Flame Appearance

REFER TO THE OPERATING INSTRUCTIONS
LOCATED AT THE BACK OF THIS MANUAL
BEFORE LIGHTING THE HEATER TO OBSERVE
THE FLAMES.
Flames from the pilot, front and rear burner
should be visually checked as soon as the
heater is installed. In addition a periodic visual
check of the flames should be made. The pilot
flame should always be present when the heater
is in operation and should just envelope the tip
of the thermocouple ( Figure 13 ).
WARNING: NO ADJUSTMENTS ARE TO
BE MADE TO THE ODS PILOT SYSTEM.
TAMPERING WITH THIS SYSTEM CAN
BE EXTREMELY HAZARDOUS.
Figure 13
An incorrect pilot flame is shown in Figure 14 .
This pilot flame will cause the thermocouple to
cool. When the thermocouple cools, the heater
will shut off. If pilot flame pattern is incorrect,
or if heater shuts off, contact your service
representative.
NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.
