Upgrade Your RV with the WOLF 6000AW Air and Water Heater

If you’re looking for a high-efficiency air heating and hot water solution for your RV or motorhome, the WOLF 6000AW Combi Heater is one of the most powerful and compact systems available. Whether you’ve chosen the diesel or propane version, proper installation is critical for long-term performance, safety, and reliability. This step-by-step guide walks you through the process based on manufacturer recommendations.

Pre-Installation Checklist

Before starting, make sure you have:

  • Correct model based on voltage and fuel type (12VDC, 120VAC; Diesel or Propane)
  • All components from the heater kit
  • Adequate  installation space in your RV or compartment
  • Basic  tools: drill, screwdrivers, clamps, zip ties, etc.

Important: Always read the full user manual and follow safety precautions. Installations performed by GC-authorized professionals or GC Approved self-installs are backed by a 2-year limited warranty.

1. Heater Placement

  • Install in a dedicated compartment with an air intake opening of at least 25 in²
  • Minimum space: 22”W x 20”D x 14”H
  • Avoid using the compartment for storage and ensure easy access for maintenance

2. Combustion Air & Exhaust Routing

  • Route exhaust and intake ducts through the RV side wall
  • Total duct length: 60–100 cm (2–3 ft)
  • Exhaust line should sit lower than the heater’s exhaust outlet to prevent condensation
  • Secure ducting with included clamps and straps

3. Combustion Air Line Installation

  • Drill an 83 mm (3¼”) hole for the air flue fitting
  • Align properly using markings like “Top”
  • Ensure tight, vibration-free connections with supplied clamps and hardware

4. Warm Air Ducting Setup

  • Four 60 mm warm air outlets available
  • Direct heat away from the heater compartment to avoid air recirculation
  • Seal unused lower ports; use 90° elbows for sharp duct turn
  • Avoid short runs (<20”) to maintain airflow

5. Fuel Line Installation (Diesel Models)

  • Can connect to vehicle’s tank or 10L auxiliary tank (if included)
  • Do not tap into pressurized vehicle fuel lines
  • Maximum lengths:
    - Tank to pump: 2 m (6 ft)
    - Pump to heater: 6 m (18 ft)
  • Mount fuel pump at a slight angle—not horizontally—for optimal operation

6. Water System Connection

  • Water tank capacity: 10L, with built-in pressure control
  • Max water pump pressure: 2.8 bar
  • Use anti-freeze valve for winterization
  • Install pressure relief valve with drain line to prevent pressure buildup

7. Room Temperature Sensor Installation

  • Mount away from heat sources, windows, and direct sunlight
  • Ideal location: interior wall, 4–5 ft off the floor
  • Drill 10 mm (3/8”) hole for sensor installation

8. LCD Controller Installation

  • Position controller where cable easily reaches the heater
  • Cutout size: 3 9/16”H x 2 15/16”W
  • Mount flush and secure with included bracket and screws

9. Electrical Connections

  • Connect all DC wiring inside a sealed heater compartment
  • Bundle wires neatly and leave slack for serviceability
  • Avoid strain on wires; use proper wire gauge to minimize voltage drop
  • Reinstall the cover after wiring

Pro Tip: Poor power connections are a leading cause of heater faults.

⚠️ Fault Code Awareness

Your WOLF 6000AW has a smart controller with fault codes for troubleshooting:

  • Code 31: Combustion failure
  • Code 43: Water overheating
  • Code 61: Fuel pump issue

Refer to your manual for the full fault code chart and solutions.
