Grand Design Imagine - Servicing or Filling; LP Gas Container Overfill; Installing the Propane Cylinders

Propane Systems
The main shut off valve must be kept closed at all times un-
less you are using the propane system or filling the propane
cylinder. When the cylinder is disconnected from the hose,
install the valve cover that is attached to the container. Close
the propane cylinder main shut off valve by hand tightening
only. Use of tools creates a potential to over tighten the valve
(damaging the interior seals on the cylinder valve seat). If this
type of damage occurs, the cylinder will not close properly.
Servicing or lling
Have the RV checked for leaks at the connections on the
propane system soon after the purchase and the initial fill-
ing of each propane cylinder. When you have a new cylinder
filled for the first time, make sure your propane supplier purg-
es your new cylinder of trapped air. Otherwise, an improper
mixture of gas and air will make it impossible to light your
propane appliances.
No one should be inside and only the qualified propane ser-
vice technician should be near the RV while the propane tank
is being filled. The new propane container must be carefully
purged for best performance and must NEVER BE OVER-
FILLED. The position of the propane container(s) and the
hoses are critical to proper operation and propane flow. Fol-
low these instructions to make sure your propane container(s)
are connected properly.
LP gas container overll
Never allow your propane cylinder to be filled above the max-
imum safe level. Overfilling the propane container above the
liquid capacity indicated on the container, could allow liquid
propane to enter the system that is designed for vapor only
creating a hazardous condition.
Installing the propane cylinders
1. Make sure all the RV appliances are shut off.
2. Make sure each LP cylinder shut-off valve is closed.
3. Place the LP cylinders on the LP cylinder brackets or
LP tray (if so equipped) located on the trailer a-frame,
and secure them.
4. The two 3/8” low-pressure pigtail hoses should be
attached - one to each side of the auto changeover
regulator.
