Exhaust Muffler

Webasto recommends installing an exhaust silencer to reduce noise. The installation must satisfy the following
requirements:
- The installation location is as close as possible to the heater.
Installing exhaust muffler:
- Ensure the correct installation position.
- Do not secure the exhaust muffler to heat-sensitive parts (e.g. brake lines, electrical cables).
- Maintain adequate distance from heat-sensitive parts. A heat shield can be fitted.
- Install exhaust muffler such that condensation can drain off through the condensation drain hole in the exhaust
muffler.
