Hydrogen gas isextremely flammable and explosive.
To prevent the possibility of injury under these con-

ditions, we recommend the hot water faucet be
opened for several minutes at the kitchen sink

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

present, there will probably be an unusual sound
similar to air escaping through the pipe as the hot
water faucet is opened. There must be no smoking

or open flame near the faucet at the time it isopen.

&WARNINGbe _ Figure 6 ' __

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
the water heater's pilot or turning on a nearby elec-

by sniffing at ground level in the vicinity of the
