The propane gas 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 Modine
Bulletin 75-537 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 gas 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 on the next page explains Modine HD/HDS unit heater
model number designations and serial number designations.
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 characters in the model number are letters.
These letters identify the style of unit heater. These first three
characters must be HD or HDS for it to be convertible.
2. The control code for the unit to be converted must be 34.
3. Finally, the serial number shown in Figure 2.2 calls out the
date the unit was built. Any unit manufactured after the 12th
week of 1998, is acceptable for conversion.
