WARNING
Thisreplacehasnotbeentestednorapprovedtohavea
television or other electrical appliance installed above it.
Clearance from bottom of replace to ceiling is 84 inches. Clearance
from side of replace to adjacent sidewall is 6 inches.
Television Considerations
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 Sys-
tems 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.
CLEARANCES
Do not attach combustible material to the mantel of your replace.
This is a re hazard.
Figure 5
Note: Generic Firebox shown.
No greeting cards, stockings or ornamentation of any type should be
placed on or attached to the replace. This is a heating appliance.
The ow of heat can ignite combustibles.

Note: Generic Firebox shown.
COMBUSTIBLE MATERIAL
Figure 3
Figure 4

35362-5-0217 Page 11
Termination clearance for buildings with combustible and noncombustible exteriors.
Vertical Sidewall Installations
Important! Minimum clearance between vent pipes and combustible
materials is 3 inches (76 mm) on top, and 1 inch (25 mm) on bottom
and sides.
Important! When vent termination exits through foundation less
than 20 inches (508 mm) 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: It is always best to locate the replace in such a way
that minimizes the number of offsets and horizontal vent length.
Since it is very important that the venting system maintain its balance
between the combustion air intake and the ue gas exhaust, certain
limitations as to vent congurations apply and must be strictly
adhered to.
Figure 7
VENT TERMINATION CLEARANCES
The graph showing the relationship between vertical and horizontal
side wall venting will help to determine the various vent lengths
allowable.
The horizontal vent run refers to the total length of vent pipe from
the ue collar of the replace to the face of the outer wall.
The maximum horizontal vent run is 20 feet (6.10 m) when the
vertical vent rise is 8 feet (2.44 m). See Page 22, Figure 33.
Venting termination shall not be recessed into wall or siding.

Installing a New Main Gas Cock (Check Local Code)
Each appliance should have its own manual gas cock.
A manual main gas cock 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 liqueed 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.
Neveruseanexposedametocheckforleaks.Appliancemust
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with

The appliance 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 (3.5 kPa).
The appliance 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 (3.5 kPa).
Attention! If one of the procedures results in pressures in excess
of 1/2 psig (14” w.c.) (3.5 kPa) on the replace gas valve, it will
result in a hazardous condition.
Checking Manifold Pressures
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5 inch w.c. (.871 kPa) at the valve
outlet with the inlet pressure to the valve from a minimum of 4.5 inch
w.c. (1.120 kPa) for the purpose of input adjustment to a maximum
of 14.0 inch w.c. (3.484 kPa). Propane gas models will have a
manifold pressure approximately 10.0 inch w.c. (2.49 kPa) at the
valve outlet with the inlet pressure to the valve from a minimum of
10.8 inch w.c. (2.68 kPa) for the purpose of input adjustment to a
maximum of 14.0 inch w.c. (3.484 kPa).

INSTALLATION
Framing
Fireplace framing can be built before or after the replace is set
in place. Framing should be positioned to accommodate wall
covering and replace facing material. The replace framing should
be constructed of 2 x 4 lumber. The framing headers may rest on
the replace standoffs. Refer to Figure 13 for minimum framing
dimensions.
ATTENTION: Measure replace dimensions and verify framing
methods and wall covering details before framing construction be-
gins.
Framing dimension "A" includes a six inch clearance for
standoffson rebox.After installing reboxinto framing,
thenishedwallsurfacemustcoverthesixinchopening

Vent Pipe Clearance
NOTE: Maintain two inches of clearance around vertical vent pipe
on rst twelve inches. See Figure 16.
For horizontal vent, maintain a minimum one-inch clearance to
the bottom and sides of the vent, and three-inch clearance to
combustibles above the vent pipe. See Figure 17.
NOTE: A two-inch clearance around pipe for the rst twelve inches
above the replace is required.

INSTALLATION (continued)
Attention: Cold climate installation recommendation: When
installing this unit against a non-insulated exterior wall, the outer
walls should be insulated to conform to applicable codes.
Finish the joint between the replace and wall with sealant rated
at 300 degrees F, or tile/stone over the joint.
Vent Runs
In planning the installation for the replace, it is necessary to install
certain components before the appliance is completely positioned
and installed. These include the direct vent system, gas piping for
the appliance and the electrical wiring. (If the fan option is used.)
The appliance can be mounted on any of the following surfaces:
1. A at, hard combustible (burnable) surface.
2. A raised wooden platform.
3. Four corner supports. (Example: Four concrete masonry blocks.)
These supports must be positioned so they contact all four
perimeter edges on the bottom of the unit.
Securing the Vent Pipe to the Fireplace
1. Hand bend the tabs up on the Outer Wrapper Top Assembly
as shown in Figure 20.
Figure 20
2. Insert the rst piece of pipe and secure with 4 screws through
the tabs and into the pipe. See Figures 21 and 22.

Begin the vent system installation by selecting the type of venting
to be installed and the path that it will take. Verify that clearances
are met throughout the path of the venting system.
Determine how the vent system will be terminated out the side of
the house or through the roof. Verify clearances for the termination.
When selecting a vent system for use with the replace, refer to
the “Special Vent Systems” section in this manual to determine
what systems are acceptable. Check all clearances and venting
components. Identify if any problems existing in the vent system.
Use Figure 33 on Page 22 for venting to eliminate issues after
installation. Check pipe diameter on vent system and replace to
verify the size is the same.
NOTICE: All outer connection joints must be sealed with aluminum
tape, screws or silicone sealant rated above 300°F/149°C. The inner
ue joints do not require any sealant.
