Find the propane conversion parts in the plastic bag with this installation
manual. Verify the components with the list below and follow the instruc-
tions to install. .
Conversion Instructions Install the propane spring regulator kit in the gas valve. Follow the
valve manufacturer’s instructions that are included with the spring con-
version kit.
Attach the propane disk near the gas valve.
Install the propane orifice. Refer to FIGURE 28 , page 43, and locate
the gas orifice. Carefully remove the natural gas orifice supplied on the
heater. Install the propane orifice.
Fill in the information required on the gas conversion tape. Select a
location near the rating plate. Be sure the surface is clean and dry and
affix the conversion tape and propane label to the heater.
During heater startup, follow the instructions in Paragraph 7.1.3 to
check the valve outlet pressure.

7.2 Venting and
Combustion Air
All separated combustion units MUST BE equipped with both combustion
air and exhaust piping to the outdoors. The unique concentric adapter box
required with this heater allows for both combustion air and exhaust piping
with only one horizontal or vertical penetration hole in the building.
Concentric horizontal and vertical vent/combustion air systems (Option
CC6 or Option CC2) are the only venting/combustion air systems approved
for high efficiency Model UEAS separated-combustion unit heaters.
Model UEAS units are certified as Category IV heaters. These heaters are
very thermal efficient and will produce condensate during operation. The
heater and its venting system must be connected to a drain. See Para-
graph 7.3, page 28, for instructions on installing the condensate drain.
7.2.1.1 Types of Pipe
Provide field-supplied pipe in the types listed.
Vent Pipe - Schedule 40 PVC or CPVC pipe. In Canada, all PVC vent pipe
must be approved to ULC 636.
Combustion Air Inlet Pipe - Sealed, single-wall galvanized pipe is recom-
mended for the combustion air pipe.
