Getting Started
Introducing the Quadra-Fire Gas Fireplaces
Quadra-Fire direct vent gas fireplaces are designed to op-
erate with all combustion air siphoned from outside of the
building and all exhaust gases expelled to the outside.
The information contained in this Installers Guide, unless
noted otherwise, applies to all models and gas control
systems.Gasfireplace diagrams,includingthe dimensions,
are shown in this section.
Pre-install Preparation
Thisgas fireplace and itscomponents 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.
Theventsystemcomponentsare shipped inseparatepack-
ages. The gas logs are packaged separately and must be
fieldinstalled.
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 Quadra-Fire Warranty will be voided by, and Hearth &
Home Technologies disclaims any responsibility for, the
followingactions:
•Installation of any damaged fireplace or vent system
component.
•Modification of the fireplace or direct vent system.
•Installation other than as instructed by Hearth & Home
Technologies.
•Improper positioning of the gas logs or the glass door.
•Installationand/or useof any component part notmanu-
facturedand approvedby Hearth & Home Technologies,
not withstanding any independent testing laboratory or
other party approval of such component part or acces-
sory.
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.
•Framingand 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.

components and terminations (see Figures 5 and 6). Ap-
provedvent system componentsare labeledfor identifica-
tion. This pipe is tested and listed as an approved compo-
nent of the fireplace. The pipe is tested to be run inside an
enclosedwall.There isnorequirement for inspectionopen-
ingsat each jointwithin the wall.There is no required pitch
for horizontal ventruns. NO OTHERVENTING SYSTEMS
OR COMPONENTS MAY BE USED.
Detailedinstallationinstructions are includedwitheach vent
termination kit and should be used in conjunction with this
Installers Guide.
The flame and ember appearance may vary based on the
typeof fuel burned and theventing 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
andtables.Referto thediagramsonthe next severalpages.
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.
Thismodel hasvent startingcollars on both the top and the
back of the unit. Depending upon the installation, decide
which ONE set of starting collars will be used to attach the
vent system. The starting collar sealing cap must remain
