Check installation of air thermocouple and that burner head is rotated so flame rod is
on side of burner body as shown in picture above. Apply power by turning on
disconnect. Check that power on terminals 1 and 3 on the electrical panel is between
110 and 120 VAC. If the single-phase voltage is not within this range, check that the
correct secondary tap connections are made on Control Voltage Transformer CT
referring to the
ELECTRICAL SCHEMATIC Drawing No. CA17011C shown in this
manual. Call the factory for assistance.
Gas Train Status -- Observe the state of the gas train here.
If the rotation is wrong, disconnect 3 phase power to the Heater following
OSHA lockout/tag-out procedures before proceeding.
Swapping the positions of two of the 3
Æ
wires at the supply side of the motor contactor
(MC) will reverse the blower motor. After checking the wires a final time for tightness,
reconnect the power.
TIPS
It is better to change the speed of the blower to get close to the desired air
volume than severely gating down the air flow from an over sped blower.
