U.L. Listed gas appliances are tested and approved without
requiring changes for elevations from 0 to 2000 feet in the
U.S.A. and Canada.
When installing this appliance at an elevation above 2000 ft,
it may be necessary to decrease the input rating by chang-
ing the existing burner orifice to a smaller size. Input rate
should be reduced by 4% for each 1000 ft above a 2000 ft
elevation in the U.S.A., or 10% for elevations between 2000
and 4500 ft in Canada. If the heating value of the gas has
been reduced, these rules do not apply. To identify the prop-
er orifice size, check with the local gas utility.
If installing this appliance at an elevation above 4500 ft (in
Canada), check with local authorities.

A. Design and Installation Considerations
Heatilator B-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.
Check building codes prior to installation.
• Installation MUST comply with local, regional,
state and national codes and regulations.
• Consult insurance carrier, local building, fire
officials or authorities having jurisdiction about
restrictions, installation inspection, and permits.
CAUTION
When planning an appliance installation, it’s necessary to
determine the following information before installing:
• Where the appliance is to be installed. See Sections 3
and 4.
• The vent system configuration to be used. See Sections
5 and 6.
• Gas supply piping. See Sections 7 and 9.
• Electrical wiring. See Sections 7 and 10
• Framing and finishing details. See Sections 3, 6
and 11.
• Whether optional accessories—devices such as a fan, wall
switch, or remote control—are desired. See Section 16.
Keep appliance dry.
• Mold or rust may cause
odors.
• Water may damage controls.

B. Negative Pressure
Asphyxiation Risk
• Negative pressure can cause spillage of
combustion fumes and soot.
• Fire needs to draft properly for safe
operation.
WARNING
To minimize the effects of negative air pressure, the follow-
ing must be considered:
• Install the outside 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 fireplace.
• Avoid installing the fireplace near doors, walkways or small
isolated spaces.
• Recessed lighting should be a “sealed can” design; attic
hatches weather stripped or sealed; attic mounted duct
work 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 fireplaces in basements.
Location of the fireplace and chimney will affect performance.
As shown in Figure 2.1 the chimney should:
• Be installed through the warm airspace enclosed by the
building envelope. This helps to produce more draft,
especially during lighting and die-down of the fire.
• 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 fireplace location relative to floor and ceiling
and attic joists.

Draft is the pressure difference needed to vent fireplaces
successfully. Considerations for successful draft include:
• Preventing negative pressure.
• Location of fireplace and chimney.
Negative Pressure
Negative pressure results from the imbalance of air avail-
able for the fireplace 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 vents to furnace or air
conditioning.
• Imbalances of the HVAC air handling system.
• Upper level air leaks (recessed lighting, attic hatch
opening, duct leaks).

Heatilator • Caliber BV Series • 4040-262 Rev F • 05/07 7

damage. Damaged parts may impair safe
operation.
• Do NOT install damaged components.
• Do NOT install incomplete components.
• Do NOT install substitute components.
Report damaged parts to dealer.
WARNING
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.
• Modification of the appliance or vent system.
• Installation other than as instructed by Hearth & Home

B. Construct the Appliance Chase
A chase is a vertical boxlike structure built to enclose the gas
appliance and/or its vent system. Vertical vents that run on
the outside of a building may be, but are not required to be,
installed inside a chase.
Construction of the chase may vary with the type of build-
ing. These instructions are not substitutes for the require-
ments of local building codes. Local building codes MUST
be checked.
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 floor of the chase
should be insulated. Vapor and air infiltration barriers should
be installed in the chase as per regional codes for the rest of
the home. Additionally, Hearth & Home Technologies recom-
mends that the inside surfaces be sheetrocked and taped
(or the use of an equivalent method) for maximum air tight-
ness.
To further prevent drafts, gas line holes and other openings
should be caulked with high temp caulk or stuffed with un-
faced insulation. If the appliance is being installed on a ce-
ment slab, we recommend that a layer of plywood be placed
underneath to prevent conducting cold up into the room.
Fire Risk
• Construct chase to all clearance
specifications in manual.
• Locate and install appliance to all
clearance specifications in manual.
