SECTION 3: CRITICAL CONSIDERATIONS
SECTION 3: CRITICAL CONSIDERATIONS 3.1 Basic Information
CTU heaters have automatic ignition burners for ON/OFF operation only.
3.2Location and Suspension All models:
• Must be installed indoors.
• Must be installed in a level position.
•May be mounted on a shelf of
•May be suspended from above (See Page 9, Figure 2) or from wall brackets of sufficient strength to support the heater as listed in the Dimension Data Table on Page 5, Section 4.1. Drop rods must be a minimum of 10 mm diame- ter mild steel. Four suspension points (M10 nuts) are located on top of the heater.
•Must be installed in a manner which allows the hinged door to be fully opened to provide access to all serviceable components.
3.3 Minimum Required Installation Clearances
Clearances around the heater and flue must be as indicated on Page 4, Figure 1, Page 10, Figure 3 through Page 11, Figure 6 to ensure access for servicing, and correct operation.
3.4 Clearances to Combustibles
Clearances must be as indicated on Page 4, Figure 1. If clearances to combustibles are not indicated, then installation clearances apply.
3.5 Ventilation
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.
3.6 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.
3.7 Electrical Supply
A permanent 230 V 50 Hz electrical supply is required at the main electrical terminals. The heater also requires suitable energy controls in accordance with Section 10.
3.8 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 10, Section 6).
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.
