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, use your phone.
Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area. Do
that IMMEDIATELY.
• 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 reghters
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 building, vehicle, trailer, or area.
• Finally, let the service man and reghters 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 it 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 stratify 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 qualied, do not light pilot lights, perform service,
or make adjustments to appliances on the LP-Gas system. If
you are qualied, consciously think about the odor of LP-Gas
prior to and while lighting pilot lights or performing service or
making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, 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 relling. 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. Then take the same
immediate action recommended above 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 such as pilot light orices. 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 relled before it is
completely empty.

Television Considerations
Installing a television above a replace has become a desirable
feature; however, the following information should be considered.
All replaces, whether decorative or heater rated create heat.
Most television manufacturers recommend not placing a television
near a heat source. Because there is a large variety of television
manufactures, styles and sizes, it is impractical to test every potential
installation. If you choose to install a television above or near your
replace, understand that Empire Comfort Systems accepts no
responsibility for this decision and any injury or damage due to this
application is the sole responsibility of the owner. Additionally, it is
highly recommended to turn off the replace and let it cool down
before servicing or using the operational buttons located on the
television. In all cases, the television manufacturer’s instructions
and warnings should be followed.
Combustible Material
No greeting cards, stockings or ornamentation of any type should
be placed on or attached to the replace. The ow of heat can ignite
combustibles. See Figure 3.

Notice: Never use plastic pipe. Check to conrm whether your local
codes allow copper tubing or galvanized.
Notice: Since some municipalities have additional local codes, it
is always best to consult your local authority and installation code.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings.
— ANS Z21.45 Assembled Flexible Appliance Connectors of Other
Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The state of Massachusetts requires that a
exible appliance connector cannot exceed three feet in length.

Installing a New Main Gas Cock
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 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.
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
appliance connected; control valve will sustain damage!
Notice: The gas controls are equipped with a captured screw type
pressure test point, therefore it is not necessary to provide a 1/8"
test point up stream of the control.
When using copper or ex connector use only approved ttings.
The appliance and it’s 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 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 (3.5kPa).
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" w.c. (.871kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 5.0" w.c.
(1.245kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa). Propane gas models will have a manifold
pressure approximately 10.0" w.c. (2.49kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 10.8" w.c.
(2.68kPa) for the purpose of input adjustment to a maximum of
14.0" w.c. (3.484kPa).

Finishing
Finish the walls with the material of your choice. Figure 4 on page 8
shows the minimum vertical and corresponding maximum horizontal
dimensions of mantels or other combustible projections above the
top front edge of the replace.
Only non-combustible materials may be used to cover the metal
replace face. See Figure 3, Page 8.
WARNING
If the joints between the nished wall and the replace surround
(top and sides) are sealed, a 300°F minimum sealant material
must be used. These joints are not required to be sealed. Only
non-combustible material (using 300°F minimum adhesive if
needed), can be applied as facing to the replace surround.
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.
The appliance can be mounted on any of the following surfaces:
1. A at, hard combustible surface.
2. A raised wooden platform.
3. Six supports. (Example: Six concrete masonry blocks.) These
supports must be positioned so they contact all four perimeter
edges on the bottom of the unit and under the center leg supports,
if allowed by code.

VENTING FIREPLACE
To Use the Vent Graph
1. Determine the height of the center of the horizontal vent pipe. Using this dimension on the Sidewall Vent Graph, locate the point it
intersects with the slanted graph line.
2. From the point of this intersection, draw a vertical line to the bottom of the graph.
3. Select the indicated dimension, and position the unit in accordance with same.
Figure 22 (DVLT36 and DVTT36)
Acceptable vertical and horizontal vent run.
(40' maximum vertical and 20' maximum horizontal)
Unacceptable vertical and horizontal vent run.
EXAMPLE A:
If the vertical dimension from the top of the unit is 35', the horizontal
run to the outer wall ange must not exceed 5'.
EXAMPLE B:
DV(LT,TT)36: If the vertical dimension from the top of the unit is
4.5', the horizontal run to the outer wall ange must not exceed 11'.
DV(LT,TT)42: If the vertical dimension from the top of the unit is
5', the horizontal run to the outer wall ange must not exceed 11' .
31259-3-0114 Page 15
Figure 23 (DVLT42 and DVTT42)
Special Note: For each 45 degree elbow installed in the horizontal
run, the length of the horizontal run MUST be reduced by 18" (45cm).
This does not apply if the 45 degree elbows are installed on the
vertical part of the vent system. Reduce 3' for every 90° elbow.
Example: According to the chart the maximum horizontal vent length
is 20' and if two 45 degree elbows are required in the horizontal
vent it must be reduced to 17'.
The maximum number of 45 degree elbows permitted per side wall
installation is two (2). These elbows can be installed in either the
vertical or horizontal run.
NOTE: The rst elbow does not get counted.

Below Grade Installation
When it is not possible to meet the required vent terminal clearances
of 12" (305mm) above grade level, a snorkel kit is recommended.
It allows installation depth down to 7" (178mm) below grade level.
The 7" (178mm) is measured from the center of the horizontal vent
pipe as it penetrates through the wall.
Ensure the sidewall venting clearances are observed. If venting
system is installed below ground, we recommend a window
well with adequate and proper drainage to be installed around
the termination area.
