The propane kits appearing in this bulletin are for use with units
which are going to be installed between 0 and 2000 ft. elevation.
If a unit is to be installed at higher elevations, a special “high
altitude” propane orifice kit must be ordered in addition to the
propane conversion kits shown here. See Bulletin 75-535 for
selection of “high altitude” orifice kits.
When converting units to propane at elevations over 2000 ft.,
the main burner orifices in the propane conversion kit must
be replaced with the orifices from the “high altitude” orifice kit.
The remaining components of the propane kit, those other
than the main burner orifices, are still required to complete the
conversion to propane gas, regardless of the elevation at which
the unit is installed.
Identifying the Model, Control Code and
Date of Manufacture
Figure 2.1, shown on the next page, is an example of a typical
serial plate. Markings pertinent to verifying correct application
of the conversion kit are identified and explained in detail.
All
prerequisites must be satisfied before the unit is deemed
convertible.
1. The first two or three characters in the model number box
are letters. These letters identify the style of the heater. If
any of the following model prefixes appear in this box, the
unit is potentially convertible: PD/BD, PDP/BDP, PV/BV,
DJE, IJE, DFG, IFG, NFG, DFP, IFP, DFS, IFS.
2. Next, the number 11, 12, 13, 14, 30, 31, 32, or 33 must be
the control code or digits 11 and 12 of the model number
are N1 or S1. This is item (2) in Figure 2.1. Any other
number code disqualifies the unit for conversion.
3. Item (3) in Figure 2.1 in the serial number box designates
the date the unit was built. In Figure 2.1, the numbers
3601 are shown. This number is interpreted as the thirty
sixth week of 2001. Prior to January 1995, the digits
preceding the year represent month of manufacture. After
January 1995, the (2) digits proceeding the year represent
the week of manufacture. Any serial number dated 4/91 or
after is acceptable for conversion.

SELECTION AND INSTALLATION INSTRUCTIONS
conversion from natural gas to propane gas for
models PD/BD, PDP/BDP, PV/BV, DJE/DHE, IJE/IHE
with control codes 11-14 or 30-33 and built 4/91 or after,
“D” and “I” series duct furnace/make up air units with
digits 11 & 12 = N1 or S1
WARNING
1. All field gas piping must be pressure/leak tested prior to
operation. Never use an open flame. Use a soap solution
or equivalent for testing.
2. Gas supply shall be shut-off and the electrical power
disconnected before proceeding with the conversion.
Failure to do so could result in fire, explosion or electrical
shock.
1. The use of this manual is specifically intended for a
