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.
