steam/hot water unit heaters

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 coils are warranted for operation at steam or hot
water pressures up to 150 lbs. per sq. in., 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) requirements
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 9234.5C. *Does not apply to WVC/WPC 952.
CAUTION
Do not remove outlet fan guard from vertical
type unit heaters.
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 WTC 63 has an output of 63,000
Btu/Hr. at 2 lbs. steam and 60°F entering air.
