Initial Installation Considerations and Pre-Checks
Placement of the heater is influenced by many factors. Aside from safety factors, considerations for
the general space and heating requirements, availability of gas and electrical supply, and proximity of
possible vent locations are a few examples of factors that should all be considered.
Inspect and evaluate the location of the heater to ensure that the structural support is adequate to
support the unit’s weight. The unit must be installed in a horizontally level position to ensure proper
operation. To reduce noise attenuation along the structure caused by vibration of the unit, the heater
should be installed within 15 feet of a primary building support. In the cases where this installation is
not practical or feasible, the use of spring vibration isolators may be used, so long as they are rated for
use of the unit’s weight (see Chart 1.1).
Adequate space around the heater must also be considered in order to maintain the published
minimum clearance to combustibles and recommended service clearances.
When designing a unit heater system, consider the following:
• Has the building’s heat loss been evaluated?
• Does the design meet the needs of the space?
• Have the recommended mounting heights been observed?
WARNING
!
Improper installation, adjustment, alteration, service or maintenance can cause
property damage, serious injury or death. Read and understand the installation,
operating, and maintenance instructions thoroughly before installing or servicing this
equipment. Only a trained, qualified installation or service personnel may install or
service this equipment.
WARNING
!
Do not locate any gas-fired units in area where chlorinated, halogenated, or acid vapors are
present in the atmosphere. These substances can cause premature heat exchanger failure due
to corrosion, which can cause property damage, serious injury or death.
