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.
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.
