10.Unit Heater Location

Use the sound data in Paragraph 6, clearances in Paragraph 8; the combustion air requirements in Paragraph 9; the throw tables, mounting height requirements, and location recommendations below; the weights in Paragraph 11; and the venting requirements in the Venting Manual to determine where to suspend the heater.

Heater Throw

FIGURE 6 - Throw for Fan Models UDAP and UDAS

NOTE: Throws listed are with standard adjustable horizontal louvers at the angles listed (angle is relative to the top of the heater). Throw pattern changes with the addition of optional vertical louvers and/or downturn nozzles.

Location Recommendations

Locate the heater so that it is a minimum of five feet (1.5M) above the floor and in compliance with the clearances in Paragraph 8.

WARNING: If touched, the vent pipe and internal heater surfaces that are accessible from outside the heater will cause burns. Suspend the heater a minimum of 5 feet (1.5M) above the floor.
