SECTION 2
Installation and Operation
A. To Prepare for Operation
1. Remove all protective material which may have been applied to the heater for shipment.
2. Install optional stack extension, P/N CAH-132.
3. Install output duct, P/N CAH-1015.
4. Open vent on fuel tank.
NOTE
: Two air ducts, 15 feet in length and 12 inches in diameter, connect to the inlet and outlet ends of the
heater and move air from the interior of the shelter, through the heater, and back to the interior of the shelter. In
conditions where the outside ambient temperature is above freezing, only the heated air return duct is used. In this
way, the heater draws unheated air from the outside. Operating the heater without input ducting in warmer
temperatures allows the heater to run cooler, thus preventing safety overheat shutdown. Also follow these
guidelines if the heater shuts down on overheat.
B. Electrical Supply
1. Power source 120 volt, 60 or 50 cycle single phase A.C.
2. When using an extension power cord, make sure it is a three wire cord and of adequate size, as listed in the
following table.
EXTENSION CORD SIZE
LENGTH OF CORD WIRE SIZE (AWG)
100 ft NO. 14
200 ft NO. 12
300 ft NO. 10
400 ft NO. 8
450 ft NO. 6
C. Starting the Heater
1. Open fuel filler and check for an adequate fuel supply.
2. Plug the heater power cord into the grounded power supply outlet. There is no on off switch, the heater will start
immediately.
3. If a thermostat accessory is being used, set the dial to the desired temperature. The heater will start
immediately provided that the surrounding air is cooler than the setting of the dial. The heater will continue to
operate until the temperature of the surrounding air reaches the dial setting. It will then shut down and recycle
when the temperature drops.
D. Stopping the Heater
1. Unplug heater power cord from grounded power supply outlet.
2. If the heater is equipped with a thermostat accessory, turn the dial to
the”No Heat” position.
