WARNING

Liquefied petroleum gases/propane gas are heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas. Be sure to smell next to the floor.

IF YOU SMELL GAS:

•Do not try to light any appliance.

•Do not touch any electric switch; do not use any telephone in your building.

•Immediately call your gas supplier from a telephone in another building. Follow the gas supplier’s instructions.

•If you cannot reach your gas supplier, call the fire department.

DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!

IMPORTANT

The flow of combustion and ventilating air must not be obstructed.

Provide adequate air for combustion and ventilation. An insufficient supply of air will cause recirculation of combustion products resulting in air contamination that may be hazardous to life. Such a condition often will result in a yellow, luminous burner flames, causing carboning or sooting of the burners and flue tubes with possible damage to the heater.

Confined Spaces

If the water heater is installed in a confined space (volume is less than 50 ft.3/1000 BTU (15 m3/0.29 kW) per hour of the total input rating of all gas appliances in that space), air must be supplied through two permanent openings. One opening shall be within 12 inches (30.5 cm) from the top of the enclosure and one within 12 inches (30.5 cm) of the bottom. The openings must be protected by metal louvers or 1/4” (6.4 mm) min. mesh metal screen. The size of the openings are as follows.

1.If the openings communicate directly with an additional room(s) of sufficient volume, each opening shall have a minimum free area opening of 1 in.2/1000 BTU (2.54cm2/0.29kW) per hour of the total input rating of all gas appliances in the confined space, but not less than 100 in.2 (254 cm2).
