Servicing Or Filling; Lp Gas Container Overfill - Jayco SEISMIC 2021 Owner's Manual

Section 7: Fuel & Propane System
NOTE:Tanks are to be installed, fueled and maintained in accordance
to State and Local codes, rules, regulations or laws.
Propane is a true gas compressed into a liquid form. As the fuel is released from the con-
tainer, it changes to vapor which is then used for the opera-
tion of the appliances. Propane will not run through the
appliances in the liquid state.
Propane expands 1½ percent for every ten degrees of in-
crease in temperature. It is imperative to leave sufficient
space inside the container to allow for natural expansion of
gas during warmer weather.
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 createto 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.
This propane label should be kept permanently affixed to
your RV.

Servicing or Filling

Have the recreation vehicle checked for leaks at the connections
on the propane system soon after the purchase and the initial
filling of each propane cylinder.
When you have a new cylinder filled for the first time, make
sure your propane supplier purges 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 the RV and only the qualified propane service 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 OVERFILLED. This "shut
off for re-fueling" label should be kept permanently affixed to
your RV.
The position of the propane container(s) and the hoses are critical to proper operation and
propane flow. Follow these instructions to make sure your propane container(s) are con-
nected properly.

LP Gas Container Overfill

Never allow your propane tank to be filled above the maximum safe level as indicated by the
fixed liquid level gauge. Do not allow the visible gauge to be used for filling. 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.
The propane piping system is designed for use with propane only. Do not connect
natural gas to this system.
