American Dryer Corp GWH 425 EF manual

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 gas fired water heater installation in bathrooms, bedrooms or any occupied rooms normally kept closed. See the section below on locating the heater.

4.You must install your heater so that the venting complies with all requirements. See section on Venting the Heater, pages 6 and 7.

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 during any pressure testing of the gas supply piping system at test pressures in excess of 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 that might burn. Do not install heater over carpeting.

7.Correct gas pressure is critical for the optimum operation of this heater (see specifications on page 2 and chart on page 9). Gas piping must be sized to provide the required pressure at the maximum output of the heater. 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 under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control that has been under water.

10.When installed, the appliance must be electrically grounded in accordance with local codes or, in the absence of local codes, in accordance with the National Electrical Code ANSINFPA 70 and/or the CSA 22.1 Electrical Code.

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. Before installing the unit, be certain you have the correct heater for your type of Gas – Propane or Natural Gas. Identification labels are found on the shipping box, and on the rating plate which is located on the right side panel of the cover. Also, each burner orifice is stamped with a number (79 for LPG and 120 for Natural Gas).

Follow the guidelines below:

1.National building codes require that you do not install this appliance in bathrooms, bedrooms, unvented closet or any occupied rooms normally kept closed.

2.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 425 EF is venting properly when all these other appliances are running. See page 6 to test venting performance.

Do not obstruct the flow of combustion air to the appliance. This appliance is power vented and uses room air. Note: Electrical power is required to operate the power exhaust. Proper air supply to the appliance is essential.

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 vent blockage and poor, unsafe combustion.

3.Your hot water lines should be kept short to save energy. It is always best to have hot water lines insulated.

WARNING: DO NOT INSTALL IN AN AREA WHERE IT COULD FREEZE. This heater is neither designed for nor approved for outside installation. Drain the heater entirely if freezing temperatures are anticipated in area where heater is installed by disconnecting both the inlet and outlet water connections from the heater (disconnect the outlet flex line from where it connects to the copper heat exchanger). Additionally, remove the drain plug under the water valve. See Fig 1.

WARNING: Flammable materials, gasoline, 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.
