agency.
NOTE: It is important that once the unit has returned to lower elevation (below
4,500 feet), this high altitude deration and pilot adjustments (if equipped) be
reversed for proper operation of the unit.
MAKING ELECTRICAL CONNECTIONS
12 VOLTS D.C.
A. Refer to Figure 2 for location of D.C. junction box SW6DEL.
B. The electrical connections must be made in accordance with local codes and
regulations. In the absence of local codes and regulations, refer to the latest
edition of the National Electrical Code NFPA 70.
In Canada, the electrical installation should conform with CSA standard CAN/
CSA Z240.6.2-08/C22.2 No. 148-08 Electrical Requirements for Recreational
Vehicles and CSA C22.1 Canadian Electrical Code Part 1 when installing the unit
in recreational vehicles and mobile homes respectively.
C. Make the 12 Volt D.C. electrical connections following the wiring diagram
illustrated in Figure 6.
If the power supply is to be from a converter, we recommend that the converter
system be wired in parallel with the battery. This will serve two purposes:
1. Provide a constant voltage supply
2. Filter any A.C. spikes or volt surges
We recommend insulated terminals be used for all electrical connections.
12 V.D.C. ONLY
IF ANY OF THE ORIGINAL WIRE AS SUPPLIED WITH THE WATER
HEATER MUST BE REPLACED, IT MUST BE REPLACED WITH 18 GA.,
105°C WIRE OR IT'S EQUIVALENT.

120 VOLTS A.C.
A. Refer to Figure 2 for location of A.C. junction box.
B. The electrical connections must be made in accordance with local codes and
regulations. In the absence of local codes and regulations, refer to the latest
edition of the National Electrical Code NFPA 70.
In Canada, the electrical installation should conform with CSA standard CAN/
CSA Z240.6.2-08/C22.2 No. 148-08. Electrical requirements for Recreational
Vehicles and CSA C22.1 Canadian Electrical Code Part 1 when installing the
unit in recreational vehicles and mobile homes respectively.
C. Check rating plate and wiring diagram (Figure 7) before proceeding. Install a
fused safety switch or circuit breaker of adequate capacity between heater and
electrical power source. Attach the black and white wires from the fused switch
or breaker to corresponding colored wires in heater junction box. A green wire
from a well grounded source must be attached to the green nut in the junction
box.
CAUTION: Before applying the 120 VAC power to the water heater junction
box, be sure the switch for electric element is in the "OFF" position.
WARNING! Before the switch for the electric element is turned to the
"ON" position, the water heater tank must be filled with water. See
"Safety Warnings".

WARNING! If the user of this appliance fails to maintain it in the
condition in which it was shipped from the factory or if the appliance is
not used solely for its intended purpose or if appliance is not maintained
in accordance with the instructions in this manual, then the risk of a
fire and/or the production of carbon monoxide exists which can cause
personal injury, property damage or loss of life.
WARNING: For your safety, all repairs should be performed by your
dealer or a qualified service person.
A. Main Burner: Do not allow the burner to burn with a yellow flame, because
sooting will occur. (See Safety Warnings). If the burner flame is yellow and has
an erratic pattern, shut unit down and contact a qualified service agency. Do not
continue operating unit with improper burner flame. (See Figure 8 for correct and
incorrect burner flame appearance.)
B. Periodically inspect unit for soot. If soot is present anywhere on water heater,
immediately shut unit down and contact your dealer or a qualified service person.
Soot is a sign of incomplete combustion and must be corrected before operating
water heater. Areas to check would include:
BK
1. Check for an obstruction in burner or the flue box.
2. Check the screen in the door to see that no foreign material has accumulated
to prevent flow of combustion and ventilating air.
3. Check to be sure there is no flame present at burner orifice or burner
whenever main gas valve is closed. This can be checked by turning the OFF/ON
switch to the "OFF" position.
C. Frequent checks should be made of the grommet on the gas inlet to assure
tight seal. (See "Making Gas Connections").
D. Periodically check wiring and wire connection to be sure wiring is not damaged/
frayed and that all terminals and connections are tight and in compliance with
codes (See "Making Wire Connections").
