Water Control Valve

The water heater is equipped with a water flow control valve,
set from the factory at MAX flow. The valve will reduce the
water flow and capacity through the water heater to improve
water heating performance.

Cleaning and Maintenance

WARNING
Burn or Scald Hazard
● NEVER perform work while the water heater is
operating.
● NEVER perform work without turning the Electrical and
LP gas supply off.
● NEVER perform work when the appliance is hot.
● NEVER actuate the pressure relief valve as long as the
appliance is still hot.
● Never actuate the Drain Plug as long as the appliance is
under water pressure and/or is still hot.
CAUTION
Always wear protective gear such as gloves,
eyewear and clothing to avoid injuries during
installation and servicing of the product.

Storage and Transit

Anytime the RV is not intended to be used, it is considered to
be in storage or transit. To prepare the water heater, follow
the below steps:
1. Turn off gas supply.
2. Turn off water heater main switch.
3. Drain water out of the system and water heater by
removing the filter cover and drain plug (Fig. 31)
Under extreme conditions, it may be necessary to adjust the
valve accordingly:
● Cold water inlet conditions approximately less than 45°F
(7°C)
● Higher water inlet pressures >65 PSI.
To operate (Fig. 30):
● Reduce water flow: Rotate knob clockwise until a solid
stop.
● Increase water flow: Rotate knob counter clockwise until
a solid stop.
