2 Getting Started
A. Design and Installation Considerations
CAUTION
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 about restrictions, installation inspection, and permits.
When planning a fireplace installation, it is necessary to de- termine the following information before installing:
•Where the fireplace is to be installed. See Sections 3 and 4.
•The vent system configuration to be used. See Sections 5 and 6.
•Framing and finishing details. See Sections 3, 6 and 8.
•Whether optional accessories are desired. See Section 12.
Draft is the pressure difference needed to vent fireplaces successfully. Considerations for successful draft include:
•Location of fireplace and chimney
Moisture Resistance:
This outdoor fireplace will shed moderate amounts of water, but is not waterproof. Water and condensing water vapor may enter the chase under certain conditions.
The fireplace will not perform as an exterior wall. Moisture penetration must be considered for construction that places the fireplace in structure walls or on moisture sensitive sur- faces.
When installed on exterior walls: Hearth & Home Tech- nologies recommends that the fireplace chase be con- structed outside the structure’s weather envelope. Where the platform meets the wall, use a flashing detail similar to that required for attached decks. Chase platforms, including hearths should slope away from the structure at 1/8 in. to 1/4 in. per foot. The fireplace can be shimmed level.
When installed on surfaces where water may collect or cause damage: Hearth & Home Technologies recommends that a drainage pan be placed under the unit. This can be constructed of metal, adhesive polymer membrane (such as ice and water shield) or other suitable materials. A means of drainage out of the pan such as tubes or weep holes should be provided. A slope of 1/8 in. to 1/4 in. per foot towards the drain port is suggested. The fireplace can be shimmed level.
Hearths should slope away from the front of the fireplace and chase at 1/8 in. to 1/4 in. per foot. Spark strips must be on top of any combustible hearth materials used for moisture management.
