Recommended Exhaust Outlet Locations
The following is recommended for a van exhaust outlet location:
• Mount the exhaust o utlet outside the van, not inside the
heater compartment. Otherwise, exhaust fumes could
infiltrate the van from The WindowWasher™ by ITR
compartment.
International Thermal Research 3-1
Section 3, Installing the Exhaust System
• In a van, the typical mounting location for the exhaust
outlet is under the floor of the heater compartment, or on
the other side of the van, directly across from the heater
unit. Keep in mind you cannot exceed 12’ of exhaust
piping, including bends.
• Position the outlet of the exhaust pipe so that the exhaust
exits off the side of the van, not towards the front, back,
directly underneath the van, or under an openable
window, vent or sliding door.
Recommendation for Installation
• You may use sweep bends but each 90° bend is equ ivalent
to two feet of exhaust piping. For example, if you use two
90° bends you must deduct two feet per bend from the
maximum allowed 12’ straight exhaust pipe length.
Therefore you will be restricted to 8’ of straight exhaust
piping plus the two bends. Do not exceed these
recommendations.
! DANGER
• The combustion air-intake must use 100% outside air.
• Use an ITR-manufactured muffler or silencer; no other is
acceptable.
• Exhaust outlet is on the top or bottom of The
WindowWasher™ by ITR, towards the back.
The exhaust and outlet are HOT and the surrounding areas
must be thermally shielded and protected from the hot
surfaces and heat buildup by insulation. Nothing can come
into inadvertent contact with any part of the exhaust system
• Exhaust pipe must have a minimum of 3” (7.6 cm)
clearance from all surfaces.
• Ensure that the exhaust cannot be plugged or restricted.
• The exhaust fitting on The WindowWasher™ by ITR is
1.5” O.D. and the exhaust pipe used must have a
minimum of 1.5” I.D throughout its length.
• All exhaust elbows must be of a large radius design
(minimum radius 2.0”).
3-2 The WindowWasher™ by ITR
Section 3, Installing the Exhaust System
• The exhaust must be supported a minimum of e very 3’ of
its installed length.
• The exhaust and The WindowWasher™ by ITR connection
point must use appropriate clamps and sealing compound
to ensure that the connections are tight and leak free. The
WindowWasher™ by ITR exhaust outlet pipe and the
exhaust pipe itself must not be distorted or damaged
during this process.
• With The WindowWasher™ by ITR running, the connection
points and the system must be checked for leaks and any
found must be corrected. Periodically, check the exhaust
fittings, connections, exhaust tube and insulation for leaks
and integrity and correct if required.
• Install an exhaust collar on the exhau st pipe to isolate the
pipe from the van.
What NOT to Do
Don’t mount the exhaust pipe inside the heater compartment.
Don’t use more than 12’ of total exhaust length (including
bends)
Don’t use mufflers with any flow restrictions.
Don’t over tighten exhaust clamps or you may crush The
WindowWasher™ by ITR’s exhaust spout.
3.3 Procedure
Figure 3-1 shows a standard setup for the up exhaust. To install

2 Two male 1/2” NPT PEX tube fittings (not supplied) must be fit
into the supply and return fittings and tightened to a leak free
condition.
3 Connect the domestic water holding tank to the Cold Wate
Inlet. In some installations, a check valve may have to be
obtained and installed on the cold input line to
WindowWasher™ by ITR to prevent warm water from
backfilling to the water storage tank. Check the appropriate
standards and regulations. Ensure there are no kinks or sharp
bends that might restrict the fluid flow. If bends are required
for PEX tubing, fit the tubing into a plastic bend support. Do
not use rubber heater hose for potable water plumbing.
4 Connect the hot water supply line to the Hot Water Outlet.
Ensure there are no kinks or sharp bends that might restrict
the fluid flow. If bends are required for PEX tubing, fit the
