LEAK TESTING HEATER GAS CONNECTIONS:

1. Open manual shutoff valve.
2. Open main gas valve located near gas meter.
3. Make sure control knob of heater is in the OFF position.
4. Check  all joints from  manual gas valve  up to gas control and including  the

manifold assembly. Apply  the soap solution  around the connections,  valve and
tubing.  Soap bubbles will appear where a leak is present.

5. If a  leak is present, immediately turn  off gas supply, tighten any leaky  fittings,

turn gas on and recheck.

6. To check burner and safety valve, the burner must be lit (See operating

Instructions.). Check the rest of the connections for leaks.

7. Turn off the heater (See Instructions.).

NOTE:

Never use an open flame to check for a leak. Apply a mixture of liquid soap
and water to all joints. Bubbles forming show a leak. Correct all leaks at
once.

OPERATING HEATER:

WARNING:

Before lighting smell  all around the appliance  area for gas. Be  sure to smell
next  to the floor because  some gas is  heavier than air  and will settle  on the
floor. If  you smell gas, follow the Safety Instructions on the front page and
under Section I.
