Environment, Ventilation and
Combustion Air Requirements
Ventilation must be suffi cient to maintain a building
temperature of 120°F (49°C) or less. Consistent proper
ventilation of the equipment room is essential for good
combustion.
NOTE:  When calculating ventilation requirements, heat
losses from the Fulton equipment (and other equipment)
should be considered.
Adhere to the following to meet ventilation and combustion
air requirements:
1. Install two fresh air openings, one at a low level, 24” (610
mm) from the fl oor, and one at a higher level on the
equipment room wall. This will provide a fl ow of air to
exhaust the hot air from the equipment room.
2. Ensure the burner has an adequate supply of air. Based
on NBIC recommendations, unobstructed air openings
must be sized on the basis of 0.5 square inch of free
area per 1,000 BTU/hr input maximum fuel input of
the combined burners in the equipment room or as
specifi ed by applicable codes.

Notes
1. Thermal fl uid heater is of four-pass combustion
design.
2. First pass (radiant): combustion air enters burner fan
and travels upward between inner and outer jacket
before it enters top-mounted burner.
3. Second pass (convection): Gases travel back across
the inner row of coils.
4. Third pass (convection): Gases continue back down
between inner and outer coil.
5. Fourth pass: Upward between the outer coil and
inner jacket to the fl ue outlet.
