32. Optional Multiple
Heater Control -
Options CL31 & CL32
The multiple heater control options are designed to per-
mit the control of up to six heaters (one master and five
slave units) with a single thermostat or a time clock and
single/multiple thermostats.
For maximum safety, the multiple control is one in the
low voltage circuit. These multiple heater control op-
tions may not be used with two-stage gas valves.

SERVICE AND MAINTENANCE
WARNING: If you turn off the power supply, turn off the gas. See Hazard Levels, page 2.
3. Blower Models - Clean the blower, the belt guard, the inlet guard,
and motor of all dirt and grease. Check the blower belt for tension
and wear. Replace a worn belt that may fail before the next sched-
uled maintenance check.
4. Clean the heat exchanger both internally and externally.
5. Check the pilot burner and main burners for scale, dust, or lint
accumulation. Clean as needed.
6. Check the vent system for soundness. Replace any parts that do
not appear sound.
7. Check the wiring for any damaged wire. Replace damaged wiring.
(See Paragraph 12 for replacement wiring requirements.)
This unit will operate with a minimum of maintenance. To ensure
long life and satisfactory performance, a heater that is operated under
normal conditions should be inspected and cleaned at the start of each
heating season. If the heater is operating in an area where an unusual
amount of dust or soot or other impurities are present in the air, more
frequent maintenance is recommended.
The following procedures should be carried out at least annually (See
Paragraphs 33-42 for specific instructions.):
1. Clean all dirt and grease from the primary and secondary combus-
tion air openings.
2. Fan Models - Clean the fan blade, fan guard, and motor.
