Clearance from exhaust components – what is recommended?

Short answer: Clearance requirements depend on exhaust surface temperature, airflow, duty cycle, vibration, and whether the exhaust is insulated. If clearance is limited, use a combined approach: reduce heat at the source and then protect the hose/wiring.

Practical guidance:

• More clearance is always safer: it reduces both radiant heating and accidental contact under vibration.
• If clearance is limited: insulate the exhaust/hot source using exhaust insulation solutions to reduce surface temperature and radiant emission.
• Protect nearby lines: use fire sleeve or an appropriate thermal sleeve on hoses/wiring.
• Treat “almost touching” as contact heat: vibration can turn near-contact into contact; add abrasion control at brackets/clamps using tapes and barriers.

Fast confirmation: send a routing photo with a reference scale (ruler or known hose size), plus measured max exhaust surface temperature if available. We will recommend a safer configuration.
