noted otherwise, applies to all models and gas control
systems. Gas fireplace diagrams, including the dimensions,
are shown in this section.
Pre-install Preparation
This gas fireplace and its components are tested and safe
when installed in accordance with this Installers Guide.
Report to your dealer any parts damaged in shipment,
particularly the condition of the glass. Do not install any
unit with damaged, incomplete, or substitute parts.
The vent system components are shipped in separate pack-
ages. The gas logs are packaged separately and must be
field installed.
Read all of the instructions before starting the instal-
lation. Follow these instructions carefully during the
installation to ensure maximum safety and benefit.
Failure to follow these instructions will void the own-
er’s warranty and may present a fire hazard.
The Heat & Glo Warranty will be voided by, and Heat & Glo
disclaims any responsibility for, the following actions:
• Installation of any damaged fireplace or vent system
component.
• Modification of the fireplace or direct vent system.
• Installation other than as instructed by Heat & Glo.
• Improper positioning of the gas logs or the glass door.
• Installation and/or use of any component part not manu-
factured and approved by Heat & Glo, not withstanding
any independent testing laboratory or other party approval
of such component part or accessory.
ANY SUCH ACTION MAY POSSIBLY CAUSE A FIRE
HAZARD.
When planning a fireplace installation, it’s necessary
to determine:
•Where the unit is to be installed.
•The vent system configuration to be used.
•Gas supply piping.
•Electrical wiring.
•Framing and finishing details.
•Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.
If the fireplace is to be installed on carpeting or tile,
or on any combustible material other than wood
flooring, the fireplace should be installed on a metal
or wood panel that extends the full width and depth
of the fireplace.

Step 3. Installing the Vent System
A. Vent System Approvals
These models are approved to use DVP series direct vent
pipe components and terminations (see Figures 6 and 7).
Approved vent system components are labeled for identifi-
cation. This pipe is tested and listed as an approved com-
ponent of the fireplace. The pipe is tested to be run inside
an enclosed wall. There is no requirement for inspection
openings at each joint within the wall. There is no required
pitch for horizontal vent runs. NO OTHER VENTING SYS-
TEMS OR COMPONENTS MAY BE USED.
Detailed installation instructions are included with each vent
termination kit and should be used in conjunction with this
Installers Guide.
The flame and ember appearance may vary based on the
type of fuel burned and the venting configuration used.
Identifying Vent Components
The vent systems installed on this gas fireplace may in-
clude one, two, or three 90° elbow assemblies. The rela-
tionships of vertical rise to horizontal run in vent configura-
tions using 90° elbows MUST BE strictly adhered to. The
rise to run relationships are shown in the venting drawings
and tables. Refer to the diagrams on the next several pages.
NOTE: Two 45° elbows may be used in place of one
90° elbow. Rise to run ratios in the vent system must
be followed if 45° elbows are used.
This model has a 450 elbow built into it. It may be posi-
tioned to vent either horizontal or vertical. Depending on the
installation, decide which direction the elbow should be fac-
ing. Remove the 8 screws from the corner cover plate. Po-
sition the 450 elbow as desired and replace the corner cov-
er plate with the 8 screws.
