Securing the furnace
Risk of explosion!
An improperly secured Combi furnace can be-
come dislodged in an RV accident and the gas
line can become disconnected.
• The floor or false floor must bear the load
of a secured furnace. Contact the Truma
Service Center on 1-855-558-7862 if you
are unsure whether the floor can bear the
load of the furnace.
• Use the supplied or equivalent screws
(Fig. 5 – 3).
• DO NOT use screws with a smaller core di-
ameter under any circumstances.
1. Screw both aluminum frame feet (Fig. 5 – 1)
to the floor or false floor.
2. Screw at least one plastic frame foot
(Fig. 5 – 2) to the floor or false floor.
