Opening the Truma pressure relief/drain valve

NOTE: Damage can occur to the Combi and the RV due to an ob-
structed drainage socket! The drainage socket must be unob¬structed and
kept clear of obstructions such as slush, ice, or leaves to ensure that water
can drain properly. No warranty claims for frost dam¬age will be accepted.
Move the lever so that it is in the "drain-
ing" position. Water will drain from the
hot water container via the drainage
socket.
a,b = lever in "valve closed during fur-
nace operation" position
c = lever in "draining" position

Closing the Truma pressure relief/drain valve

Move the lever so that it is in the "closed" position.
Refer to the manufacturer's manual for additional operating and safety information on the
pressure relief/drain valve.

Filling the Water Container

NOTE: Damage to the water container! The water pressure on the
inlet side must be limited to 40.6 psi (2.8 bar); otherwise internal compo-
nents of the appliance will be damaged. On (city) water connections with
a pressure higher than 40.6 psi (2.8 bar) a pressure regula¬tor is strongly
recommended.
1. Close the pressure relief/drain valve, if open
2. Close open bypass lines, if present
3. Turn on the fresh water supply or switch on the water pump
4. Fill the plumbing system:
• Open all water-release points, e.g. cold and hot water faucets, showers, toilets.
• Once water flows, the plumbing system is ventilated and filled. Close all water-
release.

Switching On the Furnace

For the furnace to work properly, there must be enough LP gas (propane >11 in. wc) and 12
VDC power.
Switch on the furnace's 12 VDC power supply.
1. If necessary, fill the water container with water (refer to "Filling the water container").
If no hot water is needed, the Combi furnace can be operated without being filled.
2. Make sure the supply of LP gas is turned on at the tank.
3. Make sure the gas shut-off valve is switched on.
4. Use the CP plus control panel to switch on the Combi.
