The water heater installed is typically a 10- or 25-gallon unit. Dependant upon the model installed, the water heater can be gas, gas/electric or electric. For specific water heater instructions, please consult the Owner’s Manual provided by the manufacturer. Ensure the water heater is filled prior to turning on the power and/or operating, since this will result in the burnout of the element.
Care & Maintenance
Proper maintenance of the water heater relies on inspection and awareness. (Full maintenance requirements are listed within the manufacturer’s user manual.) A qualified technician should do any repairs that are required. On gas heaters, if soot is present anywhere, immediately shut down the unit and contact a qualified service technician. Soot is a sign of incomplete combustion and must be corrected before operating the water heater.
Pressure Relief Valve – Weeping or Dripping
The water heater is equipped with a relief valve designed to open when the water temperature is too high or excessive pressure has built up. In these circumstances, the relief valve will open and water will drip from the valve. The valve will close automatically once the situation corrects itself. If dripping is continuous, it would indicate a malfunctioning or defective valve.
Draining for Non-Use or Winterization
When not using for long periods or storing for the winter months, the water heater must be drained to avoid damage by freezing during the winter months and/or deterioration from mineral content in the water supply.
To drain the tank:
- Turn off power to the water heater at the switch or main breaker, on electric or gas/electric units.
- Shut off the gas supply.
- Open all fixtures, both hot and cold, throughout the unit.
- Place the by-pass valve (if equipped) in the “by-pass” position.
- Remove/open the exterior access door to the water heater.
- On 10 gallon RV models, remove the anode rod from the tank. Water will drain out of the tank.
- On 25 gallon water heaters without an outside door and anode tube, a garden hose must be attached to the shut-off valve, located at the bottom of the water heater, to drain the water from the tank.
