Design Considerations
When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits, formaldehydes, etc.)
can evaporate. This may result in odors or fumes being emitted into the environment. To correct this
problem, clean the area and/or introduce additional ventilation. The heaters themselves, when installed
and serviced in accordance with the installation manual, do not emit foul odors into the environment.
Design Scenario:
A tube heater system is being installed in a 90' (L) x 50' (W) x 14' (H) space. Two overhead doors are located
at one end and an equipment storage area on one side. The calculated heat load is 400,000 BTU/h.

• Two burners (200,000 BTU each) are placed at one end, opposite the area of highest demand
(e.g., overhead doors).
• Recommended mounting heights are not observed (see Chart 3.1).
• Produces an uneven heat distribution.

highest heat demand.
• Recommended mounting heights have been observed.
• Distributes heat more evenly.
