Switch For Gas Shut-Off Valve
This switch shuts off the power to the safety gas shut-off
valve and with this the gas supply to the Combi furnace.
To make sure that the gas supply to the furnace is off,
turn the switch to the OFF position.
Switch positions of the switch for gas shut-off valve:
Off = gas shut-off valve is closed
On = gas shut-off valve is open
Your recreation vehicle has an exterior gas shut off valve. In the event you smell gas, all
people and pets should exit the vehicle immediately. Turn off the exterior gas valve until the
source of the smell has been determined, and any problems have been resolved.
Pressure Relief/Drain Valve
™ NOTE: The pressure relief/drain valve pro¬vides both the pressure relief
function and a drain function.
The pressure relief/drain valve is a safety component and must not be removed for
any reason other than replacement.
The pressure relief/drain valve is not serviceable; if defective, it must be replaced.
It must be replaced by a certified service technician.
It must only be replaced by the Truma pressure relief/drain valve rated for 65.25
psi (4.5 bar) which is CSA certified and registered. Tampering with the pressure
relief/drain valve will void the warranty.
Opening the Truma pressure relief/drain valve
™ NOTE: Damage can occur to the Combi and the RV due to an obstructed
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
furnace 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 components of the ap-
pliance 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
