– Gas rear connection
Risk of explosion when using flexible gas
hoses with a gas rear connection.
• Flexible gas hoses can leak due to the high
temperatures in the appliance.
• You must use rigid metal 3/8 in. pipes
(corresponds to 1/2 in. (12.7 mm) outside
diameter) for a gas rear connection.
Truma offers a rear installation gas connection
kit (part no. 77000-37500) if installation from the
back of the appliance is required.

Preparing the water connection
All water connections on the appliance are
1/2 in.NPT male connections.
• Use only pressure pumps in the water
system, not immersion pumps, as air
in the water system could cause mal-
functions.
• The network of lines must be planned
before installation (refer to “Connec-
tion diagrams” on page31).
• Keep the length of the water pipes as
short as possible.
• Because of the risk of frost, install
water pipes only in adequately heated
areas of the RV.
• Avoid thermal bridges.
• Install water pipes in a rising direction
so that air in the pipes can escape.
• For AquaGo comfort plus
protect the circulation line against heat
loss with sufficient insulation material.
• Use a suitable connector with a seal for con-
necting the water to the appliance.
• Use of flexible water hoses of at least
1/2 in.diameter is preferred.
• Make sure that all water hoses are installed
without kinks.
• Make sure that the water connections from
the vehicle are in place before installing the
appliance.
