Empire recommends the following:
•Keep this checklist visible on the replace until the installation is complete.
•Photograph the installation and copy this completed checklist for your le.
Comments:Further description of the issues, who is responsible (Installer/Builder/Other, etc) and corrective action needed:
Read all instructions before starting installation and
follow them carefully to ensure safety. Failure to follow
the instructions will void the warranty and may cause a
rehazard.
The warranty will be voided by, and the warranter disclaims
any responsibility for the following actions:
• Installation by anyone other than the dealer or his agent.
• Installation of any damaged replace or component.
• Modication of the replace or direct vent system.
• Installation other than as instructed by Empire Comfort
Systems.
• Improper positioning of logs, glass door, or accessories.
• Installation and/or use of any component part not
manufactured or approved by Empire Comfort Systems.
Installing a television above a replace has become increasingly
popular; however, the area above any replace gets hot and most
TV manufacturers recommend against placing their products
near a heat source.
If you install a television above this replace, Empire Comfort
Systems accepts no responsibility for damage or injuries. Follow
the television manufacturer’s installation instructions, including
any recommendations regarding proximity to heat sources.
If you have a TV above your replace, turn off the replace and
let it cool completely before servicing or touching any buttons on
the TV.
All correspondence should refer to complete Model Number, Serial
Number and type of gas. Fill out the Homeowner Reference Section.
(See Page 3).
Unpacking The Fireplace
1. Cut away shrink-wrap material around the unit.
Retain instruction manual and instruction sheets.
2. Remove non-combustible board from the rear of the
replace, and place in a safe location. It will be needed
for installation.
3. Get help to lift replace.

BEFORE YOU START (CONTINUED)
Preparation
This replace and its components are safe when installed
in accordance with this manual. Report any parts damaged
in shipment to your dealer. Do not install the replace with
damaged, incomplete or substitute parts.
Installation Considerations
• Gas supply piping – right or left side entrance
• Electrical supply and connections 120V, 60Hz, 1 Amp,
right side entrance
•Allowable replace mounting surfaces:
1. A at, hard, combustible or non-combustible surface
2. A raised platform of combustible or non-combustible
material.
3. The four corners of the replace onto non-combustible
material so that contact is made on all four perimeter
edges on the bottom of the replace – such as on cinder
blocks (where allowed by local codes).
•If the replace is installed directly on carpeting, tile or other
combustible material other than wood ooring, it should be
installed on a metal or wood panel extending the full width
and depth of the replace.
•This replace is designed to be installed in a zero-clearance
enclosure. Combustible material can come in contact with
the side standoff spacers, and the replace can be secured
to combustible framing with the framing brackets provided
with the replace.
Planning the installation
First determine where the replace will be located and what
accessories will be installed.
Your location must allow for:
•Venting – either vertical or horizontal. Choose a vent
conguration, (See Pages 34-36) and make sure the required
access through attics and walls is not blocked by other utilities
such as water lines, sewer vents, gas lines, etc. If access
is blocked, you will need to move the utilities or relocate the
replace.
•Gas supply piping (right or left side of entrance) – (See pipe
size and specs on Page 17).
•Electrical supply requirements
(120V, 60Hz, 1 Amp) (right side entrance)
•Proper framing required for installation of the replace.
See framing dimensions on (See Page 22).
•Finishing the replace – drywall thickness, tile or stone
thickness, and the desired decorative accessories can affect
how you frame the opening and how you attach the nailing
anges to set the proper depth. (See Pages 23 - 24) for
nishing details, before you begin.
Accessories
Most accessories install much more easily before tting the
replace to the opening.
For example, it takes just 10-15 minutes to install the blower side
before it’s framed in. Once the replace is framed in, it takes up
to an hour.

Vertical Sidewall Installations
Important! Minimum clearance between vent pipes and
combustible
materials is 3 inches (76 millimeter) on top, and 2
inches (25 millimeter) on bottom and sides.
Important! When vent termination exits through foundation less
than 20 inches (508 millimeter) below siding outcrop, the vent
pipe must extend outward so that the horizontal vent termination
is located ush to, or beyond the outcrop siding.
Information on Various Venting Routes and Components
Important: Locate the replace in such a way that minimizes the
number of offsets and horizontal vent length.
Venting system must maintain a balance between the
combustion air intake and the ue gas exhaust. Limitations to
vent congurations apply.
Clearances are to heat resistant material (i.e. wood, metal). This
does not include vinyl. Empire Comfort Systems Inc. will not be held
responsible for heat damage caused from terminating under vinyl

that a exible appliance connector cannot exceed three feet in length.
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required
by the National Fuel Gas Code that a drip leg be installed near the
gas inlet. See Figure 25. This should consist of a vertical length of
pipe tee connected into the gas line that is capped on the bottom
in which condensation and foreign particles may collect.
Installing a New Main Gas Supply Valve (Check Local Code)
Each appliance should have its own manual gas supply valve.
A manual main gas supply valve should be located in the vicinity of the
unit. Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liqueed petroleum gases.

The gas lines must be checked for leaks by the installer. This should
be done with a soap solution watching for bubbles on all exposed
connections, and if unexposed, a pressure test should be made.
NOTICE: The millivolt gas controls are equipped with a captured
screw type pressure test point, therefore it is not necessary to provide
a 1/8 inch test point up stream of the control.
On direct ignition valves, hex plugs may be replaced with hose ttings
for pressure checks, then reinstalled before operating replace.
When using copper or ex connector use only approved ttings.
The replace and its individual shut off valve must be disconnected
from supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5kPa).
The replace must be isolated from the gas supply piping system
by closing its individual manual shut off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 psig (3.5kPa).

Checking Manifold Pressures
Both Propane and Natural gas valves have a built-in pressure regulator.
Natural gas models will have a manifold pressure of approximately 3.5
inches w.c. (.871kPa) at the valve outlet with the inlet pressure to the
valve from a minimum of 4.5 inches w.c. (1.120kPa) for the purpose
of input adjustment to a maximum of 14.0 inches w.c. (3.484kPa).
Propane gas models will have a manifold pressure approximately 10.0
inches w.c. (2.49kPa) at the valve outlet with the inlet pressure to the
valve from a minimum of 10.8 inches w.c. (2.68kPa) for the purpose
of input adjustment to a maximum of 14.0 inches w.c. (3.484 kPa).
