Water Heaters
Direct Spark Ignition Water Heaters
Before operating the water heater, the tank must be filled with water.
Do not store any combustible materials or liquids near or adjacent to the water heater.
How to Operate a Water Heater on LP
1. Make sure the water heater is full of water and is not bypassed.
2. Turn on the gas valve on the LP tank.
3. Prior to activating the water heater, smell for any gas odors, as any present fumes may create a spark and
flame.
4. Turn on the switch to light the burner. The control board will attempt three times to ignite the LP at the burner.
After three attempts, the red indicator light at the switch will illuminate.
5. If lockout occurs, turn the switch off, and wait several seconds before turning it back on. It will make three more
attempts to light the burner.
6. On initial startup, it may take a few cycles to purge the LP lines.
7. If the water heater continually fails to light, refer to the Operator's Manual for your specific water heater.
Propane Distribution Lines
The primary gas supply manifold is a black steel pipe running the length of the unit. Most secondary lines
leading to the gas appliances are made of copper tubing with flare fittings. If any of these lines rupture, do not
attempt to splice them. Always run a new line. Gas distribution work must be performed by an authorized
service technician. When removing or servicing any gas appliance, close the main gas valve on the propane
tank to prevent dangerous gas leakage that could result in an explosion and possible serious injury. If a gas
leak is suspected, have the system inspected and repaired by a qualified service technician as soon as
possible.
How to Operate a Water Heater with an Electric Element on 120 Volt Power
1. Check for the proper voltage supply (120 Volts).
2. Make sure the water heater is full of water and is not bypassed.
3. Turn on the switch to the electric element. The water heater will control the temperature.
4. If the water heater fails to heat, refer to the Operator's Manual for your specific water heater.

Pressure Relief Valve

The temperature and pressure relief valve is located on the exterior of the water heater. It is designed to open if the
temperature of the water within the heater reaches 210° F, or if the water pressure in the heater reaches 150 pounds.
Recreational vehicle water systems are closed systems, and during the water heating cycle the pressure build-up in the
water system may reach 150 pounds. When this pressure is reached, the pressure relief valve will open and water will
drip from the valve. This dripping will continue until the pressure is reduced below 150 pounds, and the valve closes.
This condition is normal and does not indicate a defective relief valve.
