Switch For Gas Shut-Off Valve; Room Temperature Sensor; Truma Pressure Relief/Drain Valve - Truma Combi eco Operating Instructions Manual

Switch for gas shut-off valve

The switch (Fig. 4) 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.

Truma pressure relief/drain valve

Risk of scalding injury from hot water
and/or tampering with the pressure relief/
drain valve!
• Never actuate the pressure relief/drain valve
as long as the Combi furnace is still hot.
• Do not place a plug or reducing coupling
on the outlet part of the valve. If you use a
discharge line, allow the valve and the line
to drain completely.
– The Truma 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 ser-
viceable; 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.
The Combi furnace with supplementary indirect
water heating must be installed with the Truma
pressure relief/drain valve (Fig. 5) that complies
with the standard for Relief Valves for Hot Wa-
ter Systems, ANSI Z21.22.
