INSTALLATION MANUAL
FOR MODELS
NT-12S • NT-16S • NT20S
The design of these furnaces has been certified for installation in recreational vehicles only. In order for these furnaces to operatein conformity
with generally accepted safety regulations, the installation instructions outlined in this book must be followed. Failure to comply with the
installation instructions will void any responsibility of Suburban Manufacturing Company. Your furnace was inspected before it left the factory. If
any parts are found to be damaged do not install the furnace. Any damages should be reported to the transportation company immediately and
the appropriate claims filed.
WARNING! Improper installation, adjustment, alteration, service or maintenance can
cause property damage, personal injury or loss of life. Refer to the installation
instructions and/or owners manual provided withthis appliance. Installation and service
must be performed by a qualified installer, service agency or the gas supplier.
INSTALLATION INSTRUCTIONS
WARNING!Installation of this appliance must be made in accordance with
the written instructions provided in this manual. No agent,representative
or employee of Suburban or other person has the authority to change,
modify or waive any provision of the instructions contained in this
manual.
CAUTION: If possible, do not install the furnace to where the vent can be
covered or obstructed when any door on the trailer is opened. If this is not
possible, then the travel of the door must be restricted in order to provide
a 6" minimum clearance between the furnace vent and any door whenever
the door is open.
NOTE: The exhaust temperature of this furnace could discolor or warp some
materials. You should verify that the material used on the coach door, panel, or
cover will not discolor or warp from the exhaust temperature whenever any door,
panel, or cover is in the open position.
CAUTION: Due to the differences in vinyl siding, this appliance should not
be installed onvinylsiding withoutfirstconsulting with the manufacturer of
the siding or cutting the siding away from the area around the appliance
vent.
CAUTION: In any installation in which the vent of this appliance can be
covered due to the construction of the RV or some specialfeature ofthe RV
such as slide out, pop-up, etc. always insure that the appliance cannot be
operated by setting the thermostat to the positive “OFF” position and
shutting off all electrical and gas supply to the appliance. Never operate
furnace with vent covered.
These furnaces must be installed and vented as described in this manualso that
the negative pressure created by the air circulating (return air) fan cannot affect
the combustion air intake or venting of any other appliance. It is imperative that
the products of combustion be properly vented to the atmosphere and that all
combustion air supplied to burner be drawn from the outside atmosphere. (See
“Installing Vent Assembly”.)
IMPORTANT: If this furnace is to be connected to a common duct system also
serving a cooling unit, a manual or automatic damper is required to prevent any
cold conditioned air from circulating back into the furnace. Cold air passing over
the furnace combustion chamber during the operation of the cooling unit can result
in the formation of condensation inside the furnace combustion chamber. This
condensation may promote corrosion and premature failure of the combustion
chamber.
NOTE: These furnaces shall be installed so the electrical components are
protected from water.
These furnaces will accommodate an installation depth from 23 3/8" minimum
(with standard vent tubes), to 30 1/8" maximum (with optional intake extension
tubes). (See Figure 1.)
Please adhere strictly to the installation instructions to insure proper installation
and safe operation, as well as adequate clearances for accessibility.
These furnaces are certified for use with propane/LP gas only. Gas supply
pressure for purposes of input adjustment:
Gas Minimum Maximum
Propane/LP 11" W.C.* 13" W.C.
*Water column Return air
Return air must be from the living area of the coach.
NOTE: RV’s that have a wall of separation to a cargo area (Toy Box) to transport
internal combustion engine vehicles must not have return air opening from this
area.
An opening mustbe provided in the interior cabinetry ofthe coach directlyin front
of the furnace. The opening must allow for free, unobstructed removal of the
furnace. This opening may be used as a means of providing circulating return air
to the furnace. Other openings may be used as well. The minimum return air to
the furnace must total 55 square inches free area. It is important that sufficient
return air be providedto insure normal heating and operation of the furnace.Also,
adequate clearances must be maintained around the furnace cabinet so that the
unit will be accessible for servicing. Failure to provide minimum return air as well
as an adequate opening for furnace removal voids the warranty.
In the USA, the installation must conform withlocal building codes. In the absence
of local building codes, refer to the latest edition of:
1-Standard for Recreational Vehicles ANSI A-119.2/NFPA 501C.
2-National Fuel Code ANSI Z223.1.
The furnace mustbe electrically grounded in accordance withthe latestedition of
the National Electrical Code ANSI/NFPA No. 70. The installation of the furnace
shall be in accordance with any applicable local codes and regulations.
In Canada, the furnace must be installed in accordance with:
1-StandardCAN/CSA-Z240.6.2-M86ElectricalRequirementsforRecreational
Vehicles.
3-Standard CAN/CSA-Z240.4.2-M86 Installation Requirements for Propane
Appliances and Equipment in Recreational Vehicles.
4-CAN/CGA-B149 Installation Codes
5-Any applicable local codes and regulations.
TO INSTALL THE FURNACE
1. Locate the furnace near lengthwise center of the coach. Do not install the
furnace with the vent facing toward the forward end of the coach.
2. Select a location for installation out of the way of wires, pipes, etc. that might
interfere with installation. Adhere to the following minimum clearances from the
furnace cabinet to combustible construction.
NT-12 • NT-16
Front 3/8" Floor 0" NT-20S Front 1" Floor 0"
Sides 1" Top 1" Sides 1" Top 1"
Back 0" Back 0"
NOTE: Side and top clearances may be 0" for through the wall installations up to
a maximum of 2 1/2" wall thickness (See Figure 3.)
3. When an appliance is installed directlyon 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. If preferred, the
carpeting, tile or combustible materials, other than wood may be cut away the full
length and depth of the appliance plus the appliance minimum clearances to
combustibles.
4. Determine “X” dimension as shown in Figure 1 or 2 depending on model.
5. Determine “Y” dimension as shown in Figure 1 or 2.
6. If X-Y is less than 22 3/4"forModels NT-12 or NT-16,or 233/8"forModelNT-
20, then an opening 9 5/8" x 9 3/8" must be cut through the inner wall only. DO
NOT CUT THROUGH COACH SKIN. (See Figure 3.) Next, locate the center line
of the exhaust and intake tube. Cut two (2) 2 1/4" diameter holes through outer
skin as shown in Figure 5.
NOTE: Whenever the furnace cabinet is installed through the outside wall, the
return air louvers on the furnace cabinet must not be blocked. The maximum
projection of the furnace cabinet into the wall is 2 1/2". (See Figure 3.)
NOTE: Furnace cabinet approved for 0" clearance to combustible materials rear
2 1/2" of furnace cabinet.
7. If X-Y is 23 3/4" or greater for Model NT-12 or NT-16, or 23 3/8" or greater for
Model NT-20, two methods may be used to install the furnace. They are:
a. Cuta 4" x 7 1/2" opening through combustible wallas shown in Figure 4.DO
NOT CUT THROUGH TRAILER SKIN. Next,locate the centerline ofthe exhaust
and intake tube. Cut two (2) 2 1/4" diameter holes through trailer skin.
(See Figure 5.)
b. If you do not wish to cutthe 4" x 7 1/2"opening, locate the center line of the

2
exhaust and intake tube as shown in Figure 5. Next, cut two (2) 2 3/4" diameter
holes through trailer skin and also the combustible wall ofthe trailer as illustrated
in Figure 7. Care must be taken when locating the center line of the exhaustand
intake tube as well as when cutting the holes in order to assure a 3/8" clearance
around the exhaust and intake tubes to combustible materials.
8. Refer to the chartin Figure 1 or2 (depending on the furnace model) and select
the range for which the “X” dimension falls. The intake tube length directly to the
leftof the selected range is the length required. NOTE: The 7 3/4" length exhaust
tube assemblywillaccommodateallapprovedinstallation depths-only theintake
tube must be ordered when needed.Underno circumstances should the standard
3" intake tube be used when “X” dimension is greater than 25" for Model NT-12
or NT-16, or greater than 25 5/8" for Model NT-20.
9. Secure furnace to the floorusing the two holes provided in the frontarea ofthe
furnace cabinet. (See Figure 3 or 4.)
CONNECTING GAS SUPPLY
Connect the gas fitting (3/8" NPT to 3/8" Flare) to the furnace at the manifold
provided on the right side of the furnace (Figure 3 or 4). It will be necessary to
hold the flare fitting on the furnace manifold when connecting or loosening gas
line.
NOTE: Be sure all male joints have been treated with a sealing compound
resistant to the action of liquefied petroleum (LP) gas.
NOTE: The appliance must be disconnected from the gas supply piping system
during anypressure testing ofthatsystem attestpressure in excess of 1/2 PSIG.
The appliance must be isolated from the gas supply piping during any pressure
testing of the gas supply piping system at test pressure equal to, or less than 1/2
PSIG.
In order to maintain a check on gas supply pressure to the furnace, Suburban
advises the installer to provide a 1/8" NPT plug tap for test gauge connection
immediately upstream of the gas supply connection to the furnace.
After the furnace has been connected to the gas supply, all joints must be
checked for leaks.
WARNING! Never check for leaks with an open flame. Turn on the gas and
apply soapy water to all joints to see if bubbles are formed.
CONNECTING ELECTRICAL SUPPLY
CAUTION! This furnace is designed for negative ground 12 volt DC system
only. Do not attempt to alter the furnace for a positive ground system or
connectthe furnace directlyto 115volts AC.Damage to furnacecomponent
parts will occur.
Be sure all wiring to the furnace is of heavy enough gauge to keep the voltage
drop through it to a minimum and to provide enough powerfor start-up surge. No.
12 gauge wire is recommended.
If any of the original wire that is supplied with the appliance must be replace, it
must be replaced with Type 105°C or its equivalent.
Connect the power supply to the red and yellow wires in the right side of the
furnace. The wires are color coded, red for positive (+) and yellow for negative (-).
This polarity must be observed so the furnace motor will run with the proper
direction of rotation to insure correct air delivery. (See wiring diagram.)
If the furnace power supply is to be from a convertor, we recommend that the
convertor system used to power the furnace be wired in parallel with the battery.
This will serve two purposes:
1. Provide a constant voltage supply to the furnace.
2. Filter any A.C. spikes or volt surges.
NOTE: Furnace Models NT-12S, NT-16S and NT-20S are equipped with an
electric ignitor device that has an energy consumption of .1 amp at 12 volts DC.
CONNECTING DUCTS TO FURNACE
The following duct requirements must be followed in order to assure proper
operation of the furnace.
A. Maintain a minimum of 25 square inches unrestricted duct area throughout
entire duct system including through register. (Minimum 2 ducts 4" diameter.)
NOTE: Ducts terminating in a dead air space (like holding tank compartments or
cargo areas (Toy Boxes) with no means for return air recirculation should not be
counted in the required ductarea. Also, ducts 2" in diameterorsmaller should not
be counted in the required duct area.
B. Make the duct connections at the furnace cabinet tight. Loose connections will
resultin overheatingofthefurnacecomponentpartsandareductionin theheated
air flow through the duct system.
C. Avoid making sharp turns in the duct system. Sharp turns will increase the
static pressure in the plenum area and could cause the furnace to cycle.
D. Avoid making a lot of turns in the duct system. The straighter the duct system
the better the performance of the furnace.
E. Maintain a minimum of 1" clearance where ducts pass through any combustible
construction; such as, coach cabinetry. (See Figure 4A). NOTE: UL listed duct
materials can be 0" clearance.
F. Do not install air boosters in the duct system. Such devices will cause the
furnace to cycle on limit and to have erratic sail switch operation.
NOTE: After installation ofthe furnace and ductsystem is completed, adjustments
must be made to obtain a temperature rise within the range specified on the
Rating Plate.
The efficiency rating of the furnace is a product thermal efficiency rating
determined under continuous operating conditions independent of any installed
system. CONNECTING THERMOSTAT
Locate the room thermostatapproximately 4 1/2 feet above the flooron an inside
bulkhead where it is not affected by heat from any source except room air.
Connectthermostatwires tothebluewires leavingpowersupplyplug on rightside
offurnace.(Seewiringdiagram.)Ifyourfurnace isequippedwith a thermostatthat
has an adjustable anticipator, the anticipator should be set at .7 amps. If you
desire longer heating cycles, adjust the anticipator to a higher setting. Ifyou desire
shorterheating cycles,adjust the anticipator to a lower setting.Adjustments to the
anticipator setting should be made in .5 amp increments.
INSTALLING VENT
The vent outlet must be installed so it is in the same atmospheric pressure zone
as the combustion air intake.The exhaustand intake tubes must beinstalled from
the outside, pass through the RV skin and slide onto the furnace exhaust and
intake.
WARNING! Donotalterthe ventassemblysupplied with this furnace.Any
modifications willresult in improper installation which could cause unsafe
furnace operation.
CAUTION!Combustion air must not be drawn from the living area.Allair for
combustion must be drawn from the outsideatmosphere.Allexhaustgases
must be vented to the outside atmosphere -never inside the RV. Therefore,
it is essential to insure that the vent cap and tube assemblies are properly
installed.
Suburban recommends all vents be installed using the rain shield supplied.
(See Figure 7)
1. Apply caulking to RV skin behind ventcap as shown in Figure 7. Apply caulking
generously around perimeter of vent cap and across center as shown.
2. Insert intake tube through RV skin and slide it onto the furnace intake (See
Figure 1.) Minimum tube overlap of 1/2" is required.
3. Insert vent cap exhaust tube through RV skin and slide it onto the furnace
exhaust (See Figure 1.) Minimum tube overlap of 1 1/4" is required.
4. Attach vent cap assemblyto outer skin of RV with the six (6) screws provided.
Do not install vent assembly upside down. The words "Suburban" and "Dayton,
Tenn." must be right side up.
PREVENTIVE MAINTENANCE
WARNING! If the user of this appliance fails to maintain it in the condition
in which it was shipped from the factory or if the appliance is not used
solely for its intended purpose or if appliance is not maintained in
accordance with the instructions in this manual, then the risk of a fire
and/or the production of carbon monoxide exists which can cause
personal injury, property damage or loss of life.
CAUTION: Label all wires before disconnecting for servicing. Proper polarity
must be observed so the furnace motor will run with the proper direction of
rotation to insure correct air delivery (See Wiring Diagram.)
CAUTION: Label all wires prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous furnace operation.
Always verify proper operation of furnace after servicing.
Your furnace should be inspected by a qualified service agency yearly before
turning the furnace on.Particular attention should be given to the following items.
1. Inspect furnace installation and vent termination to be sure furnace is properly
secured in place (See Installation Instructions), that vent terminates to the
atmosphere, and that vent tubesoverlap properly. (See Installing Vent Assembly.)
2. Inspect chamber and venting to assure that these components are physically
sound, without holes or excessive corrosion and that the installation and/or
reinstallationisinaccordancewith Suburban’s InstallationInstructions.(Reference
installation manual supplied with furnace.)
WARNING! It is imperative that the products of combustion be properly
vented to atmosphere and that all combustion air supplied to burner be
drawn from outside atmosphere.
3. Check the base on which furnace is mounted. Be sure it is physically sound,
void of any sagging, deterioration, etc.
4. Inspectfurnace,the venting,ducting and the gas piping to furnace for obvious
signs of deterioration. Correct any defects at once.
5. Inspect combustion chamber for restrictions in exhaust or intake. It is
imperative that the flow of intake combustion air and the flow of exhaust gases
being expelled to the outside atmosphere not be obstructed. Any soot or loose
debris should be blown out using compressed air. (See Figure 10.)
6. Inspect all gaskets. If any gaskets show signs of leakage of deterioration,
replace them. Safe operation of the furnace depends on all gaskets being tight.
7. Inspect return air inlet openings to the furnace. Remove any restrictions to
assure adequate air flow.
You, as the owner/user, should inspect the furnace monthly during the
heating season for presence of soot on vent. Operating the furnace under this
condition could lead to serious property damage, personal injury or loss of life. If
soot is observed on the vent, immediately shut furnace down and contact a
qualified service agency.
Listed below are several safety related items that you should follow during the
heating season to assure continued safe operation of the furnace.
1. Inspectfurnace venting.Venting mustbe free ofobstructions,void ofsootand
properly terminated to the atmosphere. (See Installing Vent Assembly.)
WARNING! Do not install screens over the vent for any reason. Screens
will become restricted and cause unsafe furnace operation. Accessories
are being marketed for RV products which we do not recommend. For
your safety, only factory authorized parts are to be used on your furnace.
2. Periodically inspect the vent for obstructions or presence of soot. Soot is
formed whenever combustion is incomplete. This is your visual warning that the
furnace is operating in an unsafe manner. If soot is present, immediately shut
furnace down and contact your dealer or a qualified service person.

3. Periodically observe the main burner flame to assure it is burning with a hard
blue flame with well defined burner ports (See Figure 12).If flame appears yellow
or burner has a lazy flame, shut furnace down. It is possible that burner needs
cleaning or replaced.To inspectthe main burner,remove the four (4) screws (A,
B, C and D) securing the burner access door to the combustion chamber (See
Figure 11). If excessive rust and corrosion are present on burner surface, the
burner must bethoroughlycleanedorreplaced.The burnermaybe cleaned using
asteelwirebrushandblowncleanusinghigh compression air.Contacta qualified
service person for assistance.
NOTE:To observeflame,cabinetfront mustbe removed.Operationofburner can
then be observed through the viewing window on front of chamber (See Figure
11).
4. Keep furnace clean. More frequent cleaning maybe required due to excessive
lint from carpeting, bedding material, etc. It is imperative that control
compartments,burners and circulating airpassageways of the appliance be kept
clean.
5. The motor is permanently lubricated and requires no oiling.
6. Keep the furnace area clear of any combustible materials, gasoline or other
flammable vapor and liquids.
7. Before operating furnace, check the location of the furnace vent to make sure
it will not be blocked by the opening of any door on the trailer.If it can be blocked,
do not operate the furnace with the door open.
8. Do not restrict the flow of combustion air or the warm air circulation to the
furnace. To do so could cause personal injury and/or death.
9. Never operate the furnace if you smell gas. Do not assume that the smell of
gas in your RV is normal. Any time you detect the odor of gas, it is to
beconsidered life threatening and corrected immediately. Extinguish any open
flames including cigarettesandevacuateallpersons from the vehicle.Shutoffgas
supply at LP gas bottle. (See safety notice on front cover of this manual.)
10. Immediately shut furnace down and call a service agency if furnace cycles
erratically or delays on ignition.
WARNING! Should overheating occur, or the gas supply fail to shut off,
shut off the manual gas valve to the appliance before shutting off the
electrical supply.
11. Never attempt to repair damaged parts. Always have them replaced by a
qualified service agency.
12. Never attempt to repair the furnace yourself. Seek the help of a qualified
service person.
13. Never restrict the ducting installed by your trailer manufacturer. To do so could
cause improper furnace operation.
14. Do not install air boosters in the duct system. Such devices will cause the
furnace to cycle on limit and to have erratic sail switch operation.
15. Clothing or other flammable material should not be placed on or near the
appliance.
16. Always follow theOperating Instructions. Do not deviate from the step-by-step
procedures.
17. Do not use this appliance if any part has been submerged under water.
Immediately call a qualified service technician to inspect the appliance and to
replace any part of the control system and any gas control that has been
submerged under water.
18. When considering add-on rooms, porch or patio, attention must be given to
the venting of your furnace. For your safety, do not terminate furnace vent inside
add-on rooms, screen porch or onto patios. Doing so will result in products of
combustion being vented into the room or occupied areas.
19. In anyinstallationin which the ventofthis appliance can becovered dueto the
construction of the RV or some special feature ofthe RV such as slide out,pop-up
etc. always insure that the appliance cannotbeoperated bysettingthe thermostat
