installation procedure
Drain water hose
Drill a hole through flooring. To avoid damage to the hose, the hole must be positioned so that the hose doesn’t touch the boiler casing. Seal around the hose that goes through the drilled hole and ensure that it does not kink when run through the floor. Check to make sure that the supplied hose is long enough in order for the water to drain outside of the vehicle. If not, the installer will have to supply the extra length of hose.
Connections
Gas connection
Hook up to the gas supply line is accomplished at the manual gas valve, which is furnished with a 3/8” SAE (UNF 5/8”

6! warning
EXPLOSION HAZARD. Never use an open flame to check for gas leaks. Failure to heed this warning could cause an explosion resulting in death or severe personal injury.
The gas supply system must incorporate a pressure regulator to maintain a supply pressure of not more than 11 inches water column. When testing the gas supply system at test pressures:
•> 1/2 psi - the refrigerator and its individual shutoff valve must be disconnected from the gas supply piping system.
•≤ 1/2 psi - the appliance must be isolated from the gas supply piping system by closing its individual manual shut- off valve.
If detailed instructions on the installation and connection to the gas supply are required, please contact your dealer or distributor.
Testing LP gas safety shut off
The gas safety shut off must be tested after the refrigerator is connected to LP gas supply.

To test the gas safety shut off, follow these steps:
1.Start the refrigerator. Switch to GAS mode.
2.Check that the gas flame is lit and the GAS mode indicator lamp is on.
3.Close the manual gas shutoff valve at the back of the refrigerator.
4.Wait for approx. 6 minutes. The CHECK indicator lamp should be lit and the GAS mode indicator lamp should be off.
5.Remove the protection cover.
6.Open the manual gas shutoff valve. Do not change any button positions on the control panel.
7.Apply a non corrosive commercial bubble solution to the burner jet orifice. No bubbles should appear at the opening of the burner jet orifice. The presence of bubbles indicates a defective gas safety shutoff, and service is required.
8.If no bubbles are present at the burner jet orifice, rinse it with fresh water. Be careful not to damage the burner jet orifice.
