SECTION 4: CRITCAL CONSIDERATIONS

SECTION 4: CRITCAL CONSIDERATIONS 4.1 Ventilation

WARNING

Carbon Monoxide Hazard

Heaters may be installed vented or unvented.

Vented heaters must be vented outdoors.

Unvented heaters must be installed in buildings with ventilation rates as per section 7.

Failure to follow these instructions can result in death or injury.

It is important to ensure that there is adequate air circulation around the heater to supply air for combustion, ventilation and distribution in accordance with local and national codes.

4.2 Gas Supply

It is important that the gas supply pipe is sized correctly to provide the inlet pressure as stated on the heater data plate. The gas supply pipe and electrical connections must not support any of the heater's weight.

4.3 Electrical Supply

DANGER

Electrical Shock Hazard

Disconnect electric before service.

Heater must be properly grounded.

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

A permanent 230 V 50 Hz 1Ø electrical supply is required at the main electrical terminals. The heater also requires suitable energy controls in accordance with Section 10.

4.4 Flue

Choose heater siting to allow for the proper location of the flue. Each heater must be fitted with an individual and correctly sized sealed flue system (See Page 13, Section 7).

No other appliance may be connected to the flue. For room sealed installation, the air intake must be the same size sealed system and the flue/air intake must terminate at an approved concentric wall or roof terminal.
