GENERAL INSTALLATION

Below is the most common type of installation for the water heater.

However, there are other approved methods such as baggage com-

partment (refer to MPD 90093) and flush mounting installations (refer

to MPD 93948). Consult 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).

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 water heater is installed where leakage of connections or tank will

damage adjacent area, install a drain pan which can be drained to

out side of coach, under water heater.

4. Connect both 1/2˝ NPT water lines - hot water outlet female

(

1-A) and cold water inlet female (

FIG

lines (

1-C).

FIG

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

ward through wall one inch past skin (

b. Seal gas line entrance opening by sliding grommet (

3/8˝ tubing (

1-F) before flaring tubing (

and grommet through opening in housing (

fitting (

1-E) and press grommet into opening. If gas line tubing

FIG

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.

PRESSURE-TEMPERATURE RELIEF VALVE

This water heater is equipped with a temperature and pressure relief

valve (

relief valve.

If you use a discharge line, do not use a reducing coupling or other

restriction smaller than outlet of relief valve. Allow complete drainage

of both valve and line.

FOR REPLACEMENT PARTS:

•

install anything less than a combination temperature-pressure

relief valve certified by a nationally recognized testing laboratory that

maintains periodic inspection of product of listed equipment or materi-

als, as meeting requirements for Relief Valves and Automatic Gas

Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22. Valve

must have a maximum set pressure not to exceed 150 psi.

• Install valve into opening provided and marked for this purpose on

water heater.

• Installation must conform with local codes or in the absence of local

codes, American National Standard for Recreational Vehicles, ANSI

A119.2/NFPA 50IC.
