3. Installation
Hanging the Heater
Chain Suspension
Mount the heater with chain hooks and chains so that the back of the heater is at least 12" (305 mm) from
the ceiling and wall. The heater must be a minimum of 20" (500 mm) from floor, and located so that
livestock and combustible materials are unable to come in contact with heater or within 10' (3 meters) of

Cable Suspension
If frequent height adjustment is required, use cables and pulleys. Main line cable would be connected to
a winch.
Directions for Leveling
Adjust cables or chains as required to level the heater. Use a carpenter’s level to check that the heater
is level.
Installing the Dual-Flare Duct
Fold Dual-Flare duct (1) to shape as shown in Figure 3A. Install Dual-Flare duct to heater exhaust as
shown with sheet metal screws (3) provided. This provides a multi-directional heat flow (2) that may be set
by bending flaps.
Figure 3A
Connecting the Gas Supply
For gas connection, attach the regulator (2) to the High Pressure Line (3) at the outside of the building as
shown in Figure 3B. Connect flexible hose (1) to low pressure end of the regulator with special brass
coupling. Refer to table on Page 13 for LP and natural gas requirements.

4. User Instructions
Before turning ON gas, check main supply valve to be sure it is open. (See Figure 4A.) Be sure to check
all connections for leaks with a Gas Leak Testing solution. (soap and water work well.) Check to see if gas
valve knob is in the ON position. If not, turn counterclockwise until knob “clicks” into the ON position.
(This may not apply to all units.) Turn ON gas by turning the ball valve handle into vertical position.
Figure 4A
Connecting Electrical Power
Make sure a circuit breaker or similar cutoff device is provided to permit disconnection of
electrical power to heater for service and cleaning. All electrical work should be performed by a
certified electrician. If no adjustments are made, the heater will operate every time power is supplied and
theON/OFFswitch isactivated.Ifan externalthermostat istobeused(see componentandwiring diagram
on Page 19), the heater will operate only when power is supplied, the ON/OFF switch is activated, and the
thermostat indicates a call for heat.
Start-Up
Before turning ON gas, verify that the main supply valve is open. Check all connections for leaks with a
soap and water gas leak testing solution. Verify the gas valve knob is in the ON position. If not, turn
counterclockwise until knob “clicks” into the ON position. (This may not apply to all units.) Turn ON gas by
turning ball valve handle into vertical position.
IMPORTANT: Heater installation must be performed by a qualified gas heater service personnel.
Follow the below steps to light the pilot and position the gas valve control for use.
NOTE: Do not supply power to the heater during this start-up. Supplying power to the heater at this stage
could cause the blower to start which will make lighting the pilot difficult.
1. Open all manual gas supply valves and check all connections for gas leaks.
2. Position the gas shut off valve (1) to the pilot position.
3. Fully depress the red pilot button, located on the gas valve, while applying a flame to the pilot light
burner. If the red pilot button cannot be depressed the gas shut off knob (1) is not in the PILOT (3)
position.
4. After the pilot light is lit, keep the red pilot button depressed for approximately 30 seconds to heat the
thermocouple.

5. With the pilot light lit and once the thermocouple is warmed, move the gas shut off knob (1) to the
ON position (2).
Figure 4B
6. Supply power to the heater by either plugging the power cord into an approved outlet, a piggy back
thermostat, or moving the thermostat to a desired temperature above room temperature if the heater
has been wired with this type of thermostat.
7. During the first start-up for a new heater installation or if the heater gas has been shut off, it may take
longer to purge the air from the lines before the pilot will light.
8. Once the heater is running for the first time, verify the inlet and manifold pressures match those on
the Danger label (listed under Acceptable Pressures) on the outside of the heater. This should be
done only by a qualified gas installer. Operating the heater at a pressure too high or too low will
adversely affect the operation of the heater and will void all warranties.
NOTE: If the pilot light extinguishes, allow a five minute complete shut off period before attempting to
relight the pilot.
Shutting OFF Heater
Shut off main gas supply valve, close ball valve, and disconnect electrical power.

Limiting Excess Carbon Dioxide (CO2 )
In order to prevent hazardous accumulation of CO2 gases, the heater must
operate ONLY in a properly ventilated room.
Ventilation requirements are given in Specifications and Requirements Section
on Page 13.
Both installer and operator must ensure that the building’s ventilation rate never
drops below the noted limits.

4. User Instructions
4801-1020 Super-Saver XLTM Heater 17
Variable Heat Output Adjustment
1. Some models of propane (LP) gas or natural gas heaters have a throttle valve (1) located between
the gas control valve (2) and gas manifold assemblies (3) which is used for varying the heat output.
NOTE: THIS IS NOT A MANUAL GAS CUT OFF VALVE.
2. The throttle valve (1) can be adjusted to deliver either minimum heat or maximum heat. When the
throttle valve handle is parallel to the gas flow, the valve is completely open to deliver maximum heat
output. Refer to Figure 4C. The throttle valve (1) may be adjusted to minimum heat output by turning
the handle 90° to the gas flow or any position between the maximum and minimum settings.
Refer to Figure 4D.

5. Maintenance
1.The appliance area should be kept clear and free from combustible materials, gasoline and other
flammable vapors, and liquids.
2. The flow of combustion and ventilation air must not be obstructed.
3. Your Super Saver XLTM Heater should be inspected before each use, and at least annually by a
qualified service person.
4.The hoseshould bevisually inspectedpriortoeachuseof theheater. Ifit isevident thereis excessive
abrasion or wear or the hose is cut, it must be replaced prior to the heater being put into operation.
The replacement hose assembly shall be that specified by the manufacturer. (Refer to parts list on
on Pages 25-30.)
5. Inspect heater and gas connections periodically for gas leaks with an approved gas leak testing
solution; applying a soapy water mixture to gas connections works well. Bubble formation indicates
a leak.
6. Keep heater clean at all times.
a. Open doors and blow out dust with high pressure air hose. Be sure interior of burner and flared
end are kept clean.
b. Burner orifice and pilot ignition assembly must be kept clean and free of carbon build-up.
c. Check blower wheel regularly for dust accumulation and clean periodically for maximum airflow.
d. Thermostat coils must be kept clean to assure proper temperature control.
e. Pilot assembly must be cool before wash-down. Do not operate heater for one hour following
wash-down.
DISCLAIMER
This appliance rating is based on the use of ANSI LC-2 test gases including LP (2500 BTU/ft3,
93.15 MJ/m3) and natural gas (1075 BTU/ft3, 40 MJ/m3). Cumberland makes no guarantees regarding
the proper operation of this appliance when these conditions are not met.
