THESE CONDITIONS CAN RESULT IN UNSEEN INTER- NAL DAMAGE and are not subject to warranty coverage.

CAUTION

Hydrogen gas can be produced in a hot water system served by this heater that has not been used for a long period of time (generally two (2) weeks or more).

Hydrogen gas is extremely flammable and can ignite when exposed to a spark or flame. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance con- nected to the hot water system. Use caution in opening faucets. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at the time it is open.

CAUTION:

Possible cancer hazard by inhalation. Can cause respiratory, skin and eye irritation.

This product contains fiberglass wool and ceramic fiber materials. Airborne fibers from these materials have been listed by the State of California as a possible cause of can- cer through inhalation. Use special care when handling ceramic fiber (chamber lining and base insulation) materials. Ceramic fibers can be converted to chrystobalites, a sub- stance listed as a probable cause of cancer. Suppliers of fiberglass wool products recommend the following mea- sures be taken when handling these materials:

Precautionary measures:

•Avoid breathing fiberglass dust.

•Avoid contact with skin and eyes.

•Use a National Institute for Occupational Safety and Health (NIOSH) approved dust/mist respirator.

•Wear long-sleeved, loose fitting clothing, gloves and eye protection.

•Wash work clothes separately from other clothing. Rinse

washer thoroughly.

Removing the burner may generate airborne fiber concen- tration requiring additional protection.

First aid measures:

•Eye contact - Flush eyes with sterile water to remove for- eign objects. If irritation or other symptoms persist, seek medical attention.

•Skin contact - Wash affected areas gently with soap and warm water after handling.

WARNING

•Do not use gasoline, crank case oil or an oil containing gasoline.

•Do not tamper with unit or controls.

Location Requirements

The water heater must be installed indoors in an area not subject to freezing temperatures and in a vertical position on a level surface. Water heaters located in unconditioned spaces (e.g., attics, basements etc.) may require insulation of the water piping, drain piping and venting to protect against condensation.

The water heater must be installed on a non-combustible floor, as close to the chimney as practical. Select a location as centralized within the piping system as possible. The heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the water heater or to lower floors of the struc- ture (see “IMPORTANT” notice on the following page). Before installing this water heater, consideration and plan- ning must be given to the following details:

•Proximity to walls and other objects (see Figures 1, 2 & 3).

•Access to oil supply (see “Oil Supply”).

•Routing and support of the vent piping and termination (see “Venting”).

•Position of water supply and placement of water piping and floor drain (see “Water Supply”).

•How and where to obtain combustion and ventilation air supply. (see “Air Requirements”).

•Connection to the electrical service. (see “Electrical Supply”).
