7.

Do not locate fuel gas containers or  fuel supply
hoses anywhere near the discharge outlet of the
heater.

8.

Do not block air intakes or discharge outlets of the
heater.  Doing so may cause improper combustion or
damage to heater components leading to property
damage.

9.

The hose assembly shall be visually inspected on a
