Commissioning, Louvres, Mechanical Checks

SECTION 10: COMMISSIONING

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 door secured by 4 sheet metal screws. Opening the door exposes live electrical connections and hot components.

WARNING

Electrical Shock Hazard

Use extreme caution while commissioning.

Failure to follow these instructions can result in death or electrical shock.

10.1 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.

10.1.1 Louvres

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

WARNING

1.Check that all site wiring is connected in accordance with the appropriate wiring diagram on Page 14, Section 9.3.

2.Check the correct fuse size is fitted; See Page 13, Section 9.1.

10.1.3 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.

10.1.4 Mechanical Checks

1.Check that the fan is 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.

NOTE: The limit thermostat is sealed at the factory and is not adjustable.

10.2 Begin Commissioning

10.2.1 Before Operating the Heater

To ensure that all the controls are in safe working order, operate the heater for the first time with the isolating gas valve turned off.

1.Turn off the isolating gas valve.

2.Using the installed external control, turn on the

burner. The automatic sequence will now begin as described on Page 16, Figure 9.

There will be no ignition of the burner and lockout will occur, which proves the controls are operating correctly.

Cut Hazard

Turn off gas and electrical supply before maintenance.

Fan can start automatically at any time.

Failure to follow these instructions can result in severe injury or product damage.

10.1.2 Electrical Checks

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