We thank you for choosing a GSW or John Wood Water Heater. Your satisfaction with this product is very important to us.

The design of this gas-fired water heater has been approved to provide potable hot water or when combined with a suitably-sized fan coil, baseboard heater, etc., to provide both space heating and domestic hot water.

Important Consumer Notice

These instructions have been written for the proper installation, safe operation and maintenance of this water heater.

It is your responsibility to ensure that your water heater is properly installed and cared for. FAILURE TO FOLLOW THE

INSTRUCTIONS IN THIS MANUAL MAY RESULT IN SERIOUS BODILY INJURY AND /OR PROPERTY DAMAGE. THOROUGHLY READ ALL INSTRUCTIONS

before you attempt to install or operate this heater.

Installation and service require trade knowledge in the area of plumbing, venting, air supply and gas supply. If you lack these skills or do not understand these instructions, enlist the help of a qualified professional.

GSW Water Heating Company, the manufacturer of this water heater, cannot be held liable for those damages caused by improper installation, sizing or failure to comply with these instructions. Protect your warranty: Regularly

maintain your water heater and venting system as detailed in the service and maintenance section of this manual.

Installation Code Requirements

In addition to the installation instructions found in this manual, the heater shall be installed in accordance with local codes or , in the absence of local codes, the latest edition of CAN/CGA B149.1 installation code in Canada / National Fuel Code ANSI Z223•1 (NFPA 54) in the USA.

Authorities having jurisdiction shall be consulted before installations are made.

Important: All supply equipment, installation, approvals, permits, inspections, etc. are the responsibility of the owner of this water heater. Consult your local authorities for regulations specific to your area.

Relief Valves (T&P)

All heaters must be installed with a proper temperature and pressure relief valve. These valves must be certified as meeting the requirements for Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21•22 in the USA / CAN1-4.4, Temperature, Pressure, Temperature and Pressure Relief Valves and Vacuum Relief valves in Canada.

Backflow Prevention

Certain jurisdictions may require the installation of a backflow prevention device (e.g., check valve) in the water supply line. Such a device will require the use of a system expansion tank of adequate size to control the thermal expansion generated during the heating cycle. Consult your water supplier or local plumbing authority.

Important: The supply water meter may have a built-in check valve device. Contact your local water authority.

Safety Warnings

•Water Heaters are heat-producing appliances. To avoid damage or injury, no materials shall be stored against the heater and provision shall be made to prevent unauthorized contact (e.g. children).

•Hot water produced by this appliance can cause severe burns due to scalding. The hazard is increased for young children, the aged, or the disabled where water temperatures exceed 120OF(49OC).

•Use anti-scald valves, set to 120OF(49OC), in the hot water system to reduce the risk of scalding at points of use such as lavatories, sinks and bathing facilities. Such precautions must be followed when this heater is operated in combination with dishwashing or space heating applications.

•As with all fuel burning equipment, this heater requires an adequate supply of air for combustion and ventilation. An insufficient air supply can result in poor combustion or the re- circulation of the exhaust flue gases. Such a condition can cause sooting or present a fire hazard, which may result in

serious bodily harm or death from asphyxiation.

MAKE SURE THE FLOW OF COMBUSTION AND VENTILATION AIR IS NOT RESTRICTED.

•Important:There is a risk in using fuel-burning appliances such as water heaters. Areas that may not be suitable for water heater installation include those where flammable liquids, gasoline, solvents, adhesives, etc., or engine-driven equipment or vehicles are stored, operated or repaired. Due to the nature of air movement, flammable vapors can be carried some distance from the point of storage. The gas-fired water heater pilot or main burner flame can ignite these vapors causing a flashback, fire or explosion which may result in serious personal injury or death, as well as severe property damage.

FOR YOUR SAFETY, DO NOT STORE OR USE GASOLINE OR OTHER FLAMMABLE, COMBUSTIBLE OR CORROSIVE VAPORS OR LIQUIDS IN THE VICINITY OF THIS HEATER OR ANY OTHER APPLIANCE.

•If installation in a garage or shed is the only option, it is required that the water heater be elevated a minimum of 18”(45 cm) above the floor level. This may reduce, BUT NOT ELIMINATE, the risk of flammable vapors being ignited. Ensure supports are capable of supporting this heater filled with water and support piping. Such installations must be protected from impact or physical damage caused from moving equipment or vehicles. CHECK LOCAL CODES!

•Exposure to air borne chemicals can cause severe corrosion to the water heater and damage to the venting parts. Air containing vapors from cleaning solvents, pool chemicals, refrigerator or air conditioning refridgerants, laundry detergents or bleaches, waxes, spray can propellants, dry cleaning, photo processing liquids, calcium and sodium chloride (softener salt) or other process chemicals are typical of compounds which are potentially corrosive. Products of this type should not be stored near the heater. Air containing these chemicals should not be used as supply to the heater. If necessary, uncontaminated air shall be obtained from remote or outside sources.

EXPOSURE TO WATER

IMPORTANT: Should the water heater be subjected to flooding, freezing, fire, or other unusual condition, turn off gas at the manual gas shut-off valve and water at the inlet valve to the heater. Do not put the heater in operation until it has been thoroughly checked by a qualified gas technician.

THESE CONDITIONS CAN RESULT IN UNSEEN INTERNAL DAMAGE and are not subject to warranty coverage.
