Maintenance
Routine Maintenance
All tap aerators and showerheads should be cleaned regularly.
It is recommended that the IWH-1.5 be inspected by a qualified service technician at least
once a year. Particular attention should be paid to the following:
1.
Be sure that the air inlet openings and flue area (screen) are clear of any debris or
obstructions, (leaves, bug nests, spider webs, etc.)
2.
Check that heater mounting is still secure to the RV and that there are no areas for
potential water leaks.
3.
Open the cover of the heater and inspect for debris or obstructions under the burner,
around the blower motor or in flue hood.
4.
Visually inspect wiring. Be sure there is no chafing of the insulation. Be sure that the
direct spark ignition, the ground and the flame detection cable is secured to the
electrodes at the left side of the burner.
5.
Inspect the interior surface of the housing for any cracks or corroded areas that could
allow penetration of gases into or out of the interior of the vehicle. Check especially
around the Hot Water, Cold Water, Gas and electrical connections.
6.
Check for soot around the flue. Soot is a sign of incomplete combustion and a
qualified service technician should be notified to correct the problem.
7.
Check the pressure relief valve if it's tight under normal conditions. Test also the
operation of the drain valve for proper function.
Note: never open the drain valve during the operation of the water heater.
8.
Turn on the power to the water heater and open a hot water tap to inspect the flame
of the burner. The flame should be of the normal bluish appearance that indicates
proper combustion. You can observe the flame through a line of small holes at the
front side of the burner.
9.
Depending on the environmental conditions, the exhaust pipe might get a matt
surface out of aluminum oxide. This is normal and a kind of protection surface.
Winterising and draining water
It is not recommended that you operate water system at below zero temperatures. Any
freezing of the water heater or other plumbing components can cause severe damage that is
not covered by warranty.
NOTE: Under no circumstances, however, should you travel under freezing conditions
without first draining water from the unit. To drain the system:
1.
Turn off water pump and the power and gas to the heater. Open the drain valve by
turning the handle to a 90° position from the normal position.
2.
Open drain valve that was installed at hot water outlet fitting of heater.
3.
Open at least one hot and cold water tap in the coach. This should drain the system.
Before storing the system for the winter, the plumbing system must be winterized. This can
be done by either of the following methods:
All water should be drained from the system. To do this, open one tap at a time, using
compressed air (less than 2 bar) to purge the system of all water.
Recommendations of your RV manufacturer should be followed. Since the IWH-1.5 has
no storage tank, there is no need for a water heater bypass kit. It holds less than 0.3L
of water. The water system can be filled with RV, non-toxic anti-freeze, which doesn't affect
copper and brass. When you see the anti-freeze coming from the hot water tap, the heater is
protected.
