* An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Purchase the optional A.G.A. design-certified
manual shutoff valve from your dealer. See ACCESSORY, page 21.
Test all gas piping and connections for leaks after installing or
servicing. Correct all leaks at once.
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.
Make sure external regulator has been installed between propane
supply and heater. See guidelines under CONNECTING TO GAS
SUPPLY, page 9.
