Flue Assembly Installation
1. Locate the collapsed flue assembly in the
compartment above the gas heat controls by removing
the panel screws. The assembly is secured by screws
up through the roof of the gas controls compartment
roof.
2. Separate the pieces of the collapsed assembly.
3. Then assemble the stack as shown in Figure48.
4. Insert the tube on the flue assembly into the hole located
 in the vertical support for the heat section.
5. Butt both tube sections together and...

General Coil Piping and Connection
Recommendations
Proper installation, piping, and trapping is necessary to
ensure satisfactory coil operation and to prevent
operational damage:
 Support all piping independently of the coils.
 Provide swing joints or flexible fittings on all
connections
 that are adjacent to heating coils to
absorb thermal expansion and contraction strains.
 Install factory supplied control valves (valves ship separately).
Note: The
 contractor is responsible...

 After completing the piping connections, seal around
pipe from inner panel to outer panel.
Hot Water Heat Units
Hot water heating coils are factory installed inside the
heater section of the unit. Once the unit is set into place,
the hot water piping and the factory provided three way
modulating valve must be installed. The valve can be
installed inside the heat section or near the unit. If the
valve is installed in a remote location, use field supplied
wiring to extend the...

7. Install a “Gate” type valve in the supply branch line as
close as possible to the steam main and upstream of
any other device.
8. Install a “Gate” type valve in the return branch line as close
 as possible to the condensate return main and
downstream of any other device.
9. Install a strainer as close as possible to the inlet of the control
 valve and steam trap(s).
10. Steam trap selection should be based on the maximum
 possible condensate flow and the
recommended load...

Disconnect Switch w/External Handle
Units come equipped with a factory mounted disconnect
switch with an externally mounted handle.This allows the
operator to disconnect power from the unit without having
to open the control panel door. The handle locations and
its three positions are shown below;
“ON” - Indicates that the disconnect switch is closed,allowing the main power supply to be applied at the
unit.
“OFF” - Indicates that the disconnect switch is open, interrupting the...

Main Unit Power Wiring
Figure 56, p. 80lists the field connection wire ranges for
both the main power terminal block and the optional main
power disconnect switch. The electrical tables beginning
with Table 22, p. 81 list the component electrical data.The
electrical service must be protected from over current and
short circuit conditions in accordance with NEC
requirements. Protection devices must be sized according
to the electrical data on the nameplate. Refer to the “Power...

Note:Non-fused disconnect switch size is
calculated by selecting the size
greater than or equal to 1.15 X (sum of
unit loads). See unit literature for unit
load values. (See following page for
circuit breaker sizing)
