D . M ake the 12 V olt D .C . electrical connections following the wiring diagram
illustrated in Figure 8.
If the power supply is to be from a convertor, we recom m end that the converter
system be wired in parallel with the battery. T his will serve two purposes:
1. P rovide a constant voltage supply
2. Filter any A.C . spikes or volt surges
W e recom m end insulated term inals be used for all electrical connections.

D . C heck rating plate and wiring diagram (Figure 9) before proceeding. Install a
fused safety switch or circuit breaker of adequate capacity betwe en 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 m ust be attached to the green nu t in the junction bo x.
C AU TIO N : B efore applying the 120 V AC pow er to the w ater heater junction
box, be sure the sw itch for electric elem ent is in the "O FF" position.

MAINTENANCE

W AR N IN G ! If the user of this appliance fails to m aintain it in the condition
in w hich it w as shipped from the factory or if the appliance is not used
solely for its inte n d ed purpose or if appliance is not m aintained in
acco rdance w ith the instructions in this m anu a l, then the risk of a fire
and/or the production of carbon m onoxide exists w hich can cause
personal injury, property dam age or loss of life.
W AR N IN G : For your safety, all repairs should be perform ed by your dealer
or a qualified service person.
A . M ain B urner: D o not allow the burner to burn with a yellow flam e, because
sooting will occur. (S ee S afety W arnings). If the burner flam e is yellow and has an
erratic pattern, shut unit down and contact a qualified service agency. D o not
continue operating unit with im proper burner flam e. (S ee Figure 11 for correct and
incorrect burner flam e appearance.)
B . P eriodically inspect unit for soot. If soot is present anywhere on water heater,
im m ediately shut unit down and contact your dealer or a qualified service person.
S oot is a sign of incom plete com bustion and m ust be corrected before operating
water heater. Areas to check would include:
1. C heck for an obstruction in burner or the flue box.
2. C heck the screen in the door to see that no foreign m aterial has accum ulated
to prevent flow of com bustion and ventilating air.
3. C heck to be sure there is no flam e present at burner orifice or burner whenever
m ain gas valve is closed. This can be check ed by turning the O FF/O N switch to
the "O FF" position.
C . Frequent check s should be m a d e of the grom m et on the gas inlet to assure
tight seal. (S ee "Mak ing G as C onnections").
D . P eriodically check wiring an d wire connection to be sure wiring is not
dam aged/frayed and tha t a ll term inals and connections are tight and in
com pliance with codes (S ee "Mak ing W ire C onnections").
