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.

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.
