Access Panel
An access panel is not required (see note below for exception), but it is
highly recommended
. It allows for access to the fireplace’s
gas and electrical components for servicing.
NOTE: An access panel at the fireplace is
required
for fireplaces with a power vent to allow access to the power vent
control box for servicing.
Access Panel Size and Location Recommendations:
Size: as large as possible depending on application. Minimum is 10”x10”.
Located within 36 inches of the pilot to the side or back of the fireplace (see “Routing the Gas Line”)
The size and location of the access panel may vary, but in all cases, it must allow the technician to comfortably access and service
the fireplace’s gas and electrical components. These components are attached to the pilot on a flexible gas line and can be moved
within 36 inches of the pilot (located at the center front of the burner) to the side or back of the fireplace.
For ease of access, move the fireplace’s gas and electrical components as close to the access panel as possible
. If there is any
distance between the access panel and the gas and electrical components, the access panel size must be increased
accordingly.
Prior to installation, fireplace dealers/installers should work with the owner, builder, project architects and/or interior
designers to determine the best size and location of their access panel.
If an access panel cannot be incorporated, the alternative method of servicing the gas and electrical components is though the
fireplace. This procedure requires removing the glass panel(s) and interior design media, and lifting the grill, burner, and bottom
pressure release valve. This will increase service time and difficulty. An access panel is always preferred. Fireplace dealers/installers
are advised to consult with their clients regarding the advantages and disadvantages of each service option.
NOTE: If local code requires an access panel, defer to local code requirements.
Protective Cover for Double Glass Fans
Fireplaces with the double glass heat barrier comes equipped with a bottom cover to
protect the fans from damage. This protective cover blocks service access to gas and
electrical components. The protective cover is installed under the front and sides of the
fireplace.
The gas and electrical components are accessible in the following locations on each model
(as shown in the table below).

Chase Area Minimum
The narrowest part of your fireplace chase cannot be smaller than the minimum required heat release size (see “Heat Release
Requirements” on page 16). This ensures the convective heat within the chase passively moves to the heat release at an optimal
rate. To determine if your chase meets this requirement, use the following equation at the narrowest part of the chase.
Chase Area = (Chase Length x Chase Depth) – (Area of the Pipe)
Area of the Pipe:
5”x8” venting = 50.27 in
2
3”x5” venting
*
= 19.63 in

*Used for Power Venting only
Fireplace Chase (Top View)
If the heat release is split into 25/75 portions due to an oversized ledge, the chase only needs to be the size of 75% of the heat
release because 25% of the heat is already being released at the ledge (see “Recessed Ledge Detail” section below for details).
