GAS SUPPLY CONNECTIONS
Warning
Only connect this water heater to the type of gas listed on the rating plate. Any attempt to adapt the
water heater for use with a different type of gas could casue hazardous operating conditions.
• This water heater is designed for use with liquid propane (LP) gas only.
• The gas line must be composed of an approved gas piping material.
• Gas pressure to the valve inlet must not exceed 13" w.c. for the LP gas supply.
Leak Testing
• The water heater and its gas connection must be leak tested at normal operating pressure before placing
the appliance in operation.
• Turn ON the main gas supply to the RV at the LP gas tanks and check for leaks by applying a soapy water
mixture on all gas fittings, including the factory connections. Presence of bubbles indicate a gas leak, which
must be corrected before completing the installation.
Warning
Never use an open flame to test for gas leaks, as property damage, personal injury, or death could result.
The maximum inlet gas pressure must not exceed the value specified by the manufacturer and the
minimum value listed is for the purpose of input adjustment.
Installing the Gas Connection
1. Route the 3/8" flared LP gas supply line through the opening in the water heater front case.
Note: it may be necessary to remove the rubber grommet, make the gas connection, then reinstall the
grommet.
2. Connect the 3/8" flared fitting to gas valve located on the water heater. When making this gas
connection, hold the gas fitting on the valve with a wrench while tightening the flare nut.
3. If necessary, reinstall the rubber grommet at the gas line opening. It is important for this grommet to
have an air tight seal to prevent moisture or flue gas products from venting through the opening. It is
recommended to caulk around this area after completing the gas line installation to ensure an air tight
seal.
Route the gas supply line
through water heater opening.
