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.

Framing and finishing details.

Whether optional accessories are desired.

C. Draft

Draft is the pressure difference needed to vent fireplaces successfully. When a fireplace is drafting successfully, all combustion by-products 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 positioning of the chimney in a not-recommended location on the roof.

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:

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: The fireplace provides some outside air for combustion. Other methods may be necessary if more air is required.

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