INSTALLATION AND SERVICE MANUAL
steam/hot water unit heaters
Inspection On Arrival
1. Inspect unit upon arrival. In case of damage, report it
immediately to transportation company and your local factory
sales representative.
2. Check rating plate on unit to verify that power supply meets
available electric power at point of installation.
3. Inspect unit received for conformance with description of
product ordered (including specifications where applicable).
General Information
Installation and service instructions in this manual are applicable
to the three types of steam/hot water unit heaters which should
be installed in their proper applications for their most effective
function as overhead heating units.
The copper condensers are warranted for operation at steam
or hot water pressures up to 150 lbs. per sq. in. gauge, and
or temperatures up to 375°F, cupronickel tube units are
warranted for operating pressures up to 250 PSI and operating
temperatures up to 400°F. Canadian Standards Association
(CSA) requriements state that explosion-proof units may not
be used with a fluid temperature in excess of 329°F and still
maintain their explosion-proof rating, for national electric code
ignition temperature rating T3B for grain dust.
Motors are designed for continuous duty. They can operate in a
maximum ambient temperature of 104°F (40°C).
The unit heaters are listed by the Canadian Standards
Association as certified and Canadian Registered heat
exchangers CRN OH 9234.5.
Steam horizontal and vertical delivery unit heaters are available
in both standard and low-outlet temperature models. Low outlet
temperature models are recommended primarily for installation
on heating systems with steam pressures of 30 to 150 PSI.
When used at these steam pressures they provide lower outlet
air temperatures for longer heat throw and, because of wider
fin spacing, they are less susceptible to clogging in dusty
atmospheres.
The model number of each unit heater indicates its rated Btu/Hr.
capacity/1000 at 2 lbs. steam pressure and 60°F entering air
temperature. For example an HSB-63 has an output of 63,000
Btu/Hr. at 2 lbs. steam and 60°F entering air.
