water heater installation in bathrooms, bedrooms or any

occupied rooms normally kept closed. See the section

below on locating the heater.

4. You must vent your heater. See section on Vent Pipe

Connections, Page 6.

5. The appliance must be disconnected from the gas

supply piping system during any pressure testing at

pressures in excess of 1/2 Psig (3.5 kPa).

The appliance must be isolated from the gas supply piping

system by closing its individual manual shutoff valve during

any pressure testing of the gas supply piping system at

test pressures equal to or less than 1/2 Psig (3.5Kpa).

The appliance and its gas connection must be leak tested

before placing the appliance in operation.

6. Keep water heater area clear and free from

combustibles and flammable liquids. Do not locate the

heater over any material which might burn.

7. Correct gas pressure is critical for the optimum

operation of this heater (see specifications on page 2).

Gas piping must be sized to provide the required pressure

at the maximum output of the heater, while all the other

gas appliances are in operation. Check with your local gas

supplier, and see the section on connecting the gas supply.

8. Should overheating occur or the gas supply fail to shut

off, turn off the gas supply at the manual gas shut off valve

on the gas line.

9. Do not use this appliance if any part has been

underwater. Immediately call a qualified service technician

to inspect the appliance and to replace any part of the

control system and any gas control which has been

underwater.

PROPER LOCATION FOR INSTALLING YOUR

HEATER

Carefully select the location of your new heater. For your

safety and for proper heater operation, you must provide

an abundant supply of combustion air and a proper venting

installation.

The heater may still operate even when improperly vented.

It will, however, be less efficient and could eventually

damage the heater. It could even result in human sickness

or death due to oxygen deprivation and carbon monoxide

poisoning. Follow the guidelines below:

1. Place your heater as close to a vent or chimney as

possible.

2. National building codes require that you do not install

this appliance in bathrooms, bedrooms or any occupied

rooms normally kept closed.

3. Simultaneous operation of other appliances such as

exhaust fans, ventilation systems clothes dryers, fireplaces

or wood stoves could create a vacuum effect in your home

which could cause dangerous combustion by-products to

spill back into your home rather than venting to the outside

through the flue. Confirm that your Aquastar is venting

properly when all these other appliances are running. See

section on venting.

Do not obstruct the flow of combustion and ventilation

air to the appliance. If installed near a clothes dryer it is

very important that the dryer be properly vented. Failure

to properly vent a dryer could result in a gradual

accumulation of lint on the water heater fin coils and

burners, leading to a dangerous condition of venting

blockage

4. Your hot water lines should be kept short to save energy.

It is always best to have hot water lines insulated. Having

a floor drain or sink nearby is handy in case you need to

drain water from your heater.

WARNING: The water in this water heater is cold and

always remains cold except for the times that hot water is

being used DO NOT INSTALL IN AN AREA WHERE IT

COULD FREEZE.

This heater is neither designed for nor approved for

outside installation.

WARNING:

Flammable

pressurized containers, or any other items or articles

that are potentially fire hazards must NOT be placed

on or adjacent to the heater. The appliance area must

be kept free of all combustible materials, gasoline and

other flammable vapors and liquids.

COMBUSTION AIR REQUIREMENTS

Observe the following instructions concerning combustion

air.

Appliances located in unconfined spaces:

a) An unconfined space is one whose volume is greater

than 50 cubic feet per 1000 Btu per hour of the combined

rating of all appliances installed in the space. That would

be 5850 cubic feet for the AquaStar 125X alone.

b) In unconfined spaces in buildings of conventional frame,

masonry, or metal construction, infiltration is normally

adequate to provide air for combustion, ventilation, and

dilution of flue gasses.

Appliances located in confined spaces:) The confined

space must be provided with two permanent openings,

one commencing within 12 inches of the top and one

commencing within 12 inches of the bottom of the

enclosure. Each opening must have a minimum free area

of one square inch per:

- 1000 Btu/hr if all air is taken from inside the building.

- 2000 Btu/hr if all air is taken from the outside by horizontal

ducts.

- 4000 Btu/hr if all air is taken from the outside by direct

openings or vertical ducts.

Louvers, grills and screens have a blocking effect. If the

effective free area is not known, increase the sizes of your

openings by 75% if your louvers are wood and by 30% if

your louvers are metal. Refer to the National Fuel Gas

Code for complete information. In buildings of tight

construction all air should be taken from outside.
