1)
Pressurize the water system by turning on pump or city
water pressure.
2)
Purge all air from the system by turning on the faucets
until a steady stream of water flows.
3)
Turn on the 12V DC power supply.
4)
Turn on the LP supply at the tank and the manual gas
valve (if installed).The water heater will remain
dormant until a water tap is opened and the heater
senses water flow of at least 0.5 GPM.
5)
Turn on the hot water tap to full open. The heater will
fire up within several seconds and hot water will flow
from the tap in the time it takes to traverse the lines
from the heater to the faucet. (If this is the first usage,
you may have to turn the water on and off several
times to purge the LP gas lines of air. If the heater fails
to light or the lockout lamp (optional) illuminates, turn
the power switch OFF, then ON to reset the ignition
control. After ignition water flow can be reduced cold
water added as desired.
6)
To shut off the water heater, shut off the water. Shut off
power at remote switch or breaker.
7)
Should overheating occur or the gas supply fail to shut
off, turn off the “ON/OFF” power switch.
A Note About “Navy Showers” When Dry Camping
It is recommended to take a shower just like you would at
home. That is, leave the water running through the entire
shower. The hot water system is designed to deliver a
continuous, comfortable flow of hot water and that’s the
way it works best.
Shutting off the shower with the showerhead button
wastes water. Each time this is done, the showerhead
“trickles”, filling the hot water line with cold water. This
cold water has to be purged from the line each time the
showerhead is turned back on. Tests have shown that
this will not save water and sometimes uses more water
than leaving the shower run continuously

Winter Operation and Winterizing Water
This heater is equipped with freeze protection that will
prevent freezing under most conditions. In order for it to
function, 12 VOLT AND GAS SUPPLY MUST REMAIN
TURNED ON. This allows the burner to fire and electric
elements to protect the system. Any freezing of the
water heater or other plumbing components can cause
severe damage that is not covered by warranty.
Winter Traveling Operation:
In some areas all LPG appliances must remain off
when coach is in motion. If this is the case, drain
heater as follows:
1.
Turn off water pump and the power and gas to the
heater. Open the pressure relief valve by lifting the
handle to a 90° position from the normal position.
2. Open at least one hot and cold water tap in the
coach. This should drain the system.
Winterizing Procedure:
Before storing the system for the winter, the plumbing
system must be winterized. This can be done by either
of the following methods:
1. All water should be drained from the system. To do
this, open one tap at a time using compressed air to
purge the system of all water.
2. Recommendations of your coach manufacturer
should be followed. The water system can be filled with
RV, non-toxic anti-freeze. When you see the anti-freeze
coming from the hot water tap, the heater is protected
.
