Troubleshooting guide

In locations used for the storage of combustible materials,
signs must be posted to specify the maximum permissible
stacking height to maintain the required clearances from the
heater to the combustibles. Signs must either be posted
adjacent to the heater thermostats or in the absence of such thermostats, in a
conspicuous location.
Keep these instructions for future reference.
Please read and save these instructions. This heater must be installed and serviced by trained gas installation and service
personnel only! Read carefully before attempting to assemble, install, operate or maintain the product described. Protect
yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury
and/or property damage! Retain these instructions for future reference.

Dayton Tube Heaters
®
Description
Dayton tube heaters are gas-fired infrared heaters designed to provide comfort heat.
They consist of three (3) main components: a burner control box, radiant tube, and
reflector assembly. The heaters are typically suspended from the ceiling by chains
and controlled by a thermostat. They can be installed either vented or unvented,
and may use outside air for combustion if necessary. The radiant tube may be
installed in different configurations depending on the heating requirements.
These heaters use infrared energy to heat spaces. When heat is required, the
burner control box ignites a gas/air mixture and pushes the hot gases into the
radiant tube. As the gases pass through the assembly, the tubing is heated
and emits infrared, which is then directed toward the floor by reflectors. This is
known as primary infrared and is absorbed by the floor, objects and people in
the space, raising their temperatures. They in turn re-radiate this heat, known
as secondary infrared, to create a comfort zone at the floor level. This is how
Dayton tube heaters can heat large spaces without having to provide primary
infrared for every square foot of area. However, if the goal is to spot heat a
small area within a large space, only the primary infrared makes this possible.
Dayton tube heaters are design certified for use in industrial and commercial
buildings, such as warehouses, manufacturing plants, aircraft hangars and
vehicle maintenance shops. They are not certified for residential use or where
flammable gases or vapors are generally present, such as spray booths.
