6. Using the old pilot tube as a guide, bend the new pilot tube
to match the old one. Make only the bends closest to the
pilot before going to the next step.
NOTE: Skip this step if you are reusing the existing
pilot tube.
7. Reconnect the pilot tube and tighten the nut securing it to
the new pilot assembly. To prevent any bending of the pilot
bracket, use pliers to hold the pilot assembly bracket while
tightening the pilot nut. IMPORTANT: Keep the pilot orifice in
the pilot when making the connection. DO NOT operate the
water heater without the pilot orifice installed.

(flame arrestor), use a vacuum, compressed air, or a soft bristle
brush to remove it. NOTE: If unable to inspect or clean the flame
trap from underneath, follow the "Cleaning the Combustion
Chamber and Flame Trap" section instructions.
