SAFETY INFORMATION FOR USERS OF LP-GAS
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
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
firefighters declare them to be safe.
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 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
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.
• 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.
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 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
Page 4 13119-6-0107
-
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.

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
all precautions required and has complied with all the requirements of the
authority having jurisdiction.
State of Massachusetts: The installation must be made by a licensed
plumber or gas fitter in the Commonwealth of Massachusetts.

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.

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
Figure 1
Consult the current National Fuel Gas Code, ANSI Z223.1 CAN/
CGA-B149 (.1 or .2) installation code.
13119-6-0107 Page 7
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
CLEARANCES
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”.
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.
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.
