Installation Code and Annual Inspections:

All installation and service of ROBERTS GORDON® equipment must be performed by a contractor qualified in the installation and service of equipment sold and supplied by Roberts-Gordon and conform to all requirements set forth in the ROBERTS GORDON® manuals and all applicable governmental authorities pertaining to the installation, service and operation of the equipment. To help facilitate optimum performance and safety, Roberts-Gordon recommends that a qualified contractor conduct, at a minimum, annual inspections of your ROBERTS GORDON® equipment and perform service where necessary, using only replacement parts sold and supplied by Roberts-Gordon.

Installation, service, commissioning and annual inspection of the heater must be done by a contractor qualified in the installation and service of gas-fired heating equipment. Read this manual carefully before installation, commissioning, operation, or service of this equipment. All components are accessed via the hinged door. Opening the door exposes live electrical connections and hot components.

11.1 Pre-Commission Checks

All pre-commission checks must be carried out before lighting the heater.

Ensure that the heater and all controls are suitable for the gas, pressure and electrical supply to which they are to be connected.

11.1.1 Louvres

Where fitted, the air delivery louvres need to be set during commissioning to give the required air distribution.

11.1.2 Electrical Checks

All pre-commission checks must be carried out before commissioning the heater.

1.Check that all site wiring is connected in accordance with the appropriate wiring dia- grams on Page 20, Section 10.3.

2.Check the correct fuse size is fitted; See Page 19, Section 10.1.

11.2 Gas Supply

All aspects of the gas installation including the gas meter must be inspected, tested for soundness and purged in accordance with local and national codes. Ensure that the air is fully purged from the heater inlet pipe up to the main gas valve inlet test nipple.

11.3 Mechanical Checks

1.Check that the fan(s) are free to run and

delivery louvres are turned to give required air deflection.

2.Check that the flue (and air intake for room sealed) is installed in accordance with these instructions and local regulations.

3.The thermostat limit thermodisc is preset and sealed at the factory and is not adjustable.
