noncorrosive leak detection fluid to gas
joints. Bubbles forming show a leak.
4.. Correct.all.leaks.at.once.
TESTING BURNER FOR LEAKS
1. Generously apply noncorrosive leak
detection fluid to all connections.
WARNING: Never check for
gas leaks with open flame.
2. Light burner with shutoff valve no more
than. half. open. and. holding. a. match.
slightly. in. front. of. pan. (see.
Lighting In-
structions
, page 10).
3. Inspect all connections for bubbles, raw
gas odor, or flame from any area other than
burner (leaks). If leaks are detected, shut
off gas valve immediately. Tighten, or reas

semble loose connection(s) using pipe joint
compound.until.burner.system.is.leak.free.
4. When burner is tested and leak free, ob
-
serve individual tongues of flame on burner.
Make.sure.all.ports.are.clear.and.producing.
flame evenly across burner. If any ports
appear blocked, clear by removing burner
