Safety behavior and practices
• Installation and service must be performed
by an authorized Truma-trained installer.
Improper installation, alteration, service or
maintenance can cause property damage,
personal injury or loss of life.
– Do not attempt installation as a Do-it-Your-
self project.
• Install in recreational vehicles (RVs) only.
• Improper installation may result in a risk of
explosion.
– Read and follow the installation
instructions.
– Use the supplied parts.
• Switch off the vehicle’s on-board power sup-
ply (12 VDC and 120 VAC) during installation
and when connecting the Combi furnace.
• Close the vehicle’s gas supply during in-
stallation and when connecting the Combi
furnace.
• Always wear protective gloves to avoid inju-
ries from sharp edges during installation and
maintenance work.
• Always protect your eyes from injury. Wear
protective eyewear whenever installing or
handling the Combi furnace.
• Always use the recessed grips (Fig. 2 – 19 and
Fig. 3 – 19) to grab, lift or handle the Combi
furnace. Never lift or grab the furnace by any
of its delicate exterior components.
• Make sure that all combustion air is supplied
from outside the RV. Never supply air for
combustion from occupied spaces.
• Provide adequate combustion and ven-
tilation air to the furnace space as speci-
fied in”Installation position: wall cowl” on
page 11 and the following and in “Cir-

• Combustion products must be discharged
outdoors. Connect this furnace to an ap-
proved venting system only, as speci-
fied in”Installation position: wall cowl”
on page 11 and the following of these
instructions.
• Always install the Combi furnace to operate
within the furnace’s intended temperature-
rise range with a duct system which has an
external static pressure within the allowable
range, as specified in”Warm air distribution”
on page 15 and the following of these in-
structions (see furnace rating plate).
• Any alteration to the furnace or its controls
can cause unforeseen serious hazards.
