A "ou,o*
PROPERTY DAMAGE
This connection is for low-voltage battery or direct current only.
Do not connect to 120 or 240 volts AC.
. This furnace is designed for negative ground 12 volts DC only. DO
NOT attempt io alter lurnace for a positive ground system or
connect the f urnace directly to 120 volts AC. Damage to furnace
components will occur and warranty will be voided.
. Use a minimum of 1B GA wire to minimize voltage drop. Furnace
must be installed so electrical components are protected from
water. To make electrical connections see wiring diagrams.
. For best furnace performance when power supply is from a
converter equipped with a charging port, wire converter to furnace
parallel with battery. This provides consistent voltage to-furnace,
increasing component life, filtering power surges and AC spikes'
. Some models are shipped with a lield harness connections with 12"
wire leads on a terminal block.
. AII units are supplied with a power switch which when turned off
during servicing will remove power through furnace wiring. Switch
must be in the ON position for furnace to operate.
. The direct high voltage spark ignition generates a radio lrequency
that could cause interference with other microprocessor-based
equipment. Locate equipment at least five feet (5') from furnace
locaiion. lf this distance cannot be maintained a shielded high
voltage lead can be ordered. See parts list.
1. Route wiring to left side of lurnace.
2. Connect red wire to positive side of power supply.
3. Connect black wire to grounded side of power supply.
4. Connect blue wire marked positive thermostat to + side wire of
thermostat using 22-18 GA stranded wire.
5. Connect other blue wire to the other thermostat lead-using minimum
22-18 GA stranded wire.
POWER SUPPLY
Atwood Mobile Products highly recommends the use of an electronic
(solid state) converter with clean power output. This will assure the li{e of
ihe electronic controls and motor life could be extended beyond typical
linear converter applications.
THERMOSTAT INSTALLATION
o Thermostats are not supplied. To purchase a thermostat rated for
12VDC or 24VAC, Minimum 1 AMP rating, they can be ordered
through Atwood. See Parts list.
o Be sure all electrical power has been disconnected lrom the air
conditioner, furnace, and the power supply.
. The thermostats are very sensitive. HANDLE WITH CARE AT ALL
TIMES.
. Pick a dry area where air circulation is good.
. Do not install the thermostat where there are unusual heating
conditions: such as direct sunlight, heat producing appliances
(television, radio, wall lamp, etc.) or a furnace or air conditioner
output registers.
Locate thermostat 48" to 54" above main living area iloor on an
INTERIOR wall when possible.
EXTERIOR wall location must have a 3/4" spacer between

2. Set thermostat above room temperature to begin blower operation.
A slight delay will occur before the blower comes on. Allow blower
to run for 1 minute for combustion chamber purge cycle. lf blower
does not come on go to shut down and contact your dealer or a
' Iocal recreational vehicle service agency.
3. After 1 minute, the blower may not be running at this time, move
thermostat lever below room temperature. Wait approximately 2
minutes for blower to go otf.
4. Open manual shut-off valve (if so equipped) or the valve at the
' outside LP tank. Correct operation characteristics depend on the
valve being positioned fully open. Never attempt to operate with a
valve partially closed. Turn shut-off switch to "ON" position.
5. Set thermostat lever to desired setting. lf set above room
temperature, blower will come on.
6. Allow 30 seconds for main burner to light after blower comes on.
This furnace is equipped with an ignition device which automatlcally
lights the burner. DO NOT try to light the burner by hand.

Do not force.
SYSTEM CHECKS
A wannrnc
FIRE OR EXPLOSION
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.
PROPANE GAS PRESSURE TEST
The furnace and any individual shut-off valve must be disconnected from
gas supply piping system during any pressure testing of system at test
pressures of more than 1/2" PSl.
Before furnace is connected, piping systems must be tested to be leak
free. The test must maintain air pressure of a least 6" of mercury or 3"
PSI for at least 10 minutes.
The entire piping system must be maintained within a range of 10 to 14"
WC when all appliances are in operation. Test gas connections for
leakage with a leak test solution.
STATIC PRESSURE TEST
. Special tools required to take casing static pressures.
Please refer to Engineering addendum when installing the {urnace. This
will provide you with allowable maximum case static pressures with each
possible variation of duct configurations. The addendum is available from
you Atwood Field Service Representative or by calling Atwood Service.
Reducing the number of duct turns and stretching the ducts will increase
airflow and reduce static pressure. Adding ducts or increasing the
discharge (hard duct) system will also reduce static pressure.
You must follow the manufacture's recommendations and specifications
for optimum performance and proper operation.
IGNITION CONTROL DIAGNOSTIC CODES
The following charts give the diagnostic codes given by the ignition
control when faults are present.
. A soft lockout is a condition that is timed and will make additional
attempts to correct the problem. A hard lookout requires resetting oJ
the thermostat or turning the power switch oJf, then back on.
