D. High Altitude Installations
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
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.
• Gas supply piping.
• Electrical wiring.
• Framing and finishing details.

2 Getting Started
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.
These appliances must be installed outdoors.
The Dakota 42-B Series Outdoor Gas Fireplace is designed
for outdoor use. It may also be installed in screened porches
and lanais that meet these minimum requirements:
• Minimum porch area - 96 square feet
• Minimum ceiling height - 84 in.
A minimum of two walls can be screened but must be open
to outside ventilation.
• Minimum screen area - 64 square feet
• Minimum screen top height - 80 in.
Refer to Section 3.B. for clearances.

D. High Altitude Installations
U.L. listed gas appliances are tested and approved without
requiring changes for elevations from 0 to 2000 ft in the USA
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.
WARNING
Fire Risk
Explosion Risk
Do NOT change the valve settings.
• This valve has been preset at the
factory.
• Changing valve settings may result in fire
hazard or bodily injury.
• A small amount of air will be in the gas supply lines. When
first lighting appliance it will take a short time for air to
purge from lines. When purging is complete, the appliance
will light and operate normally.
