SECTION 3: CRITICAL CONSIDERATIONS

SECTION 3: CRITICAL CONSIDERATIONS 3.1 Basic Information

UHA[S] 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 with horizontal discharge.

•May be mounted on a shelf of non-combustible material.

•May be suspended from above (See Page 6, Figure 2) or from wall brackets of sufficient strength to support the heater as listed in the Dimension Data Table on Page 38, Section 15.1. Drop rods must be a minimum of 3/8" diameter mild steel. Four suspension points (3/8" nuts) are located on top of the heater.

•Must be installed in a manner which allows access to all serviceable components. See Page 4, Figure 1 for details.

3.3 Minimum Required Installation Clearances

Clearances around the heater and vent must be as indicated on Page 4, Figure 1; Page 9, Figure 3 through Page 12, Figure 8 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 space around the heater to supply air for combustion, ventilation and distribution in accordance with local and national codes on Page 7, Section 6.

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 on Page 14, Section 8.

3.7 Electrical Supply

A permanent 120 V 60 Hz 1 Ø electrical supply is required for the main electrical power. The heater also requires suitable controls in accordance with See Page 15, Section 9.

3.8 Vent

Choose heater orientation to allow for the proper location of the vent. Each heater must be fitted with a correctly sized sealed vent system.

If vented horizontally, no other appliance may be connected to the vent. See Page 7, Section 6.

3.9 Separated Combustion Installation

For separated combustion installation, the vent and air intake must be fitted with an individual and correctly sized sealed system and the vent and air intake must terminate at approved wall and roof terminals.

Separated combustion units may not be common vented. See Page 7, Section 6.
