GENERAL RULES TO FOLLOW

FOR SAFE OPERATION

1. You should follow these instructions when you install

your heater. In the United States: The installation must

conform with local codes or, in the absence of local codes,

the National Fuel Gas Code ANSI Z223.1/NFPA 54.

In Canada: The Installation should conform with CGA

B149.(1,2) INSTALLATION CODES and/or local

installation codes.

2. Carefully plan where you install the heater. Correct

combustion air supply and flue pipe installation are very

important. If not installed correctly, fatal accidents can be

caused by lack of air, carbon monoxide poisoning or fire.

3. The place where you install the heater must have

enough ventilation. The National Fire Codes do not allow

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 4.

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, unvented closet

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 and poor unsafe combustion.
