L.P. Gas Water Heater Installation
This section describes how to install the Water Heater
and control switch. Please consider the following
directives prior to beginning installation:
• This appliance must be installed by a qualified
professional installer.
• The water heater tank must be supported at the same
level as the bottom of the sidewall cutout. Provide
adequate clearance at the rear of the unit for easy
service access to the water connections.
• If the appliance is installed where a connection or
tank leakage can damage an adjacent area, install a
drain pan (which can be drained outside of the RV)
under the Water Heater.
• To install the Water Heater on carpeting, install
the Water Heater onto a metal or wood panel that
extends at least 3 in. (7.62 cm) beyond the total width
and depth of the Water Heater.
