• Pipe Components
• Firestops
• Attic Insulation Shield
• Elbows
• Strapping
• Roof Flashing or Chase Top
• Termination Cap
• Storm Collar
• Carefully remove the appliance and components from
the packaging.
• The vent system components and decorative doors and
fronts may be shipped in separate packages.
• If packaged separately, the log set and appliance grate
must be installed.
• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.
• Read all of the instructions before starting the installation.
Follow these instructions carefully during the installation
to ensure maximum safety and benefi t.
WARNING! Risk of Fire or Explosion! Damaged parts
could impair safe operation. DO NOT install damaged,
incomplete or substitute components. Keep appliance dry.
Hearth & Home Technologies disclaims any responsibility for,
and the warranty will be voided by, the following actions:
• Installation and use of any damaged appliance or vent
system component.
• Modifi cation of the appliance or vent system.
• Installation other than as instructed by Hearth & Home
Technologies.
• Improper positioning of the gas logs or the glass
door.
• Installation and/or use of any component part not
approved by Hearth & Home Technologies.
Any such action may cause a fi re hazard.
WARNING! Risk of Fire, Explosion or Electric Shock!
DO NOT use this appliance if any part has been under wa-
ter. Call a qualifi ed service technician to inspect the appli-
ance and to replace any part of the control system and/or

Heatilator • Caliber Mesh BV Series • 4040-848 Rev G • 10/08 15
E. Negative Pressure
WARNING! Asphyxiation Risk! Negative pressure can
cause spillage of combustion fumes and soot. Fireplace
needs to draft properly for safety.
Draft is the pressure difference needed to vent fi replaces
successfully. Considerations for successful draft include:
• Preventing negative pressure
• Location of fi replace and chimney
Negative pressure results from the imbalance of air
available for the fi replace to operate properly. Causes for
this imbalance include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water heaters
and other combustion appliances
• Clothes dryers
• Location of return-air to furnace or air conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks (recessed lighting, attic hatch
opening, duct leaks)
To minimize the effects of negative air pressure, the following must be considered:
• Install the fresh air kit. Install the intake on the side of
the house towards prevailing winds during the heating
season.
• Ensure adequate outdoor air is supplied for combustion
appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the fi replace.
• Avoid installing the fi replace near doors, walkways or
small isolated spaces.
• Recessed lighting should be of “sealed can” design; attic
hatches weather stripped or sealed; and attic mounted
ductwork and air handler joints and seams taped or
sealed.
• Basement installations should be avoided due to stack
effect. Stack effect creates negative pressure in lower
levels. Hearth & Home Technologies recommends the
use of direct vent fi replaces in basements.
Location of the fi replace and chimney will affect perfor-
mance. As shown in Figure 4.2, the chimney should:
• Be installed through the warm space enclosed by the
building envelope. This helps to produce more draft,
especially during lighting and die-down of the fi re.
• Penetrate the highest part of the roof. This minimizes
the effects of wind turbulence.
• Be located away from trees, adjacent structures, uneven
roof lines and other obstructions.
Offsets can restrict draft so their use should be minimized. Consider the fi replace location relative to fl oor
and ceiling and attic joists.

Framing and Clearances
A. Selecting Appliance Location
When selecting a location for the appliance it is important to consider the required clearances to walls, Figures 5.1 and
5.2.
WARNING! Risk of Fire or Burns! Provide adequate
clearance around air openings and for service access. Due
to high temperatures, the appliance should be located out
of traffi c and away from furniture and draperies.

B. Constructing the Appliance Chase
A chase is a vertical box-like structure built to enclose the
gas appliance and/or its vent system. In cooler climates
the vent should enclosed inside the chase.
NOTICE: Treatment of ceiling fi restops and wall shield
fi restops and construction of the chase may vary with the
type of building. These instructions are not substitutes for the
requirements of local building codes. Therefore, you MUST
check local building codes to determine the requirements
to these steps.
Chases should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems. The chase should not break the outside building
envelope in any manner.
Walls, ceiling, base plate and cantilever fl oor of the chase
should be insulated. Vapor and air infi ltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infi ltration may be an issue, the inside surfaces may
be sheetrocked and taped for maximum air tightness. To
further prevent drafts, the wall shield and ceiling fi re-
stops should be caulked with high temperature caulk to
seal gaps. Gas line holes and other openings should
be caulked with high temp caulk or stuffed with unfaced
insulation. If the appliance is being installed on a cement
slab, a layer of plywood may be placed underneath to
prevent conducting cold up into the room.
