B. Design and Installation Considerations

NOTICE: Check building codes prior to installation.

•Installation MUST comply with local, regional, state and national codes and regulations.

•Consult insurance carrier, local building inspector, ﬁre ofﬁcials or authorities having jurisdiction over restrictions, installation inspection and permits.

Before installing, determine the following:

•Where the ﬁreplace is to be installed.

•The vent system conﬁguration to be used.

•Gas supply piping.

•Electrical wiring.

•Framing and ﬁnishing details.

•Whether optional accessories—devices such as a fan, wall switch or remote control—are desired.

C. Draft

Draft is the pressure difference needed to vent ﬁreplaces successfully. When a ﬁreplace is drafting successfully, all combustion byproducts are exiting the home through the chimney.

Considerations for successful draft include:

•Preventing negative pressure

•Location of ﬁreplace and chimney

NOTICE: Hearth & Home Technologies assumes no responsibility for the improper performance of the ﬁreplace system caused by:

•Inadequate draft due to environmental conditions

•Downdrafts

•Tight sealing construction of the structure

•Mechanical exhausting devices

•Improper location of the chimney

D. Negative Pressure

WARNING! Risk of Asphyxiation! Negative pressure can cause spillage of combustion fumes and soot. Fire must draft properly for safe operation.

Negative pressure results from the imbalance of air avail- able for the ﬁreplace to operate properly. It can be stron- gest in lower levels of the house.

Causes 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 such as:

-Recessed lighting

-Attic hatch

-Duct leaks

To minimize the effects of negative air pressure:

•Install the outside air kit with the intake facing prevailing winds during the heating season

•Ensure adequate outdoor air for all 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

NOTICE: Hearth & Home Technologies Inc. recommends the use of direct vent ﬁreplaces in basements.
