WARNING
Due to the confined spaces within marine vehicles, an increased risk of carbon monoxide poisoning causing death or
serious injury to personnel is possible. Therefore, installations in marine vessels are to be performed by Webasto
authorized marine equipment specialists only. It is the marine dealer’s responsibility that the installation complies with all
applicable Coast Guard regulations. Contact Webasto Product North America, Inc. at 1-800-555-4518 for a listing of
authorized marine dealers.
CAUTION
The different vehicle-specific installation conditions should be taken into account. The installation instructions within this
manual are intended for basic installations in common over-the-road vehicles. The installation instructions within this
manual are intended to be used as general installation guidelines only. For information concerning special applications
or applications you are not sure of, contact an authorized Webasto dealer/distributor or Webasto Product North
America, Inc. directly at 1-800-555-4518 (USA) or 1-800-667-8900 (Canada).

Installation Location
The heater should be installed in the vehicle’s interior (with the exception of buses, see section 1 Introduction). If the
heater is installed in an installation housing, such housing must be of a Webasto-approved design.
When installed in the vehicle’s interior, the lead-through openings for combustion air inlet, exhaust gas outlet and fuel
line must be splash-water protected. For this purpose, the special gasket supplied with the heater must be used. The
gasket must be renewed prior to each re-installation.
The heater should be located in or as close as possible to the area being heated. This is acceptable provided the following
criteria is observed and adhered to:
1. Exhaust, combustion air intake and fuel connections must be located outside of the vehicle’s interior.
2. The heater must be mounted on a flat surface to provide an air-tight seal between the heater, gasket and vehicle or
cargo / containment area.
3. Where the heater must be mounted outside of the vehicle’s interior, a splash proof housing must be provided.
When selecting a location for the heater, consider the following:
1. Sufficient space for heating air inlet and outlet ducting. Preferably, where it cannot be damaged during normal use.
2. Combustion air and exhaust location, specifically, clearance around subfloor cross-members and structures, heat
sensitive components and impediments to proper routing of tubes.
3. Fuel line connections and routing.
4. Control / power harness routing.
5. Access to the heater for seasonal maintenance and servicing (see figure 4-1).
