]To prevent the possibility of injury under these con-

before any electrical appliances which are connected to the hot water system are used (such as a dish- washer or washing machine). If hydrogen gas is pre-

Lighting

_WARNING __

BEFORE LIGHTING [PROPANE (L.P.) GAS WATER HEATERS]: Propane (L.P.) gas is heavier than air.

Should there be a leak in the system, the gas will settle near the ground. Basements, crawl spaces,

skirted areas under manufactured (mobile) homes (even when ventilated), closets and areas below

ground level will serve as pockets for the accumula- tion of this gas. Before attempting to light or relight [ Figure 6 1

the water heater's pilot or turning on a nearby elec- trical light switch, be absolutely sure there is no

accumulated gas in the area. Search for odor of gas by sniffing at ground level in the vicinity of the

appliance. If odor isdetected, follow steps indicated at "For Your Safety" on the cover page of this man-

ual then leave the premises.

Lighting and operating instructions are located on front of

the water heater, above or to one side of the gas control valve.

[Figure,]

AWARNING

AN ODORANT IS ADDED TO THE GAS USED

BYTHIS WATER HEATER. _

FOR YOUR SAFETY IF YOU SMELL GAS:

• Do not try to light any appliance.

• Do not touch any electrical switch; do not use any

phone in your building.

• Immediately call your gas supplier from a neigh- bor's phone. Follow the gas supplier's instructions.

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

[ Figure 8 ]

AWARNING

DO NOT force the gas control knob. Use only your hand to push it down to light the pilot, or to turn it

to "ON", "OFF" or "PILOT". Never use a tool such as

a lever, wrench or pliers. Do not hit or damage the knob. A damaged knob may result in an explosion

and serious injury. If you have problem turning the knob, call the gas supplier immediately.
