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 (

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.
