Modine Manufacturing PD/BD User manual

For Units being Converted from Natural Gas
to Propane Gas Concurrently
Follow carefully the propane conversion instructions, found
in Bulletin 75-511, using the proper high altitude main burner
orifices called out in this literature (75-535) instead of the
orifices in propane conversion kit.
SELECTION OF THE PROPER KIT
To select the proper high altitude kit you need to know the
specifics of the heater you will be converting, and the altitude
it will be going into. If the high altitude kits are ordered at the
same time as the unit heater, all pertinent information relative to
the heater can be obtained from the catalog. If the high altitude
kit is needed after the unit heater is in the field, you need to
refer to the carton label or unit heater serial plate to obtain the
necessary information. Figure 8.2 shows a portion of the unit
heater serial plate where this information may be obtained.
Referring to this figure, the prefix letters and successive
numbers which are needed for kit selection are BV 100. The
letters identify the model and the numbers the size of the unit.
To determine the type of gas the unit is designed for, see the
gas designation disc (Figure 1.1) and the type of gas, located on
the serial plate.
After obtaining this information, refer to the proper selection
chart. The selection charts are differentiated by product type,
altitude and fuel type. Remember, if you are converting from
natural gas to propane gas and want to operate at high altitude,
both a propane conversion kit and a propane high altitude kit
must be used. Selection charts include the proper kit suffix, the
orifice drill size, and the number of orifices required for the unit
being converted. Drill sizes are also stamped on each orifice.
HIGH ALTITUDE CONVERSION
For Existing Natural or Propane Gas Units
Gas-fired equipment ratings are certified by C.S.A. For
elevations above 2000 ft., ANSI Z223.1 requires ratings be
reduced 4 percent for each 1000 ft. above sea level. C.G.A.
requires that ratings be reduced 10% at elevations above 2000
ft. To accommodate higher altitude operation, equipment
must be converted by changing orifices as explained in
this instruction sheet. Tables 2.1 thru 5.2 list orifice kits which
comply with both ANSI Z223.1 recommendations and C.S.A.
requirements.

IMPORTANT
Conversion from natural gas to propane gas is allowed for
PD/BD, PDP/BDP, and PSH/BSH models with 11,12, 30,
or 31 control codes, built in January, 1987 or later. For this
conversion, both a propane conversion kit and a propane
high altitude kit must be used.
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
qualified installation and service agency. All installation
and service of these kits must be performed by a qualified
installation and service agency.
2. These instructions must also be used in conjunction with
the Installation and Service manual originally shipped with
the appliance being converted, in addition to any other
accompanying component supplier literature.
IMPORTANT
As Modine Manufacturing Company has a continuous
product improvement program, it reserves the right
to change design and specifications without notice.

Conversion of any unit is the responsibility of,
and the risk of the person making the conversion.
INSTALLATION
Step 1 Turn off all electricity and gas to unit.
PD/BD, PDP/BDP, PV/BV Models
Lower bottom pan to expose burner and manifold
(see Figure 6.1).
“D”, “H”, “I”, & “O” Models (not including
separated combustion)
Remove weatherproof duct furnace section access
door to obtain access to the manifold assembly (not
applicable on indoor gravity vented models). See
Figure 6.2.
Disconnect gas manifold at the ground joint union (field
supplied ground joint union on DFG and IFG models
equipped with standard control box). Remove the two
screws holding the manifold to the heat exchanger
support. Slide the manifold through the manifold
bracket.

Step 2 Exchange main burner orifice(s) and install air shutters
if provided (see Figure 6.3). Check the orifice number
stamped on each orifice. Be sure that this number is the
same number indicated on the kit parts list for the kit
being installed (see previous tables).
FOR ALL “D”, “H”, “I”, & “O” UNITS, PROCEED
WITH STEP 3.
IF UNIT BEING CONVERTED IS A PD/BD, PDP/BDP,
PSH/BSH PROCEED WITH STEP 4.
Step 3 “D”, “H”, “I”, & “O” Models
Re-install the manifold assembly making certain that it
is correctly positioned.
Step 4 If a new pressure switch is supplied with your kit,
remove the old pressure switch and install the new
one in it's place. Reconnect the pressure line to the
new switch.
WARNING
1. Disconnect power and gas supply before making
conversion.
2. 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.

Figure 7.3 - High Altitude Conversion Label
Figure 7.2 - Lifting Flame
Step 5 On the High Altitude Conversion Label (see Figure
7.3) write the drill size, as stamped on orifice, with a
permanent marker. Be sure to check correct orifice size
using the selection instructions beginning on
page 1.
Affix the High Altitude Conversion Label (Figure 7.3)
adjacent to the units serial plate.
Step 6 Restore fuel supply to the unit.
Step 7 Check gas supply pressure at unit upstream from
combination gas control. The supply pressure should
be 6" - 7" W.C. on natural gas or 11" - 14" W. C. on
propane gas.
Step 8 Connect the manometer (or gauge) to the outlet
pressure tap on the combination gas control.
Step 9 Restore electric supply to unit.
Step 10 Follow lighting instructions on unit. Turn up thermostat
setting to call for heat. After the main burners light,
measure the outlet (manifold) pressure of the
combination gas control. The pressure should be 3.5
in. W.C. for natural gas and 10 in. W.C. for propane
gas. The outlet pressure can be adjusted at the
control’s regulator. Turning the adjustment clockwise
will increase the outlet pressure while turning it
counterclockwise will decrease the pressure.

INSTALLATION
Step 11 Check for leaks at all joints and connections in the
gas lines. This is most easily done with a soap/water
solution. Simply brush or spray some of the solution
on a joint or connection and look for bubble formation.
Step 12 Observe the main burner flame. The flame should
have a well-defined conical shape with the base
anchored to the burner port. If the flame appears to be
lifting or rising above the burner port (see Figure 7.2),
loosen the thumb screw on the air shutter and slide
the shutter forward toward the mixer tube (Figure 6.3).
If a majority of the flame is yellow, move the air shutter
back away from the mixer tube. Slight yellow tips on a
propane flame are common and are not objectionable.
For more specific flame control adjustment
instructions, see the Installation and Service Manual
which came with your unit.
Conversion of the unit is complete.
