6. User Instructions
Before turning on gas, check main supply valve to
be sure it is open (Fig. 3). 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
counter-clockwise 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.
6.1 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 the on/off
switch is activated. If an external thermostat is
to be used (See Component & Wiring
Diagram), the heater will operate only when
power is supplied, the on/off switch is
activated, and the thermostat indicates a call
for heat.
6.2 Starting 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
counter-clockwise 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 qualified gas
heater service personnel.
Follow these 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 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 is not in the PILOT
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 to the ON
position.
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 to 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.
6.3 Shutting OFF Heater
Shut off main gas supply valve, close ball valve, and disconnect electrical power.
CAUTION!
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 Section 2 'Specifications and Requirements'.
Both installer and operator must ensure that the building’s ventilation rate never drops below the
noted limits.

Part No. 4801-1020 Rev 2-2015 Super-Saver XL 250 Heater –120 Volt, 60Hz, ETL Page 11 of 22
6.4 Variable Heat Output Adjustment
1. Some models of propane (LP) gas or natural gas heaters have a throttle valve located between the
gas control valve and gas manifold assemblies which is used for varying the heat output. THIS IS
NOT A MANUAL GAS CUT OFF VALVE.
2. The throttle valve 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 5. The throttle valve 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 6.

10. Pipe Sizing Guidelines
10.1 Calculating HVR & ELOP
1. Using a system schematic, label each piping
section of the system starting at the meter or
regulator. A different pipe section starts
where the gas demand of the system
changes, usually at a junction.
2. Determine the Heating Value Required
(HVR) in BTUH (BTU's per hour) for each
section of pipe.
HVR = (no. heaters supplied by pipe
section) X (heat output per heater)
3. Determine the Equivalent Length Of Pipe (ELOP)
required for sufficient gas service.
ELOP = (length from meter to most remote heater)
+ (Minor loss equivalents of the system)
IMPORTANT: Use the ELOP value from this
equation for size determination of all pipe sections.
4. Use the ELOP value from step 3, and the HVR of
each pipe section to determine the required pipe size
for either natural gas (NG) (Table 1) or liquid propane
(LP) (Table 2) from the table 'Maximum Capacity Of
Pipe'.
10.2 Directions for Reading Pipe Size from Tables:
EXAMPLE: Four 40,000 BTUH (12 kW) heaters will be installed on the gas pipe line in the 'Arbitrary Piping System'
diagram below. NOTE: Values given in English and Metric equivalent units.
1. Determine the HVR value for each pipe section of the system.

2. Determine the ELOP. Length from meter to most remote heater = length from a to e (or g) = 100ft (30m) + 25ft
(8 m) = 125ft (38 m) Minor loss equivalents from Table 1 = 1 gate valve x 2ft/valve (1 m/valve) + 3 tees x 11
ft/tee (4 m/tee) =35ft (13 m). Calculated ELOP = 125ft (38 m) + 35ft (13 m) = 160 ft (51 m) Tabulated ELOP =
200ft (60 m) Round up to the nearest table value.
3. In the appropriate table, NG (Table 2) or LP (Table 3), select the column showing the ELOP or the next longer
length, if the table does not give the exact length. Use this column to compare table values to the HVR values.
Use the Natural Gas table (Table 2) in this
example. From step 2, ELOP = 200ft (60 m)
Locate the column labeled 200ft (60 m) in Table 2.
4. Select a pipe section and read down the ELOP
column to find the maximum gas capacity that
matches the HVR for that particular pipe section.
If the exact value is not listed, choose the next
larger value in the column. In this example, start
with pipe section c-e. For pipe section c-e, HVR =
40,000 BTUH (12 kW). From Table 2, column 200
ft, 40 (12) is not listed (NOTE: The table values
are in thousands of BTUH's). The next larger
value of 72 (21) is read from the table,
corresponding to 72,000 BTUH (21 kW).
5. Follow the row leftward until you reach the
columns labeled 'Internal Diameter' and 'Nominal
pipe size'. Read the pipe size for the particular
pipe section. For example, for pipe section c-e,
the pipe size is ¾ inch (0.824 in.) (19.1 mm).
Repeat for each pipe section.
