Some people cannot smell well. Some people cannot smell
the odor of the chemical stench put into the gas. You must
findoutifyoucansmelltheodorantinpropane. Smokingcan
decrease your ability to smell. Being around an odor for a time
can affect your sensitivity or ability to detect that odor. Some-
times other odors in the area mask the gas odor. People may not
smell the gas odor or their minds are on something else. Think-
ing 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,themovementofthegasthroughsoilcanfiltertheodorant.
Odorants in LP-Gas also are subject to oxidation. This fading

whentheremaynotbeaminutetolose,everyone'ssafetywill
depend on knowing exactly what to do. If, after reading the
followinginformation, youfeel youstill needmore informa-
tion, please contact your gas supplier.
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. Youmaynotknowallthefollowingsafetyprecau-
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
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-Gasmaystratifyinaclosedarea,andtheodorintensitycould
varyat differentlevels. Since itis heavier thanair, theremay 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.
•LearntorecognizetheodorofLP-gas. YourlocalLP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to find out what the propane odor smells like. If you suspect
thatyourLP-Gashas a weakorabnormalodor,callyourLP-
Gas Dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. Ifyouarequalified,consciouslythinkabouttheodor
ofLP-Gas priortoand whilelightingpilot lights orperform-
ing 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 filled and allowed
to set too long before refilling. Cylinders and tanks which
have been out of service for a time may develop internal rust
whichwill causeodor fade. If suchconditions aresuspected
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. Aperiodic snifftest oftheLP-gas isa goodsafety
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
sameimmediateactionrecommendedabovefortheoccasion
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 immedi-
ately. Ifthecontainervalveislefton,thecontainermaydraw
in some air through openings such as pilot light orifices. 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
turningitoffatthecontainerbeforeitgoescompletelyempty
or having it refilled before it is completely empty.
SAFETY INFORMATION FOR USERS OF LP-GAS
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Geteveryoneoutofthebuilding,vehicle,trailer,orarea. 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
firefighters declare them to be safe.
• Useyourneighbor'sphoneandcallatrainedLP-Gasservice
person and the fire 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 firefighters 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.
SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
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!

Clearances
1. In selecting a location for installation, it is necessary to provide
adequateaccessibilityclearancesforservicingandproperinstallation.
2. Although certified for 0 clearance to the floor , the unit is held in
place by a wall bracket. Enough clearance [2" (51mm) suggested]
to allow changing or adding floor covering is recommended. Other
clearances to combustible construction:
Sides 1" (25mm) and 12" (305mm) from the top.
3. Note the position of the vent relative to the center of the unit. The
DV-210 has the vent in the center. The DV-215 vent is 2" (51mm)
off center to the right.
4. The minimum distance from the center of the outside vent to the
nearest outside corner or obstruction is 16" (406mm).
5. TheDV-210/DV-215minimumwalldepthis41/2"(114mm)and
maximum wall depth is 13" (330mm). The use of tubes not
supplied by the manufacturer result in unsatisfactory
performance.

feet (1.8m) distance will reduce the chance of gas entering the
vent cap.
Locating Wall Opening
Thefurnace istobelocatedon anoutsidewall. Locatewallstuds sothat
wall opening will be located between wall studs. One wall stud can be
used for attachment of inside wall plate. The wall opening required as
shownin Figure1is aminimumdiameter of61/4 (159mm)inches. The
inside wall plate and the outside wall plate are large enough to permit a
wall opening diameter of 8 inches (203mm).
A template is provided in furnace carton for positioning furnace on the
wall. Also, refer to Figure 1 for positioning the furnace on wall and for
locating gas line connection.
Locating Gas Supply
The gas line can enter the unit either through the floor or outside wall.
The gas line opening should be made at this time. Location of the
opening will be determined by the position of floor joists and the valve
and union used for servicing.

5. Reassembly and resealing vent-air intake system is completed.
Installing a Vent Near a Window Ledge,
Other Type of Projection or on Vinyl Siding
Direct vent furnaces are designed to be installed on a uniform outside
wall. When the wind comes from any angle (up, down or from either
side), it must hit the vent cap equally over both the air inlet and the flue
outlet portions of the vent. Any wall projection, such as a door or
window casing, which disturbs the wind on one side of the air inlet
section will result in back pressure on the flue section smothering the
flame and eventual pilot outage.
When the vent cap is to be installed on vinyl siding or it appears that a
projection within 6" (152mm) of any side of the air inlet section could
shieldtheairinletsection,theentireventshouldbesupportedawayfrom
thewallatleastthedistanceoftheprojection. 2"x 4"(51mm x102mm)
framing whose outside dimensions match the overall dimensions of the
mountingplateisrecommended. The2"x4"(51mmx102mm)framing
protects vinyl siding from possible warpage or discoloration. All joints
can then be sealed and painted. The wall depth plus the additional depth
of the 2" x 4" (51mm x 102mm) framing should not exceed a total depth
of 13" (330mm) for DV-210/DV-215. (See Figure 3)
Figure 3a
Vinyl siding vent kit, DV-822, is available from Empire Comfort
Systems, Inc. The depth is 3" (76mm), which enables the vent cap to be
extendedawayfromvinylsidingorprojections. Thewalldepthplusthe
additional3"(76mm)depthofthevinylsidingventcapextensionshould
not exceed a total depth of 13" (330mm) for DV-210/DV-215. (See

Warning: When vinyl siding vent kit, DV-822 or 2" x 4"
(51mm x 102mm) framing is added to an existing installation
(furnace is installed) do not attempt to add sections of pipe to
theflueoutlettubeorairinlettube. Anairtightsealisrequired
for both tubes. Refer to Parts List, page 9 to order tubes.
Installation on Rugs and Tile
If this appliance is to be installed directly on carpeting, tile, or other
combustible material, other than wood flooring, the appliance shall be
installed on a metal or wood panel extending the full width and depth of
the appliance.
The base referred to above does not mean the fire-proof base as used on
woodstoves. The protectionisprimarilyforrugs thatmay beextremely
thick and light-color tile that may discolor.
Gas Supply
Check all local codes for requirements, especially for the size and type
of gas supply line required. On Natural gas lines less than 15' (4.6m)
long, use 1/2" (13mm) pipe; on longer runs, use 3/4" (19mm) iron pipe
or equal. On LP gas lines please consult LP gas supplier.
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.

Piezo Pilot Ignitor Instructions
Depressingtheredbuttoncompletelycausesasparktooccuratthepilot.
This is a substitute for a match which requires opening the pilot hole
cover.
To light the pilot, it is important that the electrode be 1/8" (3mm) from
the thermopile. The spark must occur at the point the burner flame hits
thethermopile. Theendoftheelectrodewillberedhotwiththepiloton.
On a new installation with air in the gas line, it is suggested that a match
be used. The match will light the pilot faster than the piezo under this
condition.
Steps in Removing Main Burner, Orifice and Valve
1. Disconnect the thermopile and pilot supply line at the pilot burner.
2. Remove the burner compartment cover 5/16" (8mm) socket
suggested.
3. Remove screw holding left side of burner and lift out.
4. Main burner orifice is now accessible. Use 1/2" (13mm) box end
wrench to remove and apply non-hardening pipe dope sparingly to
orifice threads when replaced.
5. To remove the entire gas valve the nut holding the orifice fitting to
the chamber must be removed and the gas supply to the valve
disconnected. Afterthis,thevalveandorificeelbowcanberemoved
as a unit.
Cleaning The Pilot Burner
Cleaning of the pilot may be an annual necessity due to spiders. After
removing the supply tubing and orifice, use a pipe cleaner or wire to
clean the entire internal part of the pilot.
Cleaning the Combustion Chamber and Main Burner
Whenthe mainburner andvent capare removed,all internalareas ofthe
combustion chamber are accessible for cleaning with a vacuum hose.
The main burner may be cleaned by forcing water into the ports and the
throatofthe burner. The burnershouldbeblown dry orheatedto dry all
water out before reinstalling.
Proper Pilot Flame (Figure 5)
The pilot flame is blue and goes toward the main burner and thermopile
horizontally. Aslight yellowtip onthe flameis normal. Thepilotflame

Never use an exposed flame 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!
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 line be installed near the gas inlet.
Thisshould consistof avertical lengthof pipetee connectedinto thegas
line that is capped on the bottom in which condensation and foreign

Than All-Metal Construction
Theabove connectors maybe used ifacceptable by theauthority having
jurisdiction.
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.
plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to the
appliance.
2. Theapplianceandits individual shutoff valvemustbedisconnected

less than 1/2 psig (3.5 kPa).
Attention! Ifoneoftheaboveproceduresresultsinpressuresinexcess
of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will result
in a hazardous condition.
Checking Manifold Pressure
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 4.0" w.c. (.996kPa) at the valve outlet with the inlet
pressure to the valve from a minimum of 6.0" w.c. (1.494kPa) for the
3" (76mm) MIN.

circuits.
Exterior Wall — The thermostat may be mounted on an exterior wall
abovetheheaterifitislocatedinthesamestudspaceastheventtubesand
is a minimum of 6" (152mm) above the heater.
Interior Wall — The thermostat should be installed on an inside wall
away from the unit but in the same room.
Note: Use 16 gauge wire to prevent excessive loss of millivolts.
Proper operation depends on a good pilot flame. The flame must cover
thetopofthethermopile. Cleaningof the pilot orifice and burner may be
required due to spiders.
System Check
A millivolt meter is required to check the system. The millivolt readings
should be:
• Across the thermopile terminals, 400-450 millivolts with thermostat
OFF.
• Across the thermopile terminals, 150-250 milllivolts with thermostat
ON.
• Across the thermostat wires at the valve, less than 30 millivolts with
thermostat ON.
• Across the thermostat wires at the thermostat, less than 5 millivolts
with thermostat ON. (Strong winds, dirty pilot and low pressure will
reduce readings.)
