Some Safety Insights Regarding Our Exhaust Systems For FJH Air Heaters
For each FJH Air Parking heater or mainly 2 Kw Air heater or 5 Kw water heater, universal installation kit includes a flexible exhaust pipe. The inner diameter is Ø 24 mm, while it is 1000 mm long. It also contains an exhaust silencer. The flexible exhaust pipe can be shortened to 20 cm or lengthened to max. 2 m, depending on the installation conditions.
Fasten the exhaust silencer to a suitable position in the vehicle. Route the flexible exhaust pipe from the heater to the exhaust silencer and fasten with pipe clips. Use a pipe clip to fix a short exhaust pipe end (with end sleeve) to the exhaust silencer.
2. Safety Regulations!
The whole exhaust system gets very hot during and immediately after the heater has been working. This is the reason why the exhaust system must be installed according to these instructions.
The exhaust outlet must end in the open air.
The exhaust pipe must not protrude beyond the lateral limits of the vehicle.
Install the exhaust pipe sloping slightly downwards.
If necessary, make a drain hole approx. Ø 5 mm at the lowest point to drain off condensation.
Important functional parts of the vehicle must not be impaired (keep sufficient clearance).
Mount the exhaust pipe with sufficient clearance to heat-sensitive parts.
Pay particular attention to fuel pipes (plastic or metal), electrical cables and brake hoses etc.!
Exhaust pipes must be fastened safely (rec clearance of 50 cm) to avoid damage from vibrations.
Route the exhaust system so that the emitted fumes are not sucked in with the combustion air.
The mouth of the exhaust pipe must not get clogged by dirt and snow.
The mouth of the exhaust pipe must not point in the direction of travel.
Always fasten the exhaust silencer to the vehicle.
3. Risk of Injuries and Burn
Every type of combustion produces high temperatures and toxic exhaust fumes. This is the reason why the exhaust system must be installed according to these instructions.
Do not perform any work on the exhaust system while the heater is working.
Before working on the exhaust system, first switch the heater off and wait until all parts have cooled down completely, wear safety gloves if necessary.
Do not inhale exhaust fumes.
If a silencer is fitted, the exhaust end pipe must be much shorter than the flexible exhaust pipe between the heater and the exhaust silencer.
Small arrows indicating the direction of flow have been cast into the fittings to differentiate between the combustion air and the exhaust fittings at the heater
