Locate cabinet cutout location and cut hole per type of installation

being used.

Install adapter by removing the large knockout from the rear of the

casing and attach the 5" duct adapter or optional 5" to 4" inch

adapter.

Fasten 5" duct to the adapter and to the back of the interior grill

and secure.

On installations with 1" or less space between 5" adapter and grill,

the grill can be inserting directly into the adapter to complete the

connection.

Secure grill to cabinet by fastening with screws.

FIRE OR EXPLOSION

Never check for leaks with an open flame. Turn on the gas and apply

soapy water or leak detect solution to all joints to see if bubbles are

formed.

PROPANE GAS CONNECTION

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 .5 PSI.



Before furnace is connected, piping systems are to be tested to

be leak free. The test must maintain air pressure of at least 6" of

mercury or 3 PSI for at least 10 minutes.



The entire piping system is to be adjusted to and maintain a

pressure of 10" to 13" W.C. when all appliances are in operation.



Test gas connections for leakage with soapy water or a leak

detect solution.



If local codes allow the use of a flexible gas appliance connector,

always use a new listed connector. Do not use a connector which

has previously serviced another gas appliance.

WARNING

Connect gas line to the fitting located on the valve through hole in

top of casing or if supplied with an extended manifold at the rear

of the furnace.

Be sure all male pipe threads, other than flare fittings, are treated

with a sealing compound resistant to the action of propane (LP)

gas. DO NOT put sealing compound on flare fittings

Remove grommet plug from furnace. After inserting gas line

through gas plug and connecting to valve re-install gas plug this is

a required air seal.

Insert gas line through grommet plug (DO NOT CUT GROMMET).

Connect gas line inside furnace casing immediately ahead of gas

control valve or at the rear when extended manifold is supplied.

Use two wrenches to hold brass fitting and flare nut when

tightening gas line to brass fitting. DO NOT twist valve assembly.

DO NOT twist valve assembly, torque fitting to 20-22 ft. lbs.

ELECTRICAL CONNECTIONS

INJURY OR PROPERTY DAMAGE

 Label all wires before disconnecting for servicing. Wiring errors can

cause improper and dangerous operation. Verify proper operation

after servicing.

 Disconnect electrical power before servicing.

PROPERTY DAMAGE

This connection is for low-voltage battery or direct current only. Do not

connect to 120 or 240 volts AC.

INSTALLATION AND SAFETY CODES



USA and Canada – follow all applicable state and local codes in

the absence of local codes or regulations, refer to current

standards of:



ANSI/NFPA 1192 Recreational Vehicles Code and ANSI/RVIA LV

Low Voltage Systems in Conversion and Recreational Vehicles

POWER SUPPLY

Atwood Mobile Products highly recommends the use of an electronic

(solid-state) converter with clean power output. This will assure

extended life of the electronic controls and motor beyond typical linear

converter applications.
