# §3285.904. Utility system connections.

- (a) It is recommended that the manufacturer's installation instructions indicate the following procedures be used prior to making any utility system connection:
  - (1) Where an LAHJ and utility services are available, that the LAHJ and all utility services each be consulted before connecting the manufactured home to any utilities, or
  - (2) Where no LAHJ exists and utility services are available, that the utilities be consulted before connecting the manufactured home to any utility service; or
  - (3) In rural areas where no LAHJ or utility services are available, that a professional be consulted prior to making any system connections.
- (b) **Qualified personnel.** Only qualified personnel familiar with local requirements are permitted to make utility site connections and conduct tests.
- (c) **Drainage system.** The main drain line must be connected to the site's sewer hookup, using an elastomeric coupler or by other methods acceptable to the LAHJ, as shown in Figure A to this section.
- (d) **Fuel supply system.**
  - (1) **Conversion of gas appliances.** A service person acceptable to the LAHJ must convert the appliance from one type of gas to another, following instructions by the manufacturer of each appliance.
  - (2) **Orifices and regulators.** Before making any connections to the site supply, the inlet orifices of all gas-burning appliances must be checked to ensure they are correctly set up for the type of gas to be supplied.
  - (3) **Connection procedures.** Gas-burning appliance vents must be inspected to ensure that they are connected to the appliance and that roof jacks are properly installed and have not come loose during transit.
  - (4) **Gas appliance start-up procedures.** The LAHJ should be consulted concerning the following gas appliance startup procedures:
    - (i) One at a time, opening equipment shutoff valves, lighting pilot lights when provided, and adjusting burners and spark igniters for automatic ignition systems, in accordance with each appliance manufacturer instructions.
    - (ii) **Checking the operation of the furnace and water heater thermostats.**
