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.

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 the main-switch located behind the access door
of the water heater unit (Refer to Fig. 16).
3. Drain water out of the system and water heater by
removing the filter cover and drain plug (Fig. 37)

4. If freezing conditions could occur, then winterize
according to "Winterizing Water Heater".
Winterizing Water Heater
CAUTION
Product damage due to frost condition
In frost conditions, ambient temperatures below 39°F (4°C),
there is a risk that water in pipes, faucets and appliance
could freeze. This can cause considerable damage.
Follow the instructions provided by the RV coach
manufacturer for winterizing your water system.
Supplement the following important water heater instructions
when completing any winterizing steps:

Compressed Air:
● DO NOT exceed 50PSI in the water heater when blowing
out the system.
● While completing the blow out process for the entire
water system, take time to isolate the water heater by
closing all drain plugs and faucets and only open the
water heater drain plug. This ensures maximum pressure
and flow is isolated through the water heater for complete
evacuation.
Anti-freeze:
● Use a non-toxic antifreeze recommended by the RV
coach manufacturer.
● Anti-freeze can be used directly in the water heater, plan
for an additional 1L to fill the system.
Optional: A bypass valve can be installed/used to bypass
filling the water heater with antifreeze. The water heater
MUST be evacuated with compressed air (see steps
above) before bypassing.
Next Season:
● Thoroughly flush the water heater and system with clean
drinking water through the hot and cold side before using.
Drain water several times out of the water heater drain
plug. Sanitize the water system per the recommendations
of your coach manufacturer.
Routine Inspection
Routine inspection is critical for maintaining proper operation
of your appliance. Unless specified, review the following
items yearly or before each season:
1. Inspect the gas system and installation every two years,
or otherwise specified by your RV coach manufacturer, by
a qualified personnel.
2. Inspect for cracks, separation, peeling of seals to the RV
wall. Remove and re-seal as necessary (caulking or tape)
between the side wall and the door of the water heater
and ensure that the unit is solidly mounted to the vehicle.
3. Verify that the air inlet openings (louvers) are completely
open and clear of any debris including mud, leaves, twigs,
insects, etc... Remove all obstructions to allow full air flow.
4. Before actively using your vehicle, pre-inspect that the
air inlet openings (louvers) are completely open and clear
of any debris including mud, leaves, twigs, insects, etc...
Remove all obstructions to allow full air flow.
5. Before actively using the vehicle, verify that the exhaust
tube and screen are completely clear of obstructions
including: mud, leaves, twigs, insects, nest, etc. Clean by
gently breaking up and using a vacuum to clear it. Use
only water and apply gently from a spray bottle, NEVER
spray directly with high pressure. Run the appliance to dry
any moisture and blow out loose debris. The use of any
after-market protective screen is prohibited and will void
the warranty.
6. Before actively using the vehicle, open the door and verify
that no debris or extraneous combustible materials are
present anywhere (especially in the area of the burner
