IMPORTANT SAFETY INFORMATION
VENT KIT INFORMATION

Page 4 13119-6-0107
Some people cannot smell well. Some people cannot smell the
odor of the chemical put into the gas. You must find 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 filter 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.
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau-
tions 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.
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a “Scratch and Sniff” pamphlet. Use it
to find 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 qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the odor
of LP-Gas prior to and while lighting pilot lights or perform-
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
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 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 turning it off
at the container before it goes completely empty or having
it refilled before it is completely empty.
• 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
firefighters declare them to be safe.
• Use your neighbor’s phone and call a trained LP-Gas service
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!

Standard/CSA Standard Z21.86 and CSA 2.32 by the Canadian Standards
Association, as a fan type direct vent wall furnace to be installed according
to these instructions.
Any alteration of the original design, installed other than as shown in
these instructions or use with a type of gas not shown on the rating plate
is the responsibility of the person and company making the change.
Important
All correspondence should refer to complete Model No., Serial No. and
type of gas.
Notice: During initial firing of this unit, its paint will bake out and smoke
will occur. To prevent triggering of smoke alarms, ventilate the room in
which the unit is installed.
Installation on Rugs and Tile
If this appliance is 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
wood stoves. The protection is for rugs that are extremely thick and light
colored tile.
Installation in Residential Garages
Gas utilization equipment in residential garages shall be installed so that
all burners and burner ignition devices are located not less than 18” above
the floor.
Such equipment shall be located, or protected, so it is not subject to physical
damage by a moving vehicle.
Qualified Installing Agency
Installation and replacement of gas piping, gas utilization equipment or
accessories and repair and servicing of equipment shall be performed
only by a qualified agency. The term “qualified agency” means any
individual, firm, corporation or company which either in person or through
a representative is engaged in and is responsible for (a) the installation
or replacement of gas piping or (b) the connection, installation, repair or
servicing of equipment, who is experienced in such work, familiar with

codes, with the National Fuel Gas Code ANSI Z223.1/NFPA 54* Natural
Gas and Propane Installation Code, CSA B149.1.
*Available from the American National Standards Institute, Inc., 11 West
42nd St., New York, N.Y. 10036.
High Altitudes
For altitudes/elevations above 2,000 feet, input ratings should be reduced
at the rate of 4 percent for each 1,000 feet above sea level. For Canadian
high altitude applications, this appliance is suitable for installation at
elevations between 0 feet and 4,500 feet without change.
Piezo Pilot Ignitor Instructions
Depressing the red button completely causes a spark to occur at the pilot. 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” from the
thermocouple. The spark must occur at the point the burner flame hits the
thermocouple. The end of the electrode will be red hot with the pilot on.
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.

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.
Note: Never use plastic pipe. Check to confirm whether your local
codes allow copper tubing or galvanized.
Note: 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 flexible
appliance connector cannot exceed three feet in length.
Figure 1
Consult the current National Fuel Gas Code, ANSI Z223.1 CAN/
CGA-B149 (.1 or .2) installation code.
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 liquefied 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 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. 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.
Figure 2
Method of Installing a Tee Fitting Sediment Trap
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8” N.P.T.
plugged tapping, accessible for test gauge connection, must be
placed immediately upstream of the gas supply connection to
the appliance.
2. The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2
psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff 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 above procedures results in pressures in
excess 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) for DVC-35T and
3.5” w.c. (.871kPa) for DVC-35IPT 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 7.0” w.c.
(1.743kPa). 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 11.0” w.c. (2.739kPa)
for the purpose of input adjustment to a maximum of 13.0” w.c.
(3.237kPa).
A 1/8” N.P.T. plugged tapping, accessible for test gauge connection,
is located on the outlet side of the gas control.
The built-in regulator comes on at approximately 1/4th pressure
and full on in 10 seconds.
Clearances
1. In selecting a location for installation, it is necessary to provide
adequate accessibility clearances for servicing and proper
installation. A front clearance of 36” is recommended. Do not
block outlet or inlet air openings on the front grill.
2. The DV4T-59-1, 5” to 9” wall depth is the standard vent kit
provided with the DVC-35T or DVC-35IPT. See Accessories
Page 6 to order vent kits for wall depths of 8” to 12” or 12”
to 19”. The use of tubes not supplied by the manufacturer
results in unsatisfactory performance.
3. The DVC-35T and DVC-35IPT can be attached to the wall or
recessed into the wall up to 9 1/2” in depth but the minimum
5” vent/air intake system wall depth must be maintained.
Example: If furnace is recessed into the wall at a depth of
9 1/2”, the minimum wall depth behind the furnace must be
5”.
4. The wall in which the furnace is recessed has (0) zero clearance
to the furnace sides and top.
5. When using side discharge registers, SOR-1 or SOK-1, the
furnace cannot be recessed into the wall.
6. Clearance to sidewall or combustible material is 4”.
7. Ceiling clearance is 4”.
8. Floor and rear wall clearance is (0) zero inches.
9. Clearance of 18” is required to sidewall or combustible material
when flush mounted SOR-1, side outlet register is used.
10. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 12”.
Figure 4
The vent terminal of this direct vent appliance shall be located at
least 9” from any opening through which flue gases could enter a
building. The bottom of the vent terminal and the air intake shall
be located at least 12” above grade. See vent location, Figure 4.
WARNING: The nearest point of the vent cap should be
a minimum horizontal distant of six (6) feet from any
pressure regulator. In case of regulator malfunction, the
six (6) feet distance will reduce the chance of gas entering
the vent cap.
CLEARANCES

13119-6-0107 Page 9

Attaching Furnace to Wall
Place collar on four inch flue tube against outlet box. Align clearance
holes on collar with screw holes in outlet box. Attach four inch flue
tube to outlet box with four (4) 10 x 1/2” screws.
Attention: Do not overtighten screws because outlet box must be
able to move as flue tube expands and contracts.
Place collar on six inch air tube against air drop. Align clearance
holes on collar with screw holes in air drop. Attach six inch air tube
to air drop with eight (8) 10 x 1/2” screws.
Refer to Figure 5 for the location of the 7 1/2” diameter wall open-
ing for the furnace. After the wall opening has been located and
cut, position flue outlet on furnace in center of wall opening. Insert
tubes through wall opening. When attaching furnace to the wall
remove that portion of baseboard and molding on the wall which is
behind the furnace. Attach furnace to wall, at the outer casing top,
with two (2) plastic expansion anchors provided and to floor, at the
outer casing bottom, with two (2) 10 x 1 1/2” screws provided.

13119-6-0107 Page 11
Installing a Vent Near a Window Ledge,
Other Type of Projection or on Siding (vinyl, aluminum, etc.)
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 siding or it appears that a
projection within 6” of any side of the air inlet section could shield
the air inlet section, the entire vent should be supported away from
the wall at least the distance of the projection. 2” x 4” framing
whose outside dimensions match the overall dimensions of the
mounting plate is recommended. The 2” x 4” framing protects
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” framing should not exceed a total depth of 14” for
DVC-35T. (See Figure 10)
Vinyl siding vent kit, DV-822, is available from Empire Comfort
Systems, Inc. The depth is 3”, which enables the vent cap to be
extended away from siding or projections. The wall depth plus the
additional 3” depth of the vinyl siding vent cap extension should
not exceed a total depth of 19” for DVC-35T. (See Figure 11)
Warning: When vinyl siding vent kit, DV-822 or 2” x 4”
framing is added to an existing installation (furnace is
installed) do not attempt to add sections of pipe to the flue
outlet tube or air inlet tube. An air tight seal is required for
both tubes. Refer to Parts List, page 16 to order tubes.
Figure 10 Figure 11
Installing Vent Assembly
Attention: DO NOT attempt to cut vent tubes. When you order
appropriate vent kit for measured wall depth the vent tubes will
fit together.
1. Place provided caulking beneath the collar of the outside
mounting plate. Use additional caulking to correct uneven wall
surface, such as clapboard.
2. Insert six inch air tube on outside mounting plate INTO six
inch air tube attached to air drop. Place four inch flue tube
on vent cap OVER four inch flue tube attached to outlet box.
Position the outside mounting plate so that six inch air tube
has a slight downward slope to the outside. The downward
slope is necessary to prevent the entry of rainwater. Attach
outside mounting plate to exterior wall with four (4) 10 x 1 1/2”
screws.
3. Installation is completed.
Reassembly And Resealing Vent-Air Intake System
When vent-air intake system is removed for servicing the furnace,
the following steps will assure proper reassembly and resealing of
the vent-air intake assembly.
1. Remove old caulking beneath the collar of the outside mounting
plate. Apply new caulking beneath the collar of the outside
mounting plate. Use additional caulking to correct uneven wall
surface, such as clapboard.
2. Insert six inch air tube on outside mounting plate INTO six
inch air tube attached to air drop. Position the outside mounting
plate so that six inch air tube has a slight downward slope to
the outside. The downward slope is necessary to prevent the
entry of rainwater. Attach outside mounting plate to exterior
wall with four (4) 10 x 1 1/2” screws.
3. Place four inch flue tube on vent cap OVER four inch flue tube
attached to outlet box. Attach vent cap to outside mounting plate
with three (3) 10 x 1/2” screws.
4. Reassembly and resealing vent-air intake system is
completed.

The correct pilot flame (Figure 12) will be blue, extending past
the thermocouple. The flame will surround the thermocouple just
below the tip.
Natural gas pilots require adjusting when the inlet gas pressure is
above 5” w.c. (1.245kPa). Remove the pilot cover screw on the
control valve (Figure 3), and turn the adjustment screw clockwise
to reduce flame. Replace pilot cover screw to eliminate gas leaking
at that control valve opening.
LP gas (propane) will not require adjustment.
After use, cleaning may be required for the proper flame.
IP-Model Pilot
This heater is using a Honeywell “Smart Valve” system for
intermittent pilot ignition.
On a call for heat by the thermostat this control turns on a 24 volt
mini hot surface ignitor which lights a pilot that in turn lights the
main burner. The gas valve used in this system is a step opening
which opens at a lower pressure for ignition and then steps to a
full inlet pressure of 4” pressure on Natural gas and 10” pressure
on LP gas.
Pilot Flame Adjustment
The pilot flame should envelop 3/8 to 1/2 inch (10 to 13mm) of the
tip of the flame rod. See Figure 12.
To adjust:
1. Remove the pilot adjustment cover screw.
2. Turn the inner adjustment screw clockwise to decrease
or counterclockwise to increase pilot flame. Pilot ad-
justment is shipped at full flow rate. Turn the inner adjustment
screw clockwise if the inlet pressure is too high.
3. Replace the cover screw after the adjustment to prevent gas
leakage.

The appliance, when installed, must be electrically grounded in ac-
cordance with local codes or, in the absence of local codes, with the
National Electrical Code, ANSI/NFPA 70 or Canadian Electrical
Code, CSA C22.1, if an external electrical source is utilized. This
appliance is equipped with a three-prong [grounding] plug for
your protection against shock hazard and should be plugged
directly into a properly grounded three-prong receptacle. Do
not cut or remove the grounding prong from this plug. For an
ungrounded receptacle, an adapter, which has two prongs and a
wire for grounding, can be purchased, plugged into the ungrounded
receptacle and its wire connected to the receptacle mounting screw.
With this wire completing the ground, the appliance cord plug can
be plugged into the adapter and be electrically grounded. A 7/8”
hole is provided in the junction box for use with a conduit connector
if local codes require this type of protection.
Thermostat Installation
The thermostat should be installed in the same room as the furnace
4’ to 5’ above the floor and away from another heat source (cooking
stove, hot water heater, etc.) including walls and doorways with
a heat source in an adjoining room. Do Not Install Thermostat
on Outside Wall.
CAUTION: Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after servicing.
Figure 14
The correct flame will be a short, blue inner flame with a much
larger, light blue, outer flame. The burner does not have a primary
air adjustment. The flame will be correct if the factory-set pressure
and orifice opening are used. After the furnace has been operating,
the burner ports may be blocked by foreign matter carried in by
combustion air. Therefore, cleaning of the burner may be needed
for proper flame.
To clean burner port disconnect the gas supply to the valve, and
remove the screws fastening the burner door. After removing the
burner door from the burner box, remove each main burner. Pilot
mounting bracket will need to be unscrewed and moved out of the
way to remove all burners. Burners can be blown out using com-
pressed air or by blowing through them. Be sure there is no lint
or foreign debris blocking the burner ports. Reassemble using the
same screws earlier removed and locate pilot in the same position
as before and noted above. Figure 13

GENERAL: All furnaces have been fire-tested to check for proper
operation. This includes, main burner flame, pilot flame, fan
operation, fan control, limit control and automatic valve operation.
If the furnace fails to function on initial installation, it is advisable
to re-check the following:
1. 115 volts to the junction box.
2. Inlet gas pressure.
3. The 24 volt system.
4. Type of gas being used and that shown on the rating label.
The Service Department at Empire Comfort Systems, Inc. may
be contacted to assist in servicing furnace or a call a qualified
serviceman.
Standing Pilot Model
Servicing the Pilot and Main Burners, Pilot Orifice,
Thermocouple, and Main Burner Orifices: Disconnect the gas
supply at the inlet to the control valve. Then remove the burner
door to gain access to the above listed components.
Spark Igniter Does Not Light Pilot: With air in the gas line, such
as when the furnace is first installed or was off all summer, the
pilot flame may be too lean to ignite on the first few trials. Turn
the control valve knob to pilot position and depress the red reset
button. Holding the button down continually to bleed the line;
1. Use lighter rod to light pilot with a match.
2. Use the piezo ignitor at 30 second intervals until it lights.
If Electrode Does Not Produce Spark:
1. Check wire connections.
2. Check gap for pilot burner to the electrode tip. Should be
between 1/8” and 3/16”. Electrode wire and tip must be
more than 1/4” away from all other metal components.
If Pilot Does Not Light By Any Means:
1. Check valve knob for being in the “Pilot” position.
2. Check pilot adjustment for being full open (counterclockwise
to open).
3. If gas is available in the supply tubing, the pilot orifice and/or
pilot burner is probably restricted by a spider web. Clean
pilot assembly and relight.
If Pilot Does Not Remain On After Releasing Knob:
1. Follow instructions and hold button down longer and
harder.
2. Determine if pilot flame extends past thermocouple; if not,
adjust input or clean pilot burner.
3. Replace thermocouple if millivolts read less than 15
millivolts.
Pilot Outage During Normal Operation:
1. Check air inlet tube for a good fit.
2. Check burner door and pilot hole cover for tight seal.
3. Check input by manifold pressure gauge or gas meter.
Main Gas Valve Does Not Open When Thermostat Is Turned
To On:
1. Check for 24 volts to valve by removing one wire and
touching to the SAME TERMINAL it was on. Terminal
should have a light spark. DO NOT SHORT ACROSS
TERMINALS, AS IT WILL BURN OUT THE WALL
THERMOSTAT.
2. Thermostat wires at the wall may be shorted, so check for
a faulty thermostat.
3. To check for line voltage to furnace, remove front panel and
short across two-terminal fan control to allow fan to operate.
(Figure 15)
Cleaning Combustion (Exchanger) Assembly
A QUALIFIED SERVICE PERSON should remove the combustion
(exchanger) assembly and flue baffles. Apply air pressure to the
inside of the combustion (exchanger) assembly and flue baffles in
order to clear all passageways.
Oiling the Motor
The fan motor should be cleaned and oiled once each heating
season. Oil holes are located on the top at each end of the motor.
Use a few drops of #10 motor oil. To clean the motor, blow air
through its ventilation openings with a vacuum cleaner or low
pressure air source.
