Installing the water heater

The installation of this water heater must be in accordance with the Manufactured Home Construction

and Safety Standard (Title 24, CFR; Part 3280) and the following instructions; instructions supplied with

the roof jack assembly, local codes, and utility company requirements governing the installation of water

heaters in manufactured homes (mobile homes) and/or in the absence of local codes, the latest edition of

The National Fuel Gas Code, ANSI Z223.1/NFPA 54.

Location

This water heater must be installed within

an enclosure so as to separate the water

heater's combustion and venting system

from the interior atmosphere of the

manufactured home.

All air for combustion must be obtained

from the outside atmosphere, and the

products of combustion (flue gases) must

be discharged directly to the outside

atmosphere through the gas vent roof

jack assembly. There must not be any

door or other opening into the water

heater enclosure from the inside of the

manufactured home.

Refer to installation methods A as shown

on page 9 of this manual. The water heater

enclosure access panel (door) must be in

the outside wall of the manufactured home.

Any opening for piping must be sealed.

Minimum ceiling height within enclosure is

6 ft 6 in.

The water heater should not be located

in an area where leakage from the tank

or connections will result in damage to

the area adjacent to the heater or to lower

floors of the structure.

When such areas cannot be avoided it is

recommended that a suitable drain pan,

adequately drained, must be installed under

the water heater.

The pan must not restrict air flow to the

combustion air inlet openings (perforation

openings) located around the lower

perimeter of the water heater.

Drain pan kits are available from the store

where the water heater was purchased, or

any water heater distributor.

Make certain the floor underneath the water

heater is strong enough to sufficiently

support the weight of the water heater once

it is filled with water.

A gas fired water heater or any other

appliance should not be installed in a space

where liquids which give off flammable

vapors are to be used or stored. Such

liquids include gasoline, LP gas (butane

or propane), paint or adhesives and their

thinners, solvents or removers.

When installed in a closet, DO NOT block

or obstruct any of the combustion air inlet

openings located around the perimeter of

the water heater. A minimum of 1 in. is

required between these combustion air inlet

openings and any obstruction.

Because of natural air movement in a room

or other enclosed space, flammable vapors

can be carried some distance from where

liquids which give off flammable vapors

are to be used or stored. The open flame

of the water heater’s pilot or main burner

can ignite these vapors and create a shut

down condition of the water heater which

will not allow the water heater to ignite

until examined by a Qualified Service

Technician.

● Long hot water lines should be insulated

to conserve water and energy.

● The water heater and water lines should

be protected from exposure to freezing

temperatures.

● Minimum clearance from combustible

construction:

* "Front" Clearance is measured from

the gas control (thermostat) to the closet

door.

** "Top" Clearance is measure from

the jacket top of the water heater to the

ceiling.

If the clearances stated on the Instruction/

Warning Label, located on the front of

the heater differ, install the water heater

according to the clearances stated on the

label.

● If the water heater is installed in an

alcove or closet, the entire floor must

be covered by a wood or metal panel.

A minimum of 24 in. Clearance from

the front and top should be available for

adequate inspection and servicing.

● The water heater may be installed on

combustible floors, but not directly on

carpeting. If the water heater must be

installed on carpeting, place a metal or

wood panel beneath the water heater,

extending beyond its full width and depth

at least 3 in. in all directions.

NOTICE: For proper operation and

maintenance, a minimum clearance

of 1-1/2 in. must be provided from

the combination temperature and

pressure relief valve to any wall or

object.

WARNING:

Combustible construction

refers to adjacent walls

and ceilings and should

not be confused with

combustible or

flammable products and

materials. Combustible

and/or flammable

products and materials

should never be stored in

the vicinity of this or any

gas appliance.

CAUTION: Provisions

should be made so that in

the event the water heater

or one of its fittings were

to leak, the resulting

flow of water will not

cause damage to the

manufactured home.

The auxiliary drain

pan installation MUST

CAUTION: DO NOT

subject the water heater

to any water distribution

system air pressure test. The

water heater should either

be isolated with valves at

the inlet and outlet water

connections or disconnected

during the test. Failure

to properly isolate the

water heater during an air

pressure test presents a

hazard to life and property.

With a water pressure test

the water heater need not be

isolated.
