SAFETY INFORMATION FOR USERS OF LP-GAS
Propane (LP-Gas) is a ammable gas which can cause res
and explosions. In its natural state, propane is odorless
and colorless. You may not know all the following safety
precautions which can protect both you and your family
from an accident. Read them carefully now, then review
them point by point with the members of your household.
Someday when there may not be a minute to lose,
everyone’s safety will depend on knowing exactly what
to do. If, after reading the following information, you feel
you still need more information, please contact your gas
supplier.
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas
because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!
• Do not operate electric switches, light matches, or use your
phone. Do not do anything that could ignite the gas.
• Immediately get everyone out of the area.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
reghters declare them to be safe.
• Use your neighbor’s phone and call a trained LP-Gas service
person and the re department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the area.
• Finally, let the service man and reghters check for
escaped gas. Have them air out the area before you return.
Properly trained LP-Gas service people should repair the
leak, then check and relight the gas appliance for you.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell
the odor of the chemical put into the gas. You must nd
out if you can smell the odorant in propane. Smoking can
decrease your ability to smell. Being around an odor for a time
can affect your sensitivity or ability to detect that odor. Sometimes
other odors in the area mask the gas odor. People may not smell
the gas odor or their minds are on something else. Thinking
about smelling a gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and the odor can fade
under some circumstances. For example, if there is an
underground leak, the movement of the gas through soil can lter
the odorant. Odorants in LP-Gas also are subject to oxidation.
This fading can occur if there is rust inside the storage tank or in
iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That
will take some of the odorant out of the gas, reducing its odor
intensity.
LP-Gas may condense in a closed area, and the odor intensity
could vary at different levels. Since it is heavier than air, there
may be more odor at lower levels. Always be sensitive to the
slightest gas odor. If you detect any odor, treat it as a serious
leak. Immediately go into action as instructed earlier.
SOME POINTS TO REMEMBER
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a “Scratch and Sniff” pamphlet. Use it
to nd out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your LP-
Gas Dealer.
• If you are not qualied, do not perform service, or make
adjustments to appliances on the LP-Gas system. If you are
qualied, consciously think about the odor of LP-Gas prior
to and while lighting burner or performing service or making
adjustments.
• Do not try to light the burner, perform service, or make
adjustments in an area where the conditions are such that
you may not detect the odor if there has been a leak of LP-
Gas.
• Odor fade, due to oxidation by rust or adsorption on walls
of new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks or
cylinders are placed in service. Odor fade can occur in new
tanks, or reinstalled old tanks, if they are lled and allowed
to set too long before relling. Cylinders and tanks which
have been out of service for a time may develop internal rust
which will cause odor fade. If such conditions are suspected
to exist, a periodic sniff test of the gas is advisable. If you
have any question about the gas odor, call your LP-
Gas dealer. A periodic sniff test of the LP-gas is a good
safety measure under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Take the same
immediate action recommended for the occasion when you
do detect the odorized LP-Gas.
• If you experience a complete “gas out,” (the container
is under no vapor pressure), turn the tank valve off
immediately. If the container valve is left on, the container
may draw in some air through openings. If this occurs, some
new internal rusting could occur. If the valve is left open,
then treat the container as a new tank. Always be sure your
container is under vapor pressure by turning it off at the
container before it goes completely empty or having it relled
before it is completely empty.

33858-1-0615Page 8
Important
• Before contacting your dealer or Empire regarding this
replace, please complete the Homeowner Reference
Information above.
• Do not burn solid fuels in this appliance.
• The maximum gas inlet supply pressure is 13 inches for LP
and 10.5 inches for NAT.
• If a replace is equipped with a gas pressure regulator
connect to a xed fuel piping system:
• The required manifold pressure in inches water column
(w.c.) is 10 inches for LP and 3.5 inches for NAT when
on "HI".
• Disconnect the replace and its shutoff valve from the
gas supply piping system during any pressure testing in
excess of 1/2 psi (3.5 kPa).
• Close the shutoff valve to isolate the replace from the
gas supply during any pressure test equal to or less
than 1/2 psi (3.4 kPa).
Moisture Control
• This outdoor replace will shed moderate amounts of water,
but is not waterproof. Water and condensing water vapor
may enter the chase under certain conditions.
• The replace will not perform as an exterior wall. Moisture
penetration must be considered for construction that places
the replace in structure walls or on moisture sensitive
surfaces.
• When installed on exterior walls: Construct the replace
chase outside the structure's weather envelope. Where the
platform meets the wall, use a ashing detail similar to that
required for attached decks. Chase platforms, including
hearths should slope away from the structure at 1/4 inch per
foot. The replace can be shimmed level.
• When installed on surfaces where water may collect or
cause damage: It is recommended a slope of 1/4 inch per
foot towards the drain port. The replace can be shimmed
level.
• Hearths should slope away from the front of the replace
and chase at 1/4 inch per foot.
• We recommend a weather door or bifold door accessory to
protect the replace from moisture. Never install the replace
where moisture cannot drain off easily.
Instructions to Installer
1. Leave instruction manual with owner.
2. Show homeowner the Product Registration Card supplied with
replace.
3. Fill in the Homeowner Reference Information above.
4. Show owner how to start and operate outdoor replace.
Consult your local Building Department regarding regulations,
codes or ordinances which apply to the installation of an outdoor
replace.
WARNING
Any change to this replace or its controls can be dangerous.
Improper installation or use of the appliance can cause serious
injury or death from re, burns, explosion or carbon monoxide
poisoning.
Cleaning Instructions at Installation
This appliance is built using mostly high-grade stainless steel to
resist rust-through. In outdoor applications, all stainless steel will
develop a dull patina and, depending on the local environment
and on the materials used in the installation, may develop some
surface oxidation (rust). This does not affect the performance of
the replace, and does not require any action to correct. If you
prefer keeping your replace front looking factory-fresh, clean it
as required with stainless steel cleaner.
When installation application includes highly acidic materials
such as acid wash or stone etching, do not remove the protective
PVC lm from the stainless steel until after this application is
complete. Once the lm has been removed, clean appliance
immediately with a stainless steel cleaner.
Please note that areas where the lm has been formed (corners,
hems, etc.) may require extra cleaning to remove lm residue.
Ensure that all protective lm has been removed from the
replace prior to burning.

Installing a New Gas Shut-Off Valve
Each appliance must have its own manual gas shut-off valve
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 replacement or relocation.
Test for leaks. Turn replace off. Compounds used on threaded
joints of gas piping shall be resistant to the action of liqueed
petroleum gases. The installer must check all gas connections
for leaks. Perform all leak tests with a leak test solution or soap
solution. Rinse off all solution once testing is complete. Perform a
pressure test on all unexposed connections.
Never use an exposed ame to check for leaks. Never
pressure test with appliance connected; control valve will
sustain damage. Disconnect the appliance from piping at the
control valve inlet and cap the pipe before pressure testing.
Install a gas valve and ground joint union in the gas line upstream
of the gas control to aid in servicing. The National Fuel Gas
Code requires installing a drip line near the gas inlet. The drip
line consists of a vertical length of capped pipe installed before
the gas inlet to collect condensation and foreign particles. See

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
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.

33858-1-0615Page 14
PLANNING INSTALLATION
In planning the installation for the replace, rst determine where
the unit will be installed, and then plan the gas supply piping.
The replace can be mounted on any of these surfaces:
1. A at combustible or non-combustible surface.
2. A raised platform made of combustible material.
3. Four corners of the replace so contact is made on all four
perimeter edges on the bottom of the unit.
(Example: Four masonry blocks - if allowed by local codes)
If the replace will be installed directly on carpeting, tile or other
combustible material other than wood ooring, your must rst
install a metal or wood panel extending the full width and depth
of the unit.
Decide what additional components to include in your installation.
Consult your dealer for assistance.
This replace is intended for installation on an outdoor patio or
in your yard. This replace shall be used only outdoors in a well
ventilated space and shall NOT be used in a building, garage, or
other enclosed area.
Install the replace in an area sheltered from direct wind, which
may cause erratic ames and main burner outage. Erratic ames
could also cause soot on logs, walls or ceiling. Flame outages
and sooting are nuisances but pose no safety issues.
Typical installation may include covered patio, screened porch,
gazebo or an outside wall of a house.
• Minimum porch area – 96 sq ft
• Minimum ceiling height – 84 inches
Installation in partial enclosures must conform to one of the
following conditions:
• With walls on all sides, but with no overhead cover. See
Figure 10.
FIREPLACE
Figure 10
• Within a partial enclosure with an overhead cover and no
more than two side walls. These side walls may be parallel,
as in a breezeway or at right angles to each side. See
Figure 11.
FIREPLACE
Figure 11
• If the replace is installed within a partial enclosure – such
as a porch, cabana, or pool-side bar – 30% or more of
the perimeter of the structure must remain permanently
open. The openings cannot be screened or have operable
windows/shutters. See Figure 12.

Finishing
All joints (top, bottom and sides), where the wall or decorative
facing material meets the replace surround should be sealed
with a 300°F minimum sealant material.
NOTICE: When installation application includes highly acidic
materials such as acid wash or stone etching, protect replace
nish with plastic stretch lm. Once the lm has been removed
clean appliance immediately with a stainless steel cleaner.
Please note that areas where the lm has been formed (corners,
hems, etc.) may require extra cleaning to remove lm residue.
Ensure that all protective lm has been removed from the
replace prior to burning.
Cleaning Instructions at Installation
This appliance is built using mostly high-grade stainless steel to
resist rust-through. In outdoor applications, all stainless steel will
develop a dull patina and, depending on the local environment
and on the materials used in the installation, may develop some
surface oxidation. This does not affect the performance of the
replace, and does not require any corrective action. If you prefer
keeping your replace front looking factory-fresh, clean it with
stainless steel cleaner.
FIREPLACE INSTALLATION INSTRUCTIONS
Install the Hood
Failure to install the furnished hood (or optional extension hood)
before the replace is used may create a re hazard.
1. Loosen the two screws (A) holding replace top to face panel,
then slide the hood ange between the replace top and face
panel and re-tighten the screws. See Figure 17.
2. Install one screw at each end of the hood as shown (B). See
Figure 17.

GAS LINE CONNECTION
The gas line must be installed by a qualied service person
in accordance with all building codes. The Commonwealth of
Massachusetts requires that a exible appliance connector
cannot exceed 3 feet.
A ex-line and shut-off valve have been provided. The gas shut-
off valve must be located outside of the unit in an accessible
area.
Check the rating plate on the replace (on a chain by the gas
valve) to ensure it shows the correct gas type. If the gas listed on
the rating plate does not match the gas supply to the home, do
not connect the replace. Contact your dealer for proper model.
Use an external regulator for all LP replaces to reduce the
supply tank pressure to a maximum of 13 inches w.c. This is in
addition to the regulator tted to the replace.
WARNING
Connection directly to an unregulated LP supply can cause an
explosion.

Pilot Flame Pattern
Figure 18 shows a correct pilot ame pattern. The correct ame
will be blue and will extend beyond the thermopile. The ame will
surround the thermopile just below the tip. A slight yellow ame
may occur where the pilot ame and main burner ame meet.
After prolonged use, the replace’s pilot burner may require
cleaning to maintain the proper ame. Clean with canned air. Let
pilot sit to dry.
To Remove Pilot Orice
1. Disconnect the pilot supply line at the pilot burner.
2. Remove pilot orice from pilot burner. It may be necessary to
tap on pilot burner in order to remove the pilot orice.
System Check
A millivolt meter set to the 0-1000 mV range is required to check
the system. Millivolt (mV) readings should be:
• Across the thermopile terminals, 400-450 mV with
thermostat OFF.
• Across the thermopile terminals, 150-250 mV with
thermostat ON.
• Across the optional switch wires at the valve, less than 30
mV with optional switch ON.
• Across the optional switch wires at the optional switch,
less than 5 mV with optional switch ON. Strong winds,
dirty pilot and low pressure will reduce readings.
