2 PLANNING FOR FIREBOX INSTALLATION
2.1 Clearances
The NetZero Firebox is designed as a zero-clearance enclosure for a NetZero Burner. The NetZero Firebox is designed
to provide the required clearances to combustible framing.
WARNING: If the information in these instructions is not followed exactly, a fire or explosion may result, causing
property damage, personal injury, or loss of life.
- Do not move or relocate the appliance while in use.
- For indoor use and in housing only. Minimum temperature of use is 50°F (10°C).
- Do not place any objects on the top of the burner except attached accessories.
- For service purposes, the surrounding area must allow for easy removal of the burner.
- Keep children, animals, and unauthorized persons at a safe distance at all times and never leave them unsupervised
when the appliance is on or hot.
- A Class B fire extinguisher must be located in close proximity to the appliance in case of fire.
- No heat-sensitive or flammable objects can be placed within a 40-inch radius from, or directly above, the burner.

5
2.2 Ventilation & Required Room Size
Open fires consume oxygen. Use only in well-ventilated areas and those that are protected from the draft effects of
cross ventilation. When selecting a location for the appliance it is important to consider the recommended minimum
room sizes and clearances to walls and combustible materials (see Table A). An air exchange rate of 1/hour is
recommended.
In a house of typical construction, that is, one that is not of unusually tight construction due to heavy insulation and
tight seals against air infiltration, an adequate supply of air for combustion and ventilation is provided through
infiltration. The unvented decorative appliance should be installed in a room where at least 200 ft.3(5.7 m3) of air
space is provided for each 1,000 BTU per hour of unvented decorative appliance rating (at maximum burner
adjustment). See Table A for recommended minimum room size.
If the burner is installed in a room smaller than the recommended minimum room size, or in a home of unusually
tight construction, the door(s) to adjacent room(s) should be kept open or a window to the outside should be
opened at least 1 inch (25.4mm) to guard against potential buildup of indoor air pollution.
The decorative appliance may only be installed in a bathroom or bedroom if the room meets the recommended
minimum room size.

3.6 Installing Finishing Material
3.6.1 Definitions
Combustible materials - Materials made of, or surfaced with, wood, compressed paper, plant fibers, plastics, or
other material that can ignite and burn, whether flame produced or not, or plastered or unplastered, shall be
considered combustible materials.
Non-combustible materials - Materials which will not ignite and burn. Such materials are those consisting entirely of
steel, iron, brick, tile, concrete, slate, glass, or plasters, or any combination thereof. Materials that are reported as
passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750C shall be
considered non-combustible materials. HardieBacker® cement board is a preferred material for finishing the wall
above the firebox where non-combustible material is required. Do not use WonderBoard® or Durock® brand cement
board as these contain polymers that will smell and break down when heated.
3.6.2 Wall Finishing Options
A 2-inch wide deflector is included with the firebox. If the deflector is installed at the top opening of the firebox as
shown below combustible finishing material can be installed directly above the deflector. This would include
common wall finishing materials like gypsum board (drywall). The finishing material used must not be thicker than 2
inches.
WARNING: Do not use wall finishing materials that are heat sensitive such as wallpaper or veneered wood around
the firebox.
Option A
Standard solution
(combustible materials with deflector)
a) Use the included rivets or screws to install the deflector to the top of the firebox.
b) If desired, install the optional finishing guides along the sides and bottom of the firebox. See the section on
optional finishing guides for additional information.
c) Install wall finishing material around the opening of the firebox.

16
If the deflector is not used, non-combustible finishing material must be used above the firebox opening. The non-
combustible finishing material must extend to a height of at least 40 inches above the floor of the firebox.
HardieBacker® cement board is a preferred material for finishing the wall above the firebox where non-combustible
material is required. Do not use WonderBoard® or Durock® brand cement board as these contain polymers that will
smell and break down when heated.
Option B
Alternative solution
(non-combustible materials without deflector)
a) If desired, install the optional finishing guides along the sides, top, and bottom of the firebox. See the section on
optional finishing guides for additional information.
b) Complete the construction by finishing the wall around the firebox. Ensure the finishing material above the
opening are non-combustible materials.

17
3.6.3 Optional Finishing Guides
The firebox comes with optional finishing guides. These guides install to the front face of the firebox. They provide
an edge that can be finished up to with finishing material and will then cover the cut edge of the finishing material.
The guides protrude 1/2 inch from the face of the firebox. For the best results use 1/2 inch thick finishing material
with the guides.
Install the guides using the included rivets or screws. If using the deflector at the top of the firebox the deflector will
serve as the top guide. After installing the guides verify that the guides meet in the corners and that the opening
matches the dimensions below.
