Placing the heating system in operation
RISK TO LIFE
due to poisoning by leaking gas.
If the red reset button does not pop up
WARNING!
when you release it, STOP.
Close gas shut-off immediately to
prevent gas from leaking.
Contact your service technician or LP
gas supplier immediately and have the
fault repaired.
If the pilot burner continues to go out
after several attempts, turn the
ON/OFF button on the gas valve to
OFF immediately to prevent gas from
leaking.
41. Check pilot gas line for leaks with soap solution. If no
leaks are found, continue with step 43. If leaks have
been found, switch ON/OFF switch on gas valve
( Fig. 35, page 36) clockwise to the OFF position.
42. Seal leaks. Repeat steps 1 and 2 (regardless of the
control in use).
Caution:
With aquastat control continue with steps 3 and 4,
with the Logamatic 2107 continue with steps 5
and 6.
Then repeat steps 35 to 41 regardless of the control
in use.
43. Observe pilot flame through the sight glass
( Fig. 36) in the burner housing.
44. The pilot flame must surround the thermal element
3/8 to 1/2 inch. If this is the case continue with
step 48.
45. If the pilot flame is too small or too large, the
pressure for the pilot burner must be adjusted with
the corresponding adjustment screw.
USER NOTE
The adjustment screw is behind the pilot
burner pressure adjustment safety screw
( Fig. 35, page 36).
46. Remove safety screw for pilot burner pressure
setting ( Fig. 37, page 38). Turn the inner
adjustment screw clockwise to reduce the pilot flame
and counterclockwise to enlarge the pilot flame.
We reserve the right to make any changes due to technical modifications.
