GENERAL INSTALLATION

This is a common installation for water heaters. There are other
approved methods such as Baggage Compartment (MPD 90093) and
Flush Mount (MPD 93948) installations. Consult with your Field
Auditor, Account Manager, or the Atwood Service Department if you
have additional questions.
1. Locate water heater on floor of coach before erecting side walls.

The water heater tank must be permanently supported at the same
level as the bottom of sidewall cutout (by the floor or a raised floor)

FIG

2. Provide adequate clearance at rear of unit for service of water

connections.

2. To install water heater on carpeting, you must install appliance on a

metal or wood panel that extends at least three inches beyond the
full width and depth of appliance.

3. If the appliance is installed where connection or tank leakage will

damage adjacent area, install a drain pan (which can be drained to
out side of coach) under water heater.

WIRING

All wiring must comply with applicable electrical codes.

COMBINATION GAS/ELECTRIC MODELS

are designed to operate with gas,

electricity, or a combination of both.

• Use electrical metallic tubing, flexible metal conduit, metal clad

cable, or nonmetallic-sheathed cable with grounding conductor. Wire
must have a capacity of 1400 watts or greater. The wiring method
must conform to applicable sections of article 551 of National
Electrical Code ANSI/NFPA 70.

1. Refer to 

Wiring Diagram

(

FIG

12). Make 120 VAC electrical

connections from junction box on back of unit.

a. Connect hot lead to (1) Black. 
b. Connect common lead to (2) White.
c. Connect ground wire from electrical service to (3) green ground

lead in junction box 3.

CAUTION

PRODUCT DAMAGE

• When using Romex

®

with a bare earth ground, take care to position

ground wire so it does not contact the heating element terminals.

• When a cord and plug connection to the power supply are used on

water heater, power cord must be UL listed as suitable for damp
locations, hard or extra hard usage. It must be a flexible cord such
as type S, SO, ST, STO, SJ, SJT, SJTO, HS or HSO cord as described
in National Electrical Code, ANSI/NFPA 70. The length of external
cord to water heater, measured to face of attachment plug, shall be
no less than 2 feet nor more than 6 feet. Supply cord must be a
minimum of 14 AWG and attachment plug must be rated at 15 amps.

CAUTION

ELECTRICAL DAMAGE

• 

Label all wires before disconnecting when servicing controls.

• 

Verify proper operation after servicing.

ELECTRONIC IGNITION 

NOTE

: It is recommended unit be connected directly to a 12V DC

battery or to filtered side of an AC/DC converter. Avoid connections to
unfiltered side of an AC/DC converter whenever possible. Use a
minimum of 18 gauge wire, UL and CSA listed.

1. Refer to 

Wiring Diagram

(

FIG

12). Install remote switch in a

convenient location. Position wall plate with letters up. Before
making connections turn switch 

OFF

2. Install wires see

1. Push a 5/8˝ diameter coolant system hose (5-A) [with SAE 053 A

Type “E”clamp attached] onto heat exchanger tube (5-B) making a
tight connection.

2. Spread hose clamp and slide toward heat exchange unit past

annular groove (5-C) and release.

4. Connect both 1/2˝ NPT water lines (

FIG

2) hot water outlet female

and cold water inlet female and 3/8˝ flared LP gas line to the water
heater (

FIG

9).

a. Allow flexibility in water and gas lines so you can pull unit

forward through wall one inch past skin.

b. Seal gas line entrance opening (

FIG

9) by sliding grommet (9-B)

onto 3/8˝ tubing (9-D) before flaring tubing (9-E). Pull gas line and
grommet through opening in housing (9-A). Connect flare fitting
(9-C) and press grommet into opening. If gas line tubing is
already flared, cut grommet on one side. Place split grommet
over gas line and press it into opening.

c. Always use pipe lubricant on threads when connecting hot and

cold water couplings. A suitable plastic fitting is recommended.

CAUTION

PRODUCT DAMAGE

• Do not lift, pull or push on main burner tube (

7. To prevent water leaks caulk thoroughly around opening, including

bend slots. Butyl Tape (1-1/3˝x1/8˝) may be substituted for caulking
material.

8. Push unit against caulking, secure 4-corner brackets (

FIG

3-B) to

coach with No. 8 - 3/4˝ round head screws (not furnished) or equivalent.
