Recommended Annual Habitation Service Check
INTRODUCTION
There is much confusion over the annual habitation service or check for motorhomes, with widely varying prices and standards of work. However a 'standard checklist' is used by many dealers when carrying out this work, but it seems that many owners are not aware of this, or of what checks should be included. We suggest that owners should ask for the 'SMMT Annual Habitation Service Check' to be carried out. Competent owners may wish to use the published checklist when carrying out their own maintenance.
The following guidelines for the checking and servicing of a motorhome's habitation area are taken from the guidance booklet published by the Motorhome Section of the Society of Motor Manufacturers and Traders (SMMT) and the Motorhome Division of The National Caravan Council (NCC). They are © SMMT & NCC and reproduced here with their kind permission. We would like to thank them for providing this information and also thank The Motorhome Information Service for their assistance.
The checks do not cover any part of the base vehicle, although there may be minor overlapping (such as tyre pressures, cab seats, internal lights, battery and windows) in a van conversion. The base vehicle must be serviced in accordance with the chassis manufacturer's instructions.
Reference should also be made to:
1. Any owner's manual or equivalent supplied with the vehicle by the motorhome manufacturer.
2 Appliance manufacturers' leaflets.
3. Driver s handbook or equivalent supplied by the chassis manufacturer.
A vehicle is accepted for service at the dealer's discretion.
Any defects, repairs, adjustments, cleaning or lubrication required will be noted on the check list.
The customer's approval will be obtained before any work is done.
Not all of the equipment mentioned in this manual is fitted as standard to every motorhome
Any work carried out following the check, and the sufficiency of the work in the check itself, is subject to the contract between the customer and the dealer. The National Caravan Council (NCC) & SMMT and their member companies are not part of this contract, and accept no liability in contract, tort or otherwise, other than death or personal injury due to negligence on their part.

6.10 PORTABLE OR OPEN FLAME HEATING EQUIPMENT
Check for its presence. The customer must be advised against its use.
SECTION 7
ELEVATING ROOFS
7.1 LIFTING MECHANISM

SECTION 8
GAS SYSTEMS
8.1 CYLINDERS AND REGULATORS
Establish that the cylinders and regulators are compatible. Butane (blue) cylinders should have a regulator stamped with the pressure 11" WG (28 m bar) and propane (red) cylinders should be stamped 14" WG (37 m bar). Check that the regulator is controlling the gas to the correct pressure for the type of cylinder fitted.
Check cylinder compartment vents and gas drop hole in the floor are free from obstruction.
Check seals on internal doors.
8.2 HOSE AND PIPING
Check any flexible hose is of an approved type. Check its condition and for any evidence of cracking.
Check piping for condition, damage and correct support.
Carry out an overall leak test.
8.3 APPLIANCES
In general, the checking of gas appliances can be divided into the following:
1. Cleaning 4. Flues
2. Operation of controls 5. Flame failure device
3. Correct flame structure 6. Security
8.3.1 CLEANING
Where appropriate, remove cover(s) to gain access to heat exchanger.
Clean away any fluff or foreign matter. Reassemble and test.
Clean flame viewing window.
8.3.2 CONTROLS
Check that all knobs etc. work smoothly and are secure on their spindles.
If gas taps require greasing to ease stiffness, use only approved LPG grease.
Check that appliances can be brought into service using the normal controls.
8.3.3 CORRECT FLAME STRUCTURE
Check that all pilot flames burn quietly and clearly.
Refrigerator: With the refrigerator gas control turned to maximum, the colour of the flame should be predominantly blue.
Instantaneous Water Heating: The main burner flame should be of even height and blue in colour. A flame burning yellow will allow sooting to occur.
Ovens: The oven flame should burn quietly and be of even height, mainly blue/green in colour. If the gas is propane, the flame will normally develop yellow tips as the burner heats up. If the gas is butane, a small amount of yellow tipping will be seen immediately after lighting, increasing as the burner heats up.
Grill Burners: It is normal for the flames on this type of burner to develop yellow tips as it heats up, particularly on butane.
General: A flame lifting away from the burners is an indication of too high a pressure, although it may happen with grill burners whilst the frets are heating up.
A yellow flame will cause sooting and is an indication of too low a pressure.
Providing the regulator and piping have been checked and found satisfactory the above faults should not appear.
8.3.4 FLUES
Flues should be examined for security of fixing and for correct attachment to appliances and flue terminals. They should be free from damage and corrosion.
Check for leakage of flue gases into the vehicle.
8.3.5 FLAME FAILURE DEVICE (FFD)
Where fitted, the FFD should be checked to ensure satisfactory operation. After the appliance has been successfully checked, allow time for the thermocouple to cool.
Attempt to relight the appliance by turning it on without pushing in the gas control knob. (Do not override the FFD). If appliance does not light, FFD is satisfactory.
8.3.6 SECURITY
Check appliance is securely fixed to the vehicle/furniture and will be free from rattles. Where applicable, check that water pipes are satisfactorily attached with no sign of leakage
8.3.7 PROTECTION OF ADJACENT SURFACES
Check that surfaces adjacent to open flame cooking appliances have adequate protection.
8.3.8 INSPECTIONS
It is recommended that inspections are carried out by a qualified fitter
trained to, for example, CORGI (Confederation of Registered Gas Installers) or Calor standards.
SECTION 9
WATER SYSTEM
Before operating the water system, a visual check of the following items may show up an obvious leak source.
9.1 FRESH WATER TANK CONTAINER
Check condition, fill tank and check for leaks.
Check the external filter and filter pipe to tank.
Check for satisfactory venting.
Check condition and presence of filter cap.
9.2 WASTE WATER TANK
Check drain tap is clear and working.
Check condition and presence of drain hose. (The water tank will be drained, flushed, cleaned and charged with a measure of toilet fluid/disinfectant at the prior request of the customer.
9.3 FILTER PUMP
When applicable, remove filter and replace.
Check the in-line pump for security and condition. Remove the
submersible pump from tank, check condition.
Check pump inlet and outlet are clear and not obstructed.
Check delivery hose and electric cable are secure and satisfactory
Operate pump. Check all piping for leaks.

Check all connections and joints are sound and satisfactory
10.1.3 FUSES/FUSE HOLDERS
Ensure that fuses and fuse holders used to protect the habitation electrics are satisfactory and that fuse ratings are compatible with the circuit appliances being protected.
10.1.4 APPLIANCES
Inspect all appliances for damage, signs of overheating and secure fixing
Function test all appliances.
