SECTION 10: OPERATION AND MAINTENANCE

Installation, service, 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, 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 during start-up.

Controls compartment contains live electrical connections.

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

10.1 Pre-Start-Up Checks

All pre-start-up 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 Louvers

Where fitted, the air delivery louvers need to be set during start-up to give the required air distribution (optional vertical louvers).

WARNING

10.1.2 Electrical Checks

All pre-start-up checks must be carried out before start-up the heater.

1.Check that all site wiring is connected in accordance with the appropriate wiring diagram on Page 16, Section 9.3.

10.1.3 Gas Supply

All aspects of the gas installation including the gas meter must be inspected, tested for gas tightness 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 louvers are turned to give required air deflection.

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

10.2 Begin Start-Up

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 and power supply turned on.

1.Turn off the isolating gas valve.

2.Turn up the thermostat above room temperature. The automatic ignition sequence will now begin as described

on Page 20, Figure 10.

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.
